We show that chromatin assembly concurrent with DNA synthesis over the promoter region itself is causal for repression. However, the trans-activator Gal4-VP16 both relieves repression and activates transcription regardless of the chromatin assembly pathway. This activation is independent of whether Gal4-VP16 addition occurs before or after chromatin assembly. We propose that replication-coupled chromatin assembly represents a general mechanism to direct the efficient repression of basal transcription. However transcription induction by a specific activator, Gal4-VP16, occurs independent of this chromatin-mediated repression. C1 NICHHD,MOLEC EMBRYOL LAB,BETHESDA,MD 20892.

Because overexpression of a low abundance tRNA-Arg(CCU) encoded by the HSX1 gene resulted in a reduction in Ty1 frameshifting, it was suggested that a translational pause at the AGG-Arg codon is required for optimum frameshifting. The present work shows that the absence of tRNA-Arg(CCU) affects Ty1 transposition, translational frameshifting, and accumulation of mature TYB1 proteins. Transposition of genetically tagged Ty1 elements decreases at least 50-fold and translational frameshifting increases 3-17-fold in cells lacking tRNA-Arg(CCU). Accumulation of Ty1-integrase and Ty1-reverse transcriptase/ribonuclease H is defective in an hsx1 mutant. The defect in Ty1 transposition is complemented by the wild-type HSX1 gene or a mutant tRNA-Arg(UCU) gene containing a C for T substitution in the first position of the anticodon. Overexpression of TYA 1 stimulates Ty 1 transposition 50-fold above wild-type levels when the level of transposition is compared in isogenic hsx1 and HSX1 strains. Thus, the HSX1 gene determines the ratio of the TYA 1 to TYA 1 -TYB 1 precursors required for protein processing or stability, and keeps expression of TYB1 a rate-limiting step in the retrotransposition cycle.

Elderly normal controls generated more uncommon exemplars from closed semantic categories (fruits and vegetables) than did AD patients 2 1/2 years prior to the presumed onset of AD. AD patients, however, were just as productive as elderly normal controls in generating associations to open categories (letters). The findings suggest that one of the early cognitive symptoms of AD is changes in availability of uncommon exemplars of semantic networks. C1 JOHNS HOPKINS UNIV,DEPT NEUROL,BALTIMORE,MD 21218.

Three groups totaling 69,988 men were the subjects of the cohort study: group 1 comprised men hospitalized with hepatitis in 1942, group 2 comprised men subclinically infected in 1942 and group 3 comprised controls who entered service after the contaminated vaccine was discontinued. Hepatocellular carcinoma cases (n = 24) and control subjects (n = 63) derived from Veterans Affairs hospital discharge files were the subjects of the case-control study. Group comparisons of death rates from liver cancer were refined by expert review of records to select hepatocellular carcinoma from among all causes of death so diagnosed in the cohort study. Slightly excess mortality was found for hepatocellular carcinoma in group 2 (subclinical hepatitis B) but not for group 1 (overt hepatitis B) compared with group 3 (controls) (p = 0.08). Mortality from nonalcoholic chronic liver disease was less in group 2 than in group 3. In the case-control study, the relative risk for hepatocellular carcinoma conferred by receipt of contaminated vaccine was estimated as 3.3 (p = 0.06). We conclude from the cohort study that immunocompetent adult males rarely become carriers after hepatitis B virus infection, probably far less often than the frequently assumed rate of 5% to 10%. The small excess liver cancer mortality seen in the cohort study and the results of the case-control study are consistent, nevertheless, with the now well-established etiological role of hepatitis B virus infection in liver cancer.

Most importantly, the vast majority of patients with a clinical diagnosis of halothane hepatitis have serum antibodies. which react with one or more specific liver microsomal proteins that have been covalently altered by the trifluoroacetyl chloride metabolite of halothane. The serum antibodies are specific to halothane hepatitis patients and are not seen in sera of patients with other types of liver pathology. In this study, a 57-kD trifluoroacetylated liver microsomal neoantigen associated with halothane hepatitis and native 57-kD protein were purified from liver microsomes of halothane-treated and -untreated rats, respectively. When the purified trifluoroacetylated 57-kD and native 57-kD proteins were used as test antigens in an enzyme-linked immunosorbent assay, serum antibodies from halothane hepatitis patients (n = 40) reacted with both of these proteins to a significantly greater extent than did serum antibodies from control patients (n = 32). On the basis of its apparent monomeric molecular mass, isoelectric point and NH2-terminal amino acid and tryptic peptide sequences. the 57-kD protein has been identified as rat liver protein disulfide isomerase. Antibodies raised against rat liver protein disulfide isomerase also reacted with a protein of approximately 58-kD in human liver microsomes. The results of this investigation suggest that trifluoroacetylated protein disulfide isomerase is one of the immunogens associated with halothane hepatitis. In certain patients it might lead either to specific antibodies or, possibly, to specific T cells, which could be responsible for halothane hepatitis.

Medium from infected primate fibroblasts and endothelial cells contained the highest viral titers [10(4)-10(5) focus-forming units (ffu)/ml], while most hematopoietic cell lines, such as K562 and MOLT4, were associated with viral titers in the range of 10(-3)-10(4) ffu/ml. Interestingly, HTLV-1-transformed T cell lines (TJF-2 and HM) and primary tumor infiltrating lymphocytes (TIL) had very low viral titer (0-10(1) ffu/ml). The low production of virus was not due to low infectivity and, in contrast to the virus, retroviral vectors were expressed without difficulty. Because screening for replication-competent retrovirus (RCR) is an important component of human retroviral-mediated gene therapy clinical protocols, a variety of assays were tested for their ability to detect RCR in virus-exposed cell lines. A biologic assay (3T3 amplification) and polymerase chain reaction (PCR) for the 4070A viral envelope are effective screening methods for RCR, even in cell lines associated with low virus production.

T cells from each seronegative twin will be obtained by periodic apheresis, separated into CD4 and CD8 enriched populations by monoclonal antibody affinity binding techniques, induced to polyclonal proliferation with anti-CD3 and rIL-2 stimulation, transduced with distinctive neoR retroviral vectors, and expanded 10-1,000 fold in numbers during approximately 2 weeks of culture. These marked T cell fractions will then be infused into the seropositive twins and the survival of the uniquely marked T cell populations will be monitored by vector-specific PCR, while the recipients' functional immune status is monitored by standard in vitro and in vivo testing protocols. A total of 3 cycles of treatment will be given at intervals of 6 weeks between infusions. C1 NCI,DCBD,BETHESDA,MD 20892. RP WALKER, R (reprint author), NIAID,LIR,BETHESDA,MD 20892, USA.

The interval RAF1-D3S18 (3p25-3p26) has been identified by genetic linkage studies to harbour the von Hippel-Lindau gene. We have constructed a long range restriction map of this region and have succeeded in demonstrating the physical linkage of loci D3S726 (DNA probe LIB31-38), D3S18 (c-LIB-1, L162E5), D3S601 (LIB19-63) and D3S587 (LIB12-48). Since multipoint analysis has located D3S601 proximal to D3S726, the physical map should be oriented with D3S726 towards the telomere. The order and distances of probes within the von Hippel-Lindau gene region is as follows: telomere - LIB31-38 - (<280 kb) - c-LIB-1 - (overlapping) - L162E5 - (900-1600 kb) - (LIB19-63, LIB12-48) - centromere. In tissues that included blood, semen and Epstein-Barr-virus-transformed lymphocytes, we detected a putative CpG island flanking D3S18.

Previous work demonstrated that the 5'-terminal 100 base pairs of the human LINE-1 element (L1Hs) has an important role in regulating it's expression. Here we report further deletion analysis revealing the presence of a cis regulatory element overlapping the region between base pairs + 12 and + 18. Oligonucleotides containing this sequence form a specific complex with a nuclear protein extracted from NTera2D1 and Jurkat cells, and with recombinant YY1 produced in E. coli. The complex is competed by YY1 binding sites found in other genes, and is ablated by anti-YY1 serum. These results suggest that YY1 is involved in the regulation of Ll Hs transcription and therefore transposition. C1 NIAID,MOLEC GROWTH REGULAT LAB,BETHESDA,MD 20892.

Electromechanical activities in the uterine wall were recorded using bipolar silver-silver electrodes, endoluminal pressure catheters and a dedicated acquisition, storage and analytical system. The electrical signals recorded were isolated spikes and rhythmic activities; the last being primarily associated with organized mechanical events. Perfusion media containing 17beta-oestradiol alone or with progesterone were used for those uteri obtained during proliferative (n = 5) or secretory (n = 5) phases of the menstrual cycle, respectively. Progesterone caused a reduction of frequency (P < 0.001) and duration (P < 0.001) of the rhythmic electrical activity, and decreased the endoluminal pressure at both detection sites (P < 0.01). 17beta-Oestradiol increased both frequency (P < 0.001) and duration (P < 0.001) of the rhythmic electrical activity as well as the endoluminal pressure at two different detection sites (3 and 5 cm from the fundus) (P < 0.05). Significant differences between the fundus and cervix sites in the uterine wall were detected. In conclusion, uterine perfusion would be useful to examine the effects of uterotonic and tocolytic drugs before administration to humans, at no risk to the patients. Oestrogens increase and progesterone decreases both electrical and mechanical uterine activities. C1 UNIV BOLOGNA,BELLARIA HOSP,DEPT MED,I-40100 BOLOGNA,ITALY.

Six centers tested an intervention designed to reduce dietary sodium to 80 mmol (1800 mg)/24 h with a total of 327 active intervention and 417 control subjects. The intervention consisted of eight group and two one-to-one meetings during the first 3 months, followed by less-intensive counseling and support for the duration of the study. The mean net decrease in sodium excretion was 43.9 mmol/24 h at 18 months. Women had lower sodium intake at baseline and were therefore more likely to decrease to less than 80 mmol/24 h. Black subjects were less likely to decrease to less than 80 mmol/d, independent of sex or baseline sodium excretion. The mean (95% confidence interval) net decrease associated with treatment was -2.1 (-3.3, -0.8) mm Hg for systolic blood pressure and -1.2 (-2.0, -0.3) mm Hg for diastolic blood pressure at 18 months (both P<.01). Multivariate analyses indicated a larger systolic blood pressure effect in women (-4.44 versus -1.23 mm Hg in men), adjusted for age, race, baseline blood pressure, and baseline 24-hour urinary sodium excretion (P=.02). Dose-response analyses indicated an adjusted decrease of -1.4 mm Hg for systolic blood pressure and -0.9 mm Hg for diastolic blood pressure for a decrease of 100 mmol/24 h in 18-month sodium excretion. These results support the utility of sodium reduction as a population strategy for hypertension prevention and raise questions about possible differences in dose response associated with gender and initial level of sodium intake.

In this study, the relationship between IL-2 production and the protein tyrosine phosphorylation pattern of human Jurkat T cells was investigated using phosphotyrosine immunoblotting analysis. With anti-CD3 or anti-CD2 activation the cells showed only a low (anti-CD3) or a moderate (anti-CD2) level of tyrosine phosphorylation of a 42,000 MW external signal-regulated kinase (ERK), which was accompanied by undetectable (anti-CD3) or low level (anti-CD2) IL-2 production. In the presence of phorbol myristate acetate (PMA), large amounts of IL-2 were induced by both anti-CD3 and anti-CD2 stimulation, which was accompanied by strong concurrent tyrosine phosphorylation of the 42,000 MW ERK and a 100,000 MW protein. PMA alone, which induced high levels of tyrosine phosphorylation of the ERK protein, neither induced any detectable IL-2 nor increased the level of tyrosine phosphorylation of the 100,000 MW protein. These observations suggest that concurrent tyrosine phosphorylation of the 42,000 MW ERK and a 100,000 MW protein may be required for IL-2 production.

During the first 3 weeks following infection, NK activity was well conserved, but by 9-12 weeks post-infection (p.i.), killer activity was depressed: however, the frequency of NK-1.1+ cells increased within 4 weeks of infection and remained elevated thereafter, even following the decline in functional killing activity. Since the absolute number of NK-1.1 + cells increased after infection, the ability of each NK-1.1+ cell to kill the targets seems drastically impaired. Extraordinary expansion of NK-1.1-positive cells was induced by infection with LP-BM 5-defective virus (BM5def), a crucial element for MAIDS induction, but not with a helper non-pathogenic virus. With advance of MAIDS the NK-1.1 antigen (Ag) was preferentially expressed on B220+ and Thy-1+ cells, in contrast to CD4+ and CD8+ cells, and among activated large cells a higher proportion was NK-1.1- than NK-1.1-. Mice with graft-versus-host disease (GVHD) due to class II major histocompatibility complex (MHC) Ag disparity showed a high frequency of NK-1.1 expression in association with other phenotypic alterations, very similar to those seen in mice with MAIDS. In contrast, B6-lpr/lpr mice developed similar activation of B cells but did not exhibit enhanced expression of the NK-1.1 marker. Thus, enhanced expression of the NK-1.1 Ag might be associated with chronic activation of lymphocytes through a common but not universal pathway. C1 NIH,IMMUNOPATHOL LAB,BETHESDA,MD 20892.

This longitudinal study examined the antecedents of variation among 13-month-old toddlers in these exploratory competencies in the infants' own information-processing abilities at 5 months (indexed by visual fixation in the laboratory), the infants' vocal and exploratory activities at 5 months (measured during naturalistic observation in the home), mothers' stimulation of infants at 5 months, and mothers' IQ. Infant visual fixation and maternal IQ predicted toddler symbolic play; furthermore, infant visual fixation, infant activity, and maternal IQ predicted toddler attention span. In contrast, mothers' early stimulation did not predict ploy or attention in toddlers. Structural equation modeling was used to assess prediction of the three significant antecedents (infant visual fixation, infant activity, and maternal IQ) to toddlers' exploratory competence, a latent variable representing the shared variance between play and attention. Together, the three predictors accounted for 50% of the variance in toddler exploratory competence. These data broaden the scope of infant and mother prediction beyond toddler verbal-representational abilities to encompass domains of toddler exploration. C1 NICHHD,BETHESDA,MD 20892.

To assess whether it assembled into a conformationally correct structure at the cell surface, we characterized the recombinant MOMP (rMOMP) by Western immunoblot analysis, indirect immunofluorescence, and immunoprecipitation with monoclonal antibodies (MAbs) that recognize contiguous and conformational MOMP epitopes. Western blot analysis showed that most of the rMOMP comigrated with authentic monomer MOMP, indicating that its signal peptide was recognized and cleaved by E. coli. The rMOMP could not be detected on the cell surface of viable or formalin-killed E. coli organisms by indirect immunofluorescence staining with a MAb specific for a MOMP contiguous epitope. In contrast, the same MAb readily stained rMOMP-expressing E. coli cells that had been permeablized by methanol fixation. A MAb that recognizes a conformational MOMP epitope and reacted strongly with formalin- or methanol-fixed elementary bodies failed to stain formalin- or methanol-fixed E. coli expressing rMOMP. Moreover, this MAb did not immunoprecipitate rMOMP from expressing E. coli cells even though it precipitated the authentic protein from lysates of C. trachomatis elementary bodies. Therefore we concluded that rMOMP was not localized to the E. coli cell surface and was not recognizable by a conformation-dependent antibody. These results indicate that rMOMP expressed by E. coli is unlikely to serve as an accurate model of MOMP structure and function. They also question the utility of rMOMP as a source of immunogen for eliciting neutralizing antibodies against conformational antigenic sites of the protein.

Epitopes on the major outer membrane protein (MOMP) of C. trachomatis have been identified as important targets for the development of vaccines. In order to examine the immunogenicity of a recombinant vector expressing a chlamydial epitope, a poliovirus hybrid was constructed in which part of neutralization antigenic site I of poliovirus type 1 Mahoney (PV1-M) was replaced by a sequence from variable domain I of the MOMP of C. trachomatis serovar A. The chlamydial sequence included the neutralization epitope VAGLEK. This hybrid was viable, grew very well compared with PV1-M, and expressed both poliovirus and chlamydial antigenic determinants. When inoculated into rabbits, this hybrid was highly immunogenic, inducing a strong response against both PV1-M and C. trachomatis serovar A. Antichlamydia titers were 10- to 100-fold higher than the titers induced by equimolar amounts of either purified MOMP or a synthetic peptide expressing the VAGLEK epitope. Furthermore, rabbit antisera raised against this hybrid neutralized chlamydial infectivity both in vitro, for hamster kidney cells, and passively in vivo, for conjunctival epithelia of cynomolgus monkeys. Because poliovirus infection induces a strong mucosal immune response in primates and humans, these results indicate that poliovirus-chlamydia hybrids could become powerful tools for the study of mucosal immunity to chlamydial infection and for the development of recombinant chlamydial vaccines.

These viruses depend on the host cell machinery for their existence, and interference with these processes typically interferes with other important host physiology. HIV presents other challenges as well because of its inherent pathogenic destruction of the immune system. It is the goal of HIV therapeutics to attempt to cure HIV infection, or if that is not possible, to stop HIV disease progression while preserving a high quality of life for HIV-infected individuals. This may be achieved through an effective combination of interference with the viral life cycle and the pathogenic processes, and by slowing or reversing the immunologic dysfunction that leads to the complications of HIV infection. Unprecedented progress has been made in understanding the virus and HIV disease pathogenesis. This knowledge has led to the identification of viral features that have become targets for therapeutic intervention. This article reviews the most important priorities of HIV treatment research for adult HIV-infected patients for the immediate future. These priorities include the following: development of new antiretroviral compounds and their application as both monotherapies and in combination therapy approaches; immune-based therapeutic approaches; and research and treatment for acute or primary HIV infections.

To measure the reliability of passive smoking histories, re-interviews were conducted for 110 subjects (37 cases and 73 controls) as part of a larger study of lung cancer among non-smoking women in Missouri. Agreement was high both for parental smoking status (94% concordance; kappa = 0.82) and for spousal smoking status (84% concordance; kappa = 0.67). Concordance also was relatively high for cigarette pack-years of exposure due to the parents or spouse. Reliability tended to be somewhat higher among controls than among cases, and for exposure due to a parent or spouse than for that due to other household members. Questions on the perceived harmfulness of passive smoke exposure showed no differences between cases and controls. These findings indicate a high degree of repeatability in responses regarding passive smoking, but also suggest the potential for misclassification of passive smoke exposure status, the desirability of standardized questions on passive smoking, and the need for additional studies of reliability and validity.

To understand the ETS1 function in non-lymphoid cells, we have ectopically expressed ETS1 protein in a human colon cancer cell line, and studied its biochemical properties. The 51 kDa ETS1 protein expressed in transfected cells localized in both the nucleus and the cytoplasm, has similar biochemical properties compared to ETS1 protein expressed in lymphoid cells. The ectopically expressed ETS1 binds to the DNA in sequence-specific manner and the binding activity is affected by the flanking sequences outside the 'GGA' core. Our results also demonstrate that the DNA-binding activity of full-length ETS1 is similar in lymphoid and non-lymphoid cells. The ETS1 expressed in DLD-1 cells is biologically active since it induces a 54.5 kDa polypeptide, whose expression level correlates with the expression of ETS1 in DLD-1 cells.

RHEK-1 keratinocytes were used as a prototype to determine mutagen treatment conditions, plating density, and phenotypic expression time for maximum recovery of thioguanine-resistant mutants. Mutation frequency was measured after exposure to ionizing radiation or to polycyclic aromatic hydrocarbons. 7,12-Dimethylbenz[a]-anthracene and benzo[a]pyrene caused almost no cytotoxicity, but induced thioguanine-resistant mutants at frequencies as much as 30 to 40-fold higher than the median spontaneous frequency of 7 x 10(-6). X-irradiation was also an efficient mutagen in RHEK-1 keratinocytes. The mutants were aminopterin-sensitive and possessed no measurable hypoxanthine-guanine phosphoribosyltransferase activity. The RHEK-1 human epithelial cell line is therefore useful for the study of induced mutation at a defined genetic locus as well as being an important model for the investigation, of molecular, cellular and genetic mechanisms of neoplastic transformation in human stratified squamous epithelia.

Recent studies have indicated that certain aldose reductase inhibitors prevent the formation of cataracts in naphthalene-fed rats. The study was designed to investigate whether aldose reductase itself is involved in the metabolism of naphthalene in the lens and the mechanism of this cataract formation. Methods. Aldose reductase was purified from whole rat lens using a series of chromatographic steps that include gel filtration, affinity chromatography, and chromatofocusing. The dehydrogenase activity of the purified enzyme was evaluated with 1,2-dihydro-1,2-dihydroxynaphthalene (naphthalene dihydrodiol) as substrate. The same dehydrogenase activity was also examined with the recombinant protein obtained from rat lens aldose reductase clone. Results. Throughout the purification steps, dehydrogenase activity with naphthalene dihydrodiol as substrate coeluted with aldose reductase activity assayed with DL-glyceraldehyde as substrate. The purified aldose reductase, which appeared as a single band on sodium dodecyl sulfate-polyacrylamide gel electrophoresis, displayed dehydrogenase activity with naphthalene dihydrodiol as a substrate similar to that observed with the crude extract from whole rat lens. Recombinant protein from rat lens aldose reductase clone also displayed dehydrogenase activity similar to that observed with purified rat lens aldose reductase. Both the reductase and dehydrogenase activities of purified aldose reductase were inhibited by aldose reductase inhibitors. However, inhibition of dehydrogenase activity was less than reductase activity. Aldehyde reductase, an another nicotinamide adenine dinucleotide phosphate-dependent reductase, also displayed dihydrodiol dehydrogenase activity with naphthalene dihydrodiol and this activity was also inhibited by aldose reductase inhibitors. Conclusions. Aldose reductase displays dehydrogenase activity in addition to reductase activity. In rat lens aldose reductase is a major protein associated with naphthalene dihydrodiol dehydrogenase activity. This suggests that aldose reductase is linked to 1,2-dihydroxynaphthalene formation in rat lens and the subsequent formation of cataracts in naphthalene-fed rats.

The presence of nasal discharge on a child's face increases the risk of active trachoma, suggesting that Chlamydia trachomatis in nasal secretions may be a possible source of ocular reinfection. The prevalence of chlamydia in nasal secretions and the risk of reinfection after mass treatment was investigated in a hyperendemic area of Tanzania. Methods. In one village a total of 232 children aged 1 to 7 years were followed before and after mass treatment. Clinical trachoma, and microbiologic evidence of chlamydia, were assessed at baseline, 2 and 4 weeks into mass treatment, and 4 weeks after treatment stopped. The presence of chlamydia in ocular and nasal secretions was determined by polymerase chain reaction-enzyme immunoassay techniques. Results. Of the 232 children, 59% had clinical trachoma and 27% had nasal specimens positive for chlamydia. Children with positive ocular chlamydia specimens and/or clinical trachoma were significantly more likely to have positive nasal specimens. At the end of mass treatment, only 4% of children had positive ocular specimens. However, 1 month after treatment stopped, the incidence of new infection was 2 1%. The rate of new ocular infections in those who had-negative ocular specimens after treatment was similar between those who had positive and those who had negative nasal specimens at baseline. Positive ocular specimens at baseline was not a predictor of risk of new infection after treatment (odds ratio = 1. 18, 95% confidence interval = 0.58, 2.40), suggesting these new infections were not the result of latent or persistent organism. Conclusions. These data do not support a role for nasal secretions in causing reinfection after treatment. One mass topical treatment alone is unlikely to be effective in trachoma hyperendemic areas as shown by the rapid re-emergence of infection.

Participants included journal editors, educators from psychology and psychiatry, representatives from private foundations, and leaders of research program areas in public funding agencies. Critical knowledge gaps were identified in five areas of child and adolescent psychopathology, including depression, attention deficit hyperactivity disorder, conduct disorder, the anxiety disorders, and the developmental disorders. For each of these areas, special emphasis was placed on developing new ideas and obtaining critical input from other areas of investigation. This report summarizes the identified research gaps and recommends research initiatives to implement the National Plan, as outlined by the conference participants.

The results indicate that dosing frequency is extremely important for drug efficacy. The monkeys were divided into three groups based on dosing frequencies of 6-, 8-, or 12-h intervals. All were given a total daily dose of 100 mg/kg of ZDV. The drug was administered subcutaneously starting 24 h before SIV inoculation, and treatment continued for an additional 28 days. With the total daily dose held constant, ZDV was most therapeutic when administered at 12-h intervals, less effective at 8-h intervals, and least effective at 6-h intervals. These results indicate that early ZDV treatment based on infrequent but high dosages may increase the antiretroviral effect of the drug. These findings could serve as a model for ZDV chemoprophylaxis in humans. In cases involving accidental exposure to SIV or human immunodeficiency virus (HIV-1 or HIV-2), immediate, high-dosage therapies may be most therapeutic.

To that end, we conducted a randomized, double-blind, outpatient trial comparing subjects treated with 400 mg per kilogram of IVIG every 28 days with those given 0.1% albumin placebo. CD4+ counts were measured at entry and every 12 weeks. Twenty-eight clinical centers in mainland United States and Puerto Rico participated. Previous reports showed IVIG efficacy for infection prophylaxis in 313 patients with entry CD4+ counts of greater-than-or-equal-to 0.20 x 10(9)/L (greater-than-or-equal-to 200/mm3). Two hundred and seventy-seven (89%) of these 313 children had three or more CD4+ counts measured during the trial and were included in evaluation of CD4+ count trends. Rates of CD4+ count decline, as measured by regression slopes, were compared between IVIG and placebo groups using generalized linear models, comparing unadjusted, age-adjusted, and standardized age-adjusted data. Potential covariate effects were assessed by modeling change in CD4+ count in terms of log change between successive measurements. Age-adjusted slope analysis showed slowing of CD4+ count decline by 13.5 cells/mm3 per month in IVIG compared with placebo recipients (95% confidence interval, 3.1-23.9, p = 0.012). Modeling log change between measurements documented a beneficial effect of IVIG that was cumulative over time and independent of other therapies. Occurrence of serious bacterial infection in the interval before CD4+ count measurement or death was independently associated with more rapid CD4+ count decline (p = 0.01 and p = 0.008, respectively). Zidovudine therapy was associated with a transient increase in CD4+ count. Benefits of IVIG include slowing of CD4+ count decline as well as previously reported reductions in serious and minor bacterial and viral infections in subjects with entry CD4+ counts of greater-than-or-equal-to 0.20 x 10(9)/L. This finding provides corroboration for the hypothesis that immunologic mechanisms contribute to the pathogenesis of CD4+ decline in HIV infection. C1 WESTAT CORP,ROCKVILLE,MD.

Of 2,329 women, 81 (3.5%) were HTLV-1 seropositive. Two to three years later, 36 seropositive mothers were recontacted, and blood was drawn from them and their children. All sera were tested for HTLV-1 antibodies, and mother's sera were additionally tested for HTLV-1 whole-virus antibody titer, syncytium-inhibition neutralizing antibody titer, and titers to six synthetic peptides from the HTLV-1 envelope glycoprotein gp46. Seventeen of 74 (23%) [95% confidence interval (CI) 15-34%] children were seropositive. HTLV-1 transmission was associated with breast-feeding duration > 6 months [relative risk (RR) 3.2; CI 0.4-22.1], maternal age > 30 years (RR 2.8; CI 1.0-7.8), and higher maternal whole-virus antibody titer (RR 3.3; CI 1.3-8.5). After controlling for higher whole-virus antibody titer, transmission remained associated with higher titer of neutralizing antibody and higher titer of antibody to the peptide sp4a1, corresponding to amino acids 196-209 of the gp46 envelope glycoprotein. We conclude that mother-to-child transmission of HTLV-1 in Jamaica is associated with longer duration of breast-feeding, older age, and higher HTLV-1 antibody titer, in particular to a certain immunogenic portion of the gp46 envelope glycoprotein.

The question is relevant to our understanding of gender differences in the phenomenology of depression, and of changes in the sleep-activity cycle that are seen in affective illness and during the menopause. In this paper, the literature demonstrating that gonadal steroids regulate circadian rhythms in animals is reviewed, along with the limited human literature. A hypothesis is forwarded suggesting that, in humans, estrogen shortens the circadian period, lengthens the sleep phase, advances sleep onset, and consolidates sleep. A study in progress is described which is designed to test the effects of the hypogonadal state, estrogen, and progesterone on circadian rhythms in women.

Methods: Fifteen subjects with mastocytosis participated in a double-blind, randomized, three-period, crossover trial, which compared an azelastine regimen of 4 mg or 8 mg every 12 hours with a chlorpheniramine regimen of 12 mg every 12 hours. Response to therapy was assessed by daily symptom scores, extinction dilution skin tests, plasma histamine levels, and global evaluations. Results: Subjects' mean wheal area responses provoked by histamine or morphine sulfate were significantly lowered by azelastine when compared with chlorpheniramine. Plasma histamine levels in subjects receiving azelastine or chlorpheniramine were not significantly different. There were no significant differences between azelastine and chlorpheniramine in individual symptom scores or global evaluations except that azelastine at both doses significantly relieved pruritus and at 4 mg significantly relieved abdominal pain and that chlorpheniramine was associated with less fatigue in comparison to azelastine at 8 mg. Conclusions: It thus appears that azelastine is superior to chlorpheniramine in suppressing skin responses to histamine and morphine sulfate and in suppressing pruritus in patients with mastocytosis. However, when all parameters are considered, neither drug is clearly superior for the treatment of patients with mastocytosis.

Methods and Results: To explore the biologic potential of Ab-2 as diagnostic reagents in allergic diseases, murine mouse (m) Ab-2 were raised by immunizing Balb/c mice with affinity purified rabbit (r) Ab-1 specific for the pollen of Parthenium hysterophorus, an allergenic weed that grows wild on the Indian subcontinent and in Australia, Mexico, and the southern United States. Affinity purified Parthenium-specific human (h)AB-1 could successfully inhibit the binding of mAb-2 to immobilized rAb-1. Further, Balb/c mice immunized with mAb-2 induced Parthenium-specific anti-anti-idiotypic IgE and IgG antibodies. Specificity of the Ab-2 was confirmed by the ability of Parthenium pollen extracts to inhibit the binding of allergen-specific IgE and IgG Ab-1 in the sera of patients with rhinitis to immobilized mAb-2. Parthenium-sensitive patients with rhinitis who had positive results on skin prick tests to Parthenium pollen extracts also responded with a positive skin reaction to mAb-2. Conclusion: Our data demonstrate that Parthenium-specific mAb-2 may be of value as surrogate allergens in allergen standardization and for in vitro diagnosis.

Kushner et al. (Am. J. Clin. Nutr. 56: 835-839, 1992) showed that the relationship between height2/resistance and total body water (TBW) is robust across a wide age range, although uncertainty remained over the relationship in preschool children. We therefore cross-validated the Kushner equation for predicting total body water in 4- to 6-yr-old children in two independent laboratories. TBW was measured from (H2O)-O-18 dilution, and bioelectrical resistance and reactance were measured using an RJL 101A analyzer in 31 children (15 females, 16 males; 5 +/- 0.8 yr) studied in Burlington, Vermont, and 30 children (14 females, 16 males; 5 +/- 0.2 yr) studied in Phoenix, Arizona. There was no significant difference between TBW predicted from the Kushner equation and that measured in children in Burlington (11.76 +/- 2.00 vs. 11.91 +/- 2.46 kg, r = 0.94) or in Phoenix (11.53 +/- 1.64 vs. 11.66 +/- 1.90 kg; r = 0.94). The Kushner equation for TBW can be transformed into an equation for fat-free mass (FFM) by using published age- and gender-specific constants for the hydration of FFM: hydration of FFM = 76.9 - 0.25 age (yr) - 1.9 gender where female equals 0 and male equals 1. The intraclass reliability for estimates of fat mass and FFM with the use of bioelectrical resistance in an independent group of 26 children (5.0 +/- 0.8 yr, 20.2 +/- 3.0 kg) was >0.99 for duplicate observations performed 2 wk apart. We conclude that the relationship between TBW and height2/resistance in young children is robust across independent laboratories and that the Kushner equation relating these two variables is viable in young children.

If the amino acids composing the motifs are contiguous in the primary chain, that is, they follow each other in the sequence, a common ancestor and a divergent evolutionary process may be implied. On the other hand, if the three-dimensional substructural motif consists of amino acids whose positions in the sequences vary between the different proteins, a convergent evolution might have taken place. Starting from different, ancient sequences, mutations may have occurred that brought about formation and conservation of a truly structural motif. Such a motif might be particularly suitable for fulfilling a specific function. Clearly, in order to be able to carry out such a task one needs a technique which allows comparisons of protein structures absolutely independent of their amino acid sequence-order. Our novel, efficient, computer vision based technique treats atoms (residues) as unconnected points in space, using strictly the atomic (either all atoms or only the Ca atoms) coordinates. The order of the residues is completely disregarded. Detection, cataloging and analysis of 'real' three-dimensional, sequence-order independent motifs in the crystallographic database is expected to be an invaluable tool for protein folding. Here we demonstrate the power of the technique by applying it to alpha/beta proteins. Our studies indicate that for some of the proteins, the 'classical' structural alignments (conserving the amino acid order) are the optimal ones. Nevertheless, for others, truly spatial (out of sequential-order) amino acid equivalencing results in a better geometrical match.

We used tartrate-resistant acid phosphatase (TRAP) to begin to investigate the regulation of bone resorption at the molecular level. TRAP is expressed at high levels in osteoclasts and may play an important role in the bone resorptive process. Therefore, we isolated the murine TRAP gene from a mouse spleen genomic library and characterized its promoter. A restriction map was generated for the 17 kb TRAP insert. A 2 kb SmaI fragment, containing the 5'-flanking region, was subcloned and the nucleotide sequence determined. Sequence analysis of the SmaI fragment revealed the presence of numerous candidate transcription factor binding sequences, including those for AP1 and H-APF-1. The H-APF-1 site matches the consensus sequence for the IL-6-regulated transcription factor. An intron was identified at -1 to -393 bp relative to the ATG. The presence of an intron was confirmed by PCR analysis of RNA isolated from murine osteoclasts. Primer extension analysis indicated the presence of a transcription initiation site at -552 bp from the ATG. The region from -1846 to 2 bp relative to the ATG initiation codon drove the transient expression of a luciferase reporter gene when transfected into HRE H9 rabbit endometrial cells. PMA treatment of HRE H9 cells enhanced luciferase transcription approximately threefold. These data suggest that the TRAP promoter is complex and contains multiple regulatory elements. The availability of the TRAP promoter may also permit production of transgenic mice, which can be used to develop previously unavailable osteoclast cell lines.

At the highest dose, cocaine decreased blood pressure (BP) and heart rate (HR), while QRS duration, an index of cocaine's local anesthetic effect, was increased. Cocaethylene, a metabolite produced after coadministration of cocaine and ethanol, had effects comparable to those of cocaine. The cocaine metabolite norcocaine produced a decrease in BP at the lower dose that reversed to a small increase at the higher dose. The highest dose of norcocaine clearly decreased HR and increased QRS duration. The increases in QRS duration observed for cocaine, cocaethylene, and norcocaine were reversed by sodium bicarbonate. The cocaine metabolites benzoylecgonine and ecgonine methyl ester increased BP at the higher doses without affecting either HR or QRS duration. These results suggest that the spectrum of effects produced by cocaine are not necessarily mimicked by its metabolites. In particular, accumulation of the persistent, active metabolites benzoylecgonine and ecgonine methyl ester may contribute to delayed-onset, cocaine-related toxicity.

The drug-resistant subline was derived from MCF-7 cells by selection with Adriamycin in the presence of the P-glycoprotein antagonist, verapamil, to prevent acquisition of the classical multidrug resistance phenotype. The Adriamycin-resistant cells retain estrogen-binding, estrogen-responsive monolayer growth, and estrogen-dependent tumorigenesis. Estrogen-binding studies demonstrate 1.4 x 10(6) sites per cell with unaltered affinity when compared to parental MCF-7 cells, which have 2.7 x 10(5) sites per cell. Ah increase in expression of EGF receptor, eight to 12-fold, occurred early in the selection for drug resistance, and appears to be unrelated to verapamil exposure, since cells maintained in Adriamycin without verapamil also have increased EGF receptor expression. Partially drug-sensitive revertants carried a verapamil, but out of Adriamycin, demonstrate a decline in EGF receptor expression. We postulate that activation of growth factor pathways in drug-resistant cells may enhance mechanisms of drug resistance, or provide mitogenic stimuli for cells to recover after damage by drug exposure.

We have characterized integrin-type cell adhesion/migration receptors in human mucosal keratinocytes and examined their function in the regulation of type IV collagenase gene expression. Two major integrins of the beta1 class, alpha2beta1 and alpha3beta1, were found to function as collagen and fibronectin receptors, respectively. Antibodies against beta1 and alpha3 integrin subunits were found to stimulate the expression of the 92 kDa type IV collagenase severalfold in a dose-dependent manner. Keratinocytes expressed also the 72 kDa type IV collagenase, the synthesis of which remained, however, unchanged in keratinocytes treated with anti-integrin antibodies. Stimulation of 92 kDa enzyme was found to be caused directly by antibody binding to integrins, since Fab-fragments of anti-beta1 antibodies alone were able to induce collagenase expression in the absence of secondary, clustering antibodies. Antibodies against alpha2beta1 integrin caused no stimulation. Keratinocytes seeded on different substrata (plastic, collagen, fibronectin, laminin, or vitronectin) showed equal induction of type IV collagenase expression. Expression of 92 kDa type IV collagenase could not be induced by peptides (GRGDS, GRGES), proteins (fibronectin, laminin, fibrinogen, albumin), or antibodies to fibronectin. We suggest that proteolytic processes around keratinocytes can be regulated by extracellular factors signalling through integrin-type receptors. (C) 1993 Wiley-Liss, Inc.

Children with posterior fossa abnormalities had lower mean initial and follow-up developmental quotients compared to those with normal imaging or supratentorial abnormalities alone. Age of onset of infantile spasms, latency to treatment, response to steroids, and follow-up EEG pattern were not significantly different among the three groups. Six children (6%) had Dandy-Walker cysts, an association rarely reported with infantile spasms. We conclude that the presence of posterior fossa abnormalities in patients with infantile spasms portends a relatively poor developmental outcome.

In this study, we have evaluated the potential role of the insulin-like growth factors (IGFs) on the growth of MCF-7 mammary tumor cells and the effect of LHRH analogs on IGF action. The mitogenic effects of IGF-I, IGF-II, and insulin were compared. IGF-I was found to be 3 times more potent than IGF-II and 30 times more potent than insulin, suggesting that the effects of these growth factors are mediated by the IGF-I receptor. IGFs released by MCF-7 cells were measured by specific RIA after acid extraction and chromatography, so as to avoid the interference of IGF-binding proteins. MCF-7 cells secreted IGF-II, but not IGF-1. Estradiol (10(-9) mol/L) stimulated IGF-II release; this release preceded the effect of estradiol on cell growth. The LHRH antagonist [Ac-D-Nal(2)1,D-Phe(4Cl)2,D-Pal(3)3,D-Cit6,D-Ala10]LHRH (SB-75, CETRORELIX) inhbited basal, estrogen-induced, and IGF-induced growth. Moreover, this antagonist almost completely inhibited IGF-II release from MCF-7 cells. This effect preceeded the inhibition of tumor cell growth. We conclude that a LHRH antagonist can inhibit the growth of breast tumors by interfering with the autocrine action of IGF-II and by directly inhibiting the growth stimulatory effect of IGFs.

To assess the metabolism of HDL apolipoproteins in CETP deficiency, in vivo apolipoprotein kinetic studies were performed using endogenous and exogenous labeling techniques in two unrelated homozygotes with CETP deficiency, one heterozygote, and four control subjects. All study subjects were administered C-13(6)-labeled phenylalanine by primed constant infusion for up to 16 h. The fractional synthetic rates (FSRs) of apoA-I in two homozygotes with CETP deficiency (0.135, 0.134/d) were found to be significantly lower than those in controls (0.196+/-0.041/d, P < 0.01). Delayed apoA-I catabolism was confirmed by an exogenous radiotracer study in one CETP-deficient homozygote, in whom the fractional catabolic rate of I-125-apoA-I was 0.139/d (normal 0.216+/-0.018/d). The FSRs of apoA-II were also significantly lower in the homozygous CETP-deficient subjects (0.104, 0.112/d) than in the controls (0.170+/-0.023/d, P < 0.01). The production rates of apoA-land apoA-II were normal in both homozygous CETP-deficient subjects. The turnover of apoA-I and apoA-II was substantially slower in both HDL, and HDL3 in the CETP-deficient homozygotes than in controls. The kinetics of apoA-I and apoA-II in the CETP-deficient heterozygote were not different from those in controls. These data establish that homozygous CETP deficiency causes markedly delayed catabolism of apoA-I and apoA-II without affecting the production rates of these apolipoproteins.

MF patients have impaired filarial antigen (Ag)-specific lymphocyte proliferation and decreased frequencies (Fo) of Ag-specific T cells, and yet elevated serum IgE and antifilarial IgG4. To investigate the mechanism of Ag-specific anergy in MF patients in contrast to amicrofilaremic individuals with chronic lymphatic obstruction (CP), the Fo of Ag-specific lymphocytes from peripheral blood mononuclear cells secreting either IL-4 or IFN-gamma were assessed by filter spot enzyme-linked immunosorbent assay, and IL-10 and transforming growth factor-beta (TGF-beta) mRNA transcript levels were assessed by a semiquantitative reverse transcriptase polymerase chain reaction technique. The Fo of filaria-specific IL-4-secreting lymphocytes were equivalent in both MF (geometric mean [GM] = 1:11,700) and CP (GM = 1:29,300 P = 0.08), whereas the Fo of IFN-gamma-secreting lymphocytes were lower in MF (GM 1:39,300) than in CP (GM = 1:4,200, P < 0.01). When the ratio of IL4/IFN-gamma (T helper type 2 [Th2]/Th1)-secreting cells was examined, MF subjects showed a predominant Th2 response (8:1) compared with a Th1 response in CP individuals (1:4). mRNA transcript levels of IL-10 were also significantly elevated in MF compared with CP individuals (P < 0.01). Further, IL-10 and TGF-beta were shown to have a role in modulating the Ag-specific anergy among MF subjects, in that neutralizing anti-IL-10 or anti-TGF-beta significantly enhanced lymphocyte proliferation response (by 220-1,300%) to filarial Ags in MF individuals. These findings demonstrate that MF subjects respond to parasite antigen by producing a set of suppressive cytokines that may facilitate persistence of the parasite within humans while producing little clinical disease.

We, therefore, measured fasting muscle sympathetic nerve activity (MSNA) in the peroneal nerve and its relationship with energy expenditure and body composition in 25 relatively lean Pima Indian males (means+/-SD; 26+/-6 yr, 82+/-19 kg, 28+/-10% body fat) and 19 Caucasian males (29+/-5 yr, 81+/-13 kg, 24+/-9% body fat). 24-h energy expenditure, sleeping metabolic rate, and resting metabolic rate were measured in a respiratory chamber, whereas body composition was estimated by hydrodensitometry. Pima Indians had lower MSNA than Caucasians (23+/-6 vs 33+/-10 bursts/min, P = 0.0007). MSNA was significantly related to percent body fat in Caucasians (r = 0.55, P = 0.01) but not in Pimas. MSNA also correlated with energy expenditure adjusted for fat-free mass, fat mass, and age in Caucasians (r = 0.51, P = 0.03; r = 0.54, P = 0.02; and r = 0.53, P = 0.02 for adjusted 24-h energy expenditure, sleeping metabolic rate, and resting metabolic rate, respectively) but not in Pima Indians. In conclusion, the activity of the sympathetic nervous system is a determinant of energy expenditure in Caucasians. Individuals with low resting MSNA may be at risk for body weight gain resulting from a lower metabolic rate. A low resting MSNA and the lack of impact of MSNA on metabolic rate might play a role in the etiology of obesity in Pima Indians. C1 NIDDKD,CLIN DIABET & NUTR SECT,PHOENIX,AZ 85016.

At the time of maximal TGF-beta production, TGF-beta1 was localized by immunohistochemistry to be present almost exclusively in alveolar macrophages. In this study, we have demonstrated that alveolar macrophages stimulated by bleomycin-induced injury secrete large quantities of biologically active TGF-beta1 when explanted into tissue culture. However, alveolar macrophages from normal saline-treated rats secrete small quantities of biologically inactive TGF-beta. In contrast, splenic macrophages secrete large quantities of inactive TGF-beta and are unaffected by the intratracheal bleomycin treatment. High doses of the corticosteroid methylprednisolone given intramuscularly before and concomitantly with bleomycin administration prevented the influx of alveolar macrophages into the lungs, diminishing both the number of macrophages present in the alveoli and the total lung content of TGF-beta. However, the rate of secretion of TGF-beta by alveolar macrophages recovered from the alveoli was unchanged after corticosteroid treatment. When activated alveolar macrophages were cultured in the presence of several concentrations of dexamethasone that completely suppressed IL-1 secretion, little effect on TGF-secretion was observed. The findings in this study demonstrate that during bleomycin-induced injury, alveolar macrophages not only secrete large quantities of active TGF-beta1, but are a predominant source of the enhanced TGF-beta response seen in this model. Furthermore, the alveolar macrophage secretion of TGF-beta is not inhibited by the presence of high concentrations of corticosteroids. C1 NIH,CHEMOPREVENT LAB,BETHESDA,MD 20892.

Two overlapping segments of the 5' flanking region of the human (h) CRH gene, the proximal 0.9 kb (containing two perfect half-palindromic estrogen-responsive elements [EREs]) and the 2.4 kb (including the former and containing two additional perfect half-palindromic EREs), were examined for their ability to confer estrogen-mediated transcriptional enhancement to a homologous or heterologous promoter. The level of estrogen-induced transactivation by the 0.9- and 2.4-kb segments was determined by chloramphenicol acetyltransferase analysis in CV-1 cells cotransfected with estrogen receptor (ER) cDNA expression plasmids, and found to be respectively approximately 10% and 20% of that of the strongly estrogen-responsive Xenopus vitellogenin A2 enhancer. Gel retardation and immunoprecipitation demonstrated specific association between the perfect half-palindromic EREs of hCRH gene and the DNA binding domain of hER in vitro. These findings may constitute the basis of sexual dimorphism in the expression of the CRH gene in the central nervous system and periphery, and might shed light in existing gender differences in stress response and immune regulation.

It was found that rhIL-7 alone had no effect on the survival of the tumor-bearing recipients. However, the combination of rhIL-7 and human T cells significantly promoted the survival of the recipients compared with mice receiving either treatment by itself. When the surviving mice were analyzed 6 mo later for the degree of human cell engraftment, the recipients receiving both rhIL-7 and human T cells had greater numbers of human CD8+ T cells in the spleens. However, the human T cells recovered from the surviving mice showed low lytic activity against the tumor in vitro. Supernatants from human T cells cultured with the tumor and rhIL-7 in vitro were found to inhibit tumor growth and were demonstrated to contain high levels of IFN-gamma. Antibodies to IFN-gamma neutralized the growth inhibition of the tumor both in vitro and in vivo demonstrating that the in vivo mechanism underlying the antitumor effects of this regimen was partly dependent on the production of IFN-gamma by the T cells and not their cytolytic capability. Interestingly, systemic administration of rhIFN-gamma to tumor-bearing mice yielded little antitumor effect suggesting that adoptive immunotherapy with rhIL-7 was superior possibly because of the continuous local release of the cytokines. Therefore, rhIL-7 may be of clinical use as an antineoplastic agent and the human/mouse model is a potentially important preclinical model for in vivo evaluation of the efficacy of this and other immunotherapies.

We investigated the interaction of three h-TRbeta1 mutants representing different types of functional impairment (kindreds ED, OK, and PV) with different response elements for 3,3',5-triiodothyronine(T3)and with retinoid X receptor beta (RXPbeta). The mutant receptors showed an increased tendency to form homodimers on a palindromic T3-response element (TREpal), a direct repeat (DR + 4), and an inverted palindrome (TRElap). On TRElap, wild type TR binding was decreased by T3, while the mutant receptors showed a variably decreased degree of dissociation from TRElap in response to T3. The extent of dissociation was proportional to their T3 binding affinities. RXRbeta induced the formation of h-TRbeta1:RXRbeta heterodimers equally well for mutants and the wild type h-TRbeta1 on these T3 response elements. However, the T3-dependent increase in heterodimerization with RXRbeta was absent or reduced for the mutant TRs. Transient transfection studies indicated that the dominant negative potency was several-fold more pronounced on the TRElap as compared to TREpal or DR + 4. In CV-1 and HeLa cells, transfection of RXRbeta could not reverse the dominant negative action. These results demonstrate that the binding of mutant h-TRs to DNA, as well as their dominant negative potency, are TRE dependent. In addition, competition for DNA binding, rather than for limiting amounts of RXRbeta, is likely to mediate the dominant negative action.

In contrast to the Lyme disease spirochetes, which carry the ospC gene on a 26-kb circular plasmid, we mapped the gene in other Borrelia species to linear plasmids which varied in size among the isolates tested. Some isolates carry multiple copies of the gene residing on linear plasmids of different sizes. The analyses conducted here also demonstrate that these Borrelia species contain a linear chromosome. Northern (RNA) blot analyses demonstrated that the gene is transcriptionally expressed in all species examined. High levels of transcriptional expression were observed in some B. hermsii isolates. Transcriptional start site analyses revealed that the length of the untranslated leader sequence was identical to that observed in the Lyme disease spirochete species. By Western blotting (immunoblotting) with antiserum (polyclonal) raised against the OspC protein of B. burgdorferi, we detected an immunoreactive protein of the same molecular weight as the OspC found in Lyme disease spirochete species. The results presented here demonstrate the presence of a protein that is genetically and antigenically related to OspC which is expressed in all species of the genus Borrelia tested.

Treatments were administered to a total of 127 patients 1 hour before oral surgery. Analgesia was assessed every 30 minutes for 240 minutes after surgery. Analgesic efficacy was compared using the following standard pain intensity scales: visual analog scale, category, graphic rating, and global evaluation. Ibuprofen was significantly better than all other treatments for all measures of analgesic activity. The effects of terfenadine and ranitidine were similar to placebo. These data indicate that pretreatments with a single dose of a histamine receptor antagonist specific for either the H-1- or H-2-receptor does not produce analgesia in an oral surgery model of acute pain with overall assay sensitivity, suggesting that antihistamines that act primarily at peripheral sites are devoid of analgesic activity. These data contrast with other studies that have demonstrated analgesia using centrally acting antihistamines such as hydroxyzine, phenyltoloxamine, or orphenadrine.

Overall, there was a 28% decrease in the proportion of tooth surfaces attacked by caries for the primary dentition between the two surveys. The decrease for primary incisors was numerically small (5 surfaces per thousand surfaces at risk) and not statistically significant, whereas decreases in the canines and primary molars were considerably larger (23 surfaces per thousand) and statistically significant. For the permanent dentition, the overall decrease in the proportion of surfaces attacked was 35% during the 1979-87 period. Differences between the two surveys in the proportions of surfaces with caries were largest for pit and fissure surfaces (56 surfaces per thousand), followed by those for posterior approximal surfaces (14 surfaces per thousand) and all other smooth surfaces (5 surfaces per thousand). Almost all of these differences were statistically significant, except for some surfaces which experienced very few caries. C1 NIDR,EPIDEMIOL & ORAL DIS PREVENT PROGRAM,BETHESDA,MD 20892.

To determine whether this also occurs in the intact heart, we studied the effect of cumene hydroperoxide, an agent capable of initiating lipid peroxidation, on the ultrastructure and lanthanum (La) staining of isolated rat hearts perfused with HEPES buffer (pH 7.4) containing: 140mM NaCl, 5mM KCl, 1mM MgCl2, 3 mM HEPES, 1.5mM CaCl2 and 11mM glucose. No ultrastructural alterations or intracellular deposits of La were observed in myocytes of rats perfused with HEPES buffer. Perfusion with cumene hydroperoxide (0.5mM) for 30 min induced a release of malondialdehyde-like substance in the perfusate and a spectrum of myocardial ultrastructural alterations. La was always observed only outside the sarcolemma in myocytes with moderate damage consisting of clearing of the mitochondrial matrix and slight margination of chromatin in the nuclei. Intracellular La was found in myocytes with severe and irreversible damages consisting of fragmentation of cristae and electron-dense amorphous particles in mitochondria. La was deposited on the outer surface of the mitochondrial membranes, lipid droplets and myofilaments. These data suggest that mitochondria are more susceptible than is the sarcolemma to lipid peroxidation induced by cumene hydroperoxide in the beating rat heart.

Affinity chromatography revealed that bovine prolactin and human GH each bound to the same mammary gland proteins, yielding fractions enriched in binding activity and a protein of M(r) 36 000, assumed to be a bovine prolactin receptor. Affinity cross-linking of I-125-labelled human GH to mammary microsomes confirmed that the M(r) 36 000 protein was a bovine prolactin receptor. Binding assays of receptors in microsomes from the mammary tissue of cows and ewes at various stages of the lactational/reproductive cycle indicated developmental regulation of receptor concentration, but not receptor type, as no other bovine prolactin receptor type was detected by affinity cross-linking. These results suggest that differences in the response to prolactin in the mammary gland at various developmental stages in ruminants are not due to the expression of different forms of the prolactin receptor, and the lack of a prolactin effect on established lactation in ruminants is not due to the absence of the M(r) 36 000 form of the prolactin receptor.

We have made preparations of day 14/15 triple negative fetal thymocytes that exhibit the activated T lymphocyte markers CD25, intercellular adhesion molecule 1, Ly-6A/E, CD44, and heat stable antigen and are rapidly proliferating as evidenced by flow cytometric examination of BrdU incorporation. We found that binding activities of the gene regulators nuclear factor (NF)-kappaB, the NF-kappaB p50 homodimer complex, nuclear factor of activated T cells (NF-AT), oct-1, oct-2, activator protein 1 (AP-1), and serum response factor (SRF), are all present in these early thymocytes. Whereas the octamer factors and SRF persist during ontogeny, NF-kappaB, NF-AT, and AP-1 decrease and are undetectable in the adult thymus. Transfection of disaggregated thymocytes by electroporation or intact thymic lobes by gold-particle bombardment revealed that reporter constructs for NF-kappaB, NF-AT, AP-1, octamer factors and, to a small extent, the TCR-alpha enhancer were active in early thymocyte development. We rigorously eliminated the possibility that these transcriptional events were due to minor populations of TCR+ cells by showing that these reporter constructs were also active in recombinase activating gene (RAG)-/- thymocytes that are incapable of completing TCR gene rearrangement, and predominantly contain cells that have an activated phenotype. Thus, transcriptional events that are usually triggered by antigen stimulation in mature T cells take place early in thymic ontogeny in the absence of the TCR. Our analysis suggests that there are striking regulatory similarities but also important differences between the activation processes that take place in antigen-stimulated mature T cells and thymic progenitor cells.

Since the thymus is the primary organ in which T cells mature it is of interest to examine the effects of HIV infection in this tissue. HIV infection has been demonstrated in the thymuses of infected individuals and thymocytes have been previously demonstrated to be susceptible to HIV infection both in vivo, using the SCID-hu mouse, and in vitro. The present study sought to determine which subsets of thymocytes were infected in the SCID-hu mouse model and to evaluate HIV-related alterations in the thymic microenvironment. Using two different primary HIV isolates, infection was found in CD4+/CD8+ double positive thymocytes as well as in both the CD4+ and CD8+ single positive subsets of thymocytes. The kinetics of infection and resulting viral burden differed among the three thymocyte subsets and depended on which HIV isolate was used for infection. Thymic epithelial (TE) cells were also shown to endocytose virus and to often contain copious amounts of viral RNA in the cytoplasm by in situ hybridization, although productive infection of these cells could not be definitively shown. Furthermore, degenerating TE cells were observed even without detection of HIV in the degenerating cells. Two striking morphologic patterns of infection were seen, involving either predominantly thymocyte infection and depletion, or TE cell involvement with detectable cytoplasmic viral RNA and/or TE cell toxicity. Thus, a variety of cells in the human thymus is susceptible to HIV infection, and infection with HIV results in a marked disruption of the thymic microenvironment leading to depletion of thymocytes and degeneration of TE cells.

Structural analyses of the from cell lines with diverse pathogenic effects provided no clear correlation with lethality. The rabbit lines were provisionally designated T cells because they express interleukin 2R (IL-2R) and CD5 and lack surface immunoglobulin, but none express functional T cell receptor (TCR) alpha or beta transcripts. A more detailed characterization of the HTLV-I-infected cells was required to determine cell lineage and its potential influence on pathogenic consequences. Probes for rabbit TCRgamma and delta genes were derived and used to detect gamma and delta TCR RNA transcripts, identifying the in vitro transformed lines as gamma/delta T cells. CD4+ and CD8+ lines were derived from PBMC of HTLV-1-infected rabbits and CD4+ TCR-alpha/beta HTLV-I lines were derived from rabbit thymus, eliminating the possibility that the HTLV-I isolates used here transform only CD4-CD8- TCR-gamma/delta cells. The percentage of gamma/delta cells in rabbit PBMC is relatively high (23% in adult rabbits); this with diminution of CD4+ and CD8+ cells in IL-2-supplemented PBMC or thymocyte cultures may account for selection of rabbit HTLV-I-infected gamma/delta T cell lines in vitro. The availability of well-characterized T cell lines with diverse in vivo effects in the rabbit HTLV-I disease model allows evaluation of roles played by cell type in HTLV-I-mediated disease.

In stable hybridomas and myelomas expressing a ''switched'' (S) isotype, DNA deletions between Smu and a ''downstream' S region (S region recombination) have been found. In primary B cells, studies of the molecular basis of switching have been limited by the ability to sensitively quantitate the amount of DNA deletion; such studies would be of interest because other nondeletional mechanisms (trans-splicing, alternative processing of a long transcript) have been proposed to account for isotype switching in certain circumstances. We have applied the digestion-circularization polymerase chain reaction (DC-PCR) technique to measure the amount of S region recombination that occurs in the course of class switching in primary B lymphocytes. Resting B cells were cultured in lipopolysaccharide (LPS) and interleukin 4 (IL-4) to stimulate switching to IgG1. These cells begin to express membrane IgG1 at day 2.5 of culture and reach maximum expression by day 4.5. DNA was prepared from cultured cells and analyzed for Smu-Sgamma1 rearrangement by DC-PCR. Chimeric switch regions, indicating Smu-Sgamma1 recombination, were detected in amounts that, in most cases, correlated with surface expression. Furthermore, when cells were sorted on the basis of surface IgG1 expression, a mean of at least one Smu-Sgamma1 rearrangement per cell was seen in five out of seven experiments. In general, the IgG1+ cells obtained at 4.5 and 5.5 d of culture had close to 2 Smu-Sgamma1 rearrangements per cell. In IgG1- cells, Smu-Sgamma1 rearrangements were detectable, but at frequencies substantially lower that in IgG1+ cells. Thus, these results indicate that DNA deletion accompanies class switching in normal B cells stimulated with LPS and IL-4. C1 NIAID,IMMUNOL LAB,BETHESDA,MD 20892.

To determine the relationship between the superantigenic property of milk-borne MMTV and its in vivo infectivity, mice which were either positive or negative for expression of a transgene-encoded EalphaEbeta class II major histocompatibility complex (MHC) product were exposed to milk borne C3H MMTV. Superantigen-mediated deletion of Vbeta14-expressing T cells occurred only in Ealpha transgene-positive mice, indicating that the deletion was EalphaEbeta dependent. When mice were analyzed for viral infection by assaying viral p28 in the milk of recipient females, significant p28 levels were found only in EalphaEbeta transgene-positive mice. Similarly, the presence of C3H MMTV LTR mRNA in mammary glands, as detected by PCR, paralleled p28 levels. These findings indicate that Ealpha expression or the Ealpha-dependent T cell response to viral superantigen is causally related to susceptibility to MMTV infection, and that lack of a permissive class II product can protect mice from virus infection.

We have compared the sizes of the linear plasmid that carries the genes encoding the major outer-surface proteins OspA and OspB as well as the size and structure of the chromosome among the Lyme disease spirochaetes. We have found differences in the sizes of the ospA-containing plasmids, but not the linear chromosomes among the three species. The ospA-containing plasmid size of 50 kb in B. burgdorferi isolates is significantly smaller than the size of 55 kb in B. garinii isolates and 56 kb in group VS461 isolates.

NaK-ATPase-containing microsomes prepared from the electric organ of Electrophorus electricus were adsorbed to planar lipid bilayers for investigation of charge translocation, while rapid acid quenching was used to study the concomitant enzymatic partial reactions involved in phosphoenzyme formation. To facilitate comparison of these data, conditions were standardized with respect to pH (6.2), ionic composition, and temperature (24-degrees-C). The different phases of the current generated by the enzyme are analyzed under various conditions and compared with the kinetics of phosphoenzyme formation. The slowest time constant (tau3(-1) almost-equal-to 8 s-1) is related to the influence of the capacitive coupling of the adsorbed membrane fragments on the electrical signal. The relaxation time associated with the decaying phase of the electrical signal (tau2(-1) = 10-70 s-1) depends on ATP and caged ATP concentration. It is assigned to the ATP and caged ATP binding and exchange reaction. A kinetic model is proposed that explains the behavior of the relaxation time at different ATP and caged ATP concentrations. Control measurements with the rapid mixing technique confirm this assignment. The rising phase of the electrical signal was analyzed with a kinetic model based on a condensed Albers-Post cycle. Together with kinetic information obtained from rapid mixing studies, the analysis suggests that electroneutral ATP release, ATP and caged ATP binding, and exchange and phosphorylation are followed by a fast electrogenic E1P --> E2P transition. At 24-degrees-C and pH 6.2, the rate constant for the E1P --> E2P transition in NaK-ATPase from eel electric organ is greater-than-or-equal-to 1,000 s-1. C1 NIA,BALTIMORE,MD 21224.

Any time an opportunity arises to examine a problem from a different perspective, chances increase that new light will be shed on the problem. For example, while suicide is greatest in older Americans compared with any other US population group, it is less frequent in older blacks than older whites. Why? Among the different theories that have been advanced, one holds that older African Americans in reaching later life have surmounted more threats to self-esteem (compared with whites) and are thereby better adapted to new challenges associate with aging.1 Still, the discrepancy in suicide rates between older blacks and whites remains an important research question. In studying suicide with attention to racial and ethnic variables, the opportunity presents itself to gain a more fundamental understanding of suicide itself-to the benefit of all older adults, indeed to the benefit of all age groups. This paper focuses on some African American issues pertinent to geriatric psychiatry and identifies areas for further research. In addition to a selected literature review, the author draws on his own research from a 20-year longitudinal study, initiated in 1971, of a senior citizens' apartment building in Washington, DC, with a predominantly African American population.2 (1 = Group for the Advancement of Psychiatry, Committee on Cultural Psychiatry: Suicide and Ethnicity in the United States, New York, Bruner/Mazel, 1989; and 2 = Cohen GD: Lessons from longitudinal studies of mentally ill and mentally healthy elderly: A 17-year perspective, in Bergener M, Finkel SI (eds): Clinical and Scientific Psychogeriatrics, Vol. 1.

Starting with racemic cyclopentenylamine (10), the heterocyclic moieties of the clitocine analogue 4 and related 1,6-dihydro-6-oxo, 5, and 2-amino-1,6-dihydro-6-oxo, 6, analogues were constructed. These compounds were respectively converted to 8-aza-neplanocin A (7), 8-aza-neplanocin D (8, the inosine analogue), and the corresponding 8-aza-guanosine analogue 9 after reduction of the nitro group followed by nitrous acid cyclization. Extensive antiviral evaluation revealed that only 8-aza-neplanocin A (7) had enough antiviral activity to warrant further studies. This compound showed weak antiviral activity against HSV-1, HSV-2, and the thymidine kinase deficient (TK-) HSV-1. However, it displayed good antiviral activity against human cytomegalovirus (HCMV) at a concentration of 0.40-2.50 mu g/lml, well below the cytotoxicity threshold. This activity profile is consistent with a mechanism of action involving the inhibition of the enzyme adenosylhomo-cysteine hydrolase. C1 KATHOLIEKE UNIV LEUVEN,REGA INST,B-3000 LOUVAIN,BELGIUM.

Multidrug-resistant cultured cells, in which the accumulation of daunomycin can be reversibly controlled with verapamil to block the multidrug transporter, were incubated in daunomycin and verapamil and the accumulated daunomycin was visualized with epifluorescence optics. After fixation under a variety of different conditions to make cells permeable to diaminobenzidine (DAB), the internal daunomycin was illuminated under the fluorescence microscope in the presence of DAB. Photooxidation of DAB in sites of fluorescing daunomycin (photoconversion) resulted in intracellular deposition of oxidized DAB product. These sites were then visualized by transmission electron microscopy. In cells in which the multidrug transporter was inhibited by verapamil, daunomycin was localized in the nucleus of cells by mild fixation conditions such as formaldehyde. Increasing amounts of glutaraldehyde in the fixative caused apparent quenching of the nuclear fluorescence but still allowed fluorescence to occur in other cell organelles, which were then well preserved. Daunomycin was found in the nuclear envelope, the endoplasmic reticulum, and in lysosomes in cells in which the multidrug transporter was inhibited. Lysosomal accumulation has been previously described and was expected because of the known accumulation of positively charged molecules in organelles with low pH. However, the accumulation of daunomycin in the nuclear envelope and endoplasmic reticulum has not been previously observed. These results dearly demonstrate the utility of fluorescence photoconversion methodology for the high-resolution ultrastructural localization of fluorescent materials.

Constant region of gamma-globulin (Cgamma) subclass germ-line transcripts were measured using newly developed reverse transcription and polymerase chain reaction (RT-PCR) assays that were shown to be Cgamma subclass-specific germ-line transcripts by size of the amplification products obtained before and after digestion with appropriate endonucleases (NarI and NcoI). In initial studies we found that Cgamma1 and Cgamma2 germ-line transcripts were constitutively expressed in total peripheral blood B cells, but not in high density sIgM+(sIgG-) B cells prepared with Percoll density gradients and magnetic beads separation techniques; the latter cells were therefore used throughout this study. Induction of germ-line transcripts (germ-line Cgamma1 transcript) was noted in stimulated B cells (SAC plus IL-2) at 6 h; thus, the appearance of germ-line transcripts could not be attributed to preferential growth of B cells expressing germ-line transcripts. In subsequent studies we found that induction of germ-line transcripts for the various IgG subclasses fell into two patterns. Induction of Cgamma3 and Cgamma1 germ-line transcripts, transcripts of genes in the first human duplication unit, generally required a proliferative stimulus (Staphylococcus aureus Cowan I, SAC) and was brought about by SAC plus IL-4 (Cgamma3 germ-line transcripts) and SAC alone or SAC plus IL-2 (Cgamma1 germ-line transcripts); in contrast, induction of Cgamma2 and Cgamma4 germ-line transcripts, transcripts of genes in the second duplication unit, was accomplished with cytokines alone: IFN-gamma (Cgamma2 germ-line transcripts) and IL-4 (Cgamma4 germ-line transcripts), and was not augmented by addition of a proliferative stimulus. Finally, we found that IFN-gamma inhibited IL-4-induced Cgamma3 and Cgamma4 germ-line transcripts (with or without SAC). These findings establish that the various human IgG subclasses manifest distinct requirements for the regulation of early steps in isotype differentiation. In addition, they suggest that human Cgamma genes exhibit patterns of regulation related to their respective duplication units.

Moreover, when injected at 4 wk after infection with anti-IFN-gamma mAb, progression of toxoplasmic encephalitis is markedly accelerated, resulting in death of the animals by 9 to 12 days posttreatment. In this study, we investigated the expression of mRNAs encoding cytokines as well as lymphocyte and macrophage markers during the development of toxoplasmic encephalitis. High levels of lymphocyte CD4 and CD8 surface Ag transcript were detected in the brains of mice throughout the infection. In addition from 2 to 4 wk we found elevations of Th1 (IFN-gamma and IL-2) but not of Th2 (IL-4 and IL-5) cytokine mRNAs. The elevation in Th1 cytokines was accompanied by increases in the expression of monokine (IL-1, IL-6, IL-10, granulocyte macrophage-colony stimulating factor [GM-CSF], and TNF-alpha) mRNAs, as well as markers expressed by activated macrophages (major histocmpatibility class II [Ia], inducible nitric oxide synthase [iNOS] and macrophage activation gene 1 [Mag-1]). Interestingly, after 8 wk of infection with T. gondii we observed a dramatic decrease of Th1 cytokine and most monokine (IL-1, IL-6, GM-CSF, and TNF-alpha) as well as Mag-1 and iNOS mRNA levels. This down-regulation was associated with enhanced necrosis and neutrophilic infiltrates in the brain accompanied by increased expression of genes expressed specifically by the tachyzoite stage of T. gondii (T. gondii surface antigen 1 [SAG-1] and T. gondii surface antigen 2 [SAG-2]). Similarly, in mice chronically infected with T gondii and treated with anti-IFN-gamma mAb the resulting pathology was associated with decreased expression of TNF-alpha and iNOS and increased expression of SAG-1 and SAG-2. Moreover, treatment with anti-TNF-alpha mAb also resulted in enhanced pathology, which correlated with low levels of iNOS mRNA and high levels of tachyzoite-specific mRNAs. Together these results suggest that reactivation of T. gondii results from a down-regulation of IFN-gamma and TNF-alpha expression leading to decreased macrophage or microglial cell activation, release of parasite growth, and subsequent tissue damage.

To determine whether parasite-derived Ag preferentially expand a Th2-like cell population, a filter immunoplaque assay was used to enumerate the frequencies (F0) of PBMC and CD4+-enriched PBMC from individuals with helminth infections secreting selected cytokines in response to parasite-derived (PAg) and nonparasite antigens (NPAg). In 20 individuals with lymphatic filariasis, frequency analysis of PBMC secreting IL-4 and IFN-gamma indicated that the F0 of PAg-specific IL-4-secreting cel Is (geometric mean F0 (GM): 1/12,100) was 57-fold higher than the corresponding F0 of NPAg-reactive cells (GM: 1/692,000; p < 0.02). In marked contrast, the F0 of IFN-gamma-secreting cells responding to PAg (GM: 1/2,700) did not differ from those of cells specific for NPAg (GM: 1/3,400; p = 0.83). In another group of helminth-infected individuals, the F0 of highly enriched CD4+ cells secreting IL-4 and IL-5 in response to PAg (GMs: 1/2,600 and 1/5,600 CD4+ cells, respectively) were also found to be significantly higher than those specific for NPAg (GMs: 1/291,000 and 1/303,000 CD4+; p < 0.05 and p < 0.01, respectively), whereas the corresponding F0 of IFN-gamma- and granulocyte-macrophage-CSF-secreting cells were equivalent for PAg and NPag. Furthermore, the proportion of PAg-specific IL-4- and IL-5-secreting CD4+ cells relative to all cells secreting the given cytokine were approximately 29-fold higher than the proportion of NPAg-specific cells secreting these cytokines. Again, the corresponding proportions of Ag-specific IFN-gamma and GM-CSF-secreting CD4+ cells were equivalent for PAg and NPAg. Thus, in this ex vivo system, a circulating population of IL-4- and IL-5-secreting (Th2-like) cells has been shown to exist in humans; PAg appears to expand these cells preferentially.

Little is known, however, how these two processes are negatively regulated and thus, how mast cell number is controlled in normal or pathologic processes. In this study we hypothesized that IL-3-dependent mast cells would undergo programmed cell death (apoptosis) on removal of IL-3 as was shown with other growth factor-dependent hemopoietic cells. Apoptotic changes were analyzed using light microscopy, fluorescent staining with acridine orange, flow cytometric analysis, and DNA electrophoresis. We could demonstrate that elimination of IL-3 from either primary bone marrow-derived cultured mast cell cultures (BMCMC) or from the growth factor-dependent mast cell line MCP5 resulted in the characteristic changes of apoptosis including condensed chromatin, fragmented nuclei, cellular vacuolization, typical pattern of propidium iodide or Hoechst 33342 uptake by flow cytometry, and the characteristic 200 bp ''ladder'' pattern of DNA cleavage. These events were prevented by SCF, an action that was in part mediated by tyrosine kinases, in that the tyrosine kinase inhibitor herbimycin inhibited the action of SCF in preventing apoptosis in IL-3-deprived cells. By using anti c-kit mAb and IL-3-dependent BMCMC obtained from W/W(v) mice homozygous for mutation at the w locus that encodes the c-kit receptor, we could also show that SCF exerted its effect via c-kit. Neither dexamethasone nor cyclosporin A inhibited the ''rescue'' effect of SCF, suggesting that ''rescue'' was mediated by SCF and not through the induction of other cytokines. Thus, IL-3-dependent mast cells undergo apoptosis on removal of IL-3, an event that is prevented by the addition of SCF through its ligand c-kit, thus demonstrating how these principle mast cell growth factors may act in concert to regulate mast cell number under physiologic conditions.

We identified the minimal amino acid residues within the epitopes required for binding and recognition by HLA-A2- and B14-restricted CTL, identified the critical residues within the peptide sequence defining the HLA-A2-restricted response, and demonstrated that CTL can lyse T cells infected with HTLV-1. This study shows that the CTL response to HTLV-1 tax in patients with neurologic diseases is heterogenous in nature and is not confined to patients of a single HLA haplotype or to a specific region of the tax protein.

SLE patients (n = 26) and controls (n = 8) were categorized as responder (+) or nonresponder (-) for each stimulus and grouped according to their paired response pattern. All controls responded to both influenza virus (Flu) or alloantigen (Allo) and were categorized as +/+. In contrast, SLE patient response patterns were heterogeneous with no evidence for a single SLE-associated defect. Instead, SLE patient responses fell into one of three different patterns: a) normal responses to both Flu and Allo (+/+), observed in nine (35%) patients; b) defective responses to Flu but intact Allo responses (-/+) observed in 12 (46%) SLE patients; and c) defective responses to both Flu and Allo (-/-), observed in five (19%) SLE patients. There was no statistically significant correlation between immune response pattern and the use of immunosuppressants. Further analysis of -/- SLE patients indicated defects in APC function and in both CD4+ and CD8+ T cell function. In contrast, cell depletion and add-back studies in -/+ SLE patients demonstrated defects in APC function only. Thus, similar to the well recognized clinical heterogeneity among SLE patients, our data support the concept that SLE patients are heterogeneous with respect to in vitro T cell-APC function, exhibiting responses ranging from normal function to defects in APC and in both T cell subsets. Prospective studies are in progress to determine the clinical relevance of these observations. C1 DEPT VET AFFAIRS,BALTIMORE,MD 21201. UNIFORMED SERV UNIV HLTH SCI,DEPT MED,BETHESDA,MD 20814.

Aspects of the molecular and cellular biology of major histocompatibility complex class I are reviewed. Evidence for histology-specific molecular mechanisms in the antigen-processing and -presentation deficiencies observed in some human and murine tumors is presented. Mechanisms identified include down-regulation of antigen processing, loss of functional beta2-microglobulin, and deletion of specific alpha-chain alleles. Finally, we discuss studies using an antigen-presentation-deficient mouse tumor as a model for the immunogenetherapy of an antigen-presentation deficiency. C1 NIAID,VIRAL DIS LAB,BETHESDA,MD 20892.

This has raised expectations that it will prove possible to achieve similar successes with human cancers. CD8+ T cells recognize peptides of 8-10 residues derived from cytosolic proteins that are bound to the class I molecules of the major histocompatibility complex. To most effectively manipulate the T-cell response to tumor cells, it is essential to understand the means by which the peptide-class I complex is created in cells. An overview of this process is provided with an emphasis toward the recent findings made by our laboratory. RP BENNINK, JR (reprint author), NIAID,VIRAL DIS LAB,BETHESDA,MD 20892, USA.

This difficulty is not limited to tumor antigen, since similar problems are encountered growing CD4+ T cells that recognize alloantigen, tetanus, or candida. Four basic findings are reviewed in this article, stemming from work with identical results in both human and mouse. (a) Although CD4+ T cells initially proliferate after exposure to appropriate antigen-presenting cells (APCs), such proliferation is not sustained; however, expansion of CD4- T cells can be achieved with the addition of recombinant interleukin-2 (rIL2) or rIL-7. (b) Specific CD4+ responses to antigens are often better sustained with exogenous IL-7 than with exogenous IL-2. (c) Adding rIL-7 or rIL-2 permits sustained CD4+ T-cell proliferation, but subsequent culture restimulation is complicated by high background reactivity to APCs whether APCs are antigen pulsed or not; this problem can be overcome by addition of exogenous interferon-gamma (IFN-gamma) to the CD4+ cultures. (d) In certain instances proliferation is paradoxically impaired by reexposure to specific antigen, possibly reflecting apoptosis; this problem is also overcome by addition of rINF-gamma to culture. We conclude that combinations of exogenous IL-7, IL-2, and IFN-gamma with APC restimulation can be used to sustain antigen-specific CD4+ T cells in culture. Using these techniques, antitumor CD4+ T cells were propagated from the peripheral blood of two tumor-bearing patients. C1 NIH,DIV CANC BIOL & DIAG,EXPTL IMMUNOL BRANCH,BETHESDA,MD 20892.

The mean entry CD4 cell count was 184/mm3. Patients received 3-week cycles consisting of zidovudine plus acyclovir, dideoxyinosine, and dideoxycytidine for 1 week each. Overall, the regimen was well tolerated for up to 3 years. The principal toxicities were anemia, nausea, and vomiting; 1 patient developed retinal lesions. The mean CD4 cell count reached a peak of 64 cells/mm3 above baseline at week 8 (P = .005 compared to baseline) and remained above baseline for >40 weeks. Patients also gained weight and had decreases in serum HIV p24 antigen. Eight patients developed opportunistic infections or tumors. Only 4 patients died during 3 years of follow-up. This regimen appears to be generally tolerable and to have anti-HIV activity. Additional studies will be needed, however, to learn how to best combine the available agents in patients with HIV infection. C1 NCI,MED BRANCH,BIOSTAT & DATA MANAGEMENT SECT,BETHESDA,MD 20892.

These proteins were detected within 60 min after the addition of the bacteria to the epithelial cell cultures, and their synthesis was temporally associated with an increase in C jejuni internalization. A rabbit antiserum raised against bacteria that were cultivated with INT 407 cells recognized nine proteins that were not recognized by an antiserum against C jejuni cultivated in medium alone. The former antiserum inhibited the internalization, but not the binding, of Campylobacter jejuni in a dose-dependent fashion. The results suggest that one or more of the proteins synthesized by C jejuni in response to cocultivation with epithelial cells plays a role in facilitating internalization.

Patients' peripheral blood leukocytes (PBL) were tested before, during, and after therapy with rCD4-IgG for T helper (TH) cell function assessed by antigen- and mitogen-stimulated proliferation and interleukin-2 production in response to influenza A virus, allogeneic PBL (alloantigens), and phytohemagglutinin. Although clinical benefit was not evident, rCD4-IgG treatment was associated with rapid and potent improved TH cell function for two of three stimuli tested in 90% of the patients. These data are complemented by an in vitro experimental model that demonstrates the opposing immunologic effects of rgp120 and rCD4-IgG on TH cell function of PBL from uninfected individuals. Thus, restoration of TH cell function by rCD4-IgG in the absence of increased CD4 cell counts could be due to removal of an immunosuppressive factor, possibly gp 1 20. These findings suggest that rCD4-IgG can induce partial restoration of immune function in AIDS patients, even in the absence of apparent short-term clinical benefit.

Transmission electron microscopy performed on the son's platelets demonstrated an unusual arrangement of membrane complexes formed by association of the open canalicular and dense tubular systems. Number and appearance of platelet alpha-granules, dense bodies, and mitochondria were normal. These platelets demonstrated normal agonist-induced Ca2+ flux in response to collagen and supranormal responses to arachidonic acid but displayed no increase in intracellular free Ca2+ in response to thrombin. Platelet surface glycoproteins IIb-IIIa, Ib, and granular membrane protein-140 measured by flourescence-activated flow cytometry, along with platelet content of von Willebrand factor and fibrinogen, were normal. The von Willebrand factor binding function of GP-Ib on these platelets was also normal. We believe that this family demonstrates a unique macrothrombocytopenia syndrome characterized by deficient Ca2+ mobilization in response to thrombin that is not related to a defect in GP-Ib.

We developed antibodies to human MSP for detection in Western blots, quantification in biological fluids, and neutralization of activity. Immunogens included native MSP, reduced and alkylated alpha and beta chains, and peptides of MSP regions with minimal sequence similarity to other kringle proteins. We found three antibody categories based on interaction with the following types of epitope: primary sequence, discontinuous (dependent on disulfide bonds), and cryptic (not exposed in native MSP). None of the antibodies reacted with related kringle proteins. A specific sandwich ELISA was developed for measuring human MSP. The mean serum concentration was 4 nM. Serum MSP did not increase over a 24-h period in response to intravenous lipopolysaccharide, indicating that MSP is not an acute phase protein. These findings are consistent with the hypothesis that regulation of MSP activity is by conversion of pro-MSP to MSP rather than by rapid changes in rates of synthesis.

After reverse transcription of the region from exons 10 to 13 to cDNA, fragments of the expected size were amplified from all heterozygous and normal subjects. In three subjects an additional alternatively spliced product was observed, which was found to contain a termination codon. In repeated experiments it was not possible to detect any CFTR mRNA in cells derived from the R553X homozygous patient. Furthermore, in subjects heterozygous for R553X we could not detect by hybridisation with a specific oligonucleotide probe and direct sequencing any CFTR mRNA derived from the R553X allele. However, the wild type product was present in all of these subjects. Our results support the view that nonsense mutations in the CFTR gene can lead to a reduction or absence of cytoplasmic CFTR mRNA.

A gene for Usher syndrome type II (USH2) has been localised to chromosome 1q32-q41. DNA from a family with four of seven sibs affected with clinical characteristics of Usher syndrome type II was genotyped using markers spanning the 1q32-1q41 region. These included D1S70 and D1S81, which are believed to flank USH2. Genotypic results and subsequent linkage analysis indicated non-linkage of this family to these markers. The A test analysis for heterogeneity with this family and 32 other Usher type II families was statistically significant at p<0.05. Further clinical evaluation of this family was done in light of the linkage results to determine if any phenotypic characteristics would allow for clinical identification of the unlinked type. No clear phenotypic differences were observed; however, this unlinked family may represent a previously unreported subtype of Usher type II characterised by a milder form of retinitis pigmentosa and mild vestibular abnormalities. Heterogeneity of Usher syndrome type II complicates efforts to isolate and clone Usher syndrome genes using linkage analysis and limits the use of DNA markers in early detection of Usher type II.

Since 1,2,4-oxadiazoles are excellent bioisosteres of ester groups, we have prepared several 3beta-(substituted phenyl)-2beta-(3-substituted 1',2',4'-oxadiazol-5'-yl)tropanes (5b-h) and all four stereoisomers of (1R,5S)-3 phenyl-2-(3-methyl-1',2',4'-oxadiazol-5'-yl)tropane (5a and 6-8). The 3alpha-phenyl-2alpha-(3'-methyl-1',2',4'-oxadiazole) isomer 7 was prepared from a stereoselective addition of phenyllithium to (1R,5S)-2-(3'-methyl-1',2',4'-oxadizol-5-yl)-8-methyl-8-azabicyclo[3.2.1]oct-2-ene(11). The binding affinities for 5a-h and 6-8 at the dopamine, serotonin, and norepinephrine transporters were obtained. In general these bioisosteres showed potencies for the dopamine transporter similar to those of their parent esters. 3beta-(4'-Chlorophenyl)-2beta-(3'-phenyl-1',2',4'-oxadiazol-5'-yl)tropane (5d) was the most potent analogue with an IC50 of 1.62 nM. However, 3beta-(4'-chlorophenyl)-2beta-(3'-methoxyphenyl-1',2',4'-oxadiazol-5'-yl)tropane (5e) with an IC50 of 1.81 nM was the most selective analogue for the dopamine transporter showing NE/DA and 5-HT/DA ratios of 461 and 186, respectively. The cis- and trans-3alpha-phenyl-2-(3'-methyl-1',2',4'-oxadiazol-5'-yl)tropanes (7 and 8), which exist in a boat conformation, have IC50 values only slightly greater than that of the 3beta,2beta-isomer (5a) which possesses the cocaine stereochemistry.

Amine 2 bears some structural resemblance to two other natural product PTK inhibitors, erbstatin (3) and piceatannol (4). Non-amine containing analogues of 2 were therefore synthesized which incorporated additional aspects of either erbstatin or piceatannol. Examination of these inhibitors in immunoprecipitated p56lck, epidermal growth factor receptor (EGFR), and c-erb B-2/HER 2/neu PTK preparations showed that compound 12 (IC50 = 60 nM) was one of the most potent p56lck inhibitors reported to date. These results demonstrate that nitrogen is not an essential component of the lavendustin A pharmacophore 2 and that 1,2-diarylethanes and -ethenes bearing a salicyl moiety appear to be valuable structural motifs for the construction of extremely potent PTK inhibitors.

Taking compound 7 and the isomeric 8 as lead structures, bicyclic nuclei 9-12 were prepared as conformationally constrained mimetics in which the hydroxyphenyl rings of 7 and 8 are held coplanar with the stilbene ethylene bridge. A similar approach with styryl-based PTK inhibitors of structure 1 previously yielded analogues 2 with enhanced potency. In the present case, however, the resulting salicyl-containing bicyclics exhibited extremely poor inhibitory potency when examined against autophosphorylation of immunoprecipitated p56lck PTK preparations. The implications of these results are discussed as they relate to the potential ways in which salicyl-containing stilbenes may be oriented relative to styryl-based inhibitors of type 1 and to an emerging class of potent aryl-substituted bicyclic inhibitors exemplified by compound 31.

Run-on assays using liver nuclei from GH-deficient Little mice indicated that the P450(15)alpha gene is transcriptionally repressed by GH in male mice. BALB/cJ is a variant strain in which the gene is expressed in the males as well as in the females. Genetic crosses between DBA/2J and BALB/cJ indicated that expression of the P450(15)alpha, gene in BALB/cJ males is inherited as a recessive trait and is regulated by a single locus. The parental origin of the P450(15)alpha genes, determined using restriction site polymorphism in the exons of the P450(15)alpha genes, divided the F2 males expressing the P450(15)alpha gene into three phenotypes at a ratio of 1:1:2, the individuals expressing the gene from only BALB/cJ or DBA/2J and the individuals expressing the genes from both parents respectively. The results indicate that the repression of the P450(15)alpha gene in male mice is regulated by a trans-acting regulatory locus between the DBA/2J and BALB/cJ pairs. Because hypophysectomy derepressed the P450(15)alpha gene in F1 males and GH repressed the gene in hypophysectomized F1 males, the hormone appears to regulate gene repression through a trans-acting locus, named GH-dependent repression, GDR.

Many of the new agents under consideration in the NCI program are either natural products or derivatives of natural product leads, and of critical importance to their development is the issue of drug supply. In responding to the drug supply crisis which emerged with the demonstration of the clinical efficacy of taxol, the NCI has identified several important lessons for those interested in natural product drug discovery and development. As a result, the NCI has developed plans to avert similar supply crises in the future by initiating exploratory research projects for large-scale production of promising agents at the earliest possible point following the demonstration of confirmed antitumor activity. These plans, together with a review of the development of taxol, are presented in this paper. C1 NCI,DIV CANC TREATMENT,DEV THERAPEUT PROGRAM,BETHESDA,MD 20892.

CELL-GROWTH INHIBITORY ISOCARBOSTYRILS FROM HYMENOCALLIS SO JOURNAL OF NATURAL PRODUCTS LA English DT Article ID LINES AB The bulbs of Hymenocallis littoralis, collected in Hawaii and horticulturally grown in Arizona, and bulbs of Hymenocallis caribaea and Hymenocallis latifolia, collected in Singapore, were found to contain a cytotoxic, isocarbostyril-type biosynthetic product, 7-deoxy-trans-dihydronarciclasine [2]. This new compound inhibited the cytopathicity and/or replication of various viruses. Companion cytotoxic constituents of H. littoralis and Hymenocallis sp. were found to be pancratistatin [1), narciclasine [5], and 7-deoxynarciclasine [4). These four compounds, along with four other closely related compounds, were comparatively evaluated in the National Cancer Institute's in vitro cytocoxicity panel. Although there were striking differences in overall potency, some of the compounds shared a highly characteristic differential cytotoxicity profile against the 60 diverse human rumor cell lines comprising the NCI panel. As a group, the melanoma subpanel lines were most sensitive; certain individual lines within other subpanels (eg., NSC lung, colon, brain, renal) were as much as a thousand-fold of more sensitive than the less sensitive lines.

Although the emergence of a 6-OHDA-like substance was reported in the striatum of methamphetamine-treated rats, this substance has not been identified by a direct approach. We used mass fragmentography to search for 6-OHDA in the rat frontal cortex and striatum after the administration of a number of drugs including 3,4-dihydroxyphenyl-L-alanine, methamphetamine, amphetamine, and cocaine, all of which increase synaptic dopamine. No 6-OHDA was detected after the acute systemic administration of these agents. Intraventricular administration of 6-OHDA (10 mug/rat) produced measurable concentrations of 6-OHDA that were higher in the striatum than in the frontal cortex. Intraventricular administration of 2,4,5-trihydroxyphenyl-D,L-alanine (6-OHDOPA; 10 mug/rat) produced similar concentrations of 6-OHDA in both regions. Pargyline, but not carbidopa (alpha-methyldopahydrazine), enhanced the effect of intraperitoneal 6-OHDOPA administration (80 mg/kg). We conclude that (1) 6-OHDOPA can cross the blood-brain barrier and is converted to 6-OHDA in the brain, (2) 6-OHDA is a substrate for monoamine oxidase(s) and therefore a search for its purported deaminated metabolite is warranted, and (3) acute treatment with the above stimulants either does not lead to the formation of 6-OHDA or produces concentrations below the detection limit of the assay (< 34 pg/mg of protein).

Immunoblotting revealed that in adrenal medulla both chains migrate very closely together in two-dimensional electrophoresis. Both chains with slightly differing molecular sizes are found in several endocrine tissues and in brain, kidney, liver, and serum. The mRNA has an analogous widespread distribution. In primary cultures of chromaffin cells the level of message becomes significantly increased by treatment with histamine or 12-O-tetradecanoylphorbol 13-acetate/forskolin. However, the increase is small when compared with that of secretogranin II. The subcellular localization of glycoprotein III in endocrine organs and in the posterior pituitary was investigated by subcellular fractionation and immunoelectron microscopy. Glycoprotein III was found to be confined to the large dense-core vesicles of these organs. For a discussion of the function of glycoprotein III, its localization in these organelles has to be taken into account.

This study examined the role of endogenous CRH in HPA and adrenomedullary responses to hypoglycemia in Sprague-Dawley rats, by using anti-CRH immune serum or a CRH antagonist (alpha-helical h/r CRH9-41, and in Lewis rats, a strain characterized by deficient hypothalamic CRH responses during stress. In conscious Sprague-Dawley rats with indwelling arterial and venous cannulas, insulin (0.3 U/kg) was injected iv, and responses of serum glucose concentrations and plasma levels of corticotropin (ACTH) and catechols (including epinephrine, EPI; norepinephrine, NE; dihydroxyphenylalanine, DOPA; dihydroxyphenylglycol, DHPG; and dihydroxyphenylacetic acid, DOPAC) were assessed, with or without pretreatment with anti-CRH immune serum (0.5 or 1.0 ml iv or 10 mul icv) or alpha-helical h/r CRH9-41, (130 nmol iv or 13 nmol icv). Responses to insulin (1.0 U/kg iv) were also measured in conscious juvenile Lewis and Fischer 344/N rats. Insulin-induced hypoglycemia markedly increased plasma levels of EPI and ACTH in all groups. Pretreatment iv with 1.0 ml of anti-CRH immune serum blocked the ACTH response to insulin but failed to attenuate the EPI response. Alpha-helical h/r CRH9-41, whether given iv or icv, failed to alter ACTH or EPI responses to insulin, although the antagonist did block EPI responses to icv CRH. Hypoglycemia elicited similar increments in ACTH levels in Lewis rats and Fischer 344/N control rats; and although Lewis rats had lower baseline EPI and smaller responses of NE, DHPG, DOPA, and DOPAC levels, the groups did not differ in proportionate increments in EPI levels. The results indicate that the ACTH response to hypoglycemia depends on availability of CRH outside the blood-brain barrier-presumably in the pituitary gland. The findings with icv alpha-helical h/r CRH9-41 can be explained by failure of the antagonist to reach effective concentrations at central sites of action of endogenous CRH, or by mechanisms other than CRH release determining the adrenomedullary response to hypoglycemia. Lewis rats seem to have less adrenomedullary secretion at baseline and smaller responses of NE synthesis and release during hypoglycemia than do Fischer 344/N rats. Neurochemical evidence for differential adrenomedullary and sympathoneural responses during hypoglycemia in all three rat strains is inconsistent with Cannon's view of a functionally unitary sympathoadrenal system. Since Lewis and Fischer 344/N rats had similar proportionate responses of both ACTH and EPI levels during hypoglycemia, either Lewis rats have deficient CRH responses to some stressors but not to others, or else pituitary-adrenocortical and adrenomedullary responses in this setting depend on mechanisms other than CRH release in the brain. Both explanations are inconsistent with the doctrine of non-specificity, the main tenet of Selye's stress theory. C1 BEILINSON MED CTR,DEPT MED,IL-49100 PETAH TIQWA,ISRAEL.

The role of the adrenal medulla in the specificity of these responses was studied in rats subjected to osmotic and non-osmotic stress two months following adrenal demedullation or sham operation. Basal and stimulated plasma corticosterone, aldosterone, ACTH and PRA levels in adrenal demedullated rats were similar to those in the sham operated groups indicating recovery of adrenocortical function. Basal plasma VP levels were similar in sham operated controls and adrenal demedullated rats (0.93+/-0.13 and 1.0+/-0.1 pg/ml, respectively) and rose to comparable levels in both groups following 48 h osmotic stimulation by water deprivation (14.4+/-1.3 and 20.7+/-3.4, respectively). On the other hand, while in sham operated rats, immobilization for 15 min, a non-osmotic stress, had no effect on plasma VP levels in control or water deprived (2.0+/-0.9 and 15.0+/-2.7 pg/ml), in adrenal demedullated rats, caused dramatic increases in plasma VP from 1.0+/-0.1 to 126.0+/-29.9 pg/ml in controls, and from 20.7+/-3.4 to 155+/-37 pg/ml in water deprived rats. Intraperitoneal hypertonic saline injection, a combination of osmotic and painful stress, caused much higher increases in plasma VP in adrenal demedullated rats (138.0+/-22.1 compared with 34.7+/-3.7 pg/ml in sham operated rats). Water deprivation potentiated this response to 70.0+/-8.3 and 295+/-24 pg/ml in sham operated and adrenal demedullated rats, respectively. VP mRNA measured by in situ hybridization, and irVP measured by immunohistochemistry, were elevated in magnocellular neurones in the hypothalamus of adrenal demedullated rats. The demonstration of marked plasma VP responses to non-osmotic stimuli in adrenal demedullated rats, suggests a modulatory role for the adrenal medulla in the specificity of the secretory responses of the magnocellular and parvicellular vasopressinergic systems.

The specificity for the location of a sound source in azimuth was measured in single neurons of the anterior ectosylvian (AE) region of the cat's cortex, which includes the anterior auditory field (AAF) and the anterior ectosylvian auditory field (AEA). 2. The influence of visual experience on auditory spatial tuning of these neurons was determined by comparing responses in cats with binocular deprivation from birth with those in normal control cats. 3. Spatial tuning was measured under near free-field conditions by presenting broadband sounds through a speaker in seven different azimuthal locations, from -60 to +60-degrees at 20-degrees intervals. Elevation was constant at the cats' ears. 4. In normal cats, a little over one-half of the neurons in the AE region (82/146 = 56%) showed some degree of azimuthal spatial tuning, as defined by at least a 2:1 ratio of responses between best and worst location. The rest (44%) were omnidirectional. 5. In binocularly deprived cats, a significantly higher proportion (70/82 = 86%) of the neurons in the AE region were spatially tuned. Only 14% were omnidirectional. Median spatial tuning width was significantly sharper than in normal cats. 6. We conclude that visual deprivation from birth induces intermodal changes that enhance the response specificity of neurons in the auditory cortex. These modifications may constitute the neural basis of behavioral compensation for early blindness. C1 NIMH,NEUROPHYSIOL LAB,UNIT NEUROETHOL,POB 608,POOLESVILLE,MD 20837.

Over 300 neurons were tested in each group with auditory, visual, and somatosensory stimuli. We confirmed the existence of an anterior ectosylvian visual area (AEV) in the fundus and ventral bank of the AE sulcus. Neurons in AEV had purely visual responses in normal cats. In visually deprived cats, by contrast, only a minority of cells in this area still responded to visual stimulation. Instead, most cells reacted vigorously to auditory and, to some extent, somatosensory stimuli. The few remaining visual neurons were also driven by auditory or somatosensory stimuli. No increase in the number of unresponsive neurons was found. It appears, therefore, that a cortical region that normally represents visual activity can become driven by auditory or somatosensory activity as a result of visual deprivation. Our results imply that early blindness causes compensatory increases in the amount of auditory cortical representation, possibly by an expansion of nonvisual areas into previously visual territory. In particular, they provide evidence for the existence of neural mechanisms for intermodal compensatory plasticity in the cerebral cortex of young animals. The changes described here may also provide the neural basis for a behavioral compensation for early blindness described elsewhere. C1 MAX PLANCK INST BIOL CYBERNET,W-7400 TUBINGEN,GERMANY.

They then received bilateral removals of either the amygdaloid complex and underlying cortex, the hippocampal formation and underlying cortex, or both combined, or they were retained as unoperated controls. After surgery or rest, the monkeys were tested for their retention of the preoperatively learned set of paired associates, as well as for their ability to learn new associations of the same type. Both unoperated controls and hippocampectomized monkeys relearned the preoperatively trained set of paired associates almost immediately. By contrast, monkeys with amygdala removals were moderately retarded in relearning, and monkeys with combined amygdala and hippocampal ablations were severely retarded. When confronted with new sets of visual stimuli, monkeys with amygdala removals or hippocampal removals learned new sets of paired associates at the same rate as the controls, whereas monkeys with the combined ablation were again profoundly retarded. Only one monkey with the combined lesion was able to learn new stimulus-stimulus associations to criterion, and then only after extensive training, despite the ability of all three animals in this group to perform delayed matching-to-sample with the same stimuli and the same intratrial delays as those used in the paired associate task. At the end of the main experiment, two of the unoperated controls received bilateral ablations of the rhinal cortex. These monkeys showed the same level of difficulty in learning new paired associates as the animals in the main experiment that had received the combined amygdala plus hippocampal ablations. The results implicate the medial temporal lobe, and particularly the rhinal cortex, in the formation of stimulus-stimulus associative memories. C1 UNIV OXFORD,DEPT EXPTL PSYCHOL,OXFORD,ENGLAND.

Many malignant gliomas overexpress growth factor receptors. The possibility of targeting these receptors with selective cytotoxic molecules constructed by fusing deoxyribonucleic acid (DNA)-encoding mutant forms of Pseudomonas exotoxin A (PE) with complementary DNA-encoding growth factors was investigated. Several recombinant toxins have been produced, including those in which transforming growth factor (TGF)-alpha, insulin-like growth factor (IGF)-I, and acidic fibroblast growth factor (FGF) were fused to mutant forms of PE lacking the native cell-binding domain. These recombinant proteins are cytotoxic to cells that express specific cell-surface receptors. The cytotoxic activity of TGF-alpha, IGF-I, and acidic FGF chimeric toxins was tested in vitro against human glioblastoma cell lines. Each recombinant toxin exhibited potent and specific killing of cells. The TGF-alpha-PE40 construct was cytotoxic to seven of the eight cell lines and was active at concentrations as low as 0.5 ng/ml (1.1 x 10(-11) M). The acidic FGF-PE40 toxin was also active on seven of the eight cell lines but was 50-fold less active than the TGF-alpha-PE40. The IGF-I-PE40 construct was active on only two cell lines. To determine the possible therapeutic effect in animal TGF-alpha-PE40 was administered to nude mice bearing subcutaneous human glioblastoma xenografts. The animals were treated for 7 days via a continuous infusion pump placed in the peritoneal cavity. A constant serum level of TGF-alpha-PE40 was achieved that was nontoxic to the mice yet caused a reduction in tumor volume and retarded growth beyond the treatment period. The overexpression of the epidemal growth factor receptor in glioblastomas multiforme and the potency and specificity of the TGF-alpha-PE40 construct designed to target this receptor suggests that TGF-alpha-PE40 has the potential to be an effective antitumor agent for the adjuvant therapy of these carcinomas.

An activating missense mutation in the gene for the alpha subunit of G(s), the G protein that stimulates cyclic adenosine monophosphate formation, has been reported to be present in these patients. The mutation is found in variable abundance in different affected endocrine and nonendocrine tissues, consistent with the mosaic distribution of abnormal cells generated by a somatic cell mutation early in embryogenesis. We describe three patients with MCAS who had profound endocrine and nonendocrine-disease and who died in childhood. Two of the patients were severely ill neonates whose complex symptoms did not immediately suggest MCAS. A mutation of residue Arg201 of G(s)alpha was found in affected tissues from all three children. A review of the literature and unpublished case histories emphasizes the existence of other patients with severe and unusual clinical manifestations. We conclude that the manifestations of MCAS are more extensive than is generally appreciated, and may include hepatobiliary disease, cardiac disease, other nonendocrine abnormalities, and sudden or premature death.

Design: Prospective, multicenter cohort study. Patients: Two hundred sixty inborn, very low birth weight (504 to 1500 gm) infants given ventilatory support from the first day of life. Results: The risk of an adverse outcome (death or chronic lung disease) changed with postnatal age at the time of diagnosis of the air leak. The association between air leak and an adverse outcome, as measured by gestational age-adjusted odds ratio (95% confidence interval), was 13.9 (i.7 to 114.6) for those in whom an air leak developed on day 0 or 1 (early), decreased to 1.7 (0.7 to 4.1) for those whose air leak developed on day 2 or 3 (intermediate), and increased to 16.6 (2.1 to 130.4) for those whose air leak developed on days 4 to 27 (late). The association with neonatal death showed even more striking fluctuations with postnatal age at occurrence of an air leak, ranging from an odds ratio of 40.3 (3.5 to 464.8) for the early group to 7.5 (2.3 to 25.0) for the intermediate group and 78.3 (6.9 to 889.5) for the late group. Conclusions: Air leak in newborn infants requiring mechanical ventilation is associated with increased risks of death or future morbidity, but the magnitude of these risks changes with postnatal age at the time of diagnosis of the air leak. Failure to consider the age at which the air leak is detected may miss changes in its prognostic implications and may partly explain inconsistent results in previous studies.

Many of the behavioral effects of NPFF have also been observed with the invertebrate neuropeptide Phe-Met-Arg-Phe-amide (FMRFamide), which binds to NPFF receptors because of its low homology to the C-terminal portion of NPFF. A competitive ligand binding assay was used to characterize NPFF receptors in rat spinal cord and a strong requirement was found for the C-terminal Arg-Phe-amide. It was found that FMRFamide (K(i):= 1.8 nM) bound with lower affinity than NPFF (0.26 nM) but it was about 7-fold more potent than PQRFamide (12 nM). This finding explains the similar bioactivities of NPFF and FMRFamide. The Gln2 appeared to be the cause of the relatively low potency of PQRFamide, based on the binding specificity of NPFF receptors for a series of FMRFamide analogs. In contrast to the Arg-Pheamide, substitutions at the first and second positions of FMRFamide were generally tolerated, with the most potent analogs being PMRFamide (K(i) = 0.54 nM), FFRFamide (0.25 nM) and FWRFamide (0.42 nM). Among the most potent ligands was a pentapeptide containing a photoreactive Phe analog, D-Tyr-(p-benzoyl-Phe)-norLeu-Arg-Phe-amide K(i) = 0.23 nM). It was found that dansyl-PQRFamide and dansyl-RFamide also bound to NPFF receptors with K(i) values of 6.1 and 73 nM, respectively. The radioligand binding and G-protein coupling of NPFF receptors were not altered by chronic morphine treatment.

Inhibition of the enzyme by DAMGO and Tyr-D-Arg-Phe-Sar was antagonized by the mu-selective competitive antagonist, CTOP D-Phe-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2, and the noncompetitive mu antagonists, beta-funaltrexamine and naloxonazine. Inhibition of adenylyl cyclase activity by the delta-selective ligands, DPDPE, DSLET and [D-Ala2]-deltorphin II was unaffected by these antagonists. Conversely, the de/ta-selective antagonists, ICI 174,864 N-allyl2-Tyr-(alpha-aminisobutyric acid)2-Phe-Leu-OH and naltrindole, blocked the effects of the delta but not the mu opioid ligands. Adenylyl cyclase activity in nucleus accumbens and in caudate putamen is subject to regulation by both mu and delta opioid receptors. C1 UNIFORMED SERV UNIV HLTH SCI,DEPT PHARMACOL,BETHESDA,MD 20814.

The 0.3 and 1 mg/kg doses of cocaine potentiated the pressor response to exogenous norepinephrine (0.2 mug/kg), whereas lower (0.03 and 0.1 mg/kg) and higher (3 and 5.6 mg/kg) doses were ineffective. Desipramine (0.03-1 mg/kg), a prototype norepinephrine uptake blocker, did not alter blood pressure or heart rate. Nisoxetine (0.01 -1 mg/kg), another norepinephrine selective uptake blocker, produced a small and brief (<5 min) pressor response, but no tachycardiac response. Unlike cocaine, both desipramine and nisoxetine produced a dose-dependent potentiation of the pressor response to norepinephrine with the maximal potentiation exceeding that of cocaine. Plasma norepinephrine and epinephrine levels were increased by cocaine (3 mg/kg), but not by nisoxetine (1 mg/kg). Chemical sympathectomy by 6-hydroxydopamine selectively antagonized cocaine-induced increases in both blood pressure and plasma norepinephrine levels, but did not alter cocaine-induced increases in heart rate or plasma epinephrine levels; the converse was the case with adrenal demedullation. Both the combination of chemical sympathectomy and adrenal demedullation and pretreatment with chlorisondamine (10 mg/kg) antagonized cocaine-induced pressor and tachycardiac effects and cocaine-induced increases in plasma epinephrine and norepinephrine levels. In the control group, cocaine (3 mg/kg) produced a biphasic increase in blood pressure consisting of an early peak increase of 52 +/- 2.5 mm Hg 15 sec after its injection followed by a quick and partial recovery to an increase of 20.5 +/- 3.3 mm Hg at 1 min which gradually declined to base-line values in about 30 min. Prazosin (1 mg/kg) pretreatment decreased the magnitude of the initial peak pressor response produced by cocaine and reversed the sustained pressor response to cocaine to a depressor response; the reversal of the pressor response to cocaine to a depressor response by prazosin was not seen after erythro-dl-1-(7-methylindan-4-yloxy)-3-isopropylaminobutan-2-ol (ICI 118,551) (3 mg/kg) treatment or adrenal demedullation. Treatment with ICI 118,551 alone enhanced the magnitude of the sustained phase of the pressor response to cocaine. These results indicate that inhibition of peripheral sympathetic neuronal amine uptake mechanism by cocaine is not critical for initiating its pressor, tachycardiac and plasma catecholamine increasing effects in conscious rats and that central stimulation of sympathoadrenal neural axis activity plays an important role in these effects. The data further suggest that peak pressor effects of cocaine are mediated by norepinephrine of sympathetic neural origin and peak tachycardiac effects of cocaine are mediated by epinephrine of adrenal medullary origin. Cocaine also produces a beta-2 adrenoceptor-mediated depressor response through the release of epinephrine from the adrenal medulla which in turn modulates its alpha-1 adrenoceptor-mediated pressor response.

Osmotic minipumps containing either saline or naltrexone were subcutaneously implanted into Buffalo rats that had been injected intraperitoneally with 7315c cells. Fourteen days after the pumps were implanted, 7315c tissue and brain tissue were removed and examined for their ability to bind [H-3]DAMGO and to respond to morphine (or DAMGO) and guanosine 5'-O-(3-thiotriphosphate) in an adenylyl cyclase assay. Naltrexone treatment caused a doubling in the density of [H-3]DAMGO binding sites in both whole brain membranes and the 7315c cell membranes. Naltrexone treatment may have slightly diminished the affinity of mu opioid receptors for [H-3]DAMGO (by 1.5- to 2-fold), but the precision of the assay was inadequate to determine whether this difference was significant. Naltrexone treatment also had no effect on the potency or efficacy of guanosine 5'-O-(3-thiotriphosphate) in diminishing [H-3]DAMGO binding to either whole brain or 7315c cell membranes. The influence of naltrexone treatment on opioid inhibition of adenylyl cyclase activity was also investigated in both tissues. In 7315c membranes, naltrexone treatment caused a 40% increase in the efficacy (maximal effect) of morphine but had no effect on the potency (IC50) Of morphine in inhibiting forskolin-stimulated adenylyl cyclase activity. In whole brain membranes from control rats, DAMGO failed to affect significantly forskolin-stimulated adenylyl cyclase. However, in whole brain membranes from naltrexone-treated rats, DAMGO caused a 30% inhibition of forskolin-stimulated adenylyl cyclase activity. Finally, naltrexone had no effect on either the potency or efficacy of guanosine 5'-O-(3-thiotriphosphate) in inhibiting forskolin-stimulated adenylyl cyclase activity in either 7315c cell membranes or whole brain membranes.

The role of D1 receptors in the central and peripheral actions in cocaine were investigated by comparisons of cocaine with the stable charged cocaine analog, cocaine methiodide. Both cocaine and cocaine methiodide produced dose-related increases in lethality in male, Swiss Webster mice, with cocaine methiodide being slightly more potent than cocaine; however, only cocaine produced convulsions. Several dopamine D1 antagonists ([R-(+)-7-chloro-8-hydroxy-3-methyl-1-phenyl-2,3,4,5-tet-rahydro-1H-3-benzazephine] (SCH 23390), [(-)-trans-6,7,7a,8, 9,13b-hexahydro-3-chloro-2-hydroxy-N-methyl-5H-benzo-[d]naptho-{2-1-b}azepine (SCH 39166), 1-(2-bromo-4,5-dime-thoxybenzyl)-7-hydroxy-6-methoxy-2-methyl-1,2,3,4-tetrahy-droisoquinoline HBr (A-69024), [R-(+)-7-bromo-8-hydroxy-3-methyl-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine] (SK F83566)) produced dose-dependent protection against the lethal effects of both compounds. Protection against cocaine methiodide-induced lethality was conferred by lower doses of the D1 antagonists than those effective against cocaine. Stereoselectivity of this effect was demonstrated by the lack of activity of the inactive enantiomer of SCH 23390. The D2 antagonist haloperidol was ineffective against either cocaine- or cocaine methiodide-induced lethality. Lethal effects of the nondopaminergic local anesthetic, lidocaine, were not influenced by prior treatment with D1 antagonists. Lethal effects of cocaine were enhanced by both centrally and peripherally acting D1 agonists but not by the D2 agonist quinpirole. Cocaine methiodide-induced lethality was also enhanced by the peripherally active DA1 agonist, fenoldopam. These results establish an important role for D1 but not D2 receptors in the lethal effects of acutely administered cocaine and suggest that peripheral loci may be one pathophysiological target.

Etonitazene and alfentanil produced dose-dependent increases in tail-withdrawal latency up to the maximum possible latency of 20 sec in 48-degrees- and 55-degrees-C water. Nalbuphine, GPA 1657 and profadol produced the maximum possible effect only at 48-degrees-C, and were ineffective at 55-degrees-C. The opioid antagonist quadazocine produced a dose-dependent antagonism of all agonists except profadol. In a Schild plot analysis, apparent pA2 values for quadazocine with alfentanil, etonitazene and nalbuphine were homogeneous (7.3-7.7 mol/kg), suggesting their effects were probably mediated by mu opioid receptors. The apparent pA2 value for GPA 1657 was significantly lower (6.2 mol/kg), suggesting GPA 1657 may have produced antinociception by a non mu receptor-mediated mechanism. The selective delta antagonist naltrindole (0.32-1.0 mg/kg) antagonized the antinociceptive effect of GPA 1657. The kappa-selective antagonist nor-binaltorphimine (nor-BNI, 3.2 mg/kg) caused a small rightward shift in the GPA 1657 dose-effect curve. Nalbuphine, GPA 1657 or profadol produced a rightward shift in the alfentanil dose-effect curve in 55-degrees-C water, consistent with possible low-efficacy mu agonist effects of these compounds. These studies suggest agonists may be differentiated based on antinociceptive effectiveness, receptor selectivity and intrinsic efficacy in the rhesus monkey tail-withdrawal procedure.

This study was conducted to determine whether the acute administration of mazindol modulates the pharmacological effects of intravenous cocaine in humans. In a crossover study, twelve acute drug conditions were tested in randomized order under double-blind, double-dummy conditions in eight cocaine abusers. Cocaine (0, 12.5, 25 and 50 mg, i.v.) was administered in combination with mazindol (0, 1 and 2 mg given orally 2 hr before the cocaine injection). Physiological and subject- and observer-rated responses were measured. Cocaine and mazindol alone both significantly increased heart rate and blood pressure. Cocaine increased ratings on stimulant-like subjective effect measures, including desire for cocaine; mazindol had mild, stimulant-like subjective effects. There were significant interactions between the effects of cocaine and mazindol on heart rate and blood pressure, with combinations producing significantly larger and more sustained increases compared with cocaine alone. There was no evidence that mazindol substantially altered the magnitude or profile of the subjective effects of cocaine, including cocaine-induced craving for cocaine. These results do not support the utility of acute administration of mazindol in the treatment of cocaine abusers through a mechanism of modulation of cocaine's subjective effects. Furthermore, mazindol treatment may increase the cardiovascular risks of cocaine. C1 JOHNS HOPKINS UNIV,SCH MED,DEPT PSYCHIAT & BEHAV SCI,BALTIMORE,MD 21205.

No significant antinociceptive response could be demonstrated in the warm-water tail-flick test, 10 min after a 30-sec exposure of mice to water at 5-degrees-C. However, the i.c.v. morphine dose-response curve in mice exposed to CWSS was displaced significantly to the left when compared to that obtained in control (i.e., non-CWSS-exposed) mice. Although coadministration of the delta antagonist, N,N-diallyl-Tyr-Aib-Aib-Phe-Leu-OH 1 (ICI 174,864), with i.c.v. morphine did not produce antagonism of the antinociceptive action of this mu opiate, the leftward displacement of the i.c.v. morphine dose-response curve seen in CWSS-exposed mice was blocked in ICI 174,864-treated mice suggesting involvement of opioid delta receptors in the modulatory effect. Pretreatment of mice with the delta-1 antagonist, [D-Ala2, Leu5, Cys6] enkephalin, did not antagonize the antinociception of morphine and further did not antagonize the leftward displacement produced by exposure to CWSS. Pretreatment of mice with the delta-2 antagonist, 5'-isothiocyanate, also did not antagonize the antinociceptive effects of morphine but blocked the leftward displacement in the morphine dose-response curve associated with CWSS, suggesting involvement of an opioid delta-2 receptor in this effect. Pretreatment of mice with the mu antagonist, beta-funaltrexamine, produced a significant antagonism of the morphine antinociceptive effect as seen by a rightward displacement of the morphine dose-effect curve. Further, in these beta-funaltrexamine-pretreated mice, exposure to CWSS did not result in an enhancement of morphine potency. Finally, i.c.v. pretreatment of mice with antibodies raised against [Leu5]enkephalin, but not antibodies against [Met5]enkephalin, blocked the modulatory action produced by exposure to CWSS; both antibodies to [Met5]enkephalin or [Leu5]enkephalin did not alter the morphine response directly. These data suggest that modulation of morphine potency by exposure to CWSS involves activation of an opioid delta-2 receptor which may be functionally and/or physically associated with opioid mu receptors. Additionally, the modulatory action appears to be produced in the brain by release of a [Leu5] enkephalin-like molecule. Finally, these observations may provide, in part, a physiological basis for the observed increase in analgesic effectiveness of morphine in situations of stress.

Agonist-independent (inactivation) and agonist-induced (desensitization) refractory states of N-methyl-D-aspartate (NMDA) receptors were studied on cultured rat hippocampal neurones using whole-cell and inside-out patch-clamp techniques and a fast perfusion system. 2. Shortly after whole-cell formation, application of 100 mum NMDA in the presence of 10 mum glycine and 0.2 mm [Ca2+]o induced membrane currents that desensitized by 23 %. Repeated application of NMDA at 30 s intervals resulted in a progressive increase in the degree and rate of onset of NMDA receptor desensitization. 3. Test responses to NMDA recorded in the presence of 0.2 mm [Ca2+]o were reversibly inactivated by 60 % following a train of ten 1 s applications of NMDA delivered at 0.5 Hz in the presence of 2 mm [Ca2+]o; similar results were obtained with 2 mm [Sr2+]o and 2 mm [Ba2+]o. In the presence of Ca2+ or Sr2+, desensitization during the train of responses to NMDA increased by 14 and 19 % respectively, while with Ba2+ there was no increase in desensitization. 4. In the presence of 0.2 mm [Ca2+]o at a holding potential of -60 mV, or in the presence of 2 mm [Ca2+]o at a holding potential of + 50 mV, a train of ten applications of NMDA failed to induce either inactivation or an increase in desensitization of test responses to NMDA. These results suggest an important role for [Ca2+]o in the induction of both inactivation and desensitization of NMDA receptors. 5. Increasing the intracellular calcium concentration, [Ca2+]i, via repeated activation of voltage-gated Ca+ channels, resulted in a reversible inactivation of test responses to NMDA by 35 % but failed to increase desensitization. In neurones dialysed with intracellular solution containing 2-5 mm Ca2+ NMDA receptor desensitization was similar to that in neurones dialysed with 10 nm Ca2+. 6. Block of NMDA receptor-channels by 2 MM [Mg2+]o during the train application of NMDA prevented the induction of both inactivation and desensitization. In contrast 3 mm [Mg2+]i was ineffective. 7. The magnitude of both inactivation and desensitization of NMDA receptors was not affected by intracellular dialysis of ATP, the non-hydrolysable ATP analogue 5'-adenylylimido-diphosphate (AMP-PNP), different Ca2+ chelators (EGTA or BAPTA), the Ca2+-activated protease inhibitor (leupeptin), dithiothreitol, or the phosphatase inhibitors (okadaic acid and a calcineurin inhibitor). 8. Application of 2.5 mM Ca2+ to the cytoplasmic side of inside-out patches induced inactivation of NMDA responses similar in magnitude to the inactivation seen in whole-cell recording. Complete recovery from inactivation was, however, much faster (20 s) for inside-out patches than for whole-cell responses (usually 5-10 min). 9. These results suggest two distinct mechanisms for modulation of NMDA receptors by intracellular Ca2+. Desensitization of NMDA receptors is induced when both [Ca2+]i is increased and NMDA receptors activated by agonist. Inactivation of NMDA receptors is produced by increased levels of [Ca2+]i and does not require NMDA receptor activation for induction. C1 NICHHD,CELLULAR & MOLEC NEUROPHYSIOL LAB,BETHESDA,MD 20892.

The study was performed on a group of Swedish twins so that variance explained by heritability for Type A could first be removed from the equation. The overall Type A score had been found to relate to self-reported CHD in this population. The dependent variable was the standardized score residual remaining after removing the genetic variance (i.e., that explained by co-twin score and zygosity). Multiple regression analyses revealed that there were differences in the psychosocial components of the Type A residual in men and women. These results are discussed in terms of culturally accepted gender roles and their possible implications for health endpoints.

Two-stage sampling and separate extraction and analyses of PAH associated with aerosol particles and those present in the vapor state are usually performed. The ability of commonly used sorbents to retain particulate matter introduces a potential for reducing the time and cost of PAH evaluation procedures. The filtration efficiency of three sorbent media, Florisil, XAD-2, and polyurethane foam (PUF), for particles in 0.1 to 1 mum size range was studied using air flow rates from 4 to 250 L/min through a PS-1 sorbent cartridge. Theoretical considerations were used to identify the principal filtration mechanisms and to assess the predictability of the aerosol filtration performance of sorbent filters. The results of this study indicate XAD-2 to be an efficient filtration medium owing to the electrostatic enhancement of capturing and retaining aerosol particles. As a result of theoretical considerations, Brownian diffusion and inertial deposition were found to be major filtration mechanisms accompanied by electrostatic effects. While the efficiency of the diffusional deposition mechanism was reasonably well predicted with available theories, modeling of submicron particle impaction at higher fluid velocities appeared to be inadequate. Further developments are suggested to improve our understanding of filtration phenomena in sorbent beds under high flow rate conditions.

The purpose of this study was to assess the relation between the time of awakening and the time of onset of acute myocardial infarction. Background. Previous investigation has shown the onset of symptoms of acute myocardial infarction to have a primary peak 1 to 2 h after awakening. In studies not corrected for time of awakening, there appears to be a late afternoon/early evening peak, but data correlating the onset of symptoms with awakening have been limited by small numbers of patients, perhaps precluding identification of a secondary peak. Methods. In the Cardiac Arrhythmia Suppression Trial (CAST), 3,549 patients had a documented myocardial infarction and entered antiarrhythmic drug titration. Of these, 3,309 had data on the onset of symptoms relative to the time of awakening and form the basis of this report. Results. A total of 870 patients (26.3%) were awakened by symptoms. Of the remaining 2,439 patients who were not awakened by symptoms, 798 (32.7%) experienced the onset of symptoms in the lst 4 h after awakening (with the highest number in the 1st h), after which the incidence of symptom onset decreased in a linear fashion, with a secondary peak 11 to 12 h after awakening. Both peaks are statistically significant. A similar pattern was seen in most of the subgroups examined (based on age, gender and various other demographic characteristics). Conclusions. Analysis of the very large CAST data base confirms the relation between awakening and onset of symptoms of myocardial infarction, suggesting involvement of the morning catecholamine surge. A secondary peak in symptom onset, occurring 11 to 12 h after awakening, is a new observation and may relate to ingestion of the evening meal or other trigger factors concentrated in those hours.

The purpose of this study was to evaluate the long-term prognostic role of asymptomatic ventricular arrhythmias in original Framingham Heart Study subjects and Framingham Offspring Study subjects who had echocardiographic evidence of left ventricular hypertrophy. Background. Echocardiographically determined left ventricular hypertrophy is associated with increased risk for ventricular arrhythmias. There are no population-based data available with regard to the long-term prognostic implications of asymptomatic ventricular arrhythmias in subjects with left ventricular hypertrophy. Methods. In a population-based cohort study, we studied 224 men and 393 women with echocardiographically determined left ventricular hypertrophy who were free of coronary heart disease and had 1-h ambulatory electrocardiograms at the baseline examination. The age-adjusted prevalence of complex or frequent ventricular arrhythmias (>30 ventricular premature beats/h, multiform premature complexes, couplets, ventricular tachycardia or R on T ventricular premature complexes) was 28% (51 of 224) in men and 17% (71 of 393) in women. The mean follow-up period was 5.7 years for cohort and 4.5 years for offspring subjects. Results. In men with complex or frequent arrhythmias, the 6-year cumulative incidence of all-cause mortality was 38%, whereas in those free of arrhythmia it was 12%; corresponding values in women were 22% and 11%. The cumulative incidence of myocardial infarction or death due to coronary heart disease was 20% for men with and 10% for men without arrhythmia, but in women little difference was noted (5% vs. 4%). After adjustment for age and gender in a Cox proportional hazards model, subjects with complex or frequent arrhythmia were at increased risk for all-cause mortality (hazard ratio 1.80, 95% confidence interval [CI] 1.13 to 2.87, p = 0.013). After adjusting for eight clinical covariates, the increased risk for all-cause mortality remained marginally significant (hazard ratio 1.62, 95% CI 0.98 to 2.68, p = 0.058). No significant increased risk was noted for myocardial infarction or death due to coronary heart disease. Conclusions. In subjects with left ventricular hypertrophy, the presence of asymptomatic ventricular arrhythmias was associated with higher mortality, which was statistically significant after adjusting for age and gender and marginally significant after taking into account other covariates.

Data from the Framingham Heart Study indicate that the incidence of congestive heart failure increases with age and is higher in men than in women. Hypertension and coronary heart disease are the two most common conditions predating its onset. Diabetes mellitus and electrocardiographic left ventricular hypertrophy are also associated with an increased risk of heart failure. During the 1980s, the annual age-adjusted incidence of congestive heart failure among persons aged greater than or equal to 45 years was 7.2 cases/1,000 in men and 4.7 cases/1,000 in women, whereas the age adjusted prevalence of overt heart failure was 24/1,000 in men and 25/1,000 in women. Despite improved treatments far ischemic heart disease and hypertension, the age-adjusted incidence of heart failure has declined by only 11%/calendar decade in men and by 17%/calendar decade in women during a 40-year period of observation. In addition, congestive heart failure remains highly lethal, with a median survival time of 1.7 gears in men and 3.2 years in women and a 5-year survival rate of 25% in men and 38% in women.

Design: Observational population-based study Setting: Four U.S. communities: Forsyth County, North Carolina; Sacramento County, California; Washington County, Maryland; and Pittsburgh, Pennsylvania. Participants: 5,201 men and women aged 65 years and older. Measurements: Demographic data; histories of cardiovascular disease (CVD), chronic lung disease, arthritis, diabetes, and hypertension; measures of subclinical disease including arm and ankle blood pressures, internal carotid wall thickness and stenosis, ejection fraction, left ventricular mass, fractional shortening, and diastolic function, electrocardiographic left ventricular hypertrophy and cardiac injury score, forced expiratory flow and volume; functional status including self-reported physical functioning, hearing and sight limitations and health status, and performance-based measures of function. These variables were examined among men and women in three age groups: 65-74 years, 75-84 years, and 85+ years. Subgroups of participants with and without manifest CVD were also examined. Main Results: In women, the prevalence of CVD and other chronic conditions increased with age, and the highest rates occurred among those 85 years and older. In men, prevalence rateS increased between the two younger groups, but the oldest group had lower than expected rates for coronary heart disease, cerebrovascular disease, hypertension, and chronic lung disease. In contrast, there were strong age-related linear trends in most of the subclinical measures of blood pressure atherosclerosis and pulmonary function and in virtually all measures of functional status in both gender groups across the age range. There was a particularly marked decline in functional status between the two older age groups. While subclinical disease was greater and functional status was poorer among those with manifest CVD, with few exceptions, age-related trends were not significantly different between the two groups. Conclusions: Lower than expected prevalence rates of CVD among those aged 85 years and older, particularly among men, in this study of community-dwelling elderly may represent selection bias or a real plateauing in disease prevalence with age. However, subclinical disease appears to increase and functional status to decline across the age range in both men and women regardless of the presence of CVD. The apparent increase in subclinical disease with age indicates potential for CVD prevention after age 65. C1 UNIV WASHINGTON,DEPT BIOSTAT,SEATTLE,WA 98195.

Design: Prospective cohort study. Setting: Eight proprietary NHs in Maryland. Subjects: Four hundred thirty new admissions age 65 or older who were participants in a larger prospective study of mental morbidity and adjustment to the NH. Measures: Nurses aides' reports of continence status, psychiatric examinations, and nursing staff assessments of mobility at 2 weeks, 2 months, and 1 year after NH admission. Results: The prevalence of daytime UI at admission was 39% in both females and males. Among the 293 members (68%) of the admission cohort remaining in the NHs 2 months after admission, the incidence of daytime UI was 27% (21% in females, 51% in males); daytime UI resolved in 23% (24% in females, 20% in males). Among the 178 members (41%) of the admission cohort remaining in the NHs 1 year after admission, the incidence of daytime UI between 2 months and 1 year after admission was 19% (16% in females, 46% in males); daytime UI resolved in 22% (23% in females, 14% in males). The continence status of about two-thirds of residents remaining in the NH at 1 year after admission was stable over time: 22% had daytime UI, and 42% were continent at all three data collection points. The development of daytime UI was associated with male sex, the diagnosis of dementia, fecal incontinence, and the inability to ambulate or transfer independently. Resolution of daytime UI was associated with the absence of these characteristics. Conclusions: Despite limitations attributable to the method of defining UI and potential biases related to the attrition of the admission cohort over time, this is the first large prospective study to examine the incidence and remission patterns of daytime UI among NH residents. The strong association between UI and dementia was validated for the first time by direct psychiatric examinations. Sex and mobility are also closely associated with the development and remission of UI in this setting. This study provides some valuable data that can be used to assess the impacts of the recently developed Resident Assessment Protocol for UI and Agency for Health Care Policy and Research Clinical Practice Guidelines.

In mammals, a limited number of P-450s are involved in metabolic pathways of steroid synthesis, while most of these enzymes are involved in metabolism of foreign compounds. The principal beneficial function of P-450s is to convert chemicals into derivatives that can be easily eliminated from the body. This generally occurs through P-450-mediated oxidations of hydrophobic substances followed by conjugation reactions. For many foreign compounds, P-450 metabolism results in production of ''activated'' metabolites that can cause cell death and gene mutations. During the past several years, it has become widely recognized that marked species differences occur among the foreign compound-metabolizing P-450s. In addition to this interspecies variability in metabolism, marked intraspecies variability, frequently referred to as drug oxidation polymorphisms, occurs in virtually all mammals examined to date. Based on these observations, it is necessary to develop new human P-450-based systems that can be used to study foreign compound metabolism in order to predict human risk. This is being accomplished by use of cDNA-directed expression in B lymphoblastoid cells. These cells can be used to predict how humans will metabolize a chemical and whether it will be metabolically activated to a toxic or mutagenic metabolite. To study human P-450 polymorphisms, polymerase chain reaction (PCR) assays have been developed for diagnosis of known mutant P-450 genes. Molecular probes are also being used to screen populations for levels of expression of carcinogen-activating P-450s in an effort to determine whether expression of certain P-450 forms is associated with increased risk for development of environmentally based disease.

For investigation of the role of this gene in tumors in cats, feline p53 cDNA was molecularly cloned by PCR amplifications using primers based on the sequences conserved among several species. The cloned cDNA appeared to cover approximately 90% of the open reading frame of the feline p53 gene and had characteristic structures in common with the p53 genes of several other species. The amino acid sequence similarities of the feline p53 with the human, mouse, rat and chicken counterparts were 82.9%, 75.6%, 76.5% and 57.2% respectively. Moreover, using a panel of feline x rodent somatic cell hybrids, the feline p53 gene was assigned to feline chromosome E1. These data will be useful for determining the role of the p53 tumor suppressor gene in feline tumors. C1 NATL INST ANIM HLTH,IMMUNE CYTOL LAB,IBARAKI 305,JAPAN.

The proviruses of these nondefective MuLVs have been shown to act as insertion mutagens most frequently activating an adjacent cellular gene involved in cell growth control. Mutations by provirus insertions, recognized as common provirus integration sites, have been instrumental in identifying novel cellular genes involved in tumor formation. We have searched for new common provirus integration sites in Moloney MuLV-induced thymomas. Using cellular sequences flanking a provirus cloned from one of these tumors, we found one region, designated Mis-2, which was the target of provirus integration in a low (3%) percentage of these tumors. Mis-2 was mapped on mouse chromosome 10, approximately 160 kbp downstream of myb. The Mis-2 region may contain a novel gene involved in tumor development.

We now present evidence that the 17-kDa protein product of the A1L gene can function in vitro as a transcription factor. Simultaneous overexpression of the transactivators was achieved by coinfecting HeLa cells with one recombinant vaccinia virus that encodes the bacteriophage T7 RNA polymerase and three recombinant vaccinia viruses that contain copies of A1L, A2L, and G8R ORFs regulated by T7 promoters. Extracts from the recombinant virus-infected cells exhibited greatly enhanced late in vitro transcription activity and served as a source of factors. The 17-kDa product of the A1L ORF represented approximately 8% of the ammonium sulfate-precipitated cell protein and copurified with a late transcription factor activity. The transcription factor activity could be specifically immunodepleted with immobilized antibody to the bacterially expressed A1L-encoded protein, providing additional evidence for its identity and role. A sequence encoding six consecutive histidines was added to the AIL ORF, which was then incorporated into the genome of a baculovirus expression vector. The 17-kDa protein, synthesized in insect cells and purified by binding to an Ni2+-chelating affinity column, could replace the vaccinia virus-overexpressed 17-kDa protein in transcription assays. In addition to the 17-kDa product of the A1L gene, which was named vaccinia virus late transcription factor 2, the proteins that stimulate specific transcription of late promoter-regulated templates included the viral multisubunit RNA polymerase, vaccinia virus late transcription factor 1 (the product of the G8R ORF), and at least one other partially purified protein.

We have expressed the A2L open reading frame in Escherichia coli and shown by blotting experiments that the 26-kDa protein binds zinc, a property predicted by the presence of a CX2CX13CX2C zinc finger motif. The specificity for zinc binding was demonstrated by competition with other metals. The role of the sequence motif in zinc binding was established by analysis of a series of mutations, including truncations and conservative single amino acid substitutions. Mutations that reduced zinc binding in vitro prevented the ability of A2L to transactivate late genes in vivo. C1 NIAID,VIRAL DIS LAB,BETHESDA,MD 20892.

In order to relate these phenotypic differences to primary genomic features, we constructed a series of chimeric plasmids between a full-length replication-competent molecular clone of ADV-G and subgenomic clones of ADV-Utah 1 representing map units (MU) 15 to 88. After transfection of the plasmids into cell culture and serial passage of cell lysates, we determined that substitution of several segments of the ADV-Utah 1 genome (MU 15 to 54 and 65 to 73) within an infectious ADV-G plasmid did not impair the ability of these constructs to yield infectious virus in vitro. Like ADV-G, the viruses derived from these replication-competent clones caused neither detectable viremia 10 days after inoculation nor any evidence of Aleutian disease in adult mink. On the other hand, other chimeric plasmids were incapable of yielding infectious virus and were therefore replication defective in vitro. The MU 54 to 65 EcoRI-EcoRV fragment of ADV-Utah 1 was the minimal segment capable of rendering ADV-G replication defective. Substitution of the ADV-G EcoRI-EcoRV fragment into a replication-defective clone restored replication competence, indicating that this 0.53-kb portion of the genome, wholly located within shared coding sequences for the capsid proteins VP1 and VP2, contained a determinant that governs replication in cell culture. When cultures of cells were studied 5 days after transfection with replication-defective clones, rescue of dimeric replicative form DNA and single-stranded progeny DNA could not be demonstrated. This defect could not be complemented by cotransfection with a replication-competent construction.

L. Lodmell, J. W. Sumner, J. J. Esposito, W. J. Bellini, and L. C. Ewalt, J. Virol. 65:3400-3405, 1991). To improve our understanding of the mechanism(s) of this protection, we investigated whether sera of A/WySnj mice that had been vaccinated with RCN-N but not challenged with street rabies virus had anti-rabies virus activity. In vivo studies illustrated that mice inoculated in the footpad with preincubated mixtures of anti-N sera and virus were protected. In addition, anti-N sera inoculated into the site of virus challenge protected mice. The antiviral activity of anti-N sera was also demonstrated in vitro. Infectious virus was not detected in cultures 24 h following infection with virus that had been preincubated with anti-N sera. At later time points, infectious virus was detected, but inhibition of viral production was consistently greater-than-or-equal-to 99% compared with control cultures. The protective and antiviral inhibitory activity of the anti-N sera was identified as anti-N antibody by several methods. First, absorption of anti-N sera with goat anti-mouse immunoglobulin serum, but not normal goat serum, removed the activity. Second, radioimmuno-precipitation and sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of sucrose density gradient-fractionated anti-N sera showed that antiviral activity was present only in the fraction containing anti-N antibody. Finally, absorption of anti-N sera with insect cells infected with a baculovirus expressing the N protein removed the protective activity. These data indicate that anti-N antibody is a component of the resistance to rabies virus infections. C1 CTR DIS CONTROL & PREVENT,NATL CTR INFECT DIS,DIV VIRAL & RICKETTSIAL DIS,ATLANTA,GA 30333.

PTHrP is overexpressed in lymphocytes from adult T-cell leukemia patients. We now demonstrate that in the human T-cell lymphotropic virus type I-transformed cell line MT-2, RNA synthesis is initiated primarily at the P2 promoter. Furthermore, in cotransfection experiments, Tax1 transactivates the P2 promoter 10- to 12-fold. By using deletion and site-specific point mutations, we have identified a promoter-proximal sequence (positions -72 to -40) which is important for Tax1 transactivation. The PTHrP promoter-proximal element contains two potential overlapping Ets1 binding sites, EBS I and EBS II. Gel shift analysis demonstrated that Ets1 binds specifically to both EBS I and EBS II. Mutation of the consensus GGAA core motif in EBS I abolished binding and Tax1 transactivation in Jurkat lymphocytes. In Ets1-deficient cells, cotransfection of Tax, and Ets1 expression plasmids stimulates PTHrP promoter activity. In the absence of Ets1, minimal transactivation of the PTHrP promoter is observed. These data suggest that Ets1 binds to EBS I and cooperates with Tax, to transactivate the PTHrP P2 promoter. C1 NCI,MOLEC VIROL LAB,BETHESDA,MD 20892.

In these experiments, HeLa cell nuclear extracts were passed over affinity matrices containing chemically synthesized or bacterially expressed HIV-1 Tat. Assay of material that bound to and eluted from the Tat matrices revealed the presence of the Sp1 transcription factor. Other transcription factors (Oct and NF-kappaB) also bound to Tat matrices but with less efficiency-in parallel with the lower capacities of these binding motifs to confer Tat responsiveness on a basal HIV-1 promoter compared with Sp1 sites. Passage of nuclear extracts over matrices containing other neutral proteins, including bovine serum albumin, ovalbumin, and lysozyme, revealed no or reduced binding. Cross-linking experiments indicated that the purified Spl and Tat proteins can form multimeric complexes in the absence of other proteins. The region of Tat responsible for Sp1 binding was localized to a region encompassing residues 30 to 62. Immunoprecipitation experiments with HIV-1-infected T lymphocytes indicated coimmunoprecipitation of Tat and Sp1. These experiments extend previous genetic experiments and suggest a direct interaction between Tat and Sp1 during transactivation. C1 UNIV CALIF IRVINE,DEPT MOLEC BIOL & BIOCHEM,IRVINE,CA 92717.

Cordonnier, L. Montagnier, and M. Emerman, Nature [London] 340:571-574, 1989). To define the role of the corresponding region of HIV-2, we introduced single amino acid changes into the C4 sequence of HIV-2ROD. The effects of these mutations on glycoprotein function and on virus infectivity have been examined. We have shown that the tryptophan residue at position 428 is necessary primarily for CD4 binding. The isoleucine residue at position 421 is necessary for the establishment of productive infection in the promonocytic cell line U937, while it is dispensable to some extent for infection of primary T lymphocytes or the lymphocytic cell line SUP-T1. This replication defect correlated with the failure of the Ile-421-to-Thr (Ile-421-Thr) mutant glycoprotein to form syncytia in U937 cells. DNA analysis of revertant viruses revealed that a strong selective pressure was exerted on residue 421 of the surface glycoprotein to allow HIV-2 infection of U937 cells. These results demonstrate that this region of HIV-2 plays an important role in determining fusion efficiency in a cell-dependent manner and consequently can influence viral tropism.

Five pairs of macaques were inoculated with 10-fold dilutions of the virus stock, and one macaque was mock-infected. The virologic and clinical status of these macaques was monitored for up to 80 weeks. The MID50 Of SIV(mne) was determined to be 10(2) cell culture infectious dose of the original virus stock. In order to test the infectivity and pathogenesis of an established viral dose, six additional macaques were inoculated with 10x MID50 (10(3) cell culture infectious dose) of the SIV(mne). The virologic and clinical status of these macaques was monitored for 40 weeks. All of the macaques inoculated with 10x MID50 or greater became infected as evidenced by seroconversion and consistent virus isolation from peripheral blood mononuclear cells. Macaques infected with SIV(mne) had an initial sharp decrease in CD2, CD20, CD4, CD8, and CD4CD29 lymphocyte subsets, whereas the CD4:CD8 ratio increased. Viremic macaques developed persistent slight to moderate peripheral lymphadenopathy approximately 3 to 4 weeks after inoculation. Four macaques subsequently died of AIDS-like disease at 29, 33, 42, and 80 weeks after inoculation. Data obtained from the viral titration study and the acute infection model will aid in the development of animal trials to evaluate antiretroviral therapies and preventive vaccines against human immunodeficiency virus infection.

The type and size of the contact area of the upper jaws significantly affected the force required to break the pellets. Significant differences were observed between the flat-horizontal and concave receptacle bases in the force required to break the pellets when using the two round-flat upper jaws. In contrast, similar results were obtained with both bases when the bullet, chisel, or cone-shaped upper jaws were used. Autoclaved pellets were 69.4% (range, 49 to 94%) harder than preautoclaved pellets. These results suggest that different testing systems can be used for measuring pellet hardness and that a standard procedure must be used in order to compare pellet hardness results between different testing laboratories. It was concluded that the flat-horizontal base and the larger round-flat end upper jaw gave the most reproducible results for measuring pellet hardness.

In the multi-echo multi-slice experiment discussed in this paper, a threefold reduction in measurement time is obtained by sacrificing some spectral resolution. Signal-to-noise ratio and spatial resolution are preserved. Metabolite images of N-acetyl aspartate, and total choline + total creatine from multiple slices through the human brain are presented and compared with images obtained with a conventional single-echo multi-slice method.

Caloric restriction was achieved by means of the every-other-day (EOD) feeding regimen, maintained for various periods from 1 to 15 months. Protein lateral diffusion constant (D) in hepatocyte membranes was measured by means of fluorescence recovery after photobleaching (FRAP) in liver smears. The peroxide-induced autofluorescence (PIAF) was utilized as a fluorescent label. A mild (1 mM for 10 min) H2O2 treatment of liver smears produces oxidation of riboflavin that is bound to all proteins of the cell membrane. Using this technique, the average lateral diffusion constant (D) and the fractional recovery (FR) of these proteins can be measured. EOD feeding resulted in a significant decrease in body weights and also a significant increase in the values of D in all age groups after 1 month of EOD feeding. After 3.5 months of EOD feeding a further increase of D was observed (up to about 15%). Nevertheless no further change in D occurred if the EOD feeding was maintained for 6.5 or even 15 months. The negative linear age correlation of D observed in the AL-fed animals was present also under the EOD feeding; however, the whole regression equation shifted towards higher values. These experiments indicate that caloric restriction influences the lateral diffusion constant of membrane proteins in hepatocytes. The results are interpreted as a result of an increased protein turnover caused by the caloric restriction.

With this method, I e-examination of uncoupling by tryptic digest of the ATPase revealed that TD2 cleavage (Arg-198) had no effect on either occlusion or ATPase activity. Digestion past TD2 in the presence of 5 mM Ca2+ and at 25 degrees C resulted in the loss of about 70% of the ATPase activity, but no loss of occlusion. Digestion past TD2 in the presence of 5 mM Ca2+, 3 mM ATP, and at 25 degrees C resulted in a partially uncoupled enzyme complex which retained about 50% of the ATPase activity, but completely lost the ability to occlude Eu3+. Digest past TD2 in the presence of 5 mM Ca2+ and 3 mM AMP-PNP (a non-hydrolyzable ATP analog) at 25 degrees C resulted in no loss of occlusion,, thus revealing the absolute requirement of ATP during the digest to eliminate occlusion. From these findings we conclude that uncoupling of Ca2+ transport from ATPase activity is possible by tryptic digestion of the (Ca2+ +Mg2+)-ATPase. Interestingly, only after phosphorylation of the enzyme do the susceptible bond(s) which lead to the loss of occlusion become exposed to trypsin.

[H-3]-ryanodine binding was enhanced by AMP, Ca2+ and caffeine, and significantly diminished by ATP, Ba2+ and Sr2+. Furthermore, dantrolene and ruthenium red, two classical inhibitors of Ca2+ release from the SR, blocked [H-3]-ryanodine binding. Similarly, tetracaine, known to block the charge movement associated with excitation-contraction coupling in vertebrate muscle, inhibited the binding of the alkaloid. Our lobster SR preparation exhibited a single high-affinity ryanodine binding site (K-d = 6.6 nM, B-max = 10 pmol/mg protein). Since SDS-PAGE of the SR proteins revealed a major band c. 565 kDa which comigrated with the putative ryanodine receptor from both rat and chicken skeletal muscle, we concluded that lobster skeletal muscle is equipped with the 565 kDA ryanodine receptor. Finally, incorporation of the SR microsomal fraction from lobster into planar bilayer membranes revealed the presence of a ryanodine-sensitive Ca2+ channel activity (160 pS in symmetrical 200 mM CsCl solutions). We concluded that both the crustacean and vertebrate skeletal muscle ryanodine receptor share the relevant properties such as molecular weight and affinity for ryanodine and inositol 1,4,5 triphosphate. However, there are important differences between the two receptors including differential effects of the alkaloid on the Ca2+ release channel and modulation of the receptor by nucleotides.

We found that this induction was accompanied by increased levels of MHC class I mRNA, which was attributable to the activation of the two conserved upstream enhancers, region I (NF-kappaB like) and region II. This activation coincided with the induction of nuclear factor binding activities specific for the two enhancers. Region I binding activity was not present in undifferentiated NT2 cells, but binding of an NF-kappaB heterodimer, p50-p65, was induced following RA treatment. The p50-p65 heterodimer was produced as a result of de novo induction of p50 and p65 mRNAs. Region II binding activity was present in undifferentiated cells at low levels but was greatly augmented by RA treatment because of activation of a nuclear hormone receptor heterodimer composed of the retinoid X receptor (RXRbeta) and the RA receptor (RARbeta). The RXRbeta-RARbeta heterodimer also bound RA responsive elements present in other genes which are likely to be involved in RA triggering of EC cell differentiation. Furthermore, transfection of p50 and p65 into undifferentiated NT2 cells synergistically activated region I-dependent MHC class I reporter activity. A similar increase in MHC class I reporter activity was demonstrated by cotransfection of RXRbeta and RARbeta. These data show that following RA treatment, heterodimers of two transcription factor families are induced to bind to the MHC enhancers, which at least partly accounts for RA induction of MHC class I expression in NT2 EC cells.

Our laboratory previously reported that a DNA fragment containing 857 bp of 5'-flanking sequence of the human IL-2Rbeta gene exhibited promoter activity. We have now further characterized the promoter and delineated cis-acting regulatory regions. The region downstream of -363 is critical for basal and phorbol myristate acetate-inducible IL-2Rbeta promoter activity and contains at least three enhancer-like regions. Among them, the -56 to -34 enhancer was the most potent and had high-level activity in two T-cell lines but not in nonlymphoid HeLaS3 and MG63 cells. This enhancer contains a GGAA Ets binding site which bound two Ets family proteins, Ets-1 and GA-binding protein in vitro. Mutation of the Ets motif strongly diminished both promoter and enhancer activities. We conclude that this Ets binding site plays a key role in regulating basal and phorbol myristate acetate-inducible IL-2Rbeta promoter activity and may also contribute to tissue-specific expression of the IL-2Rbeta gene.

This small 44-amino-acid protein is thought to function through the activation of growth factor receptors. E5 activation of the epidermal growth factor receptor results in an increase in the number of activated receptors at the cell surface. This finding suggests that E5 may act by inhibiting the normal down regulation of activated epidermal growth factor receptor via coated pit-mediated endocytosis. We have constructed a fusion protein consisting of glutathione S-transferase and the conserved C-terminal domain of E5 (GST-E5) in order to identify E5-associated cellular proteins that may be involved in its transforming activity. We have identified a 125-kDa cellular protein with a strong associated serine kinase activity that specifically associated with GST-E5 in the reduced form but not with GST-E5 fusions that contained changes in several conserved amino acids. Microsequence and biochemical analyses suggest that p125 is a novel member of the alpha-adaptin family. Since alpha-adaptins have previously been shown to be involved in coated pit-mediated cell surface receptor endocytosis and down regulation, these results suggest that p125 may be an alpha-adaptin-like molecule involved in growth factor receptor down regulation and that E5 may act by inhibiting its activity.

The III nucleotides corresponding to the deleted amino acid sequence were found in a separate exon bounded by consensus intron/exon junction sequences in rat genomic DNA. A partial restriction map of genomic DNA bounding this region placed the deleted exon approximately 600 base pairs (bp) downstream of the upstream exon. RT/PCR analysis of RNA from different brain regions showed that the deletion variant is more abundantly expressed in the brain stem and cerebellum while the full-length form is expressed more abundantly in the olfactory bulb, striatum, hippocampus, and cortex. Northern analysis of poly(A)+ RNA from different brain regions with probes specific for the deleted exon (i.e., full-length form) and for the splice junction (deletion form) indicated approximately 4.4 kb transcripts. The probe for the deleted exon hybridized to transcripts in olfactory bulb, cortex, striatum, and hippocampus while the splice junction probe hybridized most strongly to transcripts in cerebellum. The results suggest an interesting rostral to caudal shift in the expression of splice variants of the NMDAR1 which may signify important functional differences in native forms of NMDA receptors.

A single d-amphetamine dose (7.5 mg/kg, i.p.) enhances behavioral sterotypy and augments brain expression of c-fos, fos-B, fra-1, zif 268, jun-B, and c-jun by 2-11 fold. When the single amphetamine dose is preceeded by 28 saline injections over 14 days, it is half as effective in enhancing expression of these genes. Rats injected with 7.5 mg/kg i.p. twice daily for 2 weeks and sacrificed after the last injection reveal further attenuation or abolition of the amphetamine-induced mRNA upregulation. These stigmata of 'tolerance' in gene expression display partial overlap with behavioral tolerance, manifest as changes in locomotor activity. Rats receiving low (2 mg/kg) amphetamine challenge doses following the 2-week 7.5 mg/kg b.i.d. amphetamine treatment show tolerance to the locomotor activating effects of the drug; no tolerance is evident following a high (7.5 mg/kg) challenge dose. These data suggest that amphetamine-induced alterations in brain transcription factor gene expression can display 'tolerance' and possibly 'cross-tolerance' with the stress caused by i.p. injection.

TGFbeta1 expression is largely governed by three AP-1 binding sites located in two different promoters of this gene. We have examined the ability of retinoid receptors to inhibit the activity of the two promoters (especially the promoter 1) by cotransfection assays in the hepatocellular carcinoma cell line HepG2. When the TGFbeta1 promoter activity is induced by 12-O-tetradecanoyl phorbol-13-acetate (an activator of AP-1-controlled gene transcription), this activity can be strongly repressed by retinoic acid receptor-alpha (RARalpha), RARbeta, or retinoid X receptor-alpha (RXRalpha) as well as other members of the nuclear receptor family. Repression was hormone dependent and a function of receptor concentration. Heterodimerization of RARa or RARbeta with RXRalpha did not modify the inhibition activities of these receptors, indicating that heterodimer formation is not required for antagonizing of AP-1 activity. On further examining the anti-AP-1 activity of RXRalpha we observed that three different AP-1-controlled promoters (TGFbeta1, collagenase, and cFos) can be inhibited. Using gel shift assays, we demonstrated that RXRalpha inhibits Jun and Fos DNA binding and that 9-cis RA enhances this inhibition, suggesting that a mechanism involving direct protein-protein interaction between RXR and AP-1 components mediates the inhibitory effect observed in vivo. Transfection analyses with RXRalpha point mutations revealed that residues L422, C432, and, to a lesser extent, residues L418 and L430, are involved in ligand-induced anti-AP1 activity of RXRalpha in vivo. Thus both types of retinoid receptors can inhibit AP-1-activated promoters, including the TGFbeta1 gene promoter, via a mechanism that involves protein-protein interaction.

We found that NF-kappaB induction did not require contact between the APCs and T lymphocytes and could be achieved by medium conditioned by the APCs. The APCs were found to express low levels of mRNA for TNFalpha. The addition of antibody against TNFalpha blocked the ability of APCs to induce NF-kappaB. These observations were extended by the finding that NF-kappaB was also induced in T lymphocytes separated by a membrane from a mixture of T lymphocytes, splenic APCs and antigen by a TNFalpha-dependent mechanism. Together, these findings suggest that induction of NF-kappaB in antigenically stimulated or 'bystander' T cells may take place through stimulation by TNFalpha as well as in response to T cell receptor occupancy.

Bacterial conjugation is probably the most important mechanism by which genes are spread among prokaryotes and perhaps also contributes to eukaryotic evolution. Conjugation is mediated by plasmids. The mechanism of conjugation remains ill-understood despite progress in the identification, mapping and sequencing of genes required for plasmid transmission. All conjugation-specific genes (those required only for DNA transfer and establishment) identified to date map to plasmids. We found that IncP plasmids could enter and subsequently convert maxicells, which are trapped in a metabolic state that prevents de novo expression of chromosomal genes, into conjugative donors. This suggests that IncP plasmids encode not only necessary functions but indeed all functions specific to DNA transmission. Thus, like viruses, plasmids can convert non-viable cells into gene vectors. RP HEINEMANN, JA (reprint author), NIAID,LMSF,ROCKY MT LABS,HAMILTON,MT 59840, USA.

REP sequences are defined as conserved repetitive extragenic palindromic sequences and are found in Escherichia coli, Salmonella typhimurium and other closely related enteric bacteria. These REP sequences may participate in the folding of the bacterial chromosome. In this work we describe a unique class of 28 conserved complex REP clusters, about 100 bp long, in which two inverted REPs are separated by a singular integration host factor (IHF) recognition sequence. We term these sequences RIP (for repetitive IHF-binding palindromic) elements and demonstrate that IHF binds to them specifically. It is estimated that there are about 70 RIP elements in E. coli. Our analysis shows that the RIP elements are evenly distributed around the bacterial chromosome. The possible function of the RIP element is discussed.

Recent work indicates that regulation of the GCN4 gene of Saccharomyces cerevisiae by amino acid availability represents a gene-specific case of translational control by phosphorylation of eIF-2alpha. Four short open reading frames in the leader of GCN4 mRNA (uORFs) restrict the flow of scanning ribosomes from the cap site to the GCN4 initiation codon. When amino acids are abundant, ribosomes translate the first uORF and reinitiate at one of the remaining uORFs in the leader, after which they dissociate from the mRNA. Under conditions of amino acid starvation, many ribosomes which have translated uORF1 fail to reinitiate at uORFs 2-4 and utilize the GCN4 start codon instead. Failure to reinitiate at uORFs 2-4 in starved cells results from a reduction in the GTP-bound form of eIF-2 that delivers charged initiator tRNA(i)Met to the ribosome. When the levels of eIF-2.GTP.Met-tRNA(i)Met ternary complexes are low, many ribosomes will not rebind this critical initiation factor following translation of uORF1 until after scanning past uORF4, but before reaching GCN4. Phosphorylation of eIF-2 by the protein kinase GCN2 decreases the concentration of eIF-2.GTP.Met-tRNA(i)Met complexes by inhibiting the guanine nucleotide exchange factor for eIF-2, which is the same mechanism utilized in mammalian cells to inhibit total protein synthesis by phosphorylation of eIF-2.

At least four of the genes and operons involved in galactose transport and metabolism have promoters containing similar regulatory sequences. These sequences are recognized by at least three regulators, Gal repressor (GalR), Gal isorepressor (GalS) and cAMP receptor protein (CRP), which modulate transcription from these promoters. The negative regulators, GalR and GalS, discriminate between utilization of the high-affinity (regulated by GalS) and low-affinity (regulated by GalR) transport systems, and modulate the expression of genes for galactose metabolism in an overlapping fashion. GalS is itself autogenously regulated and CRP dependent, while the gene for GalR is constitutive. The gal operon encoding the enzymes for galactose metabolism has two promoters regulated by CRP in opposite ways; one (P1) is stimulated and the other (P2) inhibited by CRP. Both promoters are strongly repressed by GalR but weakly by GalS. All but one of the constituent promoters of the gal regulon have two operators. The gal regulon has the potential to coordinate galactose metabolism and transport in a highly efficient manner, under a wide variety of conditions of galactose availability.

With L1210 murine leukemia cells an IC50 value for cell proliferation of 20 pm was obtained, and an increase in the mitotic index concordant with the decrease in cell number was observed. Kangaroo rat kidney PtK1 cells were examined by indirect immunofluorescence with a spongistatin 1 concentration that caused 50% reduction in cellular protein (0.3 nm) and with a 10-fold higher concentration. These cells displayed mitotic and nuclear aberrations at both concentrations, and intracellular microtubules were reduced in number at the lower concentration and disappeared at the higher. Similar changes in PtK1 cells were observed after treatment with equivalent toxic concentrations of the antimitotic agents colchicine, vinblastine, halichondrin B, and dolastatin 10. Spongistatin 1 inhibited the glutamate-induced polymerization of purified tubulin (IC50 value of 3.6 muM versus 2.1 muM for dolastatin 10 and vinblastine and 5.2 muM for halichondrin B). Spongistatin 1 had no effect on the binding of colchicine to tubulin, but it was a potent inhibitor of the binding of vinblastine and GTP to tubulin. In initial experiments with 5 muM tubulin and 5 Am vinblastine, spongistatin 1 and dolastatin 10 both had IC50 values of 2 muM, whereas halichondrin B had an IC50 value of 5 muM. Spongistatin 1 thus represents a new member of the group of complex natural products that inhibit mitosis by binding in the Vinca alkaloid domain of tubulin.

Intoplicine induced both topoisomerase I- and II-mediated DNA strand breaks, using purified topoisomerases. The topoisomerase cleavage site patterns induced by intoplicine were unique, relative to those of camptothecin, 4'-(9-acridinylamino)methanesulfon-m-anisidide (m-AMSA), and other known topoisomerase inhibitors. Both topoisomerase I- and II-induced DNA breaks decreased at drug concentrations higher than 1 muM, which is consistent with the DNA-intercalating activity of intoplicine. DNA damage was investigated in KB cells in culture by using alkaline elution. Intoplicine induced single-strand breaks (SSB) in a bell-shaped manner with respect to drug concentration (maximum frequency at 1 muM almost-equal-to 220 rad-equivalents). SSB formation was fast, whereas reversal after drug removal was slow. Similar bell-shaped curves were obtained for DNA double-strand breaks (DSB) and DNA-protein cross-links. SSB and DNA-protein cross-link frequencies were approximately equal, and no protein-free breaks were detectable, indicating the protein concealment of the breaks, as expected for topoisomerase inhibition. Comparison of SSB and DSB frequencies indicated that intoplicine produced a significant amount of SSB not related to DSB, which is consistent with concomitant inhibition of both DNA topoisomerases I and II in cells. Data derived from resistant cell lines indicated that multidrug-resistant cells were cross-resistant to intoplicine but that m-AMSA- and camptothecin-resistant cells were sensitive to intoplicine. Hence, intoplicine might circumvent topoisomerase I-mediated and topoisomerase II-mediated resistance by poisoning both enzymes simultaneously.

Recent studies show two subtypes of receptors; a gastrin-releasing peptide (GRP) receptor subtype and a neuromedin B (NMB) receptor subtype exist. In contrast to the GRP receptor, no antagonists exist for the NMB receptor. In the present study we report that certain somatostatin (SS) octapeptide analogues function as selective NMB receptor antagonists. The most potent analogue, D-Nal-Cys-Tyr-D-Trp-Lys-Val-Cys-Nal-NH2, inhibited binding of I-125-[D-Tyr(o)]NMB to NMB receptor-transfected 3T3 cells and C6 cells. This analogue had 100-fold lower affinity for GRP receptors. Structure-function studies were performed by synthesizing 18 structurally related SS octapeptide analogues; each of these analogues, but not native SS-1 4 or SS-28, also inhibited binding to NMB receptors. The stereochemistry at positions 1, 2, 7, and 8, the hydrophobicity and ring size of the substitution in positions 1, 3, and 4, and the basicity of the group in position 5 were all important in determining NMB receptor affinity. No SS octapeptide analogue increased [H-3]inositol phosphates in NMB receptor-transfected cells; however, each analogue inhibited NMB-stimulated increases. The most potent analogue, D-Nal-Cys-Tyr-D-Trp-Lys-Val-Cys-Nal-NH2, caused a parallel rightward shift of the NMB dose-response curve, the Schild plot slope was not significantly different from unity, and the affinity was 230 nm. SS octapeptide analogues also interacted with SS receptors and mu-opioid receptors; however, there was no correlation between the affinities of the analogues for these receptors and their affinities for NMB receptors, demonstrating that these activities can be separated. The results demonstrate for the first time a class of antagonists with >100-fold selectivity for NMB versus GRP receptors. Because the structural requirements for determining NMB, SS, and mu-opioid receptor activity differ, it is likely that highly selective, specific, high affinity NMB receptor antagonists can now be developed that will be useful in defining the role of NMB in various physiological processes.

However, evidence has been accumulating that ethanol can affect the function of neurotransmitter-gated ion channels. Extracellular ATP has recently been reported to produce excitatory actions in the peripheral and central nervous systems by activating ligand-gated ion channels. We studied the effect of ethanol on membrane ion current activated by extracellular ATP in isolated bullfrog dorsal root ganglion neurons, by means of the whole-cell patch-clamp technique. The amplitude of the ATP-activated current was decreased by ethanol in a concentration-dependent manner over the range of 3-500 mm. The average inhibition of 1 mum ATP-activated current by 100 mM ethanol was 64 +/- 3%, and the concentration of ethanol that produced 50% inhibition was 68 mm. Ethanol inhibition of ATP-activated current was not dependent on membrane potential from -80 to +40 mV, and ethanol did not change the reversal potential of ATP-activated current. Ethanol (100 or 400 mm) shifted the ATP concentration-response curve to the right, increasing the EC50 for ATP from 3.0 mum to 6.0 mum or 22.3 mum, respectively, but did not reduce the maximal response to ATP. The results suggest that ethanol inhibits ATP-activated current by increasing the apparent dissociation constant for the ATP receptor.

There is evidence that the animals experience both abnormal spontaneous pain and abnormal evoked pains (allodynia and hyperalgesia). Experimental analyses of these models have demonstrated potential pathophysiologic mechanisms in both the peripheral and central nervous systems; it is likely that the model neuropathic pain syndromes are due to several different mechanisms. One line of evidence suggests that these pain states gradually become centralized due to an excitotoxic effect on spinal cord dorsal horn inhibitory interneurons. The role of the sympathetic nervous system appears to vary, depending on the type of nerve injury and the temporal evolution of the syndrome. There is evidence indicating that the abnormality of cutaneous temperature regulation that often accompanies painful peripheral neuropathy is not necessarily due to the activity of sympathetic vasomotor efferents.

Mutations in these genes resulting in mutator or antimutator phenotypes provide important tools to understand the mechanisms by which mutations occur. One way to isolate such strains is the use of papillation assays. We used one such assay based on the reversion of the galK2 allele in cells grown on MacConkey-Gal plates. Here, we describe the identification of the galK2 mutation and its possible reversion pathways, and the characterization of 7 mutators isolated using this system. 1 mutator resided in dnaE and 6 in dnaQ. Sequencing of the galK2 allele revealed a G . C --> T . A transversion at base pair 571 that changed a glu codon (GAA) to a stop codon (TAA). The analysis of 319 revertants showed that a Gal+ phenotype can be achieved by A . T --> G . C transition, A . T --> T . A transversion and A . T --> C . G transversion. We characterized the mutator phenotypes of the newly isolated mutators by determining (i) their mutation frequencies to resistance to rifampicin and nalidixic acid in both wild-type and mutL backgrounds, (ii) their temperature sensitivity and medium dependence and (iii) their mutational specificity (by analyzing the nature of galK revertants). Based on the genomic locations of their mutations, specificity of reversion pathways and magnitude of mutator effects, the mutators can be grouped into 3 classes. These classes may represent different mutational mechanisms that include defective base insertion, defective proofreading and interference with the postreplicative mismatch-repair system.

Thus, we studied LH pulsatile secretory pattern in a group of 29 males suffering from CH. Ten of them were studied longitudinally, while 19 were studied cross-sectionally only during active (n=9) or attack free (n=10) phases. Nine healthy, age-matched males were studied as reference group. All subjects underwent a pulsatility study of 6 hours, sampling every 15 minutes. CH patients resulted to have a lower LH pulsatile release both during active (3.6+/-0.9 peaks/6h, p<0.0001) and attack free (4.1+/-0.9 peaks/6h, p<0.004) phases than normal males (5.2+/-0.6 peaks/6h). When longitudinally studied, CH patients (n=10) showed lower LH secretory episodes during the active than during the attack free phase (3.3+/-0.9 and 4.1+/-0.7 peaks/6h, p<0.05). Testosterone plasma levels did not differ between active and free phases (4.3+/-1 and 4.7+/-0.8 ng/ml, respectively), while, in patients they were significantly lower than in controls (6.8+/-0.9 ng/ml, p<0.01)). These data demonstrate an impaired function of the hypothalamo-pituitary axis possibly due to an overactivity of the opioid neuromodulation. C1 UNIV CTR ADAPT DISORDERS & HEADACHE,PAVIA,ITALY.

In many GD3 patients, progressive myoclonus and dementia dominate the illness, with death secondary to progressive CNS disease. We have designated this group as GD3a. We studied 14 children with Gaucher's disease, isolated horizontal supranuclear gaze palsy, and aggressive systemic disease, and designated this group as GD3b. In comparison with 13 children with type 1 non-neuronopathic Gaucher's disease, the GD3b children presented earlier, and were shorter, underweight, and more prone to cardiopulmonary, hepatic, and skeletal complications. One-half of the children died in childhood or adolescence of systemic complications. Patients with at least one copy of the mutation that causes substitution of asparagine for serine at amino acid 370 of glucocerebrosidase did not develop neurologic signs. Patients homoallelic for the mutation causing substitution of leucine for proline at position 444 had severe systemic disease; neurologic signs were frequently, but not invariably, present. Early diagnosis and timely enzyme replacement therapy promise to improve the prognosis in GD3b. C1 NINCDS,DMNB,BLDG 10,ROOM 3D03,9000 ROCKVILLE PIKE,BETHESDA,MD 20892. NIDOCD,AUDIOL SECT,BETHESDA,MD.

Factors affecting the penetrance of the ITD gene have not yet been identified. The present study used four published series of cases to test specific hypotheses regarding factors that could affect the expression of ITD. Among the combined 253 families, transmission of ITD did not depend on either the sex of the affected offspring or that of the transmitting parent. Furthermore, neither the specific type of dystonia manifested, the site at which clinical signs of dystonia first appeared, nor age of onset differed significantly as a function of the gender of the transmitting parent. However, in familial cases of later onset (age greater-than-or-equal-to 20 years), nearly all involved a transmitting mother. There is evidence for consistency of age of onset within the subset of Jewish families. Although anticipation effects are apparent, sampling bias cannot be ruled out.

(J. Neurosci. 8, 4159-4167, 1988 [26]), hippocampectomized monkeys were found to be impaired on a task in which they were required to remember the spatial positions of trial-unique objects overlying two of the wells in a three-well test tray. There were two types of trial in the task. One type (object-place) required memory for the conjunction of object quality and object location, whereas the other (place only) required memory only for the location of the objects, i.e. independent of object quality. The hippocampectomized monkeys performed at near chance levels on both types of trials. The present study sought to determine whether the poor performance of the hippocampectomized monkeys on the place-only trials, which closely resembled spatial delayed response (an ability that is unaffected by hippocampectomy when similarly short delays are used), could have been due to interference from the simultaneous training they had received on the object-place trials. To this end, we examined the effect of hippocampal removals on performance of the ''place-only'' trial type when that was the only training given. The hippocampectomized monkeys in the present study were found to be just as severely impaired as those in the earlier study, thus ruling out the possible explanation outlined above. Since performance on this modified version of spatial delayed response, unlike performance on the classical version with the same delay, is critically dependent on the hippocampus, it appears that monkeys with hippocampectomy can remember one place after a short delay but not two.

In the present study, we examined the expression of 110,000 mol.wt laminin-binding protein in brains of adult mice, rats, and non-human primates. Essentially identical immunoreactivities were observed across species with distinct staining of cortical pyramidal neurons with apical dendrites, cerebellar basket cell axons, hippocampal mossy fibers, and fine labeling of processes throughout the brain. Colocalization of immunoreactivities to 110,000 mol.wt laminin-binding protein and to laminin in neurons of the adult rat brain was observed. Electron microscopy demonstrated that 110,000 mol.wt laminin-binding protein-like immunoreactivity is intracellular and is possibly associated with the neuronal cytoskeleton. Western blot analysis revealed that anti-110,000 mol.wt laminin-binding protein also recognizes a 140,000 mol.wt protein in the pellet, in addition to the 110,000 mol.wt protein in the Triton soluble extract. Antibody fractions specific to the two reactive protein species (110,000 mol.wt and 140,000 mol.wt) exhibited cross-reactivity on immunoblots and revealed similar immunohistochemical staining in adult brain. Results suggest a significant interaction between laminin-like molecules and 110,000 mol.wt laminin-binding protein-like molecules in normal brain function, in response to CNS injury and possibly in the pathogenesis of Alzheimer's disease.

Fourteen of the 15 tumors had one or more clonal mutations. Forty one mutations were found in the second exon; only one occurred in the third exon. Seven tumors had mutations that clustered in a region spanning amino acids 38-63. Four of these possessed mutations that altered prolines at positions 57 (3), 60 (1), and 63 (1). Seven tumors were mutated in the central portions of the second exon. These occurred at position 95 (2), position 115 (2), position 137 (1), and position 138 (3). Analysis of the published sequences from five lymphoma cell lines and one primary tumor showed a similar clustering of mutations, with all six having mutations in codons between positions 38-63. The regions where mutations occurred have been associated with a variety of properties, including transcriptional activation and cellular transformation. The number and location of mutations showed no correlation with either chromosome 8 or chromosome 14 breakpoints or with the Epstein-Bar virus positivity of the tumors. This unexpected, frequent occurrence of clustered mutations in the second exon of the MYC gene suggests a rote for the mutated MYC proteins in the pathogenesis of Burkitt's lymphoma, possibly through altered interactions of this domain with other cellular factors.

Two monkeys performed a noxious thermal detection task and the time to detection of small increases in heat served as a measure of the perceived intensity of pain. ST-91 microinjected into the MDH (1.0, 3.0, 10.0 and 30.0 mug/0.4 mul) produced dose-dependent increases in detection time to graded temperature increases (0.4-1.0-degrees-C) from a noxious 46-degrees-C base line. These dose-dependent effects were attenuated by the systemic administration of the alpha2-adrenoceptor antagonist, idazoxan (2.0 mg/kg, i.m.), but not by the alpha1-adrenoceptor antagonist, prazosin (0.5 mg/kg, i.m.) or the opioid-receptor antagonist, naloxone (0.5 mg/kg, i.m.). The effect of ST-91 on detection latency of thermal stimuli was not the result of alterations in attentional, motivational or motoric aspects of the monkeys' behavior, because detection of visual stimuli and non-noxious temperature coolings (36.0-34.5-degrees-C) in a similar paradigm were not consistently altered. Microinjection of morphine (3.0 mg) into the MDH also increased detection latency of the noxious heat stimuli. Systemic administration of the opioid-receptor antagonist, naloxone (0.5 mg/kg), and the alpha2-adrenoceptor antagonist, idazoxan (2.0 mg/kg, i.m.) attenuated these effects of morphine. In a separate experiment, morphine (5.0 mug) microinjected into the MDH induced facial scratching behavior. Idazoxan (2.0 mg/kg) was effective at attenuating this scratching behavior. We have thus shown participation of MDH alpha2-adrenoceptors in the process underlying the perception of the intensity of noxious thermal stimulation in monkeys. Further, opioid and noradrenergic systems interacted in the noxious heat detection paradigm and a paradigm where facial scratching behavior was studied.

It is now generally accepted that the phenomenon of tolerance is required to protect on individual from potentially autoreactive cells. Recent experiments have independently shown that parasite infection2 or interleukin 2 (IL-2)3,4 can reverse an established T-cell tolerance in vivo, Breaking T-cell tolerance restores the capacity of T cells to be stimulated by their specific antigen2 and, in the case of a self-antigen, may be followed by autoimmune disease3,4. In this review, Martin Rocken and Ethan Shevach briefly describe the potential pathways for generating T-cell tolerance in vivo, and focus on recently described mechanisms by which parasitic infections may circumvent or abrogate the tolerant state.

The gene therapy trial for ADA deficiency SCID has demonstrated that long term stable expression of exogenous genes can be achieved in human T lymphocytes using retroviral vectors for ex vivo treatment and that significant immune reconstitution can be achieved in these patients following periodic infusions with ADA gene-corrected autologous T cells. Newer clinical applications include the insertion of genes into CD34 enriched stem cell populations, the testing of autologous tumor vaccines employing cytokine gene-modified tumor cells and the direct transfer of the herpes thymidine kinase gene into brain tumors in situ in order to render those tumors sensitive to treatment with the ordinarily non-cytotoxic drug ganciclovir.

Both are potentially amenable to therapeutic intervention by gene therapy, in which the relevant gene is used to modify cells of the affected individual. Although the gene therapy strategies for these diseases are conceptually quite different, a promising approach for both is the in vivo administration of a recombinant replication deficient adenovirus vector containing a normal copy of the abnormal gene. If the goal is to express the normal extracellular anti-protease alpha1AT, the route of administration could be directly into the lung, liver or vascular endothelium. If the goal is to express the normal transmembrane protein defective in CF epithelial cells, the new gene will need to be delivered directly to the affected cells. The feasibility of these approaches has been demonstrated in vitro and in vivo in experimental animals. RP ROSENFELD, MA (reprint author), NHLBI,PULM BRANCH,BETHESDA,MD 20892, USA.

The informational cartoon illustrated how scald injuries can be prevented by adjusting the water heater thermostal. Self-efficacy, intention, knowledge, attitude and social desirability were measured Days were the randomization units. Over a 2-week period, five clinic days were randomly allocated to control and five to the intervention condition. During the control days, mothers in the pediatric department received only a posttest. During the intervention days mothers received the informational cartoon and posttest. Significant posttest differences between groups were found for self-efficacy (P < 0.004), intention (P < 0.001), knowledge (P < 0.001) and attitude (P < 0.03).

Quantitative PCR analysis was then employed to examine the interindividual variability of both CYP1A1 and CYP1A2 mRNAs in human liver. Hepatic content of CYP1A2 mRNA correlated significantly with levels of CYP1A2 protein as analysed by immunoblot analysis (r = 0.58; p < 0.01). CYP1A2 mRNA content varied >40-fold among individuals while CYP1A1 content varied >20-fold. CYP1A2 mRNA was higher than CYP1A1 mRNA (approximately two to 30-fold) in livers of different individuals. The individual with the highest CYP1A1 and CYP1A2 mRNA amounts was a current smoker, but mRNA expression in two other smokers was within the range observed among nonsmokers. The expression of the two CYP1A mRNAs correlated highly (r = 0. 72; p < 0.0005) when smokers were included, but the correlation was less significant (r = 0.62; p < 0.05) in nonsmokers. We amplified a full-length CYP1A2 cDNA clone by PCR from a liver which expressed extremely low amounts of CYP1A2 protein. Sequence analysis indicated that exon 4 was missing in this clone, but no other sequence changes were found. PCR analysis demonstrated that both the normally spliced mRNA and abnormally spliced mRNA could be detected in all human livers examined, but the normally spliced mRNA was more abundant than the splice variant. Therefore, sequence changes in the coding region of CYP1A2 did not account for the poor expression of CYP1A2 in this individual. C1 NIEHS,BIOCHEM RISK ANAL LAB,POB 12233,RES TRIANGLE PK,NC 27709.

Fifty-nine percent of the overall variation in acetylation activity was explained by genotype (p < 0.0001). The remaining variation in acetylation was not associated with dapsone N-hydroxylation activity, age, current smoking status, or weight in the study population, or within any genotype subgroup. Although acetylation activity in the homozygous mutant group did not overlap with the other genotype categories, there was moderate overlap in acetylation between the heterozygous mutant and wildtype groups, and substantial variation in acetylation within them. Considering all subjects with the identical NAT2 genotype as phenotypically similar and all subjects with differing NAT2 genotypes as phenotypically distinct may result in misclassification of metabolic risk factors in epidemiological investigations. As such, it would seem prudent, where possible, to collect both acetylation phenotype and NAT2 genotype data, since the advantages and limitations of these two sources of information complement, and serve to assess the accuracy of each other.

The CYP2D6 alleles from two subjects having a high MR, characteristic of slower rates of sparteine metabolism, were cloned in lambdaEMBL3 and subjected to sequence analysis. One individual possessed a CYP2D6B allele, typically found in Caucasians, that is inactive due to an altered 3' splice recognition site and other potentially disruptive mutations. The second allele from this individual was identical to the wild type normal Caucasian CYP2D6 allele except for C188T and G4268C base differences in exons 1 and 9, respectively, that result in P34S and S486T amino acid substitutions. This allele was designated CYP2D6J. The second individual possessed two CYP2D6J alleles. PCR assays were performed to detect this allele and other alleles from a group of subjects exhibiting low rates of sparteine metabolism, i.e. with MRs > 1.5. Eleven CYP2D6J alleles were detected in 14 subjects exhibiting low rates of metabolism and including four individuals who were homozygous for this variant and had very low rates of sparteine metabolism (MRs > 2.5). In contrast, only two CYP2D6J alleles were found in 14 subjects having MRs of < 1.0. These data suggest that CYP2D6J encodes an enzyme having lower rates of sparteine metabolism.

Acute treatment with haloperidol or the combination of haloperidol and lithium significantly reduced IP basal cortical levels. Subacute (three days) treatment with lithium decreased the IP basal level in the frontal cortex. Chronic treatment with haloperidol (14 and 28 days) caused a significant attenuation of carbachol-sensitive IP accumulation in the frontal cortex and striatum and a significant decrease in norepinephrine (NE)-induced IP formation in the frontal cortex (14 and 28 days) and striatum (28 days). Lithium treatment for 14 days produced a significant reduction in the IP basal cortical value, and a significant reduction in cortical carbachol- and NE-induced IP formation was found after 28 days of lithium treatment. The combination of haloperidol and lithium for 28 days decreased the striatal carbachol- and cortical NE-induced IP accumulation and caused a significant increase in NE-sensitive IP formation in the striatum at 14 days. Valproate treatment for 28 days was associated with a significant attenuation in striatal agonist-stimulated IP formation. Therefore, three drugs with different specificities for primary neurotransmitters may have common effects on second-messenger systems.

Both treatments are thought to be carcinogenic, but little is known about their interaction in the induction of skin cancer. Tumors induced in mice treated with both PUVA and UVB, either given sequentially or concurrently, seemed to be more antigenic as a group than tumors treated by PUVA alone, as determined by their lower frequency of growth when transplanted into naive mice. In this study, we treated C3H mice with a subcarcinogenic dose of UVB radiation for 4 weeks, followed by PUVA treatment for 41 weeks (sequential experiment) or with both UVB radiation (minimal carcinogenic dose) and PUVA for 41 weeks (concurrent experiment) and monitored the development of skin cancers. Although a few tumors appeared earlier in the groups treated with both UVB and PUVA in both experiments, no significant differences were observed in the rate of tumor development in mice treated with UVB and PUVA versus those treated with PUVA alone.

An oral 10 mg/kg dose of RU 486 or placebo was administered at midnight the second night of a 48-h hospital stay. Macronutrient and caloric intakes were calculated each day and a taste test of six commercial dairy products (fat content by weight < 0.5%, 2.0%, 3.3%, 10.5%, 18%, and 36%) was performed. Dairy products were judged for pleasantness, creaminess, and overall preference. Subjects were then asked to consume their favorite dairy product until sated. Urinary free cortisol (UFC) and plasma adrenocorticotropic hormone (ACTH), cortisol, insulin, and glucose were determined. Intake of a self-selected diet was recorded. As expected, in response to RU 486, UFC increased from 120 +/- 25 mug/24 h to 297 +/- 73 mug/24 h (p < 0.05) in obese men and from 81 +/- 10 mug/24 h to 357 +/- 109 mug/24 h (p < 0.05) in lean men. Plasma cortisol increased from 26.1 +/- 1.1 mug/dl to 31.8 +/- 1.0 mug/dl (p < 0.05) in obese men and from 26.1 +/- 1.7 mug/dl to 32.2 +/- 1.7 mug/dl (p < 0.05) in lean men. Plasma insulin was significantly higher in obese 24.6 +/- 3.2 muIU/ml than in lean men 12.8 +/- 1.1 muIU/ml (p = 0.0001) but was unaffected by RU 486. RU 486 did not decrease fat intake in either obese or lean men. However, in obese men UFC was significantly correlated with fat intake from the overall preferred product in the taste test (r = 0.84, p < 0.05) and with fat intake during the following 24 h.

Although RU 486 did not alter fat intake in obese or lean men, correlations between UFC and both measures of fat intake in obese men suggest that cortisol may play a role in the pathophysiology of obesity.

Using AVP-dependent flank-marking behavior as a bioassay, it was possible to verify that iodinated SAVP (I-SAVP) retains biological activity within the central nervous system, as the antagonist blocked the behavior. Furthermore, I-125-SAVP was used to localize specific V1 binding sites in the brain. The resulting binding was localized to discrete anatomical sites, and highly specific to V1-like receptors. While we confirmed previous findings using H-3-AVP in golden hamsters, we also identified binding in many areas previously unreported (e.g., arcuate and paraventricular nuclei of the hypothalamus, tenia tecta, posteromedial cortical nucleus of the amygdala, and zona incerta), suggesting that I-125-SAVP provides a greater level of resolution. In addition, specific binding was observed in the lateral septum, anterior hypothalamus, and midbrain central gray, areas that have previously been shown to trigger flank marking in response to AVP microinjection. The presence of AVP binding sites in limbic and mesencephalic areas involved in the regulation of flank marking suggests that this neuropeptide may play an important role as a neurotransmitter at multiple levels in the neural circuits controlling this behavior.

However, there was no significant change in the polyphosphorylated inositol phospholipids or inositol phosphates or in inositol phospholipid metabolism within 30 s of imposing the hyperosmotic stress. Maximum changes in phosphatidylinositol 4-monophosphate (PIP) metabolism were detected at 5 min, at which time the cells appeared adjust to the change in osmoticum. There was a 30% decrease in [H-3]inositol-labeled PIP. The specific activity of enzymes involved in the metabolism of the inositol phospholipids also changed. The plasma membrane phosphatidylinositol ( PI) kinase decreased 50% and PIP-phospholipase C (PIP-PLC) increased 60% compared with the control values after 5 min of hyperosmotic stress. The PIP-PLC activity recovered to control levels by 10 min; however, the PI kinase activity remained below the control value, suggesting that the cells had reached a new steady state with regard to PIP biosynthesis. If cells were pretreated with okadaic acid, the protein phosphatase 1 and 2A inhibitor, the differences in enzyme activity resulting from the hyperosmotic stress were no longer evident, suggesting that an okadaic acid-sensitive phosphatase was activated in response to hyperosmotic stress. Our work suggests that, in this system, PIP is not involved in the initial response to hyperosmotic stress but may be involved in the recovery phase.

Data were from 18 North American veterinary teaching hospitals. Patients diagnosed with laryngeal hemiplegia were identified. In order to determine the frequency of diagnosis, statistics were gathered for patient-years-at-risk. The independant risks of age, sex, and breed on the hospital prevalence were determined. Laryngeal hemiplegia was diagnosed in 2798 horses representing 29 breeds. The male risk compared with females (OR = 1) was 2.7. Laryngeal hemiplegia was diagnosed significantly more often in three breeds of draft horses, Thoroughbreds, and American Saddlebreds; and significantly less often in Arabians, Appaloosas, American Paints, and American QuarteT Horses. Standard bred horses and Tennessee Walking Horses were seen about as frequently as they were represented in the hospital population. Using the proportion of cases-to-population seen at 2-3 years of age as the standard reference point (OR = 1), Thoroughbreds showed a peak hospital prevalence at 2-3 years of age; thereafter their cause specific accession rate decreased. Other breeds, particularly the draft horses, showed an increasing rate of diagnosis over 3 years of age. The peak age of diagnosis for draft animals was 7-9 years; for the Standardbred and the American Quarter Horse, it was 4-6 years. C1 NCI,ENVIRONM EPIDEMIOL BRANCH,ROCKVILLE,MD 20892.

Capuchins were presented with an apparatus designed to accommodate the use of pounding tools to crack walnuts and the use of probing tools to loosen and extract the inner meat. Three capuchins used stones and sticks sequentially for these purposes. The capuchins' behavior was similar in form and function to behavior that has been reported for chimpanzees in analogous situations. These results provide further evidence of the extensive tool-using capabilities of capuchin monkeys and are consistent with a hypothesis of cross-species continuity in the skillful use of tools by primates.

All offspring born between 1985 and 1988 that survived to at least 1 year of age (n=75) were available for paternity testing. The exclusion of all but one of the potential fathers from paternity was possible in 70 cases (93%). Mating activities were recorded using ad lib. and focal female sampling techniques. The analysis of male mating effort was restricted to the most likely days of conception. Male rank correlated significantly with male mating success in all four breeding seasons and with male reproductive success in three of the four seasons. Mating success and reproductive success also showed a significant correlation, with the exception of one breeding season, in which the proportion of males per fertilizable female was especially high. Poor mating success was almost always associated with poor reproductive success, while good mating success was less predictive for a male's actual reproductive success. This was apparently a consequence of sperm competition, resulting from the promiscuous mating system. Male mating success is not necessarily an unreliable indicator for reproductive success, provided that sufficient sample sizes are available and that conception periods can be determined. Sperm competition and other factors may weaken the association, however. C1 UNIV BONN,INST ZOOL,ETHOL ABT,D-53115 BONN,GERMANY. NIH,CTR ANIM,COMPARAT ETHOL LAB,POOLESVILLE,MD 20837.

The individual alpha and beta subunits were monitored with specific antisera. In all cases, both subunits cosedimented, indicating that the subunits are likely complexed as heterotrimers. When extracted with Lubrol all of the G proteins sedimented with rates of about 4.5 S (consistent with heterotrimers) whereas digitonin extracted 60% of the G proteins with peaks at 11 S; 40% pelleted as larger structures. Digitonin-extracted G(i) was cross-linked by p-phenylenedimaleimide, yielding structures too large to enter polyacrylamide gels. No cross-linking of Lubrol-extracted G(i) occurred. Treatment of the membranes with guanosine 5'-[gamma-thio]triphosphate and Mg2+ yielded digitonin-extracted structures with peak sedimentation values of 8.5 S-i.e., comparable to that of purified G(o) in digitonin and considerably larger than the Lubrol-extracted 2S structures representing the separated alpha and betagamma subunits formed by the actions of guanosine 5'-[gamma-thio]triphosphate. It is concluded that the multimeric structures of G proteins in brain membranes are at least partially preserved in digitonin and that activation of these structures in membranes yields monomers of G proteins rather than the disaggregated products (alpha and betagamma complexes) observed in Lubrol. It is proposed that hormones and GTP affect the dynamic interplay between multimeric G proteins and receptors in a fashion analogous to the actions of ATP on the dynamic interactions between myosin and actin filaments. Signal transduction is mediated by activated monomers released from the multimers during the activation process.

Incomplete viral DNA (previously demonstrated to be associated with HIV-1 virions) is carried by HIV-1 virions into quiescent and activated PBLS, contributing to the formation of an early viral DNA pool in these cells. The viral DNA is subsequently completed but only extremely slowly and inefficiently in quiescent PBLs compared to that in stimulated PBLs. We find that this correlates with significantly lower levels of dNTP substrates in quiescent compared to activated PBLs. At these low dNTP concentrations, HIV-1 reverse transcriptase acts in a partially distributive manner. Increasing dNTP concentrations from the levels of quiescent PBLs to the levels of activated pBLs the processive action of reverse transcriptase, which in turn stimulates rapid and efficient formation of full-length DNA. Furthermore, hydroxyurea treatment of stimulated PBLs decreases the dNTP levels and the DNA synthesis rate to levels comparable to quiescent PBLs. Our data therefore indicate that low levels of dNTP may explain why HIV-1 DNA is synthesized slowly and inefficiently in quiescent PBLs and suggest that pharmacologic induction of low dNTP levels represents a therapeutic approach for inhibition of HIV-1 replication.

The molecules were deposited and imaged in aqueous electrolyte under potential control, a procedure that eliminated the problem of the substrate artifacts that had limited some previous STM studies. Experiments were carried out with two types of single-stranded molecules (11 and 20 bases long) and three types of double-stranded molecules (20 and 61 base pairs and 31 bases with 25 bases paired and 6-base ''sticky'' ends). The molecules lie along symmetry directions on the reconstructed (23 x square-root 3) gold surface, and length measurements indicate that they adopt simple base-stacked structures. The base stacking distances are, within experimental uncertainty, equal to the 0.33 nm measured for polymeric aggregates of stacked purines by direct imaging in identical conditions. The images show features consistent with helical structures. Double helices have a major-groove periodicity that is consistent with a 36-degrees twist. The single helices appear to be more tightly twisted. A simple tunneling model of STM contrast generates good agreement between measured and calculated images.

Highly degenerate oligonucleotides encoding two conserved regions were used in a PCR reaction to amplify cDNAs encoding each of the known ARF proteins and eight addition cDNA fragments encoding previously unreported human members of the ARF family. Additional sequences were obtained from yeast or fly libraries by using this technique. These oligonucleotides specifically amplify members of the ARF family but not the structurally related G protein alpha subunits or members of the other three subfamilies of the RAS superfamily. Fragments obtained by PCR were used to obtain full-length sequences encoding highly homologous ARF-like (ARL) gene products from human and Drosophila melanogaster libraries, termed ARL2 and Arl84F, respectively. The encoded proteins are each 184 amino acids long and am 76% identical, with 40-45% identity to human ARF1 and Drosophila arf-like (arl) proteins. These genes appear to be generally expressed in human tissues and during Drosophila development. The purified human ARL2 protein differed in several biochemical properties from human ARF proteins, including the complete absence of ARF activity. Thus, the ARF family of low molecular weight GTP-binding proteins includes at least 15 distinct but structurally conserved members, including both the functionally conserved ARF proteins and the functionally disparate ARL proteins. The latter proteins currently comprise two distinct gene products in Drosophila (arl and ARL84F) and one in man (ARL2).

We also examined 36 of these 50 carcinomas for expression of the cyclin D1 and retinoblastoma (RB) proteins by immunohistochemistry. We found a 3- to 10-fold amplification of the cyclin D1 gene in 16 of the 50 (32%) tumors and in two of the four cell lines. Cyclin D1 protein was overexpressed in 12 of 13 tumors and the two cell lines that showed gene amplification when compared to normal controls. Studies on RB protein expression indicated that 6 of the 36 (17%) tumor samples examined and one cell line did not show detectable expression of this protein. The tumors and cell lines that had cyclin D1 gene amplification and overexpression exhibited normal levels of expression of R.B protein. By contrast, the tumors and cell line that did not appear to express the RB protein did not show amplification of the cyclin D1 gene and expressed only low levels of the cyclin D1 protein (P = 0.03). These results suggest that the inhibitory effect of RB on cell cycle progression can be abrogated during tumor development either by loss of expression of the RB gene or by increased expression of the cyclin D1 gene.

These waters, originally placed uniformly about the protein, form clusters that hydrate every charged group throughout the entire simulation. Some atoms in charged groups are hydrated by two water layers while 37% of the protein surface remains uncovered. The locations of the 350 waters are consistent with those of crystallographic waters resolved by x-ray and neutron diffraction. Hydration by 350 waters at 300 K stabilizes the conformation of carboxymyoglobin measured by x-ray diffraction throughout the entire protein, halves the rate of torsional transitions, and promotes alternative conformations for surface atoms. The glass transition observed experimentally in hydrated myoglobin near 220 K is also seen in the simulations and correlates with an increase in the number of dihedral angles undergoing transitions.

G16alpha in membrane extracts of Sf9 cells activated phospholipase C-beta1 (PLC-beta1) in the presence of guanosine 5'-[gamma-thio]triphosphate; the system could not be activated by Al3+, Mg2+, and F-. The G16alpha in the cytosolic fraction of Sf9 cells did not stimulate PLC-beta1. Concurrent expression of the G-protein betagamma subunit complex increased the amount of G16alpha. in Sf9 cell membranes. The guanosine 5'-[gamma-thio]triphosphate-activated form of G16alpha was purified from cholate extracts of membranes from cells expressing G16alpha, and the G-protein beta2 and gamma2 subunits. G16alpha activated PLC-beta1, PLC-beta2, and PLC-beta3 in a manner essentially indistinguishable from that of G(qalpha). G16alpha-mediated activation of PLC-beta1 and PLC-beta3 greatly exceeded that of PLC-beta2. G16alpha did not activate PLC-gamma1 or PLC-delta1. Thus, two distantly related members of the G(qalpha) family, G(qalpha) and G16alpha, have the same ability to activate the known isoforms of PLC-beta.

Forty of the 94 relevant bases differ between the P1 and P7 parS sites, and the protein-site interactions show complete species specificity. A method was developed to predict which subset of the differing parS bases is responsible. When the four Pl bases thus identified were substituted into the P7 parS site, a complete switch to P1 specificity was observed. The P1-specific bases constitute two CG dinucleotide elements situated 66 bp apart. They lie within repeats of the TCGCCA sequence implicated in secondary contacts with the P1 ParB protein. The equivalent TC dinucleotides in the P7 site were found to be involved in P7 specificity. However, three other P7 bases can also contribute, including two in the heptamer repeats primarily responsible for ParB binding, and the P7-specific information shows some redundancy. The motifs containing the specificity dinucleotides and the primary ParB binding (heptamer) sites bear no obvious relationship of spacing or orientation to each other. For the ParB protein to contact both types of motif at the same time, the topology of the interaction must be complex.

Although dissociation is presumed to be a special state of consciousness manifested by state-dependent memory and physiology, the psychobiology of dissociation is poorly understood. In this study, we examined cerebrospinal fluid levels of the major monoamine metabolites and beta-endorphin in patients with eating disorders (11 with anorexia nervosa, 16 with bulimia nervosa), while they were acutely ill. Dissociative capacity was measured using the Dissociative Experiences Scale (DES). We provide evidence that neurochemical changes in dopaminergic, serotonergic, and opioid systems may be associated with the clinical expression of dissociation in patients with eating disorders during the acute phase of their illness. These preliminary results are compatible with previous studies of neurochemical disturbances in the eating disorders and suggest that future work in dissociation should specifically include examination of these neurobiologic systems.

Since Alzheimer's disease is the most common cause of dementia in geriatric patients, we investigated whether the cognitive decline observed in schizophrenia is the result of degenerative changes analogous to those characteristic of Alzheimer's disease. For this purpose, the number and distribution of senile plaques and neurofibrillary tangles were mapped in the hippocampi of 10 cognitively impaired schizophrenic patients, 10 patients with Alzheimer's disease, and IO patients with dementia not attributed to either schizophrenia or Alzheimer's disease. In Alzheimer's disease, degenerative changes invariably predominated in the CA1 subfield, subiculum, and proisocortex. By contrast, findings characteristic of Alzheimer's disease were virtually never observed in the hippocampi of schizophrenic and other cognitively impaired patients. In some patients with Alzheimer's disease, the presence of senile plaques in the molecular layer of the dentate gyrus suggested the existence of an underlying entorhinal cortex lesion. Similar dentate gyrus pathology was never found in any of the other patients. The authors conclude that cognitive impairment in schizophrenia is not the result of degenerative changes analogous to those found in Alzheimer's disease. C1 MED COLL GEORGIA,AUGUSTA,GA 30912.

Three methods for statistical analysis of regional ''subtraction'' data were used: absolute rCBF values, percent distribution values, and means adjusted for global CBF changes (covariance analysis). The absolute values had high variance, due to the combination of interindividual differences in global flow and intra-individual variation, and showed no statistically significant regional changes. This variation was greatly reduced by percent values and covariance analysis, which had quite similar outcomes. With both methods, significant increases of rCBF during the WCST as compared with the BAR were seen-in the right anterior dorsolateral prefrontal and left occipital cortices, and reduction of rCBF in the left pararolandic region. Moreover, significant correlations with performance were found in the medial regions of the frontal lobes, with opposite trends for the right and left hemisphere. The posterior dorsolateral prefrontal region showed a negative correlation with sensory-motor frequency, an index related to the task's difficulty. These results are consistent with previous findings using other rCBF techniques and confirm the statistical advantage of normalization and covariance methods, which yield practically identical results, at least in this analysis based on regions of interest.

We have assessed the potential clinical value of phenserine for cholinomimetic therapy of cognitive impairments associated with aging and Alzheimer's disease by evaluating its duration of in vivo activity against rat plasma acetylcholinesterase (AChE) and its effect on attenuating a scopolamine-induced impairment in learning performance of young rats in a shock-motivated 14-unit T-maze. Phenserine achieved maximum AChE inhibition of 73.5% at 5 min and maintained a high and relatively constant inhibition for more than 8 h. For analysis of effects on learning performance, 69, 3-month-old male Fischer-344 rats were pretrained in a straight runway to avoid electric footshock. On the following day, each animal received 15 trials in the 14-unit T-maze. Sixty minutes prior to the maze training, each rat received the first IP injection of either vehicle (Tween 80, ethanol and 0.9% NaCl) or phenserine at 1.5, 3.0, 4.0, 5.0, 7.5, or 10.0 mg/kg. Then 30 min prior to the training, each animal received a second IP injection of either 0.9% NaCl or scopolamine hydrochloride (0.75 mg/kg; SCOP). Compared to the vehicle-SCOP group, all but the 7.5 mg/kg dose of phenserine significantly ameliorated error performance, runtime, shock frequency and shock duration in SCOP-treated rats at the final block of three trials. Appearing to have a long effect and a wide therapeutic window, phenserine deserves further study as a cognitive enhancer.

During dose finding, performance on a verbal memory task improved with an inverted U-shaped relation to dose. Six of nine subjects were classified as responders. During blinded, placebo-controlled, individualized optimal dosing for 5 days, verbal memory again improved in five of six responders but not in any non-responder. No adverse drug effects occurred. Arecoline, and possibly other cholinergic agonists, can safely improve memory in Alzheimer's disease at doses much lower than previously studied.

Benzodiazepine (BZ) treated normal subjects demonstrate similar, marked impairments in episodic memory, but in addition, BZ also induces sedation and inattention. Thus, the amnestic effects of BZ may be secondary to drug-induced sedation. However, when subjects were pretreated with the specific BZ receptor antagonist, flumazenil, the sedative and attentional effects of diazepam were blocked, but a marked impairment in episodic memory still occurred. This demonstrates that, using neuropharmacological, methods, it is possible to produce a dissociation of memory impairment from inattention and sedation. Such distinct patterns of cognitive dysfunction may serve as models for clinical cognitive syndromes. C1 UNIV MARYLAND,SCH MED,DEPT PSYCHIAT,MARYLAND PSYCHIAT RES CTR,BALTIMORE,MD 21201.

The IV bolus administration of 3 mg/kg cocaine resulted in plasma levels of 1276 +/- 53 ng/ml cocaine at 0.5 min following its injection and the levels then rapidly declined to 768 +/- 110 ng/ml by 2 min. Thereafter, the decline of plasma cocaine levels was relatively slow. Plasma benzoylecgonine levels were similar at 0.5 and 2 min following cocaine injection but increased gradually over the next 25 min. Pretreatment with the norepinephrine-selective ve uptake inhibitors desipramine and nisoxetine, the serotonin-selective uptake inhibitor fluoxetine or the dopamine-selective uptake inhibitor GBR 12909 all enhanced plasma levels of cocaine after a 3 mg/kg IV bolus injection at 0.5, but not at 5 min after injection. The enhancement of plasma cocaine levels by GBR 12909 was of greater magnitude than that produced by desipramine, nisoxetine or fluoxetine. These agents, with the exception of the high dose (10 mg/kg) of GBR 12909, did not significantly alter plasma levels of benzoylecgonine measured at either 0.5 or 5 min following cocaine injection. These results indicate that monoamine uptake inhibitors can alter or interfere with the pharmacokinetics of cocaine and that this interaction is not due to a change in the biotransformation of cocaine. It is suggested that the central monoamine uptake sites serving as rapid distribution sites for cocaine may play a role in this pharmacokinetic interaction.

MATERIALS AND METHODS: Five patients with JPAs who had undergone structural imaging and fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) were studied. Normalized glucose utilization rates (GURs) in the tumor were compared with GURs in histopathologically verified low-grade astrocytomas and high-grade tumors. RESULTS: All JPAs enhanced markedly after administration of contrast medium. Their glucose metabolism was significantly (P < .001) higher than that of low-grade astrocytomas and was similar to that of anaplastic astrocytomas. All patients with JPAs were in stable condition and showed no evidence of disease progression despite contrast enhancement and high tumoral glucose metabolism. CONCLUSION: The paradoxical FDG PET findings and enhancement at structural imaging might reflect the unusual vascularity of pilocytic tumors, and the increased GUR might be related to expression of the glucose transporter.

A polarized light beam is made to pass through a liquid sample two or more times before detection by reflecting the beam from the surface of the sample container. The optical activity of the sample is measured using a differential polarization detector. Our results show that, for certain initial polarization states and angular orientations of the beam with respect to the glass interfaces, high sensitivity to changes in the concentration of the sample can be achieved. Results of a theoretical analysis of the technique were confirmed by experiments in which optical rotation of glucose in water was measured using a simple apparatus that employs a light-emitting diode source. Glucose sensing in vivo and on-line monitoring of industrial processes using integrated optoelectronic sensors are discussed as potential applications.

The HR2247 has a spectral range of 160-650 nm, a frequency response to 1 GHz and is inexpensive. A gate mesh covers part of the photocathode surface. Internal mixing is accomplished by applying a rf signal to the gate mesh. A fiber-optic/objective assembly mounted on an X-Y stage scans the position of the incident laser beam on the mesh. In order to evaluate the suitability of the HR2247 for practical fluorescence and imaging experiments, the photocathode surface was mapped at 41, 205, 410, 615, and 820 MHz modulation frequencies for variations in phase and modulation. The mixed signal at any point on the gate mesh can be optimized by adjusting the potential at the gate mesh. RP WILLIAMSON, CK (reprint author), NHLBI,CELL BIOL LAB,BETHESDA,MD 20892, USA.

Values of the model's parameters were varied to reflect alternative mechanisms of expression of the protein. These assumptions had dramatic effects on the computed response to a bolus dose of the xenobiotic ligand. If all processes in the model exhibit hyperbolic kinetics, the dose-response curves can appear sigmoidal but actually be linear with a positive slope at low doses. The slope of the curve only approached zero at low dose, indicative of a threshold for response, if binding of the xenobiotic ligand to the receptor exhibited positive cooperativity (ligand binding at one site increases the affinity for ligand at another binding site on the receptor). Positive cooperativity in the rate-limiting step of protein synthesis produced dose-response curves which were ''U-shaped'' at low doses, also indicative of a threshold. Positive cooperativity in the metabolism of the xenobiotic ligand produced dose-response curves that increased more rapidly than linearly with increasing dose. The model illustrates the fact that response cannot be predicted from qualitative mechanistic arguments alone; any assessment of risk to health from xenobiotic chemicals must be based on a detailed quantitative examination of the kinetic behavior of each chemical species individually.

This virus was shown to bind to blood-group P antigen, as measured by hemagglutination. Erythrocytes lacking P antigen were not agglutinated with B19. Purified P antigen (globoside) blocked the binding of the virus to erythroid cells and the infectivity of the virus in a hematopoietic colony assay. Target cells were protected from infection by preincubation with monoclonal antibody to globoside. Knowledge of a parvovirus receptor has implications for understanding the pathogenesis of parvovirus infections and for the use of parvoviruses in gene therapy.

It is shown that the dynamics of the slow variables is approximated by a two-dimensional averaged system. If the oscillators.have similar frequencies at a fixed point of the averaged system, then the relative phase behavior of the oscillators is approximated by a three-dimensional flow. Under the stronger assumption that the oscillators themselves are similar and that the fixed point of the averaged system is symmetric, hyperbolic, and stable, a further reduction to a flow on a cylinder is possible. This cylinder flow is computed for an example in which phase entrainment, relative phase oscillations, and bidirectional wrapping of relative phase are demonstrated.

More precisely, we explored whether schizophrenic patients are more likely than other psychotic patients to work in environments with a low potential for arousal (low complexity environments) in the last full-time job that preceded their hospitalization. All first admissions with psychotic symptoms to 15 hospitals providing inpatient psychiatric services in the Baltimore-Washington area were surveyed during a 6-year period. Patients diagnosed with schizophrenia were compared to patients diagnosed with bipolar disorder and other psychotic disorders to evaluate the suspected association. Study participants were assessed with a modified version of the Diagnostic Interview Schedule. Standard survey questions were used to assess occupational background. A measure based on the dictionary of occupational titles (DOT) was used to estimate the degree of complexity to which patients had been exposed in their last full-time occupation. Data were analyzed using multinomial logistic regression. After adjustment for age, gender, marital status, unemployment, socioeconomic status, hospital type, and physical demands and hazards on the job, patients with schizophrenia were more likely to have been working in low complexity environments in their last full-time jobs (e.g., janitors, gardeners, guards) than patients with bipolar disorder or with other psychotic disorders. Alternative explanations and potential implications regarding which work environments might be best suited to the social behavior of patients with schizophrenia are examined.

An approach is presented by which an alarm is determined as either confirmed or rejected according to data observed subsequent to the alarm. The suggested procedure is expected to weed out a substantial proportion (say about 75 per cent) of the false alarms at the expense of some delay in detecting a true alarm.

In studies with a baboon (Papio anubis), [C-11]WIN 35,428 accumulated in brain regions containing dopamine transporters, i.e., the striata. This accumulation was partially blocked by prior administration of (-)cocaine (4 mg/kg, i.v.). Placement of a unilateral lesion of dopamine-containing nerve terminals with MPTP resulted in a unilateral reduction in [C-11]WIN 35,428 accumulation in the striatum on the side of the lesion. Imaging of D2 dopamine receptors with [C-11]NMSP in the same MPTP-treated animals showed much less reduction in the postsynaptic D2 dopamine receptors as compared to the much larger reduction in the dopamine transporters labeled with [C-11]WIN 35,428. A total of ten normal human volunteers (five males and five females) with ages ranging from 19 to 81 years were studied. The caudate/cerebellar and putamen/cerebellar ratios ranged from 4.4 to 5.7 90 min after injection of the tracer. Preliminary kinetic modeling with arterial plasma sampling resulted in an average binding potential (k3/k4) of 4.98 in the caudate nucleus and 5.13 in putamen. To demonstrate in vivo blockade with dopamine reuptake inhibitors, two subjects received prior oral doses of 6 mg mazindol. Subject 5 had significant reductions of 29% in the caudate/cerebellar ratio at 90 min, 35% in the putamen/cerebellar ratio at 90 min, 45% in the caudate k3/k4 ratio from 6.7 to 3.7, and 46% in the putamen k3/k4 from 4.7 to 2.5. Subject 8 had significant reductions of 20% in both the caudate/cerebellar ratio and the putamen/cerebellar ratio at 90 min. During the human PET studies, a number of neuropsychological tests and physiological measurements were performed. No significant changes were found after administration of the [C-11]WIN 35,428 alone. Taken together, these data indicate that [C-11]WIN 35,428 is a promising radioligand for future studies of neuropsychiatric disorders that involve the dopamine transporter site.

An enantioselective synthesis of substituted benzilic acids was achieved using 8-phenylmenthol as the chiral auxiliary. Grignard addition to the si face of 8-phenylmenthyl benzoylformate 7 proceeded with high selectivity. The results of the chiral induction support assignments of the chirality of benzilic acids previously resolved by crystallization. The method was used to synthesize (R)-quinuclidinyl-(R)-(4-iodo)benzilate, which proved identical to an authentic sample. In addition, the method allows the preparation of (R)- and (S)-fluoroethyl benzilic acids in a stereoselective manner.

The oocytes were evaluated for: nuclear maturation after 48 hours of culture (in vitro maturation, IVM); fertilization and cleavage 24 to 30 hours postinsemination (in vitro fertilization, IVF); and early embryo development 48 hours postinsemination. Maturation rates were similar (P>0.05) for WAY + BSA (29.4%), MEM + BSA (46.7%) and MEM + PVA (43.3%), but were different (P<0.05) from the other treatments (range, WAY + FCS, 9.6% to WAY + PVA, 14.9%). Fertilization and cleavage rates were also similar (P>0.05) for WAY + BSA (51.4%, 30.5%), MEM + BSA (45.8%, 40.1%) and MEM + PVA (56.1%, 37.4%) and were greater (P<0.05) than all other treatments. These IVM/IVF oocytes were capable of culturing beyond 2-cells, with the highest proportion of 4- and 8- cell embryos forming in WAY and MEM media in the presence of BSA or in MEM medium containing PVA. In the domestic cat IVM/IVF system: both the type of culture medium and protein supplement influence the proportion of oocytes reaching Metaphase II; the type of protein supplement has a more significant (P<0.05) impact than medium on fertilization, cleavage and early embryo development; and nuclear maturation and fertilization in vitro can proceed in this species in the absence of supplementary protein.

Since the lung is the most common site of infection in those who progress to AIDS it is rational to consider whether it is possible to safely augment glutathione levels in the epithelial lining fluid of HIV seropositive individuals, thus potentially improving local host defence. Methods-Purified reduced glutathione was delivered by aerosol to HIV seropositive individuals (n = 14) and the glutathione levels in lung epithelial lining fluid were compared before and at one, two, and three hours after aerosol administration. Results-Before treatment total glutathione concentrations in the epithelial lining fluid were approximately 60% of controls. After three days of twice daily doses each of 600 mg reduced glutathione, total glutathione levels in the epithelial lining fluid increased and remained in the normal range for at least three hours after treatment. Strikingly, even though >95% of the glutathione in the aerosol was in its reduced form, the percentage of oxidised glutathione in epithelial lining fluid increased from 5% before treatment to about 40% three hours after treatment, probably reflecting the use of glutathione as an antioxidant in vivo. No adverse effects were observed. Conclusions-It is feasible and safe to use aerosolised reduced glutathione to augment the deficient glutathione levels of the lower respiratory tract of HIV seropositive individuals. It is rational to evaluate further the efficacy of this tripeptide in improving host defence in HIV seropositive individuals. C1 NHLBI,PULM BRANCH,BETHESDA,MD 20892. NIH,DEPT PHARM,BETHESDA,MD 20892.

To determine if PSA doubling time prior to diagnosis predicted outcome in men with prostate cancer, we evaluated 16 men with prostate cancer who had (1) serial PSA determinations (mean 9.9) on frozen sera from twelve to twenty-six years before diagnosis; (2) at least five years of follow-up in those subjects without metastatic disease (range 5.5-12.3 years); and (3) archival material from diagnosis available for pathologic evaluation. PSA doubling time prior to diagnosis was investigated with relation to patient outcome (regardless of treatment) and the known predictors of tumor behavior, Gleason score and nuclear morphometry. In 5 of 16 men who had evidence of metastatic disease at diagnosis, metastasis developed or they died of prostate cancer during follow-up (group 1). Eleven of 16 had no evidence of metastatic disease during follow-up (group 2). Both Gleason score and variance of nuclear roundness (VNR) were significantly greater for group 1 (p < 0.05). There was no significant difference between the two groups with respect to PSA doubling time, and the PSA level at diagnosis did not correlate with the development of metastatic disease. One of 5 men with no PSA level greater than 4.0 ng/mL prior to diagnosis died within two years of diagnosis. These data suggest that (1) a normal PSA at diagnosis does not exclude an aggressive cancer, and (2) changes in PSA that occur before the diagnosis of prostate cancer may not always predict outcome. Since PSA level is influenced by tumor grade, an inability to correct PSA for tumor grade could have influenced the results.

All 12 protected animals were rechallenged 100 days after the initial inoculation; 8 became infected and yielded virus as expected, but 4 remained uninfected. One of the latter was the SIV-PCR-positive monkey mentioned above, suggesting that cryptic SIV infection may be of significance in immunological protection. The results demonstrate that envelope anti-peptide antibodies have similar protective potential in vivo as antibodies directed to the whole virus. In vitro neutralization competition assays performed with sera from vaccinated macaques in the presence of the free peptides suggest that of the four conserved envelope peptides of the vaccine, the two originating from gp41 rather than the two from gp120 are responsible for inducing the neutralizing anti-syncytial activity.

In this study, we have examined what happens to phospholipids in dying rat platelets. Rat platelets were incubated for up to three days following their activation with thrombin. Platelet death occurred during the first day of incubation. This was indicated by a complete loss of platelet lactate dehydrogenase into the incubation medium. The platelets progressively lost over one-half of their phospholipid content during the three days of incubation. Cholesterol and sphingomyelin (the phospholipid with the highest affinity for cholesterol) were not lost during the same period. Our findings suggest that significant degradation of cellular non-sphingomyelin phospholipid can be triggered by cell death. The preservation of sphingomyelin in dying platelets, may be an adaptive response to maintain cholesterol in a solubilized state within dying cells.

These mutant viruses display the cold-adapted (ca), temperature-sensitive (ts), and attenuation (att) phenotypes. Sequence data indicate that both cp12 and cp45 sustained nucleotide substitutions during cold passage and subsequent cloning. Fifteen nucleotide changes were present in Cp12 and 18 in cp45. Of these changes, some were present in the sequence of the prototype wt strain (Wash/47885/57) or were non-coding changes present in the open reading frames (ORFs). These were considered unlikely to be of significance in contributing to phenotypic differences between the mutants and the JS wt. There were nine remaining changes in cp12 and eight in cp45 that would most likely contribute to their phenotypes. For cp12, two were non-coding changes in regulatory regions, one in the 3' genome leader and one in the NP gene transcription start signal. The remaining seven changes resulted in amino acid substitutions in NP, F, HN, and L. For cp45, two mutations were in a non-coding regulatory region, the 3' genome leader. The remaining six changes resulted in amino acid substitutions in F, HN, and L. Only one amino acid substitution was conserved between cp12 and cp45 (a valine to alanine change at position 384 of the HN gene). These results should prove useful in the future in understanding the genetic basis of attenuation of the cold-passaged PIV3 candidate vaccine viruses. C1 NIAID,INFECT DIS LAB,BETHESDA,MD 20892.

The sequence contains two long open reading frames coding for putative proteins of 559 amino acid residues (p65) and 344 amino acid residues (p39). Amino acid database searches showed that p39 is closely related to vaccinia virus (VV), strain WR, B22R gene product (C12L gene product of strain Copenhagen), which belongs to the family of serine protease inhibitors (serpins). Despite the overall high conservation, differences were observed in the sequences of p39, B22R, and C12L in the site known to interact with proteases in other serpins, suggesting that the serpins of EMV and two strains of VV may all inhibit proteases with different specificities. The gene coding for the ortholog of p65 is lacking in the Copenhagen strain of vaccinia virus; the WR strain contains a truncated variant of this gene (B21R) potentially coding for a small protein (p16) corresponding to the C-terminal region of p65. p65 is a new member of the family of poxvirus proteins including vaccinia virus proteins A55R, C2L and F3L, and a group of related proteins of leporipoxviruses, Shope fibroma and myxoma viruses (T6, T8, T9, M9). These proteins are homologous to the Drosophila protein Kelch involved in egg development. Both Kelch protein and the related poxvirus proteins contain two distinct domains. The N-terminal domain is related to the similarly located domains of transcription factors Ttk, Br-C (Drosophila), and KUP (human), and GCL protein involved in early development in Drosophila. The C-terminal domain consists of an array of four to five imperfect repeats and is related to human placental protein MIPP. Phylogenetic analysis of the family of poxvirus proteins showed that their genes have undergone a complex succession of duplications, and complete or partial deletions.

Scale scores on the Karasek and DOT were linked to information on occupation from die Epidemiologic Catchment Area (ECA) study sample. Scale intercorrelations and factor analysis were performed on those ECA subjects who reported ever having a full-time job (n=11,789). DOTs Substantive Complexity scale was positively correlated with Karasek's Skill Discretion and Decision Authority scales, and DOT's Physical Demands and Hazards scale was positively correlated with Karasek's Physical Demands scale. In addition, the DOT system compared to the Karasek system seems to assess psychosocial work domains less characteristic of traditional industrial jobs (interpersonal stress, expressive work). The content validity of the Karasek scales might be increased with the assessment of these domains. Giving support to Karasek's Demand/Control Model, the factor structure of the psychosocial work environment in the probability sample of five US metropolitan populations yielded two major dimensions: Control, and Physical Demands.

Persons with hFH generally manifest elevations of low density lipoprotein (LDL) cholesterol throughout their lives and have a markedly increased risk of death from coronary artery disease. The hypercholesterolemia of hFH is responsive to medication and diet, and, if detected early, aggressive LDL cholesterol control may prevent or substantially delay cardiovascular disease. However, evidence suggests that many persons with hFH are undetected and inadequately treated. On July 20-21, 1992, the National Heart, Lung, and Blood Institute sponsored a workshop to assess the current understanding of the diagnosis and management of hFH, to emphasize recommendations for identification and management that are known to be effective, and to identify opportunities and needs for intervention and research.

The term ''penetrance'' has been used to describe the degree to which a given genotype expresses itself in the phenotype of the individual. Although many explanations for this phenomenon have been put forward, the molecular bases for this have been difficult to define. The investigation of the disease familial hypercholesterolemia (FH) has been used as a paradigm at many different levels. This condition, in which a wide variety of mutations in the low density lipoprotein (LDL) receptor gene leads to elevated concentrations of LDL particles has a wide array of clinical manifestations that are variably expressed in both patients who are heterozygous and homozygous for mutations at the LDL receptor allele. Progress in understanding lipoprotein metabolism, atherogenesis, and the development of molecular biology and transgenic expression techniques coverage to utilize homozygous FH as a paradigm for understanding the molecular basis of penetrance. Elucidation of the key factor in altering the clinical features expressed by patients with FH have theoretical implications in understanding the polygenic nature of atherosclerosis as well as practical ramifications in the treatment of patients with FH.

In the current study we investigated the ability of hepatic microsomes from cynomolgus monkeys, Fischer-344 rats and humans to metabolically activate these compounds. Monkeys had almost no capacity to activate the quinoxaline-type compounds to mutagens in the Ames test relative to rats and humans but were able to activate the quinoline, pyridoindole and pyridoimidazole compounds. Differences in the mutagenicity of the quinoline and quinoxaline compounds by monkeys and rats was related to differences in cytochrome P-450-mediated N-oxidation between the species. This suggests that monkeys and rats may have different hepatic cytochrome P-450 isozymes, which are important for the metabolic activation of quinolines and quinoxalines, or that the orthologous monkey cytochromes show a select substrate specificity for the quinolines over the quinoxalines.

An 18-kDa histone homologue, Hcl, is conserved among C. trachomatis serovars and C. psittaci. The other histone homologue, Hc2 (encoded by hctB), varies in size between C. trachomatis serovars but is present in reduced amounts or absent from C. psittaci. The variation in Hc2 size among C. trachomatis serovars was found to be due to internal deletions from a region of the hctB gene encoding lysine- and alanine-rich pentameric repeats.

Both GluR5-1d and GluR6-2 appear to be generated by alternative splicing at analogous sites 14 codons following the fourth putative transmembrane segment. The principal transcripts of GluR5 and GluR6 were detected by Northern analyses of several regions of mammalian brains as 4 and 6 kb bands, respectively. Potential roles for these receptors in development are indicated by detection of their mRNAs in mouse embryos of 11 days gestation. These findings add to the description of the remarkable diversity of glutamate receptor gene expression. C1 STANFORD UNIV,DEPT BIOL SCI,SLEEP RES CTR,STANFORD,CA 94305.

INTENSIVE TREATMENT OF DIABETES ON THE DEVELOPMENT AND PROGRESSION OF LONG-TERM COMPLICATIONS IN INSULIN-DEPENDENT DIABETES-MELLITUS SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID GLUCOSE CONTROL; METABOLIC CONTROL; GLYCEMIC CONTROL; RETINOPATHY; AGE; PREVALENCE; DIAGNOSIS; INFUSION; RISK AB Background. Long-term microvascular and neurologic complications cause major morbidity and mortality in patients with insulin-dependent diabetes mellitus (IDDM). We examined whether intensive treatment with the goal of maintaining blood glucose concentrations close to the normal range could decrease the frequency and severity of these complications. Methods. A total of 1441 patients with IDDM - 726 with no retinopathy at base line (the primary-prevention cohort) and 715 with mild retinopathy (the secondary-intervention cohort) were randomly assigned to intensive therapy administered either with an external insulin pump or by three or more daily insulin injections and guided by frequent blood glucose monitoring or to conventional therapy with one or two daily insulin injections. The patients were followed for a mean of 6.5 years, and the appearance and progression of retinopathy and other complications were assessed regularly. Results. In the primary-prevention cohort, intensive therapy reduced the adjusted mean risk for the development of retinopathy by 76 percent (95 percent confidence interval, 62 to 85 percent), as compared with conventional therapy. In the secondary-intervention cohort, intensive therapy slowed the progression of retinopathy by 54 percent (95 percent confidence interval, 39 to 66 percent) and reduced the development of proliferative or severe nonproliferative retinopathy by 47 percent (95 percent confidence interval, 14 to 67 percent). In the two cohorts combined, intensive therapy reduced the occurrence of microalbuminuria (urinary albumin excretion of greater-than-or-equal-to 40 mg per 24 hours) by 39 percent (95 percent confidence interval, 21 to 52 percent), that of albuminuria (urinary albumin excretion of greater-than-or-equal-to 300 mg per 24 hours) by 54 percent (95 percent confidence interval, 19 to 74 percent), and that of clinical neuropathy by 60 percent (95 percent confidence interval, 38 to 74 percent). The chief adverse event associated with intensive therapy was a two-to-threefold increase in severe hypoglycemia. Conclusions. Intensive therapy effectively delays the onset and slows the progression of diabetic retinopathy, nephropathy, and neuropathy in patients with IDDM.

In patients with the acquired immunodeficiency syndrome (AIDS), toxoplasmic encephalitis is usually a presumptive diagnosis based on the clinical manifestations, a positive antitoxoplasma-antibody titer, and characteristic neuroradiologic abnormalities. A response to specific therapy helps to confirm the diagnosis, but it is unclear how rapid the response should be. We studied the course of patients treated for acute toxoplasmic encephalitis and evaluated objective clinical criteria for this empirical diagnosis. Methods. A quantifiable neurologic assessment was used prospectively to evaluate the clinical outcome of patients with AIDS and toxoplasmic encephalitis who were treated with oral clindamycin (600 mg four times a day) and pyrimethamine (75 mg every day) for six weeks. Results. Thirty-five of 49 patients (71 percent) responded to therapy, and 30 of these (86 percent) had improvement by day 7. Thirty-two of those with a response (91 percent) improved with respect to at least half of their base-line abnormalities by day 14. Improvement in neurologic abnormalities within 7 to 14 days after the start of therapy was strongly associated with the neurologic response at 6 weeks. The four patients in whom treatment failed and the two patients with lymphoma had progressing neurologic abnormalities or new abnormalities during the first 12 days of therapy. Nonlocalizing abnormalities (headache and seizure) improved regardless of the clinical outcome. Conclusions. Oral clindamycin and pyrimethamine are an effective treatment for toxoplasmic encephalitis. Patients who have early neurologic deterioration despite treatment or who do not improve neurologically after 10 to 14 days of appropriate antitoxoplasma therapy should be considered candidates for brain biopsy.

One major example is the replacement of keratin 5/keratin 14 (K5/K14) keratin intermediate filaments (KIFs) by K1/K10 KIFs during terminal differentiation in the epidermis. The present work was undertaken to explore how this may occur. We have induced lysine-lysine cross-links with disulfosuccinimidyl tartrate in K5/K14 KIFs in order to determine the axial dimensions and relative axial alignments of the K5/K14 molecules. Many of the cross-links induced in subfilamentous oligomers containing one, two, or three molecules were also found in the intact KIF, indicating that the body of data thus generated provides physiologically relevant information on the structural organization in the KIF. A least-squares analysis using as data the positions of lysine residues involved in 23 induced cross-links has allowed the axial alignments of the various coiled-coil segments in the rod domain to be determined. Three modes of antiparallel alignment of two neighboring molecules were found: A11 (staggered by -16.7 nm), A22 (staggered by 28.8 nm), and A12 (almost in register; staggered by only 0.3 nm). Since the axial repeat length is about 1 nm less than the molecular length, the data require a fourth mode of molecule alignment, termed A(CN), in which similarly directed molecules are overlapped by the equivalent of about 5-10 residues. Interestingly, these axial alignments and dimensions are essentially identical to those adduced previously for K1/K10 KIF [Steinert, P. M., Marekov, L. N., Fraser, R. D. B., & Parry, D. A. D. (1993) J. Mol. Biol. 230, 436-452], thus indicating that the two types of KIF have conserved structures. Accordingly, our new data suggest that exchange of the K5/K14 molecules by K1/K10 molecules can occur simply because both have the same linear dimensions and axial configurations. Further work will be necessary to determine whether the lack of assembly compatibility of molecules in other IF systems is due to variations in their axial dimensions and alignments.

In this study, characteristics of several screening tests for NIDDM were compared. Methods: Among Pima Indians participating in an epidemiologic study, the sensitivity and specificity for detecting NIDDM of fasting plasma glucose (FPG) levels and two measures of glycated hemoglobin (HbA1 or HbA1c) were compared in 2092 fasting subjects. Glycated hemoglobin, quantitative glycosuria, and dipstick glycosuria were compared in 237 nonfasting subjects. Diabetes was diagnosed using an oral glucose tolerance test if the 2-hour postload venous plasma glucose concentration was 11.1 mmol/L (200 mg/dL) or greater- The area under the relative operating characteristic curve was used to compare tests. Results: In fasting subjects, the sensitivity for detecting diabetes with 98% specificity was 78.8% for HbA, level of 7.5% or greater, 80.3% for HbA1c level of 6.3% or greater, and 88.0% for FPG level of 6.83 mmol/L (123 mg/dL) or greater. By relative operating characteristic analysis, there were no significant differences between FPG and HbA1c, but FPG was significantly more sensitive than HbA1. In nonfasting subjects the sensitivity at 98% specificity was 92.9% for HbA, level of 7.3% or greater, 80.6% for quantitative urine glucose level of 1.94 mmol/L (35 mg/dL) or greater, and 64.3% for trace or greater of dipstick glycosuria. The area under the relative operating characteristic curve was significantly greater for glycated hemoglobin than for either measure of glycosuria. Conclusions: Although FPG has the best screening properties, HbA1c, HbA1, and quantitative urine glucose also provide high specificity, and approximately 80% sensitivity in detecting NIDDM. The choice of a particular method could depend on cost, convenience, and availability. RP HANSON, RL (reprint author), NIDDKD,DIABET & ARTHRITIS EPIDEMIOL SECT,PHOENIX,AZ, USA.

Cellular levels of the aberrant transcript can exceed that of productive light chain RNA, so a large proportion of the V(L) gene-derived products obtained on PCR amplification of hybridoma cDNA may not encode a functional protein. We have developed a method in which antibody variable region genes are recovered from hybridoma cDNA using a unique set of V gene family-specific primers; the V region genes are then spliced by PCR, in the form 5'-V(L)-LINKER-V(H)-3' (where the linker encodes [GlyGlyGlyGlySer]3), and cloned into an expression vector under control of T7 RNA polymerase. Plasmid DNA is isolated from colonies, and the insert is expressed in an in vitro rabbit reticulocyte lysate-based coupled transcription/translation system, in a microtiter plate format. Since aberrantly rearranged V(L) kappa genes contain a translation termination codon at amino acid position 105, only constructs containing the correctly rearranged gene produce a protein of the predicted size. We demonstrate the method by producing the single-chain form of OKT9, a murine IgG1 which binds to the human transferrin receptor, and extend the results to show thal the protein generated by the in vitro expression system retains the antigen binding properties of the parent antibody. Our method will be generally useful for screening single-chain antibodies for function prior to large scale production in vivo. C1 NINCDS, SURG NEUROL BRANCH, BIOCHEM SECT, BETHESDA, MD 20892 USA.

To test whether specific PKC isozymes are involved in myeloid differentiation, we have studied the effect of overexpression of PKC-alpha, -betaII, -delta, -epsilon, -zeta and -eta in 32D, a mouse myeloid progenitor cell line that does not differentiate in response to 12-O-tetradecanoylphorbol-13-acetate (TPA). No significant morphological or phenotypic changes could be observed in unstimulated cells that overexpress any of these isozymes. However, the cell lines that overexpressed PKC-alpha or -delta had acquired the ability to become mature macrophages 2-6 h after TPA stimulation. The overexpression of PKC-betaII, -epsilon, -zeta, or -eta, in contrast, did not permit TPA-induced differentiation. These results indicate that only these two members of the PKC gene family can participate in TPA-induced myeloid differentiation. C1 NCI,GENET LAB,BLDG 37,RM 2B26,BETHESDA,MD 20892.

PrP(Sc) and the carboxyl-terminal proteinase K resistant core, PrP27-30, have the potential to form amyloid as a result of a post-translational event or conformational abnormality. We have studied the conformational transitions of both proteins reconstituted into liposomes, associated in solid state in thin films, and dissociated by guanidine HCl. The secondary structure of PrP(sc) in liposomes deduced from analysis of circular dichroism spectra contained approximately 34% beta-sheets, approximately 20% alpha-helix, and approximately 46% beta-turns and random coil. Cleavage of the amino-terminal region of PrP(Sc) resulted in all-beta PrP27-30, with an estimated approximately 43% beta-sheet, no alpha-helix, and approximately 57% beta-turns and random coil. The PrP(Sc) associated in thin films with a tertiary structure perturbation corresponding to unfolding, while the secondary structure was preserved. The PrP27-30 assembled into the solid state with a similar perturbation of tertiary structure but with a large increase in the beta-sheet content, probably due to an intermolecular alignment of the external beta-sheets, or to a secondary structure transition, or both. The various conformational states had little or no impact on infectivity. Equilibrium dissociation and unfolding demonstrated a greater resistance of PrP27-30 to denaturation. The dissociated monomers unfolded through intermediate(s), suggesting the presence of protein domains with distinct secondary structure stabilities. The results provide experimental evidence for the beta-sheet type assembly of scrapie amyloid PrP27-30 in the solid state and demonstrate the importance of amino-terminal cleavage in the stability and alignment of the amyloid-forming monomers.

In this study, components of the gastrin-releasing peptide receptor (GRP-R) regulating internalization were identified. Four GRP-R mutants with stop codons placed at variable distances distal to the putative palmitoylation sites Cys340-341 were transiently expressed in CHOP fibroblasts. A construct with a minimal carboxyl tail deletion, T375, bound and internalized agonist similarly to wild type receptor. Progressively larger truncations of the carboxyl terminus, however, increasingly impaired GRP-R-mediated internalization without altering receptor-agonist affinity. Three additional constructs were created: one with the putative palmitoylation sites replaced with Ala (CC340-341 AA), one with the carboxyl-terminal protein kinase C-consensus sequence converted to Ala (TS360-361AA), and one with all Ser and Thr distal to Cys341 converted to Ala, Asn, or Gly (JF1). All constructs bound agonist similarly to wild type receptor. CC340-341AA internalized similarly to native receptor (93 +/- 3% of wild type by 60 min), whereas internalization of TS360-361AA was partially attenuated (64 +/- 2% of wild type by 60 min). JF1, however, internalized as poorly as T346, with only 16 +/- 2% of the wild type receptors internalized by 60 min. To assess G-protein coupling, selected receptor constructs were stably transfected into Balb fibroblasts, and phosphoinositol hydrolysis was determined. The largest GRP-R truncation, T346, increased total inositol phosphates (EC50 = 2.9 +/- 0.9 nm) similarly to wild type receptor (EC50 = 5.1 +/- 2.2 nm), as did CC340-341AA (EC50 = 5.4 +/- 1.5 nm) and TS360-361AA (EC50 = 3.1 +/- 1.2 nM). These data demonstrate that the multiple Ser and Thr located within the GRP-R carboxyl terminus distal to Cys341, including but not limited to those within the protein kinase C-concensus sequence, specifically regulate GRP-R internalization rates independent of receptor-G-protein coupling.

An exhaustive search for down-regulated genes identified a single gene. Thirty-two different cDNA fragments derived from the up-regulated mRNA of tadpole intestine 18 h after addition of TH were cloned. They map to no more than 22 distinct genes. The isolation of multiple cDNA fragments derived from a single mRNA indicates that the complexity of up-regulated genes is limited. Both ubiquitous and intestine-specific up-regulated genes were found in this screen. The majority of these genes respond directly to TH induction as judged by the resistance of up-regulation to inhibitors of protein synthesis. The biological significance of these genes is supported by their dramatic regulation in the GI tract during spontaneous metamorphosis. C1 CARNEGIE INST WASHINGTON,DEPT EMBRYOL,BALTIMORE,MD 21210.

Since this human protein is not readily available in substantial quantity for detailed characterization of its biochemical, biological, and pharmacological properties, we sought to express it in Escherichia coli in order to study its structure-function relationship. However, bacterial overproduction of homodimeric proteins with interchain disulfide bonds, such as Clara cell 10-kDa protein, was thought to be impossible until we achieved expression of native uteroglobin (Miele, L., Cordella-Miele, E., and Mukherjee, A. B. (1990) J. Biol. Chem. 265, 6427-6435). Here, we report high level production of recombinant native dimeric human Clara cell 10-kDa protein in E. coli and its characterization. Recombinant human Clara cell 10-kDa protein forms its disulfide bonds within the bacterial cytoplasm. The purified protein possesses two of the most important activities characteristic of uteroglobin: (i) it is an excellent substrate of transglutaminase, and (ii) it is a potent inhibitor of porcine pancreatic and, more importantly, human synovial phospholipase A2. These results demonstrate that human Clara cell 10-kDa protein and rabbit uteroglobin have very similar biochemical properties. Our data suggest that this protein may possess immunomodulatory and antiinflammatory activities of potential physiological and pharmacological importance.

Its recognition sequence, TTTCGCGC, is present in two of the human adenovirus early promoters and in several promoters of cellular genes whose products are implicated in the control of cell proliferation. These observations suggest that E2F may play an important role in cell-cycle regulation and prompted us to ask whether E2F-like activities are present in yeast. We found that the E2F motif can function as an activating sequence in Schizosaccharomyces pombe when cloned upstream of a reporter gene. Consistent with this, the expression of adenovirus E2 promoter in S. pombe was dependent on both E2F motifs of this promoter. A protein, spE2F, that binds to the E2F site was partially purified from S. pombe using DNA-affinity chromatography. The binding specificity of this protein was compared to that of human E2F using a number of mutant E2F sites as competitors. These studies showed that spE2F recognizes a sequence closely related to the E2F site. Ultraviolet cross-linking and Southwestern blot studies indicated that the molecular size of spE2F is 30 kDa. Previous studies have shown that a cis-acting element, ACGCGTNA, also called MluI cell cycle box, or MCB, is critical for the regulated expression of cell cycle related genes both in fission and budding yeast. In S. pombe, the cdc10 gene product binds to this element and controls the cell cycle related genes. Electrophoretic mobility shift assays and molecular size determination studies indicated that spE2F is different from that encoded by cdc10. Thus, our studies suggest that spE2F is a novel transcription factor. We discuss these results in light of recent observations about the periodically expressed genes involved in the cell cycle progression in yeast.

We studied the effects of fetal bovine serum (FBS) and of exogenous HA and HA-oligomers on the expansion process. Maximum retention of HA in the COC matrix, and hence complete COC expansion, occurs when 1% FBS is continuously present during the first 18 h of culture. Irrespective of the culture time, HA synthesized when serum is absent is primarily in the medium, whereas HA synthesized when serum is present is primarily in the cell matrix. These findings support the hypothesis that the serum factor, identified as an inter-alpha-trypsin inhibitor by Chen et al. (Chen, L., Mao, S. J., and Larsen, W. J. (1992) J. Biol. Chem. 267, 12380-12386), is a structural component of the matrix. Addition of exogenous HA or of HA oligomers of decasaccharide size (GlcUA-GlcNAc)5 or larger effectively displaces endogenously synthesized HA from the matrix into the medium, thereby preventing COC expansion. Addition of exogenous chondroitin sulfate affects neither matrix organization nor COC expansion, thus indicating specificity of the binding of some structural component(s) to HA. Fully expanded, COCs disassemble when cultured longer than 18 h, a process which occurs also in vivo and which correlates with loss of oocyte fertilizability both in vivo and in vitro. This process involves release of macromolecular HA from the matrix into the medium, with loss of 50% of the HA in the first 8 h of incubation after full expansion. The release is not facilitated when HA oligomers, long enough to prevent matrix formation, are added to the culture medium after the COCs are fully expanded. This suggests that cooperative binding to HA of either the serum factor, an endogenously synthesized factor(s), or both is required to stabilize the fully expanded COC matrix.

By strategic labeling of single-stranded probe sequences, DHDA allows the identification of specific heteroduplex structures that contribute to the differentiation of DQA1 and DQB1 alleles. Because of the high degree of polymorphism among major histocompatibility complex class II second exon sequences, this analysis of 50 different heteroduplex molecules provides evidence of the importance of unpaired bases and mismatched base pairs and their effect on heteroduplex electrophoretic-mobility differences. This strategy is further used to genotype accurately a family for DQA1 which was previously analyzed by sequence specific oligonucleotide (SSO) probe hybridization. To differentiate by SSO-typing among the DQA1 and DQB1 alleles analyzed in this study requires the use of 23 different probes. Equivalent results are obtained by DHDA using only three probes. Therefore, this study suggests that accurate HLA-typing can be simplified by DHDA. Additionally, DHDA may be useful for differentiation of DNA sequence polymorphisms in other genetic systems.

All changes in the loop of the predicted IRE hairpin and in the unpaired cytosine residue characteristically found in IRE stems significantly decreased the apparent affinity of the RNA for the IRE-BP. Similarly, alteration in the spacing and/or orientation of the loop and the unpaired cytosine of the stem by either increasing or decreasing the number of base pairs separating them significantly reduced efficacy as a competitor. It is inferred that the IRE-BP forms multiple contacts with its cognate RNA, and that these contacts, acting in concert, provide the basis for the high affinity of this interaction.

Work in the present authors' laboratory has shown that the formation of 9- and 13-hydroxyoctadecadienoic acid (HODEs), 15-lipoxygenase-derived metabolites of linoleic acid, are involved in the mitogenic response to EGF in these cells (Glasgow et al. (1992) J. Biol. Chem. 267, 10771-10779). SHE cells also produce prostaglandin E2 (PGE2) and prostaglandin F2alpha (PGF2alpha). We now report the effects of HODEs and prostaglandins on EGF-dependent expression of the growth-related proto-oncogene c-myc in SHE cells. Treatment of cells with eicosatetraynoic acid (ETYA), which blocks EGF-dependent HODE formation, inhibited the mitogenic response to EGF, while exogenous 13-HODE potentiated EGF-dependent DNA synthesis. However, neither ETYA or 13-HODE altered the accumulation of c-myc mRNA in response to EGF. In contrast, PGE2 inhibited EGF-induced DNA synthesis and down-regulated EGF-stimulated c-myc mRNA accumulation in a dose-dependent manner, whereas PGF2alpha had no effect on these responses. PGE2, but not PGF2alpha, induced a rapid increase in cAMP formation, and both forskolin and 8-(4-chlorophenylthio)-cAMP mimicked the inhibitory effects of PGE2 on EGF-dependent DNA synthesis and c-myc mRNA accumulation, suggesting that the involvement of cAMP. The results indicate that the modulation of EGF-dependent DNA synthesis by PGE2, but not by HODEs, is associated with altered expression of the proto-oncogene c-myc in SHE cells.

Two recent studies have found that infants who received intramuscular vitamin K were at twice the expected risk tor cancer during childhood. Since nearly all newborns in the United States receive this drug, the public health implications ot this association, it confirmed, would be substantial. Methods. We examined the relation between vitamin K and cancer in a nested case-control study that used data from the Collaborative Perinatal Project, a multicenter, prospective study of pregnancy, delivery, and childhood. Among 54,795 children born from 1959 through 1966, 48 cases ot cancer were diagnosed after the first day ot lite and before the eighth birthday. Each case child was matched with five randomly selected controls whose last study visit occurred at or after the age when the case child's cancer was diagnosed. Exposure to vitamin K was determined from study forms and medical records. Results. Vitamin K had been administered to 68 percent of the 44 case children and 71 percent of the 226 controls for whom data were available (matched odds ratio, 0.84; 95 percent confidence interval, 0.41 to 1.71). The odds ratio was 0.47 (95 percent confidence interval, 0.14 to 1.55) for leukemia and 1.08 (95 percent confidence interval, 0.45 to 2.61) for other cancers. Sequential adjustment for potential confounding factors did not change the results substantially. Conclusions. We found no association between exposure to vitamin K and an increased risk of any childhood cancer or of all childhood cancers combined, although a slightly increased risk could not be ruled out. The benefits of neonatal vitamin K prophylaxis against hemorrhagic disease have been well described. Unless other evidence supporting an association between vitamin K and cancer appears, there is no reason to abandon the routine administration of vitamin K to newborns.

Mn2+ entry (fura2 quenching) was about 1.6 fold higher in internal Ca2+ pool-depleted acini (Ca2+-depl acini) than in unstimulated cells. Mn2+ entry into Ca2+-depl acini was increased at external pH > 7.4 and decreased at pH < 7.4. Pretreatment of Ca2+-depl acini with the relatively hydrophobic carboxylic group reagent, N,N'-dicyclohexylcarbodiimide de (DCCD, 50 mu M for 30 min) resulted in the inhibition of Mn2+ entry into Ca2+-depl acini to unstimulated levers. Another hydrophobic carboxyl group reagent, N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline (EEDQ) and the relatively hydrophilic carboxyl group reagents, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) and 1-cyclohexyl-3-(2-morpholinoethyl)carbodiimide (CMCD) did not affect Mn2+ entry. Similar to the effects in intact acini, Ca2+ influx into BLMV was decreased when the external pH was lowered below 7.4. Also DCCD (5 mM, 30 min), but not EEDQ, decreased (40%) Ca2+ influx in BLMV. However, unlike in acini, the hydrophilic reagents, EDC, EAC, and CMCD decreased Ca2+ permeability in BLMV and the effects were nonadditive with the decrease induced by DCCD. The aggregate effects of carboxyl group reagents on the Ca2+ and Mn2+ permeability in BLMV and intact acini, respectively, suggest that a critical carboxyl group (most likely accessible from the cytoplasmic side of the plasma membrane) is involved in divalent cation flux in rat parotid acinar cells.

RT binds to template-primer (T/P) tightly to form the first complex in the reaction sequence poised to conduct DNA synthesis upon the addition of dNTP and Mg2+. We have made use of this property to kinetically analyze poly(rA)-(dT)n interactions with recombinant homo- and heterodimeric HIV-1 RT derived from HXB2R proviral DNA. A T/P challenge assay was used to quantitatively follow RT-T/P complex formation. The homo- and heterodimeric forms of RT bound to poly(rA)-(dT)16 in a kinetically similar fashion. There was no more than a 2-fold difference in k(cat) or for any T/P parameter examined: K(m), K(d), k(on), k(off) determined from a binary complex or from a complex incorporating fTMP, processivity, and stoichiometry of binding. In contrast, it was found that the T/P K(m) with heterodimeric RT derived from the NY5 strain was significantly greater than that determined for HXB2R enzyme, indicating that a kinetic diversity exists between RT derived from different viral strains. Since HXB2R RT binds to poly(rA)-(dT)16 tightly, K(d) < 1 nM, active-site titrations are facilitated. At saturation, one T/P binds per two polypeptides, suggesting that RT binds substrate productively as a dimer and that if monomers are present they must rapidly form dimers in the presence of T/P. In contrast, when the template to primer nucleotide ratio was diminished, the apparent number of T/P binding sites increased to 2 per dimer. The K(d) for poly(rA)-(dT)n was dependent on the length of the primer, with short primers binding with a lower affinity primarily due to a more rapid dissociation rate constant. The dissociation reaction could often be better fitted to a double-exponential decay, suggesting that multiple conformations of the RT-T/P complex exist.

We have examined epsilon4 frequencies in. four distinct, normal, elderly control groups and, most importantly, in patients with amyloid-forming diseases whose epsilon4 distributions were not previously known (Creutzfeldt-Jakob disease, familial amyloidotic polyneuropathy, Down's syndrome). There were no differences between any of these controls and published control series, cementing the relevance of epsilon4 for late-onset AD. The increase in late-onset AD was confirmed in two new series. C1 DUKE UNIV,MED CTR,BRYAN ALZHEIMERS DIS RES CTR,DIV NEUROL,DURHAM,NC 27710. SUNY,DEPT PSYCHIAT,STONY BROOK,NY 11794.

In order to know whether this different localization was associated with a different pharmacological selectivity, we tested the effect of new cocaine analogs on tritiated dopamine ([H-3]DA) uptake in primary cultures of rat embryonic mesencephalic cells. In these cultures, [H-3]DA was taken up by a nomifensine-sensitive, but desipramine and fluoxetine-insensitive process, reflecting selective uptake by the dopaminergic transporter. 3beta-(4-Chlorophenyl)tropan-2beta-carboxylic acid methyl ester (RTI-COC-31) was by far the most potent inhibitor of the [H-3]DA uptake, presenting an IC50 of 3.8 nM, while the corresponding analog with an unsubstituted phenyl ring (WIN 35,065-2) was 38 times less potent. The enantiomer of WIN 35,065-2, namely WIN 35,065-3, was 30 times less potent than the former. A similar pattern was found for the relative ability of these compounds to inhibit binding of the radiolabeled cocaine derivative [I-125]RTI-55 to membranes prepared from mesencephalic cultures. The order of potencies found for the three cocaine analogs on mesencephalic cultures was similar to that previously obtained in [H-3] WIN 35,428 binding experiments and [H-3]DA uptake inhibition in adult rat striatum, suggesting that the pharmacological selectivity of cocaine sites functionally related to the DA transporter in cultured embryonic neurons does not differ from that obtained in adult rat brain.

A series of water-soluble N-(3,4,5-trimethoxybenzyl)aniline salts has therefore been synthesized in which the olefinic bridge of the stilbenes is replaced by an aminomethylene hydrochloride moiety. A relationship was found between the size of the substituent in the 4-position of the aniline ring and both antitubulin activity and cytotoxicity, such that the smaller the substituent, the greater the potency. The most promising of the newly synthesized compounds was 4-methyl-N-(3,4,5-trimethoxybenzyl)aniline hydrochloride, with an IC50 value of 3.5 muM for inhibition of tubulin polymerization and cytotoxicity for a wide variety of cancer cell lines. The cytotoxicities of the benzylaniline hydrochlorides correlated remarkably well with their antitubulin activities.

In this study, the free glutamine content of mouse cerebral astrocytes incubated with 0.1 mM glutamate and 0.1 mM ammonium increased by 80-90% when the extracellular K+ concentration was raised from 3 to 12 mM. The corresponding K+-induced intracellular alkalinization of +0.13 pH units only partially reversed a glutamate-induced intracellular acidification of -0.24 pH units. By comparison, adjustment of extracellular pH from 7.4 to 7.8 shifted intracellular pH by + 0.25 pH units, fully reversing the glutamate-induced acidification and increasing glutamine content by 120-180%. The effect of K+ on intracellular pH increased to + 0.25 pH units in bicarbonate-buffered solution, suggesting that the regulation of glutamine formation by extracellular K+ is enhanced in the presence of bicarbonate.

Insulin and IL-4 sensitivity was restored to 32D cells by expression of IRS-1, the principal substrate of the insulin receptor. Although 32D cells possessed receptors for both factors, they lacked the IRS-1-related protein, 4PS, which becomes phosphorylated by tyrosine in insulin- or IL-4-responsive lines after stimulation. These results indicate that factors that bind unrelated receptors can use similar mitogenic signaling pathways in hematopoietic cells and that 4PS and IRS-1 are functionally similar proteins that are essential for insulin- and IL-4-induced proliferation.

Many clinicians advocate routine ultrasound screening during pregnancy to detect congenital anomalies, multiple-gestation pregnancies, fetal growth disorders, placental abnormalities, and errors in the estimation of gestational age. However, it is not known whether the detection of these conditions through screening leads to interventions that improve perinatal outcome. Methods. We conducted a randomized trial involving 15,151 pregnant women at low risk for perinatal problems to determine whether ultrasound screening decreased the frequency of adverse perinatal outcomes. The women randomly assigned to the ultrasound-screening group underwent one sonographic examination at 15 to 22 weeks of gestation and another at 31 to 35 weeks. The women in the control group underwent ultrasonography only for medical indications, as identified by their physicians. Adverse perinatal outcome was defined as fetal death, neonatal death, or neonatal morbidity such as intraventricular hemorrhage. Results. The mean numbers of sonograms obtained per woman in the ultrasound-screening and control groups were 2.2 and 0.6, respectively. The rate of adverse perinatal outcome was 5.0 percent among the infants of the women in the ultrasound-screening group and 4.9 percent among the infants of the women in the control group (relative risk, 1.0; 95 percent confidence interval, 0.9 to 1.2; P = 0.85). The rates of preterm delivery and the distribution of birth weights were nearly identical in the two groups. The ultrasonographic detection of congenital anomalies had no effect on perinatal outcome. There were no significant differences between the groups in perinatal outcome in the subgroups of women with post-date pregnancies, multiple-gestation pregnancies, or infants who were small for gestational age. Conclusions. Screening ultrasonography did not improve perinatal outcome as compared with the selective use of ultrasonography on the basis of clinician judgment.

For stroke-free Framingham Study participants aged 55-88 years (n = 1,702), blood pressure levels were averaged over five biennial examinations (1956-1964) when few hypertensives were being treated, and examined in relation to neuropsychological tests administered between 1976 and 1978. With age, education, occupation, cigarette smoking, alcohol consumption, and gender controlled, blood pressure levels and chronicity of hypertension were inversely related to the composite score and measures of attention and memory. This was true for the full sample, for a subsample untreated during blood pressure measurement (n = 1,485), and for a subsample untreated throughout the entire study period (n = 1,038). For example, decline per 10 mmHg increment in blood pressure ranged from -0.04 to -0.07 standard score units (z) for the composite score. A negative finding previously was most likely due to blood pressure measurement concurrently with neuropsychological testing, or too few measurements. Hypertension-associated pathogenic processes may cause mild cognitive impairment, but other mechanisms need to be considered.

HIV-1 seroprevalence was significantly higher in Hispanic men (50%; odds ratio (OR) = 1.83,95% confidence interval (CI) 1.41-2.39) and black men (47%; OR = 1.62,95% CI 1.21-2.16) compared with white men (35%). Both Hispanic and black men more frequently reported a history of sexually transmitted diseases. Overall, Hispanics had the highest risk profile and blacks the lowest risk profile with respect to certain high-risk sexual behaviors (e.g., receptive anal intercourse and use of anonymous sexual partners) and recreational drug. use. After multivariate adjustment, black race remained a significant independent risk factor for HIV-1 seropositivity (OR = 1.60, 95% CI 1.132. 26), but Hispanic ethnicity was no longer statistically significant (OR = 1.17, 95% CI 0.82-1.69). Most of the excess HIV-1 prevalent infection among Hispanics was explained by their predominant recruitment from Los Angeles-the study center with the highest HIV-1 seroprevalence-and their greater prevalence of a history of sexually transmitted diseases and certain high-risk sexual practices. By contrast, adjustment for these same risk behaviors failed to explain the observed black-white differences in HIV-1 seroprevalence, and further studies are needed to elucidate the reasons for these unexplained racial differences. HIV-1 educational programs for homosexual men should take into account the behavioral differences that exist between white and minority racial/ethnic groups.

Between 1986 and 1990 data were obtained at five clinical centers from 270 patients with branch retinal vein occlusion and 1,142 controls. Data were collected from interviews, clinical examinations, and laboratory analyses of blood specimens. An increased risk of branch retinal vein occlusion was found in persons with a history of systemic hypertension, a history of cardiovascular disease, an increased body mass index at 20 years of age, a history of glaucoma, and higher serum levels of alpha2-globulin. Risk of branch retinal vein occlusion decreased with higher levels of alcohol consumption and high-density lipoprotein cholesterol. The data suggest a cardiovascular risk profile for patients with branch retinal vein occlusion and indicate that 50% of patients with branch retinal vein occlusion may be attributable to hypertension. Our findings support current public health recommendations to diagnose and treat hypertension, reduce weight, increase physical activity, and maximize serum high-density lipoprotein levels.

Biol. Chem. 266, 16911-16916]. In the present work the 130 kDa protein was identified as vinculin by the following criteria. (1) It is detected on protein immunoblots of thrombin-activated platelets by both monoclonal anti-phosphotyrosine and anti-vinculin antibodies. (2) Removal of N-linked sugars with peptide-N-glycosidase or reduction did not change the molecular mass of vinculin or of the 130 kDa protein on SDS/PAGE. (3) The 130 kDa tyrosine-phosphorylated protein associates with Triton-soluble fraction of platelets as does vinculin. (4) The 130 kDa protein immunoprecipitated by anti-vinculin monoclonal antibody reacts with anti-phosphotyrosine antibody; when immunoprecipitated by anti-phosphotyrosine antibody it reacts with anti-vinculin antibody. (5) The 130 kDa tyrosine-phosphorylated protein and vinculin focus isoelectrically at pI 5.4-5.8. Our finding that vinculin is a major platelet protein that undergoes Ca2+-dependent tyrosine phosphorylation during platelet activation may provide clues to the function of this protein.

Groups of male F344 rats at 9 weeks of age were exposed to cumulative doses of 0.5 or 2.0 mmol AAF per kg body weight given by gavage daily 5 days per week over an 8-week period and maintained with no further exposure for up to 8 weeks. Administration of AAF resulted in the formation of N-deoxyguanosin-(8-yl)-2-aminofluorene in liver DNA in relationship to dose. In centrilobular hepatocytes the zone of glutamine synthetase-expressing cells was reduced by exposure. By 8 weeks, but not at 4 weeks, the higher of the two doses of AAF provoked an increase in cell proliferation measured by immunohistochemical incorporation of bromode-oxyuridine. Altered hepatocellular foci expressing the placental form of glutathione transferase were induced by the high dose of AAF at 4 weeks, but not at the low dose. At 8 weeks the incidence of foci at the high dose was 79 times that induced by the low dose. These foci were highly proliferative. In animals exposed to AAF for 8 weeks and maintained for 4 weeks with no exposure, DNA adducts decreased by 80% and cell proliferation subsided by 80%, although the glutamine synthetase zone remained diminished. After discontinuation of AAF, the number of foci diminished by 50% and their proliferation subsided by 80% at 4 weeks, indicating a phenotypic reversion of many foci. With this protocol of administration of precise doses of AAF, we have established non-linearity of effects and a lack of correlation between DNA adduct formation and induction of cellular lesions. We suggest that doses in the range of those reported can be used to study the contribution of epigenetic and genotoxic effects in carcinogenesis and to study threshold events.

In this report we describe the expression of IA-1 mRNA in a panel of 64 human lung cancer cell lines. IA-1 mRNA was detected by Northern blot analysis in 97% (30 of 31) of small cell lung cancer cell lines. In contrast, IA-1 mRNA was detected in only 13% (4 of 30) of non-small cell lung cancer cell lines. Nine of the 30 (30%) expressed either chromogranin A mRNA or produced L-dopa decarboxylase. Four of these 9 (44%) had detectable levels of IA-1 mRNA. In most of the lung cancer cell lines examined, IA-1 showed high concordance with the other neuroendocrine markers, L-dopa decarboxylase, and chromogranin A. The one exception was a variant small cell lung cancer cell line which expressed low or nondetectable levels of L-dopa decarboxylase. IA-1 is a candidate marker of neuroendocrine differentiation of human lung tumors. C1 USN,NATL MED CTR,NCI,NAVY ONCOL BRANCH,BETHESDA,MD 20889.

However, little is known about the mechanism by which bcl-2 overexpression inhibits apoptosis triggered by these agents. In this study, we examined whether bcl-2 overexpression could have effects on etoposide-induced DNA damage and its repair. For these experiments, we developed CH31 clones (mouse B-cells) stably transfected with human bcl-2 sense plasmids and compared these clones with a parental CH31 clone or CH31 clones with antisense plasmids. Overexpression of bcl-2 protein inhibited etoposide-induced apoptosis and cytotoxicity. However, there was no or little difference in the production and repair of DNA-protein cross-links, DNA single-strand breaks, and double-strand breaks among a parental CH31 clone and CH31 clones with human bcl-2 sense or antisense plasmids. These findings indicate that (a) apoptosis or cytotoxicity induced by etoposide can be separated into early events (formation of double-strand breaks, DNA single-strand breaks, and double-strand breaks) and later events (secondary DNA fragmentation or cell death) and (b) bcl-2 inhibits apoptosis and cytotoxicity induced by etoposide at some steps between these events.

To determine more precisely how TGF-alpha participates in multistep tumorigenesis of the liver, genotoxic (diethylnitrosamine or dimethylnitrosamine) and nongenotoxic (phenobarbital) chemical carcinogens were administered independently to TGF-alpha transgenic mice [line MT42 on a Crl:CD-1(ICR)BR background]. TGF-alpha overexpression dramatically accelerated carcinogen-induced hepatocarcinogenesis in MT42 males but not females. Interestingly, all three chemical agents were found to enhance strongly both hepatic tumor formation and progression in TGF-alpha transgenic male mice. In this study 100%, 90%, and 78% of transgenic males exposed to diethylnitrosamine, dimethylnitrosamine or phenobarbital, respectively, developed tumors between 24 and 32 weeks of age. Moreover, approximately 70% of tumor-bearing transgenic mice from each treatment group had hepatocellular carcinomas; no malignant lesions were found in any carcinogen-treated or untreated nontransgenic mice or in untreated MT42 mice at this age. These results demonstrate that chemical agents as diverse as nitrosamines and phenobarbital act as cocarcinogens with TGF-alpha in the livers of these transgenic mice, indicating that TGF-alpha possesses the unique ability to complement both initiation and promotion in hepatocarcinogenesis. Furthermore, because carcinogen-induced malignant conversion was restricted to transgenic mice, constitutive TGF-alpha overexpression may promote liver tumor progression as well.

This compound was tritiated, and its properties as a radioligand evaluated in rat brain membranes. Consistent with the high affinity and selectivity described for the non-radioactive form of this compound, saturation analyses of [H-3]ZG-63 binding to cerebellar diazepam-insensitive and other, diazepam-sensitive benzodiazepine receptors revealed K(d) values of 2.6 +/- 0.2 nM and 10.6 +/- 1.4 nM, respectively. The density (B(max)) of cerebellar diazepam-insensitive receptors labelled with [H-3]ZG-63 was not significantly different from values obtained with the prototypical diazepam-insensitive receptor ligand [H-3]Ro 15-4513, representing approximately 30% of total cerebellar benzodiazepine receptors. [H-3]ZG-63 also labelled cortical diazepam-sensitive benzodiazepine receptors, with B(max) values that were not significantly different from those obtained with [H-3]flunitrazepam. Diazepam-insensitive benzodiazepine receptors in rat cerebral cortex could be detected with [H-3]ZG-63, but the densities of these sites are a very minor component (less-than-or-equal-to 5%) of total benzodiazepine receptors. In the presence of GABA, [H-3]ZG-63 behaved as a 'gamma-aminobutyric acid (GABA) -positive', 'GABA-negative', and 'GABA-neutral' ligand at cortical diazepam-sensitive receptors, cerebellar diazepam-sensitive receptors, and cerebellar diazepam-insensitive benzodiazepine receptors, respectively. This profile differs from the prototype diazepam-insensitive receptor ligand, [H-3]Ro 15-4513. Competition studies demonstrated a very high correlation (r2 = 0.98; P < 0.002) between the potencies of a series of benzodiazepine receptor ligands to inhibit [H-3]ZG-63 and [H-3]Ro 15-4513 binding to cerebellar diazepam-insensitive receptors. The high affinity and selectivity of [H-3]ZG-63 for diazepam-insensitive receptors (diazepam-insensitive/diazepam-sensitive ratio of approximately 0.25) together with a GABA-shift profile which differs from Ro 15-4513 suggests that this compound may be useful in elucidating the function(s) of this benzodiazepine receptor subtype.

The gene encoding a protein (alphaA-CRYBP1) that specifically binds to the alphaA-CRYBP1RS sequence has been cloned from a cultured mouse lens cell line. In the present study, we have used an antibody (specific to the alphaA-CRYBP1 protein and made against a synthetic peptide) to directly identify UV-crosslinked protein-DNA complexes via a double-label immunoblotting technique. Multiple alphaA-CRYBP1 antigenically related proteins interacted with alphaA-CRYBP1RS in nuclear extracts from both a cloned mouse lens cell line (alphaTN4-1) that expresses alphaA-CRY and a mouse fibroblast line (L929) that does not express the gene. Two sizes (50 kDa and 90 kDa) of proteins reacting with the alphaA-CRYBP1-specific Ab were detected in both cell lines and, in addition, a > 200-kDa protein reacting with the Ab was unique to the fibroblast line. Thus, alphaA-CRYBP1 antigenically related proteins interact with alphaA-CRYBP1RS regardless of alphaA-CRY expression. Moreover, differential processing of the alphaA-CRYBP1 protein and/or alternative splicing of the alphaA-CRY transcript may affect expression of alphaA-CRY.

The differences cause substitutions of Val-7-->Gly (GTG-->GGT) and Met114-->Val (ATG-->GTG) and a G746 deletion in the 3' untranslated region. The analysis, by reverse transcriptase-polymerase chain reaction-direct sequencing, of BALB/c mouse placenta RNA revealed the same sequence in the placenta MnSOD as that from multiple mouse organs.

K+ depletion had no effect on the maximum insulin (0.7 muM)-stimulated transport rate but enhanced the sensitivity to insulin 3-fold (EC50= 0.05 versus 0.15 nM) by a mechanism that did not result from changes in the insulin receptor binding, autophosphorylation, or tyrosine kinase activity. Western blotting analysis revealed that K+ depletion induced a 2.2-fold increase in GLUT4 in plasma membranes from basal cells, enhanced the PMA-stimulated GLUT4 translocation by 4-fold, and increased the 5-fold insulin-stimulated GLUT4 translocation by 15%, indicating the presence of an inactive GLUT4 intermediate. The time course for insulin's stimulation of transport activity was accelerated by K+ depletion (t1/2 = 3 versus 1.5 min). Conversely, the reversal of transport activity, on removal of insulin, was delayed (t1/2 = 11 versus 22 min). The corresponding t1/2 values for the loss of GLUT4 were 22 min in control cells and 40 min in K+-depleted cells, again indicating the existence of an inactive intermediate. Photolabeling intact cells with the impermeant, exofacial photolabel 2-N-4-(1-azi-2,2,2-trifluoroethyl)benzoyl-1,3-bis(D-mannos-4-yloxy)-2-propylamine in the continuous presence of insulin revealed that K+ depletion had no effect on the GLUT4 externalization rate but halved the rate of internalization. K+ depletion elicited entirely analogous effects on the recycling of insulin-like growth factor II/mannose 6-phosphate receptor, strongly supporting the involvement of a coated pit mechanism in the recycling of GLUT4 transporters. An inactive conformation of GLUT4 has been detected in plasma membranes from insulin-stimulated cells, which is enhanced by K+ depletion, suggesting a limitation in the adipose cells' capacity to express active GLUT4 transporters.

To examine whether repression by chromatin proteins could contribute to the low level of Alu expression, a conserved Alu element from the fourth intron of the human alpha-fetoprotein gene was reconstituted with purified octamer or tetramer particles. Analysis of reconstitutes revealed that this Alu element directed translational and rotational positioning of octamers as well as tetramers. In vitro transcription experiments with reconstituted templates demonstrated that RNA polymerase III-dependent transcription of the Alu element was profoundly repressed by positioned octamer particles. Furthermore, complete CpG methylation of this template enhanced the capacity of tetramers to repress transcription. C1 NICHHD,MOLEC GROWTH REGULAT LAB,BLDG 6,RM 416,BETHESDA,MD 20892.

We have identified several discrete protein binding sites within this region of c-myc intron I designated as myc intron factor-1 (MIF-1), MIF-2, and MIF-3. In addition to our previous characterization of a 20-nucleotide binding site for MIF-1, we now have identified adjacent 20-nucleotide and 34-nucleotide binding sites for MIF-2 and MIF-3, respectively. All three elements are protected from exonuclease digestion by nuclear protein extracts, and each gives rise to a distinct migration pattern on mobility shift assays. In addition, MIF-1, 2, and 3 share a 5-nucleotide (TTATG) internal sequence, which may account for cross-competition of these binding sites in the exonuclease protection experiment. Deletion mutant analyses showed that selective removal of the MIF-3 binding site alone was sufficient to enhance chloramphenicol acetyltransferase reporter activity similar to that observed with larger deletions of myc intron I. We have demonstrated that somatic mutations in activated c-myc alleles are frequently clustered in discrete domains that define protein recognition sequences.

ZAP-70, a PTK of the p72syk family, associates with phosphorylated TCR subunits upon TCR stimulation. Here we report that the tandem SH2 domains of ZAP-70, expressed as a fusion protein, bind to tyrosine-phosphorylated CD3epsilon and TCRzeta from activated Jurkat T cell lysates. The single N- and C-terminal SH2 domains of ZAP-70, expressed separately, do not bind these TCR subunits. In comparison to fusion proteins containing SH2 domains from other proteins, the tandem SH2 domains of ZAP-70 demonstrate a remarkably restricted repertoire of protein binding, binding only TCRzeta and CD3epsilon. ZAP-70 is also recovered in the binding assay, but this is likely to be a consequence of its interaction with multiple SH2 binding sites on the zeta-zeta and CD3epsilon-containing dimers.

We report here isolation of a cDNA (I-19) encoding the B cell-derived protein recognized by NIM-R5 antibody. This cDNA contains an open reading frame that encodes a polypeptide of 304 amino acids with a predicted molecular weight of 34,500. The existence of a 22-amino acid hydrophobic region located 23 amino acids from the amino terminal of the deduced protein, together with four potential N-linked glycosylation sites, characterize the deduced protein encoded by I-19 cDNA as a typical type II transmembrane glycoprotein. Although I-19 cDNA appears to encode a novel murine protein, its nucleotide sequence and deduced amino acid sequence show approximately 70% homology to the previously reported sequence of human CD38, suggesting that I-19 cDNA encodes either the mouse homologue of CD38 or a closely related protein. Northern blot analysis of the expression of this cDNA product in a variety of cell types, together with immunoprecipitation of the recombinant protein expressed in BaF3 cells, indicated that I-19 cDNA encodes not only the epitope recognized by NIM-R5 but also a protein that is indistinguishable biochemically and in terms of distribution from the murine B cell activation marker recognized by NIM-R5 antibody. Chromosomal mapping studies have localized this locus to the proximal region of mouse chromosome 5. We anticipate that the availability of probes for the murine B cell activation marker recognized by NIM-R5, and the recombinant protein itself, will greatly aid efforts to define the role of this molecule in murine B cell development.

Intravenously administered LPS was reported to cause a sharp rise in serum NAP-1 concentration. Our study was designed to determine if LPS also caused an increase in MCP-1 and to measure associated changes in concentrations of antibody and immune complex. LPS caused a rise to a peak within 2 to 3 h in serum concentrations of free NAP-1 and MCP-1, followed by an almost equally rapid fall toward base-line levels by about 5 h postinjection. MCP-1 concentration in sera from the 11 subjects rose to a peak of 330 +/- 52 pM. The peak value for NAP-1 was 80 +/- 11 pM. In 10 of the 11 subjects, free IgG autoantibody to MCP-1 decreased from a mean pre-LPS value of 1820 +/- 660 pM to a mean low of 53% of the respective initial values. Corresponding data for IgG anti-NAP-1 were a pre-LPS concentration of 216 +/- 7 pM, which decreased to a mean low of 44% of the respective initial values. The finding in some subjects of a rapid rise in free antibody after the nadir suggests the possibility of acute regulation of autoantibody secretion rates. Although the results suggested that LPS-induced chemoattractant combined with free antibody, serum concentrations of MCP-1-IgG or NAP-1-IgG did not increase, which points to an as yet unknown mechanism for trapping and elimination of the immune complexes.

In the early phase of the disease, day 1 to 7, a retinal vasculitis is noted and is associated with the presence of virus particles. In the late phase of the disease, day 10 to 140, a retinal degeneration is observed and is associated with the absence of both virus particles and inflammatory cells. We show that the retinal degenerative process is also associated with the presence of antiretinal autoantibodies. In total, 22 of 23 sera collected from 10 to 70 days after JHM virus inoculation contained antiretinal autoantibodies. These autoantibodies are not found in sera from normal or mock-injected mice. Antibodies to retinal tissue were identified as two distinct patterns of immunoperoxidase staining on frozen sections of normal rat eyes, retinal autoantibodies and retinal pigment epithelium (RPE) autoantibodies. The antiretinal autoantibodies first appeared as IgM class antibodies that shifted to IgG class autoantibodies. The anti-RPE cell autoantibodies were predominantly of the IgG class. Sera that were positive for these autoantibodies did not stain with liver or kidney sections but 2 of 3 did react with rat brain sections. A second mouse strain, CD-1, was also evaluated because these animals respond to JHM virus inoculation by developing only the early phase of this disease, i.e. vasculitis. On day 10 postinoculation, the retina architecture has a normal appearance. In these mice, which are free of a retinal degeneration, antiretinal autoantibodies are not produced. However, just as is noted in the BALB/c mice, antivirus neutralizing antibodies are produced in the infected CD-1 mice. These findings suggest a role for autoimmunity in the pathogenesis of murine coronavirus induced retinal degeneration. This study establishes an animal model for the study of humoral autoimmune responses in human retinal degenerations. C1 GEORGE WASHINGTON UNIV, MED CTR, DEPT PATHOL, WASHINGTON, DC 20052 USA.

However, significant obstacles still limit the efficacy of this procedure. These include the occurrence of graft-versus-host disease, the failure of the marrow to engraft, the susceptibility of patients to opportunistic infections during the period of immunodeficiency after transplantation before full recovery of immune function, and finally, the recurrence of the cancer. Natural killer (NK) cells are lymphoid cells responsible for mediating a variety of immunologic and homeostatic functions. Initially described almost 20 years ago, the full range of functions carried out by these enigmatic cells continues to unfold. NK cells may be both beneficial and deleterious in bone marrow transplantation, depending on their genotype and activation status. Resting host-derived NK cells appear capable of mediating resistance to both autologous and allogeneic bone marrow cell grafts. At the other end of the spectrum, the transfer of activated NK cells of donor type appears to produce multiple beneficial effects during both syngeneic and allogeneic bone marrow transplantation. Here, we review and attempt to reconcile the literature concerning the basic biology of NK cells and their effects on hematopoiesis, both in vitro and in vivo. We also discuss the current issues in bone marrow transplantation and the potential role NK cells may play in determining the outcome of the marrow graft, the occurrence of graft-versus-host disease, and the generation of a graft-versus-tumor response when bone marrow transplantation is used for the treatment of cancer.

Vitamins and minerals in these foods may contribute to the reduced cancer risk. The people of Linxian County, China, have one of the world's highest rates of esophageal/gastric cardia cancer and a persistently low intake of several micronutrients. Purpose: We sought to determine if dietary supplementation with specific vitamins and minerals can lower mortality from or incidence of cancer as well as mortality from other diseases in Linxian. Methods: Individuals of ages 40-69 were recruited in 1985 from four Linxian communes. Mortality and cancer incidence during March 1986-May 1991 were ascertained for 29584 adults who received daily vitamin and mineral supplementation throughout this period. The subjects were randomly assigned to intervention groups according to a one-half replicate of a 24 factorial experimental design. This design enabled testing for the effects of four combinations of nutrients: (A) retinol and zinc; (B) riboflavin and niacin; (C) vitamin C and molybdenum; and (D) beta carotene, vitamin E, and selenium. Doses ranged from one to two times U.S. Recommended Daily Allowances. Results: A total of 2127 deaths occurred among trial participants during the intervention period. Cancer was the leading cause of death, with 32% of all deaths due to esophageal or stomach cancer, followed by cerebrovascular disease (25%). Significantly (P = .03) lower total mortality (relative risk [RR] = 0.91; 95% confidence interval [CI] = 0.84-0.99) occurred among those receiving supplementation with beta carotene, vitamin E, and selenium. The reduction was mainly due to lower cancer rates (RR = 0.87; 95% CI = 0.75-1.00), especially stomach cancer (RR = 0.79; 95% CI = 0.64-0.99), with the reduced risk beginning to arise about 1-2 years after the start of supplementation with these vitamins and minerals. No significant effects on mortality rates from all causes were found for supplementation with retinol and zinc, riboflavin and niacin, or vitamin C and molybdenum. Patterns of cancer incidence, on the basis of 1298 cases, generally resembled those for cancer mortality. Conclusions: The findings indicate that vitamin and mineral supplementation of the diet of Linxian adults, particularly with the combination of beta carotene, vitamin E, and selenium, may effect a reduction in cancer risk in this population. Implications: The results on their own are not definitive, but the promising findings should stimulate further research to clarify the potential benefits of micronutrient supplements.

In humans, epidemiologic evidence suggests that intake of fruits and vegetables may reduce risk of esophageal and other cancers. Vitamins and minerals in these foods may contribute to the reduced cancer risk. The people of Linxian, China, have persistently low intake of multiple nutrients and exhibit one of the world's highest rates of esophageal/gastric cardia cancer, with an exceptionally high risk of esophageal dysplasia. Purpose: To determine whether supplementation with multiple vitamins and minerals may reduce esophageal/gastric cardia cancer among persons with esophageal dysplasia, we conducted a 6-year prospective intervention trial in Linxian. Methods: Mortality and cancer incidence were ascertained from May 1985 through May 1991 for 3318 persons with cytologic evidence of esophageal dysplasia who were randomly assigned to receive, throughout that period, daily supplementation with 14 vitamins and 12 minerals or placebo. Doses were typically two to three times U.S. Recommended Daily Allowances. Compliance was assessed by counting unused pills monthly for all trial participants and by assaying nutrient levels in blood collected from samples of individuals randomly selected without replacement every 3 months throughout the trial. Cancers were identified through routine surveillance and by special cytology and endoscopy screenings after 21/2 years and 6 years. Results: A total of 324 deaths occurred during the 6-year intervention period; 167 occurred in the control (placebo) group and 157 occurred in the supplement group. Cancer was the leading cause of death (54% of all deaths); 18% were due to cerebrovascular diseases and 29% to other causes. Cumulative esophageal/gastric cardia death rates were 8% lower (relative risk [RR] = 0.92; 95% confidence interval [CI] = 0.67-1.28) among individuals receiving supplements rather than placebo, a nonsignificant (P>.10) difference. Risk of total mortality was 7% lower (RR = 0.93; 95% CI = 0.75-1.16; P>.10), total cancer 4% lower (RR = 0.96; 95% CI = 0.71-1.29; P>.10), cerebrovascular disease 38% lower (RR = 0.62; 95% CI = 0.37-1.06; P = .08), and other diseases 12% higher (RR = 1.12; 95% CI = 0.74-1.69; P>.10) among the treated group. Cumulative cancer incidence rates were nearly the same in the two groups. Conclusions: No substantial short-term beneficial effect on incidence or mortality for this type of cancer occurred following daily supplementation with multiple vitamins and minerals among adults with precancerous lesions of the esophagus. Implications: Although no statistically significant short-term benefits were observed, longer follow-up should be more informative about the effectiveness of this 6-year supplementation on cancer and other diseases among individuals with esophageal dysplasia.

The wild-type form of this protein functions to restrain inappropriate cellular proliferation. Approximately one half of human epithelial ovarian cancers have mutations in the p53 gene and overexpress the mutant protein product. Deletion of one allele of the p53 gene also frequently occurs in these cancers. Purpose: We sought to define the spectrum of mutations in the p53 gene in epithelial ovarian cancer with respect to both the specific codons involved and the type of mutations observed. We also examined the frequency of allelic deletion of the p53 gene in cancers containing p53 gene mutations. Methods: Tissue samples from the epithelial ovarian cancers of 62 patients were obtained during initial laparotomy. Histologic examination was done to ensure that the experimental samples used in this study contained more than 75% cancer cells. Total RNA was extracted from these samples and separately from matched control noncancerous regions of the surgical specimen or white blood cells. The purified RNAs were reverse transcribed to generate cDNA copies of exons 4-10 of the p53 gene. Two rounds of polymerase chain reaction (PCR) were conducted to produce enough template for DNA sequence analysis of the regions of interest within the p53 gene. Dideoxy sequencing of at least two independent productions of each amplified DNA template was done to confirm the validity of the mutations found. Allelic deletions were identified by PCR and gel electrophoretic techniques to examine three polymorphisms within the p53 gene in cancer-normal DNA pairs. Results: We identified 45 mutations in exons 5-8 of the p53 gene, where mutations frequently have been found in other cancer types. An additional mutation was identified in exon 4. Overall, 72% of the mutations were transitions, 24% transversions, and 4% microdeletions. Allelic deletion of the other p53 allele was seen in 67% of ovarian cancers in which a p53 mutation was present. Germ-line p53 mutations were not found in any patients whose cancers had p53 mutations. Conclusions and Implications: Like p53 mutations in other types of human cancers, those in epithelial ovarian cancers are diverse and occur frequently in exons 5-8. The predominance of transition mutations suggests that p53 mutations in ovarian cancer arise because of spontaneous errors in DNA synthesis and repair rather than the direct interaction of carcinogens with DNA. These molecular data are consistent with data from epidemiologic studies that have failed to demonstrate a convincing relationship between exposure to environmental carcinogens and the development of ovarian cancer.

Recently, our laboratory has demonstrated that IL-2Rgamma mutation results in X chromosome-linked severe combined immunodeficiency in humans, suggesting that IL-2Rgamma plays a vital role in thymic maturation of human T cells. We now report the isolation and characterization of cDNAs encoding murine IL-2Rgamma. The open reading frame encodes 369 aa, identical in length to that encoded by the human IL-2Rgamma cDNA. Murine IL-2Rgamma and human IL-2Rgamma have 69% and 70% identity at the nucleotide and amino acid levels, respectively. As expected, the murine IL-2Rgamma retains the WSXWS motif and four cysteine residues characteristic of cytokine receptor superfamily members. IL-2Rgamma mRNA distribution shows significant tissue specificity, with particularly high-level expression in spleen and thymus, and higher expression in single-positive (CD4+8- or CD4-8+)-enriched thymocytes than in double-negative (CD4-8-) thymocytes. Finally, we have localized the murine IL-2Rgamma gene, Il2rg, to the X chromosome between Rsvp and Plp and demonstrated that a defect in IL-2Rgamma is not responsible for the X chromosome-linked xid mutation, which maps to this same region. The cloning of the murine IL-2Rgamma cDNA will facilitate the investigation of the role of this protein in lymphocyte function and thymic development. C1 NIAID,MOLEC MICROBIOL LAB,BETHESDA,MD 20892.

Moreover, the exchange activity is constitutively enhanced in NIH 3T3 cells transformed by Src and ErbB2 oncogenic tyrosine protein kinases (TPKs), whereas transformation by oncogenic Mos and Raf does not alter the activity. GTPase-activating protein activity was not affected under these conditions. Overexpression of pp60c-Src mutants containing activated and suppressor TPK mutations resulted in stimulation and inhibition of the exchange factor activity, respectively. A TPK inhibitor, genistein, prevented the activation of the exchange factor in epidermal growth factor/platelet-derived growth factor-treated cells and src-transformed cells. Furthermore, the exchange factor activity bound to an antiphosphotyrosine antibody immunoaffinity column. These findings suggest that the guanine nucleotide exchange factor, but not GTPase-activating protein, plays a major role in the Ras activation in cell proliferation initiated by growth factor receptor TPKs and malignant transformation by oncogenic TPKs and that tyrosine phosphorylation of either the exchange factor or a tightly bound protein(s) may mediate the activation of the exchange factor by these TPKs.

The precursors to functional MHC class II molecules loaded with peptides are complexes of the invariant chain associated with class II alphabeta heterodimers. Targeting of newly synthesized MHC class II molecules to endosomes is mediated by the invariant chain, but the intracellular transport route is not known. This study demonstrates that in a human B-cell line a large population of MHC class II-invariant chain complexes reaches endosomes by rapid internalization from the cell surface. Quantitation of cell surface MHC class II-invariant chain complexes and of their surface half-life revealed that 3000 complexes internalized per minute into endosomes. This highly efficient endocytosis was mediated by the cytoplasmic tail of the invariant chain. After internalization, the invariant chain dissociated from the MHC class II-invariant chain complexes. This pathway may represent an important mechanism for loading class II molecules with immunogenic peptides from several endocytic compartments. C1 UNIV OSLO,DEPT BIOL,N-0316 OSLO,NORWAY.

Although many cells respond equivalently to all three isoforms, certain cells respond selectively. Using chimeric proteins in which selected regions of the different isoforms were interchanged, we have identified two distinct functional domains of TGF-beta involved in determining the biological potencies and functions of the molecule. The first domain is important for determining whether TGF-beta can be sequestered by alpha2-macroglobulin. By replacing aa 45 and 47 of TGF-beta2 with the corresponding amino acids of TGF-beta1, sequestration of the TGF-beta molecule by alpha2-macroglobulin was markedly reduced. The second domain is functionally different from the alpha2-macroglobulin sequestration site and is important for determining the potency of TGF-beta to inhibit growth of the LS513 human colorectal cancer cell line. Neither the TGF-beta2/beta1-(40-47) replacement construct nor a chimera containing aa 1-39 of TGF-beta2, aa 40-82 of TGF-beta1, and aa 83-112 of TGF-beta2 was equivalent to TGF-beta1 in inhibiting growth of LS513 cells. This fact suggests that additional amino acids outside of the aa 40-82 region are required to specify TGF-beta1 activity with these cells. C1 NIH,CHEMOPREVENT LAB,BETHESDA,MD 20892.

We have found that this elevation is reflected by increased levels of beta-APP mRNA. The induction is rapid (occurring 60 min after placement of the lesion) and persistent (remaining for at least 45 days after lesioning). Two other subcortical lesions, which result in reductions of cortical adrenergic and serotonergic innervation, similarly induced cortical beta-APP. The beta-APP induction is reversible and does not require loss of the subcortical neurons. Infusion of lidocaine, a calcium antagonist that disrupts neurotransmitter release, into the nucleus basalis of Meynert leads to the temporary reduction of released acetylcholine in the cortex. In this model, beta-APP mRNA levels are elevated shortly after the infusion of lidocaine (90 min) but return to preinfusion levels 7 days after the lidocaine treatment. However, metabolic stresses of the brain, including chronic physostigmine, glucocorticoid, and diabetogenic treatments, fail to induce the beta-APP response. These results suggest that the induction of beta-APP is a specific response to the loss of functional innervation in the cortex.

The HNE-specific antibody was prepared by immunizing rabbits with a HNE-keyhole limpet hemocyanin conjugate and purifying the rabbit serum on an affinity gel prepared by covalent attachment of a HNE-conjugated heptapeptide. When various preparations of glyceraldehyde-3-phosphate dehydrogenase containing 0-7.0 equivalent of HNE-histidine residues per subunit were obtained by incubating samples of glyceraldehyde-3-phosphate dehydrogenase with increased amounts of HNE and subjected to immunoblotting with the HNE-specific antibody, the intensities of the blots were directly proportional to the number of HNE-histidine adducts as measured directly by amino acid analysis. Binding of the HNE-conjugated glyceraldehyde-3-phosphate dehydrogenase to the HNE-specific antibody could be completely inhibited by HNE-N-acetylhistidine, HNE-N-acetyllysine, or HNE-glutathione, suggesting that the antigenic determinant recognized by the antibody is the HNE moiety, not the HNE-amino add conjugates, such as HNE-histidine, HNE-lysine, and HNE-cysteine. The utility of the HNE-specific antibody was demonstrated by its ability to react selectively with a number of HNE-protein adducts in immunoblot analyses of crude homogenates of rat liver hepatocytes that had been exposed to HNE or oxidative stresses with tert-butylhydroperoxide or metal-ion-catalyzed oxidation systems.

In this paper we examine the limitations of standard time varying Cox proportional hazards models to yield tests and estimates of this effect. Implementing the method of G-estimation proposed by Robins, we perform an observational analysis of data from the Multiple Risk Factor Intervention Trial (MRFIT) and estimate the causal effect of cigarette cessation while controlling for such time varying confounders as angina. We reject the null hypothesis of no effect of quitting on time to failure, and estimate that by quitting smoking, an individual increases by 50 per cent his time to death or first myocardial infarction (MI).

Such designs may offer impressive gains in efficiency compared with a series of trials studying one treatment at a time. This is especially true when the treatments do not interact with one another. If interactions are of special interest, factorial designs provide one sensible approach for studying them, but larger sample sizes would be required because tests for interactions have lower power than those for main effects. In trials designed to test putative agents for preventing cancer, interactions may be of less interest so that fractions of higher-order factorial designs might be appropriate. Sometimes it may not be reasonable, interesting, feasible, or ethical to study all treatment combinations required in a complete or fractional factorial design, yet one may want to preserve some of the factorial structure to increase efficiency and to aid understanding. For such situations, incomplete factorial designs are proposed. Although not all of the advantages of full factorial designs are preserved, such designs may provide reasonable compromises for certain situations.

Highest ANP binding was observed in the cortical neuroepithelium at embryonic day 17. Lower ANP binding was found in cingulate and frontal cortices at postnatal day 10, but none was detectable at 8 weeks of age. In the neuroepithelium of the embryonic rat, binding was displaced with a potency of rat ANP-(1-28) (rANP) > porcine type-C natriuretic peptide (pCNP-22) = rat ANP fragment C-ANP-(4-23) (rC-ANP-(4-23)) = rat brain natriuretic peptide (rBNP-32), different from that of any of the well-characterized (ANP(A), ANP(B), and ANP(C)) natriuretic peptide receptors. The present results support the hypothesis of a role for ANP during brain maturation and indicate that the ANP receptors highly expressed in the embryonic neuroepithelium may belong to a new ANP receptor subtype not yet characterized.

Consistent with previous reports, rats in the pentobarbital, ethanol, and diazepam training conditions all showed complete dose-dependent generalization to pentobarbital under test conditions, but rats trained to discriminate lorazepam did not. Administration of the neuroactive steroids 3alpha,21-dihydroxy-5alpha-pregnan-20-one (3alpha,5alpha-THDOC) and 3alpha-hydroxy-5alpha-pregnan-20-one (3alpha,5alpha-P) also produced complete generalization in rats trained to discriminate pentobarbital, ethanol, and diazepam, but not in rats trained to discriminate lorazepam. These results further indicate the specificity of the lorazepam training condition and are consistent with neurochemical data indicating that these neuroactive steroids are similar to barbiturates in modulating gamma-aminobutyric acid (GABA)A receptors. In the context of previous data, the results from the four training groups suggest that the discriminative-stimulus effects of the neuroactive steroids are sedative/anxiolytic in nature and probably mediated through a non-benzodiazepine GABA(A) site.

The ability of IFN-gamma to inhibit replication of ectromelia, vaccinia, and herpes simplex-1 viruses in mouse macrophages correlated with the cells' production of nitric oxide (NO). Viral replication was restored in IFN-gamma-treated macrophages exposed to inhibitors of NO synthase. Conversely, epithelial cells with no detectable NO synthesis restricted viral replication when transfected with a complementary DNA encoding inducible NO synthase or treated with organic compounds that generate NO. In mice, an inhibitor of NO synthase converted resolving ectromelia virus infection into fulminant mousepox. Thus, induction of NO synthase can be necessary and sufficient for a substantial antiviral effect of IFN-gamma.

We examined changes in incidence of selected cancers in women aged 20-49 years and compared groups differing in incidence of AIDS. Black women were compared to white women in New York City and in the remainder of New York State; for cervical cancer, rates were also compared for Blacks and Whites in northern New Jersey. The incidence of Kaposi's sarcoma in women increased in New York City, beginning in 1982 for Blacks and in 1984 for Whites, but remained stable in the remainder of New York State. The incidence of non-Hodgkin's lymphoma in New York women doubled in Blacks after 1982 whereas incidence trends in Whites were unchanged. No consistent variation was seen in the incidence of Hodgkin's disease. Cervical cancer in New York and northern New Jersey Blacks declined over the same period by approximately 40% for invasive tumors and 50% for in situ lesions. The HIV epidemic is associated with substantial excesses of Kaposi's sarcoma and non-Hodgkin's lymphoma in women. The absence of Kaposi's sarcoma in upstate New York women suggests the existence of a geographically restricted co-factor(s) for Kaposi's sarcoma in addition to HIV. If HIV affected cervical cancer incidence through 1988, its impact was small compared to the striking decreases which followed widespread adoption of Papanicolaou screening. (C) 1993 Wiley-Liss, Inc.

Six clones (IFN-gamma clones) releasing between 2 and 6,000 international units (IU) of IFN-gamma/ml culture medium, were compared to TS/A parental cells (TS/A-pc) and to cells transfected with neomycin resistance gene only (NEO cells). Autocrine IFN-gamma up-regulated membrane expression of H-2 class-1 and Ly-6 glycoproteins, but did not alter cellular proliferation in vitro. All IFN-gamma clones gave rise to progressive tumors with a growth rate significantly slower than that of tumors induced by TS/A-pc and NEO cells, and inversely correlated with the amount of IFN-gamma secreted. TS/A-pc and NEO tumors displayed a marginal reactive infiltrate, whereas those formed by IFN-gamma clones were massively infiltrated mostly by macrophages. In T- and NK-deficient mice the growth of tumors formed by IFN-gamma clones was not enhanced. In vitro tests showed that IFN-gamma clone cells were markedly more lysed by macrophages than TS/A-pc and NEO cells, while they remained poorly sensitive to NK and LAK cells. These data as a whole suggest that the development of solid tumors by IFN-gamma clones is primarily hampered by macrophages and not by T-lymphocytes or NK cells. When spontaneous metastatic ability was compared, 2 IFN-gamma clones releasing 2-4 IFN-gamma IU/ml were significantly more metastatic, while most IFN-gamma clones appeared to be as metastatic as NEO cells. By contrast, following intravenous challenge, all IFN-gamma clones produced 5-10 times more experimental metastases than NEO cells. The higher metastatic ability of IFN-gamma clones was attributed to increased resistance to NK cells since, in NK-depleted BALB/c mice, metastatic spread of IFN-gamma clones was not enhanced, whereas a 50-fold increase in the number of metastases was found upon injection of NEO cells.

Design.- A cross-sectional study using data from the 1991 National Household Survey on Drug Abuse. Study Population.- The survey covered the population aged 12 years and older living in households in the United States. The results of the survey were based on personal interviews combined with self-administered questionnaires from 32 594 respondents. These respondents were randomly selected by means of a stratified multistage area sample of the household population. Results.- Estimates based on data from the National Household Survey on Drug Abuse indicated that there are more than 1 million current or former AAS users in this country, with more than half of the lifetime user population being 26 years of age or older. More than 300 000 individuals used AAS in the past year. Males had higher levels of AAS use during their lifetime than females (0.9% and 0.1%, respectively; P<.01). The median age of first use of AAS for the study population was 18 years; for 12- to 17-year-olds, the median age of initiation was 15 years. Among 12- to 34-year-olds, AAS use was significantly and positively associated with the use of other illicit drugs (P<.05), cigarettes (12- to 17-year-olds only; P<.01), and alcohol (P<.01). Furthermore, AAS use is highly correlated with self-reported aggressive behavior (P<.01) and crimes against property (P<.01). Conclusions.- These results indicate that AAS use impacts a large number of men and women from various racial and age groups across the nation. While causal inferences cannot be made regarding the associations between AAS use and use of other drugs as well as antisocial behavior, these findings should enhance our ability to profile the typical AAS user.

Several polar carotenoids, 2',3'-anhydrolutein, alpha-cryptoxanthin, and geometric isomers of lycopene and beta-carotene are also separated. Retinoids and carotenoids are monitored using a programmable ultraviolet-visible detector, while tocopherols are monitored using a fluorescence detector. The method uses a gradient containing acetonitrile, methanol, and ethyl acetate. Ammonium acetate is introduced with the methanol to minimize carotenoid losses on the LC column aggravated by the use of acetonitrile and ethyl acetate. The method is also applicable to the analysis of foods. C1 NCI,DIV CANC ETIOL,ENVIRONM EPIDEMIOL BRANCH,BETHESDA,MD 20892.

In the present study, inhibition of protein kinase C with calphostin C or stauroporine or prolonged treatment with the phorbol ester TPA decreased phosphorylation of P-glycoprotein, and impaired transport of vinblastine. Calphostin C also inhibited transport of actinomycin D, vincristine, rhodamine, and azidopine in SW620 Ad300 multidrug-resistant human colon carcinoma cells. Photoaffinity labeling of P-glycoprotein with azidopine was decreased by calphostin C, suggesting that dephosphorylation alters the affinity of P-glycoprotein for its substrates. Impaired transport of rhodamine in normal T lymphocytes treated with staurosporine demonstrates that modulation of P-glycoprotein function is not limited to cells selected for drug resistance in vitro. Transport of P-glycoprotein antagonists in SW620 Ad300 cells was also affected by calphostin C. Cyclosporin A transport decreased, while verapamil transport increased. Cyclosporin A in calphostin C-treated cells resulted in additive P-glycoprotein antagonism, while no additive effect could be demonstrated with verapamil, suggesting that the increase in verapamil transport makes it a poorer P-glycoprotein antagonist. These studies suggest that transport by P-glycoprotein is a dynamic process which can be modulated by phosphorylation, and that antagonists may block P-glycoprotein differently in different phosphorylation states.

The open reading frame (3324 base pairs) of RcGIP1 encodes 1108 amino acids, including a hydrophobic membrane-association domain in the NH2-terminal portion and, in the COOH-terminal portion, a putative catalytic domain conserved among all mammalian PDEs which is preceded by a putative regulatory domain that contains three consensus cAMP-dependent protein kinase phosphorylation sites and followed by a hydrophilic COOH-terminal domain. The carboxyl-terminal portion including the conserved domain was expressed as a glutathione S-transferase fusion protein and exhibited cAMP PDE activity which was inhibited by cilostamide, a specific cGI PDE inhibitor. RcGIP1 cDNA hybridizes strongly with RNA from isolated adipocytes, and its mRNA increases dramatically during differentiation of 3T3-L1 adipocytes. The deduced sequence of the second partial cDNA clone (RcGIP2 clone 53B) is highly homologous to the corresponding region of human cardiac cGI PDE cDNA. RcGIP2 cDNA hybridized strongly with rat cardiac tissue RNA and weakly if at all with RNA from rat adipocytes or 3T3-L1 fibroblasts or adipocytes. We suggest that RcGIP1 represents the hormone-sensitive, membrane-associated rat adipocyte cGI PDE and RcGIP2, a cGI PDE from vascular elements in rat adipose tissue.

We have used DNase I footprinting with K562 erythroleukemia cell extracts to identify protein components of the minimal LCR element, hypersensitive site 2. Six major regions of protection were observed, and the occupation of two regions (sites II and V) was strongly temperature-dependent. Fractionation of K562 nuclear proteins revealed a single major protein that bound tightly to site II. An E-box was necessary for high affinity binding to DNA. We used antibodies and recombinant USF protein to prove that the helix-loop-helix transcription factor USF is the only detectible component in K562 cells that binds to this site. Despite significant differences between site II and a canonical USF-binding site, the USF binding affinity was comparable for the two sites. In both cases the interaction with the E-box of either wild-type USF or a approximately 15-kDa minimal USF DNA binding polypeptide displays an unusual positive temperature dependence, consistent with the observed footprinting behavior. The results show that a relatively ubiquitous factor, not confined to erythroid cells, is an important part of the complex of proteins bound at hypersensitive site 2 of the LCR in K562 cells.

Rats with unilateral 6-hydroxydopamine lesions of the SN received intrastriatal kainic acid lesions or sham lesions, and then received fetal (E16) SN or sciatic nerve grafts in the lateral ventricle. The depth of reafferentation of the striatum by catecholaminergic neurites from SN grafts was significantly increased in rats with kainic acid-induced striatal lesions, as compared to the sham-lesioned controls. No reafferentation was seen in the control animals with sciatic nerve grafts. These data suggest that striatal injury promotes the growth of dopaminergic neurites from SN grafts.

GM1 is a natural compound that is able to prevent neuron degeneration induced by exposure to excitatory amino acids in vitro and by ischemia or neurotoxins in vivo. GM1 30 mg/kg, a dose very effective in preventing excitatory amino acid-induced neurotoxicity, produced minimal rCMRglc change over a 6 h period. GM1 150 and 300 mg/kg reduced rCMRglc, in 14 (31%) and in 29 (64%) brain regions, respectively. Maximal metabolic effects occurred in hippocampal areas which possess, in specific subfields, the highest brain concentrations of different excitatory amino acid receptor subtypes. This finding suggests an effect by GM1 on postreceptor mechanisms common to different excitatory amino acids. C1 CLIN MALATTIE NERVOSE & MENTALI, PADUA, ITALY. CLIN PSICHIAT 1, PISA, ITALY.

In contrast, an aryl p-(trifluoromethyl) substituent has little effect on affinity of 3,7-disubstituted and 1,3,7-trisubstituted 8-phenylxanthines. An aryl p-sulfo substituent reduces affinity of all 8-phenylxanthines at A1-and A2a-adenosine receptors. An 8-(trifluoromethyl) substituent markedly reduces affinity of 1,3-dialkylxanthines at both A1- and A2a-adenosine receptors. In contrast, 8-(trifluoromethyl)caffeine retains affinity for A2a-adenosine receptors, but does lose affinity for A1-adenosine receptors. 8-Bromo-, 8-acryl-, and 8-pent-1-enylcaffeines are also selective for A2-adenosine receptors, while 8-cyclobutylcaffeine is nonselective. 8-[trans-2-(tert-butyloxycarbonyl)vinylcaffeine is 20-fold selective for Aza vs A1 receptors.

In both structures, the 2-hydroxypropyl group is inserted into the macrocyclic cavity of the next molecule related by the two-fold screw axis, and a helically extended polymeric structure is formed by repetition of the intermolecular inclusion. The hydroxyl group of the substituent group penetrates through the macrocyclic ring from the secondary hydroxyl side and is linked to an HO-6 group by a hydrogen bond. Comparison of intermolecular contacts of the substituent group indicates that the (S)-2-hydroxypropyl group is better fitted to the cavity than the (R)-2-hydroxypropyl group.

It is isolated as a soluble protein from the lumen of the microsomal fraction of liver and intestine4. The large subunit of MTP was not detectable in four unrelated subjects with abetatipoproteinaemia5, a rare autosomal recessive disease characterized by a defect in the assembly or secretion of plasma lipoproteins that contain apolipoprotein B (ref. 6). We report here the isolation and sequencing of complementary DNA encoding the large subunit of MTP. A comparison of this sequence to corresponding genomic sequences from two abetatipoproteinaemic subjects revealed a homozygous frameshift mutation in one subject and a homozygous nonsense mutation in the other. The results indicate that a defect in the gene for die large subunit of MTP is the proximal cause of abetalipoproteinaemia in these two subjects, and that MTP is required for the secretion of plasma lipoproteins that contain apolipoprotein B.

Methods: Eight rhesus monkeys were inoculated in the saphenous vein with SIV(sm). Four animals were maintained as uninoculated controls. CSF and blood samples were obtained every 1-4 weeks over the course of study. SIV isolation was determined in H9 cells for the CSF and in primary rhesus lymphocyte co-cultures for peripheral blood mononuclear cells (PBMC). QUIN was quantitated in CSF and serum by electron-capture negative chemical ionization gas chromatography mass spectrometry. Results: All SIV-inoculated animals became CSF and PBMC isolation-positive by 1-3 weeks post-inoculation. Control animals remained SIV-negative. One SIV-positive animal was humanely euthanized at 2 weeks post-inoculation. The three SIV-inoculated animals that were CSF isolation-negative after the fifth week post-inoculation maintained CSF QUIN values < 100 nM, remained CSF and PBMC isolation-negative, and clinically healthy in the chronic course of disease. In contrast, the four SIV-inoculated animals that were CSF isolation-positive 6-8 weeks post-inoculation had CSF QUIN levels as high as 153-565 nM during the second month post-inoculation and remained CSF virus isolation-negative, persistently PBMC isolation-positive, and experienced clinical symptoms of SIV in the chronic course of disease. Three of these four animals have succumbed to SIV infection. Discussion: Initial QUIN responses and viral isolation status in the first month post-inoculation were consistent among SIV-inoculated animals with CSF and serum QUIN values significantly higher than those of controls. A divergence within the SIV-inoculated group of animals became apparent within the second month of primary SIV infection and was maintained throughout the course of infection. Persistent PBMC viral isolation and marked elevations of QUIN were linked to symptomatic disease and a poor prognosis for survival. Predominantly negative PBMC viral isolation and slight, but significant, elevations of QUIN were linked to asymptomatic disease with a favorable prognosis for survival.

Setting: Mama Yemo Hospital and University Hospital morgues in Kinshasa, and Karawa Hospital in Equateur Region, Zaire. Methods: Autopsy cases with a clinical diagnosis of AIDS on the death certificate or chart were studied. Evaluation included post-mortem HIV-1 serology, chart review for specific AIDS-related symptoms and signs, and application of WHO and CDC case criteria to the clinical and autopsy diagnoses. Results: Of the 68 diagnosed AIDS cases, 98% fulfilled WHO criteria for AIDS and 93% fulfilled both WHO and CDC criteria. All cases fulfilling both criteria were HIV-1-seropositive. Opportunistic infections accounted for 84% of CDC AIDS-defining conditions. Disseminated tuberculosis was the most frequent (41%) specific diagnosis; Pneumocystis carinii pneumonia was rare (<2%). Conclusions: There was good concordance between WHO and CDC case definitions. A diagnosis of AIDS on the chart or death certificate is adequate for surveillance purposes in this population.

The first phase of the study included 61 HIV-1+ AIDS-free subjects 4 years (+/- 6 months) postseroconversion and 75 contemporaneous uninfected subjects. Two years later, a subset of 35 HIV-1+ AIDS-free subjects and 72 HIV-1 controls was examined. Mean 90K levels for HIV-1+ subjects were significantly higher than for contemporaneous HIV-1- subjects both 4 and 6 years postseroconversion (p < 0.0001). A significantly more rapid progression to AIDS was seen in HIV-1+ subjects with high 90K levels both 4 years (p = 0.01) and 6 years (p = 0.003) postseroconversion. Four years postseroconversion, 90K was significantly correlated with CD8 cell percent, interferon, neopterin, and beta2-microglobulin (p < 0.05). Two years later, significant correlations were seen between 90K levels and CD4 cell percent, CD4 cell number, and beta2-microglobulin (p < 0. 05). Stepwise-stepdown regression modeling using 90K, CD4 cell percent, interferon, and beta2-microglobulin levels 4 years postseroconversion showed that the predictive value of a trivariate model of 90K-interferon-CD4 percent was better than any univariate or bivariate model. We conclude that the 90K protein may be a useful predictor of progression to AIDS in HIV-1+ patients, particularly in combination with the established markers of CD4 cell percent and interferon.

It differs from the related HIV-1 Tat in certain aspects of its structure and function. HIV-2 Tat is composed of 130 amino acids versus 86 amino acids for HIV-1 Tat. Apart from certain conserved regions, there is little homology between the two Tats. They also differ in their ability to trans-activate HIV-2 and HIV-1 long terminal repeat (LTR)-directed gene expression. As an aid to understanding its mechanism of action, the functional domains important for HIV-2 Tat trans-activation of HIV-2 and HIV-1 LTR-directed gene expression were investigated. Like HIV-1 Tat, HIV-2 Tat contains conserved cysteine- and arginine-rich domains important for its function. However, HIV-2 Tat differs from HIV-1 Tat in that about 20% of the HIV-2 Tat at the amino terminus was not essential for its trans-activation function while HIV-1 Tat amino terminus is reportedly a part of its activation domain. Similarly, about 30% of the protein at the carboxy terminus of HIV-2 Tat was not essential. A domain critical for HIV-2 Tat-mediated trans-activation was located just upstream of the cysteine-rich domain. This segment is predicted to adopt an alpha-helical conformation and also contains acidic amino acid residues; thus, it may resemble amphipathic helix-type activation domains found in some transcriptional factors. A region with predicted hydrophobic alpha-helical character located between the cysteine- and arginine-rich domains was also important for HIV-2 Tat function. HIV-2 Tat mutants that were analogs of HIV-1 Tat trans-dominant negative mutants did not display such a phenotype.

The major goals of this scientific meeting were to bring together researchers and infectious disease specialists who have expertise in primary HIV-1 infection (PHI) to review the pathogenesis of PHI, the treatment experience of PHI in humans and of early retroviral infection in animal models, and to devise theoretical and operational strategies for future clinical trials relating to therapeutic intervention of PHI. The proceedings of this workshop are timely and serve to further the development of innovative strategies for the treatment of HIV-1 infection.

The FMF gene (designated ''MEF'') is on 16p, with the gene order 16cen-D16S80-MEF-D16S94-D16S283-D16S291-16pter. Here we report the association of FMF susceptibility with alleles at D16S94, D16S283, and D16S291 among 31 non-Ashkenazi Jewish families (14 Moroccan, 17 non-Moroccan). We observed highly significant associations at D16S283 and D16S291 among the Moroccan families. For the non-Moroccans, only the allelic association at D16S94 approached statistical significance. Haplotype analysis showed that 18/25 Moroccan FMF chromosomes, versus 0/21 noncarrier chromosomes, bore a specific haplotype for D16S94-D16S283-D16S291. Among non-Moroccans this haplotype was present in 6/26 FMF chromosomes versus 1/28 controls. Both groups of families are largely descended from Jews who fled the Spanish Inquisition. The strong haplotype association seen among the Moroccans is most likely a founder effect, given the recent origin and genetic isolation of the Moroccan Jewish community. The lower haplotype frequency among non-Moroccan carriers may reflect differences both in history and in population genetics.

Restriction analysis of 101 human samples revealed the frequency of the rare allele to be 0% (n = 69) in Caucasians and 4.7% (3/64, n = 32) among African-Americans. To investigate the consequence of this amino acid substitution, a cDNA construct (p53 mut47ser) containing the mutation was introduced into a lung adenocarcinoma cell line (Calu-6) that does not express p53. A growth suppression similar to that obtained after introduction of a wild-type p53 cDNA construct was observed, in contrast to the result obtained by introduction of p53 mut143ala. Furthermore, expression of neither p53 mut47ser nor wild-type p53 was tolerated by growing cells. In transient expression assays, both mut47ser and wild-type p53 activated the expression of a reporter gene linked to a p53 binding sequence (PG13-CAT) and inhibited the expression of the luciferase gene under the control of the Rous sarcoma virus promoter (RSVluc). In the same assay, mut143ala did not activate the expression of PG13-CAT and produced only a slight inhibitory effect on RSVluc. These findings indicate that the p53 variant with a serine at codon 47 should be considered as a rare germ-line polymorphism that does not alter the growth-suppression activity of p53.

They are most often cause by mutations in the phenylalanine hydroxylase gene and, less frequently but with usually more serious consequences, in genes necessary for the synthesis and regeneration of the cofactor, tetrahydrobiopterin. This cofactor is absolutely required for all aromatic amino acid hydroxylations, and, recently, nitric oxide production from L-arginine has also been found to be dependent on tetrahydrobiopterin. Phenylalanine hydroxylase catalyzes a coupled reaction in which phenylalanine is converted to tyrosine and in which tetrahydrobiopterin is converted to the unstable carbinolamine, 4a-hydroxytetrahydrobiopterin. The enzyme, carbinolamine dehydratase, catalyzes the dehydration of the carbinolamine to quinonoid dihydropterin. A decreased rate of dehydration of this compound has been hypothesized to be responsible for the production of 7-biopterin found in certain mildly hyperphenylalaninemic individuals. We have now identified nonsense and missense mutations in the 4a-carbinolamine dehydratase gene in a hyperphenylalaninemic child who excretes large amounts of 7-biopterin. This finding is consistent with the role of the carbinolamine dehydratase in the phenylalanine hydroxylation reaction. Together with previously identified inherited disorders in phenylalanine hydroxylase and dihydropteridine reductase, there are now identified mutations in the three enzymes involved in the phenylalanine hydroxylation system. In addition, the genetics of this system may have broader implications, since the product of the dehydratase gene has previously been shown to play an additional role (as dimerization cofactor for hepatocyte nuclear factor-1alpha) in the regulation of transcription, through interaction with hepatocyte nuclear factor-1alpha.

METHODS: A culture for Sporothrix schenckii or compatible histopathology was required for inclusion in the study. Patients with both cutaneous and systemic sporotrichosis were treated. Patients received from 100 to 600 mg of itraconazole daily for 3 to 18 months. Patients were classified as responders or nonresponders. Responders were further classified as remaining on treatment, relapsed, or free of disease. Nonresponders included patients who failed to respond or progressed during treatment with itraconazole. RESULTS: Twenty-seven patients (mean age: 53 years) were treated with 30 courses of itraconazole. Diabetes mellitus and alcoholism were present in eight and seven patients, respectively. Sites of involvement included lymphocutaneous alone in 9 patients, articular/osseous in 15 (multifocal in 3), and lung in 3. Prior therapy was unsuccessful in 11 patients. Among the 30 courses, there were 25 responders and 5 nonresponders. All 5 nonresponders received at least 200 mg daily of itraconazole for durations that ranged from 6 to 18 months. Of the 25 responders, 7 relapsed 1 to 7 months after treatment durations of 6 to 18 months. Of the 7 who relapsed, 2 are responding to a second course. One responder was lost to follow-up after 10 months of treatment with itraconazole. Of the re 17 responders, 3 remain on treatment, and 14 are free of disease over follow-up durations of 6 to 42 months (mean: 17.6 months). Itraconazole was well tolerated with few side effects noted. CONCLUSIONS: These results document the efficacy of itraconazole in the treatment of cutaneous and systemic sporotrichosis. C1 AUDIE L MURPHY MEM VET ADM MED CTR,SAN ANTONIO,TX 78284.

METHODS: Using a previously described classification system, we prospectively classified venous anatomy bilaterally in 135 of 136 persons consecutively undergoing inferior petrosal sinus sampling. RESULTS: Type IV anatomy, with no anastomosis between the inferior petrosal sinus and the internal jugular vein, was significantly less frequent in our series than in a previous series (1 versus 7%; P < .001). Venous anatomy did not differ significantly between the left and the right junctions or between men and women. Venous anatomy was symmetric in only 65% of subjects (86 of 133). We describe an uncommon variant anatomy, incomplete type IV, found in 4.5% of our subjects (six of 133), that may cause incorrect results of petrosal sinus sampling. CONCLUSION: Bilateral sampling of pituitary venous effluent can be accomplished by the methods described, despite the presence of either incomplete or true type IV venous anatomy. Bilateral petrosal sinus sampling is anatomically possible in 99% of persons. C1 NIH,WARREN GRANT MAGNUSON CLIN CTR,DEPT DIAGNOST RADIOL,BETHESDA,MD 20892.

A secondary hypothesis addressed in this article was that screening ultrasonography would have a favorable impact on maternal management or outcome. STUDY DESIGN: Pregnant women without a specific indication for ultrasonographic examination in early pregnancy were randomly assigned to have either two screening sonograms or conventional obstetric care. Pregnancy interventions and maternal outcomes were compared in the two groups. RESULTS: No significant differences were found in maternal outcomes. Use of ultrasonography was markedly higher in the screened group. The rates of induced abortion, amniocentesis, tests of fetal well-being, external version, induction, and cesarean section and the distribution of total hospital days were similar in the two groups. Use of tocolytics and the rate of postdate pregnancy were both slightly lower in the screened group. CONCLUSION: Screening ultrasonography resulted in no clinically significant benefit.

STUDY DESIGN: Two genetic trapping reporter constructs that lack transcriptional regulatory sequences were introduced independently into transcriptionally active gene loci by electroporation into mouse embryonic stem cells. Patterns of host gene-reporter construct expression were investigated in differentiated embryonic stem cells, embryoid bodies, and chimeric embryos at various stages of development. RESULTS: Three patterns of host gene-reporter construct expression were observed from the developmental analysis of four vector-integrated cell lines. Reporter expression patterns reflecting developmental regulation, constitutive activity, and developmental inactivation of the host genes were observed. CONCLUSIONS: Two vector-integrated gene loci from cell lines CCE-1C1 and D3-B44 have expression patterns not previously described by genetic trapping. Molecular characterization of these interrupted genes will shed light on their developmental function. C1 NICHHD,MAMMALIAN GENES & DEV LAB,DEV GENE REGULAT SECT,BETHESDA,MD 20892.

To determine whether alteration of the p53 gene is an early event in endometrial carcinogenesis, we examined the p53 gene in endometrial hyperplasias. STUDY DESIGN: Genomic deoxyribonucleic acid was extracted from 117 endometrial hyperplasias (36 simple, 40 complex, 41 atypical) and 30 endometrial cancers. Exons 5 through 8 of the p53 gene were amplified by means of the polymerase chain reaction. Mutations in the p53 gene were sought with single-stranded conformation polymorphism analysis and confirmed by direct deoxyribonucleic acid sequencing. RESULTS: None of 117 endometrial hyperplasias were found to have mutations in the p53 gene, whereas mutations were seen in three of 30 (10%) endometrial cancers (p < 0.02). The p53 mutations seen in three cancers were confirmed by direct sequencing (codons 157, 180, 272). CONCLUSION: Because it does not appear to be a feature of endometrial hyperplasias, mutation of the p53 gene may represent a relatively late event in endometrial carcinogenesis.

Deiodinases are highly active in intestinal tissue of developing rat fetuses and relatively inactive in adult intestinal cells, but little is known about these systems in the luminal contents of intestines. We have found both 5- and 5'-deiodinase activities in adult rat intestinal contents and have shown that their expression is inhibited by resident intestinal microflora, which are normally present in the adult but not in the fetus, possibly because they are bound by intestinal bacteria in the adult.

Method: Cognitive function was assessed with a neuropsychological test battery in consecutively admitted patients with schizophrenia (N=57), unipolar depression (N=29), and bipolar disorder (N=16). Results: The performance of the schizophrenic group was significantly below that of the groups with affective disorders on measures of attention and psychomotor speed, verbal and visual memory, and problem solving and abstraction. IQ was lower in the schizophrenic group and appeared to have deteriorated from a normal premorbid level that was not different from that of the affective disorder groups, as determined by the Wide Range Achievement Test-Revised reading test, a putative measure of premorbid intelligence. When IQ was controlled, differences between the groups in problem solving and visual memory remained. Psychiatric symptoms bad a larger impact on test performance in the affective disorder groups than in the schizophrenic group. Conclusions: These results suggest that patients with schizophrenia perform systematically worse on cognitive measures than patients with affective disorders, which is consistent with their generally poorer outcome. The results also indicate that schizophrenia and affective disorders are qualitatively distinguishable in neuropsychological terms, given differences in apparent intellectual deterioration, profiles of cognitive impairment, and associations between cognitive performance and psychopathology.

METHOD: Monolayer cultures of HMC were used to characterize binding and to measure cyclic (c)AMP, prostaglandin (PG)E2, and PGI2 production. Membrane preparations were used to assess ADP-ribosylation and for immunoblotting. RESULTS: HMC were found to specifically bind [I-125]IL-1 with an apparent K(d) of 2 x 10(-10))M. Incubation of HMC with IL-1 or TNF caused a time-dependent and dose-dependent accumulation of cAMP, as well as a significant potentiation of forskolin-promoted cAMP production. These cytokines also increase PGE2 and PGI2 output, independently of the activation of adenylyl cyclase. IL-1 treatment had no measurable effect either on cholera toxin-mediated and pertussis toxin-mediated ADP-ribosylation, or on the amount of G(i) proteins, as assessed by immunoblotting using a polyclonal antibody. CONCLUSIONS: It is suggested that IL-1 and TNF may activate one or more isoforms of the catalytic component of adenylyl cyclase, raising intracellular cAMP.

METHOD: Amniotic fluid was obtained by transabdominal amniocentesis from 146 consecutive patients admitted with the diagnosis of preterm labor and intact membranes. Fluid was cultured for aerobic and anaerobic bacteria as well as for mycoplasmas. Amniotic fluid IL-6 levels were measured using a monoclonal antibody-based enzyme-linked immunosorbent assay with a sensitivity of 0.03 ng/ml. Logistic regression and Cox's proportional hazards model were used to examine the effect of several variables on dichotomous outcomes or interval to delivery. RESULTS: Patients with a positive amniotic fluid culture had a significantly higher amniotic fluid IL,6 concentrations than patients with a negative culture (median 91.2 ng/ml, range 0.9 to 437 ng/ml versus median 0.4 ng/ml, range <0.3 to 195 ng/ml, respectively; P<.0001). An amniotic fluid IL-6 concentration of greater than or equal to 11.3 ng/ml had a sensitivity of 93.3% (14 of 15) and a specificity of 91.6% (120 of 131). All patients with an amniotic fluid IL-6 concentration above 11.3 ng/ml and a negative amniotic fluid culture (N = 11) delivered preterm and all placenta available for examination (N = 7) had histologic evidence of chorioamnionitis. Amniotic fluid concentrations of IL-6 were an independent predictor of preterm delivery, amniocentesis-to-delivery interval and neonatal morbidity and mortality. Moreover, IL-6 concentrations added significant information to the prediction of these outcomes to that provided only by clinical information such as cervical dilatation, gestational age at admission or at delivery. CONCLUSION: IL-6 is a sensitive and rapid test for the detection of microbial invasion of the amniotic cavity and for identifying women at risk for spontaneous preterm delivery and neonates at risk for morbidity and mortality.

METHOD: Amniotic fluid was retrieved by amniocentesis from 185 women classified into 11 groups according to gestational age (midtrimester, preterm gestation, and term), the presence or absence of labor, spontaneous rupture of membranes and microbial invasion of the amniotic cavity. sTNF-r I was assayed with a sensitive and enzyme-linked immunosorbent assay (ELISA) validated for amniotic fluid. In addition, sTNF-r I concentrations were determined in fetal blood obtained by cordocentesis in preterm gestations (N = 24) or at the time of delivery after spontaneous labor at term (N = 10). sTNF-r I concentrations were also measured in maternal venous and cord blood and neonatal urine (n = 13). RESULTS: sTNF-r I was found to be present in all amniotic fluid samples, maternal blood and fetal blood and neonatal urine samples; sTNF-r I concentrations were higher in the midtrimester than at term (mean +/- SD: 36.2 +/- 12.2 ng/ml versus mean +/- SD: 5.56 +/- 5.72 ng/ml [P < .05]); patients with preterm labor and microbial invasion of the amniotic cavity (with intact or with ruptured membranes) had significantly higher amniotic fluid concentrations of sTNF-r I than patients without microbial invasion; in the absence of microbial invasion, parturition (both term and preterm) was not associated with changes in amniotic fluid concentrations of sTNF-r I; neonatal urine contained the highest concentrations of sTNF-r I of all biological fluids assayed including maternal and neonatal/fetal blood and amniotic fluid., CONCLUSIONS: It was concluded that sTNF-r I is a physiologic constitutent of amniotic fluid, as well as of the fetal and maternal plasma; that amniotic fluid sTNF-r I concentrations decrease as a function of gestional age and increases in the concentration of the sTNF-r I are part of the host response to intrauterine infection in preterm parturition.

One novel approach to cancer treatment involves targeting a cytotoxic agent to a cancer cell. Immunotoxins have been developed that contain a potent toxin (either Pseudomonas exotoxin, ricin toxin, or diphtheria toxin) coupled to a targeting moiety that directs the molecule to cells expressing a certain antigen. Chemically coupled immunotoxins have been developed over the past 12 years. These bind to and kill cells expressing many tumor-associated antigens. Initial clinical results were disappointing, but recent results have been more promising. Furthermore, newer immunotoxins have been developed that will soon be in clinical trials. Some of these are recombinant toxins that have been developed using techniques of genetic engineering. Transforming growth factor-alpha, acidic fibroblast growth factor, insulin-like growth factor-1, interleukin-2, interleukin-4, interleukin-6, the binding portions of monoclonal antibodies, and CD4 have been used to direct toxins to cancer cells or cells infected with the human immunodeficiency virus type 1. Efforts are under way to circumvent problems such as immunogenicity that may limit the clinical usefulness of immunotoxins.

The tumor weighed 199 g and consisted of areas typical of adrenal carcinoma and areas of sarcoma. The sarcomatous component of the tumor showed osteogenic and chondroid differentiation. Vimentin stained both the carcinomatous and sarcomatous regions. Four months after resection, the patient developed metastases. This is the third reported case of adrenal carcinosarcoma and the only case in which hyperaldosteronism or bony differentiation was observed. C1 NCI,DIV CANC TREATMENT,SURG BRANCH,BETHESDA,MD 20892.

The reactivity of the antibodies, restricted to human squamous epithelium, was unique, differing from that of all known forms of pemphigus. This also was confirmed by immunoprecipitation. The problem is that these circulating antibodies could be missed if not determined on human substrate. It is to be established whether such cases present a new type of pemphigus or a unknown dermatosis with an autoimmune response of a pemphigus type.

A complete enzyme analysis (21 enzymes) revealed that there was enzyme polymorphism among the isolates of each species group. Any one Desert Storm L. major isolate could differ from any other for 1-3 enzymes, and any L. tropica isolate could differ from any one other for up to eight enzymes. Enzyme polymorphism data from other L. major and L. tropica isolates from Africa and the Middle East region were obtained and combined with the Desert Storm data to produce population enzyme polymorphism estimates. Results from these population data indicated that L. major parasites could be expected to differ from each other for as many as eight enzymes and still be L. major and similarly, L. tropica isolates could differ for as many as 14 enzymes. These expected isolate variation extremes have not been observed among the isolates studied. All L. major and most L. tropica isolates were from patients who, as expected, presented with cutaneous disease, but the Desert Storm and two Kenyan patients infected with L. tropica presented with a viscerotropic disease, the symptoms of which are unlike those of classic visceral leishmaniasis. Such unrecognized presentation for these L. tropica-infected patients indicates that both parasite and patient can play critical roles in disease manifestations. The Desert Storm isolates are, as indicated, either L. major or L. tropica. C1 WALTER REED ARMY INST RES,DIV EXPTL THERAPEUT,WASHINGTON,DC 20307. NIAID,PARASIT DIS LAB,BETHESDA,MD 20892.

The two-phase solvent systems used for the separation were composed of n-heptane containing bis(2-ethylhexyl) phosphoric acid (stationary phase) and diluted citric acid (mobile phase), where the distribution ratios of the elements can be optimized by selecting a proper acid concentration. The mobile phase was eluted through the column at a flow rate of 5.0 mL/min while the apparatus was rotated at 800 rpm. Continuous detection of the metal elements was effected by measurement of the emission intensity with direct current plasma atomic emission spectrometry (DCP-AES), where the elution curve was obtained by on-line monitoring of each emission signal. Each metal element was well resolved at high partition efficiencies ranging from 200 to 3600 theoretical plates. C1 SHIMADZU CO LTD,ANALYT INSTRUMENTS RES LAB,NAKAGYO KU,KYOTO 604,JAPAN.
