19. Radioresistance of Mongolian Gerbils

Author

Jacobson, A. P., Sullivan, M. T., Lutkenhoff, D. W., Parkinson, W. C., and Overway, D. J.

Abstract

Seventy-six 8 week old Mongolian gerbils were exposed to acute, whole-body fast neutrons produced by The University of Michigan 83-in. cyclotron. Groups of seven or eight gerbils were given doses between 485 and 881 rad at 25 rad per minute. The LD50/30 determined by probit analysis was 750 rad, with 95 per cent fiducial limits of 733 and 776. For the 50 per cent mortality level, an r.b.e. of fast neutrons compared with cobalt-60 of 1·45 was determined. For the same end-point, the r.b.e. for fast neutrons compared with X-rays is 1·33. Mortality data, body-weight and microhaematocrit changes are discussed.

Abstract

Functional communication training (FCT) is a frequently used treatment for reducing problem behavior exhibited by individuals with developmental disabilities. Once the operant function of problem behavior is identified by a functional analysis, the client is taught to emit an appropriate communicative response to obtain the reinforcer that is responsible for behavioral maintenance. Studies on FCT have typically used small numbers of participants, have reported primarily on clients for whom FCT was successful, and have varied with respect to their use of other treatment components. The main purposes of the present study were to evaluate the efficacy of FCT for treating severe problem behavior in a relatively large sample of individuals with mental retardation (N = 21) and to determine the contribution of extinction and punishment components to FCT treatment packages. FCT with extinction was effective in reducing problem behavior for the majority of clients and resulted in at least a 90% reduction in problem behavior in nearly half the applications. However, when demand or delay-to-reinforcement fading was added to FCT with extinction, treatment efficacy was reduced in about one half of the applications. FCT with punishment (both with and without fading) resulted in at least a 90% reduction in problem behavior for every case in which it was applied.

Abstract

Background & Aims: Lamivudine inhibits hepatitis B virus replication. This study investigated 6 months of lamivudine treatment at three doses., Methods: Fifty-one patients (43% white, 49% Asian) with chronic hepatitis B were randomly assigned to receive 25, 100, or 300 mg of lamivudine orally once daily for 24 weeks with 24 weeks' follow-up., Results: Serum hepatitis B DNA by liquid hybridization decreased in all patients and was undetectable at the end of the treatment in 7 of 12 (58%, 25 mg), 13 of 14 (93%, 100 mg), and 14 of 16 (88%, 300 mg) patients. Of the 36 patients with abnormal alanine aminotransferase (ALT) levels at baseline, 7 of 11 (64%, 25 mg), 5 of 11 (45%, 100 mg), and 5 of 14 (36%, 300 mg) normalized ALT at treatment completion. Quantitative decreases hepatitis Be antigen and hepatitis B surface antigen concentrations were observed at all doses. In most patients, markers of replication returned after treatment. Two patients (4%) were anti-HBe positive at the end of follow-up. Lamivudine was well tolerated. The incidence of adverse events was similar across all dose groups. However, 2 patients developed temporary hepatic decompensation after increase in transaminase levels after treatment., Conclusions: Lamivudine was well tolerated and induced sustained suppression of hepatitis B replication during treatment in all patients at all doses. These data support investigation of longer treatment durations of 100 mg once daily.

Abstract

Three population groups, 1500 blood donors, 513 antenatal women representing a normal population group and 250 sicklers representing a multiply transfused group were studied to determine the prevalence of hepatitis C viral (HCV) infection in Jamaica. The relationship to liver enzyme levels, hepatitis B infection, syphilis and HIV infection was also investigated. Sera were screened by enzyme-linked immunoassay (EIA) for anti-HCV C100-3 and subsequently tested by a supplementary second generation recombinant immunoblot assay (RIBA). In the blood donors, the prevalence of anti-HCV was low, 0.3%-0.4%, the same level as that reported by several European countries. In the multiply transfused sicklers, the prevalence was more than seven times higher. No HCV infection was detected in the antenatal group. There was little correlation between HCV infection and surrogate markers alanine aminotransferase (ALT) and antibody to hepatitis B core antigen (anti-HBc) and no correlation with sexually transmitted diseases.

Abstract

This article reviews the history, classification, and disease associations of the known human retroviruses and outlines their profound effects on the practice of transfusion medicine. The immunodeficiency viruses, HIV-1 and HIV-2, produce a cytolytic effect on infected lymphocytes, and are the causative agents of AIDS. In contrast are the oncoviruses, including HTLV-I and HTLV-II, which are typically lymphoproliferative and able to induce cellular transformation. Human foamy viruses, more recently recognized as a potential human neuropathogen, resemble the other retroviruses with their complex genome organization and structure.

Abstract

Measurement of glycosyltransferase activity in whole cell extracts is often complicated by the fact that several enzymes in an homogenate are capable of using the same nucleotide sugar donor, thereby generating a range of products from both an exogenous and any endogenous acceptors. We report the use of a novel combination of techniques to simultaneously identify and quantify the products generated from a whole cell extract in a single experiment. Several radiolabeled glycosphingolipid products were generated by the addition of UDP-[14C]Gal to a reaction mixture containing an homogenate from a human leukemia cell line, THP-1. After the 14C-labeled products were separated on a TLC plate, storage phosphor technology and immunostaining (with carbohydrate sequence-specific monoclonal antibodies) were used sequentially on the same plate to simultaneously identify and quantify each of the glycosyltransferase products. This method allows product identification and quantification in the femtomole range. Thus, low levels of endogenous acceptors were easily detected. We have used a similar method with UDP-[3H]Gal to obtain glycosyltransferase product profiles from several human leukemia/lymphoma cell lines and subsequently identify two galactosyltransferase activities in these cell lines: UDP-Gal:Gal beta 1-4Glc beta 1-1Cer alpha 1,4galactosyltransferase; and UDP-Gal:GlcNAc beta 1--3Gal beta 1--4Glc beta 1--1Cer beta 1,4galactosyltransferase. In addition to product characterization, this method was used with reaction mixtures at different pH to demonstrate the usefulness of the method for characterizing multiple enzyme activities simultaneously.

Abstract

Interviews and laboratory testing were conducted for 168 contacts referred by former blood donors identified as seropositive for antibody to human T-lymphotropic virus type I (HTLV-I) or type II (HTLV-II). Thirty-two (28%) of 114 heterosexual contacts of seropositive donors, including 12 women and 20 men, were found to be antibody positive. None of 40 offspring (except one adult man who reported sexual contact in Puerto Rico) or 14 other (nonspousal) family members were seropositive. Thirty-one of the seropositive contacts were typeable as having either HTLV-I (52%) or HTLV-II (48%). Assessment of couples found that the median duration of the sexual relationship was significantly longer (p = 0.03) for those in which both partners were infected than in discordant pairs. Analysis of risk history data for 22 infected couples revealed that, in three cases, risk factors (Japanese ancestry or sexual contact with an injecting drug user) could be identified in the women, but not in their male partners. Among couples in which the male had the greater risk history, the risk factor was either a history of transfusion, birth or sexual exposure in an endemic area, or injected drug use. Counseling strategies for individuals with HTLV-I or HTLV-II infection should take into account the relatively high seroprevalence in their partners and should address the potential for sexual transmission in both directions.

Abstract

The relative mobilities of various N-linked oligosaccharides reductively aminated to the charged fluorophore 8-amino-naphthalene-1,3,6-trisulphonic acid (ANTS) were determined by electrophoresis on high-density polyacrylamide slab gels. Each ANTS-derivatized oligosaccharide was assigned a relative migration index (RMI) expressed in terms of glucose equivalents, which was conveniently estimated by reference to a homologous series of ANTS--maltooligosaccharides run on each gel as oligosaccharide size standards. High-mannose-, complex- and hybrid-type structures were generally well resolved and easily visualized at picomole levels by simple UV light excitation. Application of these methods for the qualitative analysis of the oligosaccharides released from bovine fetuin and bovine asialofetuin by peptide-N-glycosidase F illustrates the usefulness of these techniques as fast, simple, and inexpensive tools for the characterization of N-linked oligosaccharides attached to glycoproteins.
