Abstract
Alterations in lipid content and composition in the N-nitrosodiethylamine-induced hepatocarcinoma were investigated. Rats were administered with N-nitrosodiethylamine in the drinking water for 12 weeks followed by normal tap water for another 6 weeks. The cholesterol content in the liver was increased shortly after the administration of N-nitrosodiethylamine and remained elevated after the removal of the nitrosoamine from the water. The phosphatidylethanolamine level was elevated during N-nitrosodiethylamine administration with a concomitant reduction in phosphatidylcholine level. Lysophosphatidylcholine and sphingomyelin levels were increased during the last four weeks of the study. The level of phosphatidylinositol was substantially reduced after eight weeks of N-nitrosodiethylamine treatment, and remained low during the post-treatment period. We postulate that changes in lysophosphatidylcholine and sphingomyelin may be a compensatory mechanism for maintaining the asymmetrical distribution of choline-containing lipids in the outer leaflet of the membrane. The elevated level of cholesterol may be a useful indicator for the early detection of N-nitrosodiethylamine-induced hepatocarcinoma.

Abstract
Doppler ultrasound was adopted in a study of fetal umbilical artery flow velocity waveforms in 81 cases of late pregnancies (28-41 gestational weeks). The peak systolic/end-diastolic ratio (A/B) and the Pourlot index were used as indices for assessing placental resistance. Both the A/B ratio (2.34 +/- 0.44) and Pourlot index (0.56 +/- 0.07) decreased while the gestational week was increasing, and they had a good correlation with the gestational week (r1 = -0.90, r2 = -0.93). The results indicated that the placental resistance became lower when the gestational week was increasing. This method has been documented a useful noninvasive technique for the exam of placental resistance.

Abstract
The auditory brainstem responses (ABR) were recorded from 20 adults aged 16 to 43 year with normal hearing using a paired click stimuli with interaural time differences (delta T = 0-3 ms). The Binaural Interaction (BI) was studied by computer to obtain a curve of derived ABR. The results showed that there was a different waveform at the region of wave V. It seems to have arose from the region of midbrain when delta T = 0-2 ms and showed a good stability.

Abstract
In order to elucidate the role of anti-thyroglobulin (Tg) autoantibodies (A-Ab) in experimental autoimmune thyroiditis (EAT), a kinetic study was conducted in EAT-susceptible (CBA/J) and non-susceptible (C57BL/6) strains of mice. From day 0 to 70 post-Tg immunization, titers of A-Ab to Tg and to the linear 5-10-kDa Tg tryptic fragment inducing EAT as well as anti-idiotypic A-Ab representing the internal image of the thyroidogeneic antigen were measured. EAT onset, development and recovery correlate with the presence of two subsets of A-Ab only in susceptible strains of mice. First, with the presence of anti-Tg A-Ab to one determinant borne by the linear 5-10-kDa Tg tryptic fragment, and second with the presence of anti-idiotypic A-Ab specific for the monoclonal anti-Tg A-Ab (3B8G9) paratope which binds to Tg determinant inducing EAT.

Abstract
Using the reagent kits for detecting human HBV, primary serologic investigation was made in 6 kinds of domestic animals and fowls (total 673) by ELISA, spot hybridization and immuno-electronmicroscopy. The results showed that some sera samples of pigs, rabbits, chicken and geese were HBsAg, HBeAg positive and positive for spot hybridization by using 3(2)P-HBV-DNA probe, which suggested that HBV-like viruses might exist in those domestic animals and fowls. HBV-like virus particles were seen in one pig serum sample which was HBsAg positive. The particles could be divided into three forms in shape, large spherical particle (40-55nm), small spherical particle (20-30nm) and short filament particle. The further studies are needed.

Abstract
Eighteen patients with leukemia have received HLA-identical allogeneic bone marrow transplantation (BMT) at our hospital since 1981. Fifteen of these patients have been living without relapse. for prophylaxis of GVHD, MTX was used in 8 patients, and cyclosporine (CSP) together with MTX in 6 patients, 3 received multiple agents at much smaller dosage, including monoclonal antibody. All patients received intravenous placental gamma-globulin, and 16 received garlic extract. Three patients died. One, who neither received MTX, nor CSP died of hyperacute GVHD, one who did not receive garlic extract died of GMV pneumonia, and the third one died of tuberculosis 18 months after BMT.

Abstract
Abstract
1. There exists a linear correlation between rheological parameters (crossover frequency and crossover modulus) and structural parameters (Mw, and MWD) for commercial-type butyl elastomers. 2. There appears to be potential value in utilizing rheological testing for quality control for commercial-type butyl elastomers. 3. Further work is required to resolve testing problems (air entrapment and sample trimming) which affect the precision of the rheological measurements.

Abstract
Serological mass surveys were carried out in Zangwu County, China, using an immunoenzymatic test. 3,533 persons were found to have Epstein-Barr virus (EBV) IgA/VCA antibody among 148,029 persons age 30 years and older who were tested during 1978-1980. Among the IgA/VCA antibody-positive persons, 55 nasopharyngeal carcinoma (NPC) cases were detected. Follow-up studies were carried out yearly on the IgA/VCA antibody-positive persons for 1-3 years, and 32 additional NPC patients were diagnosed. IgA/VCA antibody was detected 8-30 months (average, 13 months) prior to the clinical diagnosis of stage I NPC. There was no marked difference in geometric mean titers of IgA/VCA antibody between the period before onset of NPC and after diagnosis at stage I, but antibody titers were higher during stages II-IV. The NPC detection rates for all persons tested serologically and for IgA/VCA antibody-positive persons, respectively, was 2- and 82-fold the annual incidence of NPC in the general population of the same age group. These data further indicate that serological testing is valuable for the diagnosis of NPC, especially in its early stages, and that EBV may play an important role in the development of NPC.
