HBsAg, HBcAb and HBsAb were examined with radio-immunoassay in 265 patients with glomerular disease, who were admitted to wards or visited to outpatient clinics of department of pediatrics, Seoul National University Hospital, from Jan., 78 to Oct. 80, and in 576 control group, with other than liver disease and without history of transfusion. The incidence in glomerular disease was 10.2%(27 of 265 patients)-nephrotic syndrome 9.2%(12 of 130); acute glomerulonephritis 7.3%(5 of 68), recurrent hematuria 7.7%(2 of 26), H-S nephritis 25%(3 of 12), chronic renal failure 21%(3 of 14), and the others 13.3%(2 of 15), while the incidence of HBs antigenemia in control group was 5.03%(29 of 576 patients)-male 5.5%(21 of 362), female 4.2%(8 of 214). The overall incidence of HBs antigenemia in renal disease was statistically higher than that of control group(p<0.05), though the respective incidences of the above each renal disease group were somewhat higher than that of control group, however they were not statistically significant, The incidence of positive rate of HBsAb and/or HBcAb in control group was 26.7%(56 of 209), and that in renal disease was 23%(18 of 578).

BACKGROUND: It has been shown that cerebral ischemia alters brain acetylcholine (Ach) metabolism. In an attempt to elucidate the mechanisms for ischemia-induced release of Ach in vitro, the effects of drugs which can influence the cholinergic neurotransmission on the ischemia-induced release of [3H]Ach from cerebral cortical slices of the rat were examined. METHODS: The cortices of decapitated rats were chopped and dispersed in artificial CSF. Then, the tissue suspensions were incubated with [3H]choline. The tissues were transferred and incubated in washing, hypoglycemic (deprivation of glucose), ischemic (deprivation of oxygen and glucose) and extracting plates sequently. Ischemia-induced release of [3H]Ach was expressed as percentage of the total [3H]Ach present in the slices. RESULTS: Ischemia induced significant release (about 9.3% of total tissue content) of [3H]Ach from cerebral cortical slices in vitro. This [3H]Ach release was significantly attenuated by tetrodotoxin, a voltage-sensitive Na+-channel blocker, and Mg2+, a physiological N-methyl-D-aspartate (NMDA) receptor blocker. Vesamicol (1 M), a blocker of vesicular transport of Ach, MK-801 and ketamine, NMDA receptor antagonists, 6,7-nitroquinoxaline-2,3-dione (DNQX) and 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX), kainate/AMPA receptor antagonists, and 6-nitro-7-sulphamoylbenzo[f]quinoxaline-2,3-dione (NBQX), a AMPA receptor blocker attenuated the [3H]Ach. Nitrendipine, nimodipine, inhibitor of L-type Ca2+ channels, and -conotoxin GVIA, an inhibitor of N-type Ca2+ channels, significantly attenuated the ischemia-induced release of [3H]Ach. Omission of Ca2+ from incubation media attenuated the ischemia-induced [3H]Ach release. Inhibitors of intracellular Ca2+ release, dantrolene and TMB-8, and a cell-permeable calcium chelator, 1,2-bis (2-aminophenoxy)-ethane-N, N, N+, N+-tetraacetic acid tetrakis (acetoxymethyl) ester (BAPTA-AM), inhibited the ischemia-evoked [3H]Ach release. CONCLUSION: These results suggest that the ischemia can induce Ach rele.
