本文研究目的在于通过测定供血者中B型肝炎抗原(HBAg)(即肝炎相关抗原,或HAA——译者注),估计其受血者黄疸型和无黄疸型肝炎的发病率,并确定输入经对流免疫电泳法(CIE)测定HBAg阴性而能用更敏感的放射免疫法(RIA)测出含有低浓度HBAg的供血者血液是否会引起B型病毒性肝炎。材料和方法:全部受血者均于输血前采血,输血后每2周采血一次,连续三个月;继之每月一次,总共6个月。每份标本均测定HBAg和谷草转氨酶(SGOT)值。若受血者出现肝炎的症状或体征,或SGOT>60单位(正常最高值33)时,则重新住院详细检查。每一供血单位的血浆标本均在-10℃保存。
The purpose of this study was to estimate the incidence of jaundice and jaundice hepatitis in recipients by measuring the level of hepatitis B antigen (HBAg) in donors (ie hepatitis related antigen, or HAA) HBAg was negative by convective immuno-electrophoresis (CIE) and more sensitive radioimmunoassay (RIA) was used to determine whether blood from donors with low concentrations of HBAg would cause type B viral hepatitis. MATERIALS AND METHODS All blood recipients took blood prior to blood transfusion. Blood was taken every 2 weeks for three months consecutively, followed by monthly for a total of 6 months. HBAg and aspartate aminotransferase (SGOT) values were determined for each specimen. If the recipient presents with symptoms or signs of hepatitis, or SGOT> 60 units (normal maximum 33), then re-hospitalized detailed examination. Plasma samples from each donor are stored at -10 ° C.
