研究HBsAg阳性者持续携带时间长短及其转归、预后如何,可以为进一步研究和制订乙型肝炎的防治措施提供科学依据。1979年对我市某单位855人进行了调查,HBsAg阳性率15.3％,1979～1985年又对其中资料完整的HBsAg阳性者48例作了追踪观察,应用敏感的方法检测,现将结果报告如下。材料、方法与结果 1979年6月对某单位855人抽静脉血用RPHA法及PHA法检测HBsAg、抗-HBs. 1980年10月、1983年8月和1985年6月分别对其中的HBsAg阳性者48例及阴性者14例用相同方法进行复检,1983及1985年加用固相放射免疫(RIA)夹心
Studying the duration of HBsAg positive patients and their prognosis, how the prognosis, can provide scientific basis for further research and development of prevention and treatment measures of hepatitis B. In 1979 a survey of 855 people in a unit of our city, HBsAg positive rate of 15.3%, again from 1979 to 1985, one of 48 cases of HBsAg-positive patients were followed up, the application of sensitive methods to detect the results are reported as follows . Materials, Methods and Results HBsAg and anti-HBs were detected by RPHA and PHA in 855 people in a unit in June 1979. HBsAg and anti-HBs were detected in October 1980, August 1983 and June 1985, respectively 48 cases and negative in 14 cases using the same method for re-examination, 1983 and 1985 plus solid-phase radioimmunoassay (RIA) sandwich
