Gastric juice, saliva, and fluid adherent to the endoscope were collected from 50 patients who were seropositive for hepatitis B surface antigen (HBsAg) during the endoscopic examination of the upper gastrointestinal tract, and examined for HBsAg, using the radioimmunoassay. A positive test was obtained from 42.0% of the saliva samples, in 32.0% of the gastric juice specimens, and in 31.3% of the fluid adherent to the scope. These results should be taken as a warning, that calls for a more careful screening of the patients and disinfection of the endoscope.
在对50例乙肝表面抗原（HBsAg）血清学阳性患者进行上消化道内镜检查时，收集了他们的胃液、唾液及内镜附着物，并采用放射免疫分析法检测其中的HBsAg。结果显示，42.0%的唾液样本、32.0%的胃液样本及31.3%的内镜附着物检测呈阳性。这些结果应引起警示，需对患者进行更仔细的筛查并加强内镜消毒。
