对肝炎免疫学的研究,是解决肝炎发病规律的重要方面。近年来对肝炎免疫学研究,取得了一定的进展。急性肝炎的免疫学乙型肝炎抗原(HBAg)与抗HBAg抗体:在急性肝炎中,有部分患者血清中带有HBAg。这一部分患者已证明是属于乙型病毒性肝炎(旧名血清肝炎)。当人体感染乙型肝炎后29～43天,血清中就开始发现HBAg,再过2周～2月后血清谷草转氨酶才升高,而临床症状则到感染后65天(经注射途径感染者)或98天(经口感染者)才出现。至于抗HBAg抗体的检查,早期由于检查方法不够敏感,因而阳性率不高。自从应用放射免疫测定方法之后,抗HBAg抗体的检出率大为提高。Lander
The study of hepatitis immunology is an important aspect to solve the regularity of hepatitis incidence. In recent years, hepatitis immunology research has made some progress. Immunology of acute hepatitis Hepatitis B antigen (HBAg) and anti-HBAg antibodies: In acute hepatitis, some patients have serum HBAg. This part of the patient has proved to belong to hepatitis B (old name hepatitis). When the body infected with hepatitis B after 29 to 43 days, the serum began to find HBAg, and after 2 weeks to 2 months after the serum aspartate aminotransferase was elevated, while the clinical symptoms to 65 days after infection (infected by the injection route) Or 98 days (oral infection) appeared. As for the examination of anti-HBAg antibody, the early detection method is not sensitive enough, so the positive rate is not high. Since the application of radioimmunoassay methods, the detection rate of anti-HBAg antibodies has greatly increased. Lander
