近年来由于单克隆抗体技术、免疫电镜、遗传工程以及分子杂交技术的进展,推动了病毒性肝炎研究的深入,仅就近二年研究的主要进展综述如下。 一、甲型肝炎 病毒分离的研究,继上海用人胚肺二倍体细胞株(SL_7)分离甲肝病毒(HAV)成功后,应用Alexander细胞株,Vero细胞株、人胚肾细胞均先后分离病毒 In recent years, due to the progress of monoclonal antibody technology, immunoelectron microscopy, genetic engineering and molecular hybridization technology, the research on viral hepatitis has been advanced. Only the major advances in recent two years are summarized as follows. First, the separation of hepatitis A virus, following the Shanghai human embryonic lung diploid cell line (SL_7) isolated Hepatitis A virus (HAV) success, the application of Alexander cell lines, Vero cell lines, human embryonic kidney cells were isolated virus
