近年来,随着免疫学及免疫组织化学技术的发展,组织内乙型肝炎抗原(HBAg),特别是乙型肝炎表面抗原(HBsAg)的定位技术,在国内外已得到广泛应用。组织内HBsAg的显示方法有免疫荧光、免疫酶标和地衣红染色法,常规H.E.染色中肝细胞的毛玻璃样变也被视作为HBgAg的形态学指标。本文选取60例各种肝病的肝组 In recent years, with the development of immunological and immunohistochemical techniques, the localization technique of hepatitis B antigen (HBAg), especially hepatitis B surface antigen (HBsAg), has been widely used at home and abroad. Immunohistochemistry, immunohistochemistry, and lichen staining are the methods used to display HBsAg in the tissues. Hepatoblastoid changes of hepatocytes in conventional H.E. staining are also considered as morphological markers of HBgAg. This article selects 60 cases of hepatic disease liver group
