| Abstract: | Cryostat sections of the liver representing fulminant B-viral hepatitis were investigated with antisera against human immunoglobulin G(IgG), immunoglobulin M(IgM), C3, C4, C1q, hepatitis B surface antigen (HBsAg), and T-lymphocytes using the immunofluorescence and immunoperoxidase techniques. The liver showed positive staining for IgG, IgM, C3, C4, C1q, and HBsAg in the viable and necrotic hepatocytes and Kupffer cells in a granular fashion. Furthermore, the cell membrane of lymphocytes present in the liver were positively stained with anti T-lymphocyte sera. The numbers of T-lymphocytes recognized were predominant both in portal tracts and within hepatic lobules over those of non-T-lymphocytes. It suggests that perhaps some of the end results of fulminant hepatitis inflammatory reactions may be mediated in part by T-lymphocytes. |
