[Direct and induced lymphocytotoxicity to rabbit hepatocytes in chronic active hepatitis].

The lymphocytotoxicity to rabbit hepatocytes either direct or serum induced was evaluated in chronic active hepatitis (CAH). We obtained the following results: a) the direct lymphocytotoxicity obtained in CAH patients significantly correlated with the cytotoxicity induced by CAH sera in normal lymphocytes; b) no difference could be recorded in CAH HBsAG positive or negative; c) the target antigen of the immune reaction seems to be the liver specific lipoprotein.
