    With an immunofluorescence technique using rabbit hepatocytes isolated by a non-enzymatic method an autoantibody directed against liver-cell-membrance was identified. Sera from 361 patients with various liver diseases and 274 patients with primary non-hepatic diseases-many associated with non-organ-specific auto-antibodies-were examined. The antibody (LMA) was found in 27 out of 72 patients with hepatitis-B-surgace antigen (HBsAg)-negative chronic active hepatitis and in 17 out of 28 patients with HBsAg-negative non-alcoholic cirrhosis. Only two patients had LMA and HBsAg, and both had chronic active hepatitis. One patient with extrhepatic disease was found to have LMA, and this patient had biochemical evidence of liver disease. Hence there is a close correlation between the presence of LMA and HBsAg-negative chronic inflammatory liver diseases and its detection may help in diagnosis.
