[Autoimmune hepatitis (history of the research, current aspects)]

Important achievement in the study of autoimmune hepatitis are shown, particularly in establishing the role of hepatitis viruses, other hepatotropic viruses and some medicines.

It is thought valid that investigation of autoimmune reactions produced by hepatitis viruses and other agents will enable a revision of classification of chronic hepatitis.
