[Viral hepatitis and normal killers].

The results of the study of functional activity of normal killers in different liver diseases: acute virus hepatitis A (26 patients), acute virus hepatitis B (24 patients including 3 with hepatic coma), and 12 patients with chronic liver diseases including 8 with chronic persisting hepatitis and 4 with chronic active hepatitis are presented. A control group included 17 apparently normal subjects. The most marked decrease of the level of activity of normal killers was found in hepatic coma and in chronic active hepatitis. The expedience of determinations of the activity level of normal killers for prognosis of immediate and remote outcomes of viral hepatitides as well as for the development of new methods of immunocorrecting therapy is discussed.
