title: [Status of the processes of free-radical oxidation and the antioxidation system in patients with a severe course of hepatitis B].
abstract: Sixty patients with severe forms of acute viral hepatitis B (AVHB) without symptoms of acute hepatic encephalopathy (AHE) and 20 AVHB patients with such symptoms were examined for red blood cell and serum levels of dienic conjugates (DC), malonic dialdehyde (MDA), reduced glutathione (RG), activity of superoxydismutase (SOD), catalase, glutathione peroxidase-1 (GP1), glutathione peroxidase-2 (GP2), glutathione reductase (GR), glutathione transferase (GT). Elevated MDA and DC concentrations were found in grave AVHB, in coma and precoma DC reduced. MDA levels in precoma fell, in coma rose. The activity of SOD, GP1, GP2, GR and RG concentration were low, especially in AHE symptoms. GT and catalase activity proved high in severe AVHB with a trend to lowering in precoma and coma.
