[Malondialdehyde concentration in blood plasma of patients with liver diseases].

Malondialdehyde (MDA) level was determined spectrophotometrically with thiobarbituric acid method on 50 healthy persons and 160 patients with alcoholic and nonalcoholic liver diseases. Alcoholics without liver damage show normal plasma MDA values. Alcoholic fatty liver, alcoholic hepatitis and alcoholic liver cirrhosis cause an increase of MDA values. The highest concentrations of MDA were found on patients with acute virus hepatitis. Also noninfectional hepatitis and nonalcoholic liver cirrhosis showed an elevated MDA-Level. Liver damage and lipid peroxidation are considered as closely connected processes.
