[Characteristics of lipid peroxidation in alcoholic intoxication]. / Ob osobennostiakh perekisnogo okisleniia lipidov pri alkogol'noi intoksikatsii.

ABSTRACT

Content of malonic dialdehyde and dynamics of its accumulation in ascorbate-dependent lipid peroxidation (LP), content of diene conjugates, lipid hydroperoxides and lipofuscin-like pigments as well as activity of antioxidant enzymes (superoxide dismutase, glutathione peroxidase and glutathione transferase) were studied in homogenates of liver, lung, heart and kidney tissues of persons suffering from chronic alcoholism during life-time, of persons lost from acute alcohol intoxication as well as of persons not abusing with alcohol during life-time and lost from accidents (control). In chronic alcoholism the rate of ascorbate-dependent LP was distinctly increased in liver tissue as compared with controls or with acute mortal alcohol intoxication, while the rate of the patterns studied was increased in lung tissue of the latter group of patients. At the same time, increase in content of lipofuscin-like pigments and a decrease in the activity of antioxidant enzymes studied were noted.
