[The characteristics of the lipid peroxidation status and the activity of the main antioxidative enzymes in patients with duodenal peptic ulcer who took part in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station].

Results are submitted of investigations designed to study processes of lipid peroxidation and activity of chief antioxidant enzymes in those patients with duodenal ulcer who took part in the elimination of the effects of the Chernobyl accident. The above contingent of examinees displayed activation of lipid peroxidation (accumulation of conjugated dienes, keto-dienes, malonic dialdehyde) and decline in the activity of superoxide-dismutase, catalase. The results obtained attest to the need for using antioxidants in a complex therapy of patients with peptic ulcer, who have come to be exposed to ionizing radiation.
