[Free-radical lipid peroxidation in patients with acute gastro-intestinal hemorrhage]

Free-radical lipid oxidation (FRLO), antioxidant system and rheological blood properties were studied in 63 patients with ulcer disease, of them, in 39--complicated by acute bleeding. Twenty healthy subjects served as a control. It was established, that hemorrhage led to considerable FRLO activation. The correlation between the increase in the content of the FRLO products in the erythrocytes and their functional properties was revealed.
