The total proteolytic activity in blood and tissues and peroxide resistance of erythrocytes were studied in animals at different stages of burn disease. Carbaton, an antioxidant of a pyridine series, is analyzed for its effect on these indices. Considerable activation of proteolysis in tissues and a decrease of the erythrocyte resistance at burn shock and septicotoxemia stages are established. Carbaton being applied as a drug, influences positively the studied processes; a degree of the shift correction depends on the preparation dose.
