ABSTRACT
The back of rats was immersed in 95℃ water for 10 seconds to produce 10% and 30% TBSA full thickness burn injury. Malondialdehyde (MDA) level in plasma, erythrocytes, the liver and the lungs, the activity of superoxide dismutase (SOD), glutathione peroxidase (GSSG-Px), and catalase (CAT) in the blood, liver and lungs, and the activity of liver xanthine oxidase (XO) were determined 4 hours postburn. It was found that MDA level and SOD activity in rat tissues, XO and CAT activity in the liver, and GSSG-Px activity in the lungs and blood increased significantly aftfe injury. The severity of these changes positively correlated with the area of scalding except the SOD activity in the liver and lungs which showed no significant difference in those animals with 10% and 30% TBSA scalding. However the CAT activity in the blood and lungs decreased postburn and the liver GSSG-Px activity in 10% and 30%TBSA scalding-injured rats was higher and lower than that of the control respectively.The results imply that when scalding involves less area of body surface, the function of anti-peroxidation system of the body will be enhanced by inducing the synthesis of antioxidases; when severe scalding covers larger body surface, the induction of enzyme synthesis will be deficient in some tissues of the body.
