Antioxidant status of skin and wound tissue of aged rats (a) superoxide dismutase (SOD), unit represents the amount of enzyme that inhibited the rate of reaction by 50%; catalase (CAT), unit represents 100 nmol H₂O₂ utilized/min; and glutathione peroxidase (GPx), unit represents 10 nmol NADPH oxidized/min (b) Vitamin E and ascorbic acid (AA) content (c) GSH (μg/mg protein) and thiobarbituric acid reactive substances (TBARS, nmol/mg protein) in skin and wound tissue of aged rats as compared to control rat. Values are represented as mean ± SE (n = 6), *P ≤ 0.05.
