Lipid peroxidative activity in hepatic homogenate and microsomal fraction in Sh (black bars) and PH (gray bars) with and without vitamin-treatment. Control: Group of animals without treatment; vitamin E: E1 (30 mg/kg body weight), E2 (600 mg/kg body weight); and vitamin C: C1 (30 mg/kg body weight), C2(100 mg/kg body weight). The levels of TBARS (nmol of MDA/mg protein) were determined in the homogenate and microsomes 3 and 5 hr after surgery. Results are expressed as mean ± SE for at least six observations. Sh vitamin-treated show no statistically significant changes with respect to Sh-Control group at all times tested. *p < 0.05 versus Sh. #Statistically significant versus PH-Control.
