Values are expressed as mean ± SEM of eight rats per group. Concentration is expressed as nmol/mg protein for MDA. Activity is expressed as unit/mg protein for CAT and SOD. Activity is expressed as m unit/mg protein for MPO. Significance was determined by one-way analysis of variance followed by Dennett's t-test: *P < 0.05; ***P < 0.001 versus control. ^cP < 0.05; ^bP < 0.01; ^aP < 0.001 versus CIS group.
