MPO (mu/mg protein)	16.92 ± 0.34	17.13 ± 0.31	24.65 ± 2.2***	18.88 ± 0.93b	19.69 ± 1.54c	16.93 ± 0.59c
CAT (u/mg protein)	146.79 ± 2.9	144.07 ± 2.03	84.89 ± 3.24***	127.9 ± 3.9***a	118.0 ± 3.64***a	134.4 ± 1.88*a
SOD (u/mg protein)	3.37 ± 0.02	3.37 ± 0.01	3.62 ± 0.05***	3.26 ± 0.08a	3.16 ± 0.09a	3.25 ± .0.06a

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 vs control. ^cP < 0.05; ^bP < 0.01; ^aP < 0.001 vs. CIS group.
