The effect of melatonin on CAT activity in rats subjected to whole body gamma irradiation. Data represent mean ± standard error on the mean (SEM) for 5 animals per group. Con: Control group, Veh: Vehicle only group, Mel: Melatonin only group, Rad: Radiation only group, Veh + Rad: Treated with vehicle and exposed to 10 Gy radiation, and Mel + Rad: Treated with 100 mg/kg melatonin before exposure to 10 Gy radiation. ^a P < 0.001 when compared to Control group. ^b P < 0.001 when compared to the Radiation only group.
