We examined effects of a plant polyphenolic compound, curcumin, against fluoride-induced oxidative stress in the rat brain. Five experimental groups of male rats (10 animals each) were compared. Animals of these experimental groups were treated with curcumin (10 and 20 mg/kg body mass), vitamin C (10 mg/kg), and sample solvent (0.5 ml) for a week prior to sodium fluoride intoxication. After treatment, rats of the experimental groups, except for the normal control group, were intoxicated with sodium fluoride (600 ppm through drinking water) for a week. Then, brains were collected and homogenized, and activities of superoxide dismutase and catalase and levels of reduced glutathione and lipid peroxidation final products were evaluated in the brain tissue homogenates. Treatment with curcumin prior to fluoride intoxication significantly normalized the above biochemical parameters; the intensity of protective effects of 20 mg/kg curcumin was close to that of vitamin C.
