Özet

Brain damage is a major complication of fulminant hepatic failure. d-Galactosamine (d-GalN)-induced liver toxicity causes damage to brain. The effects of vitamins and selenium mixture against d-GalN stimulated brain injury were investigated in this study. Sprague-Dawley female rats aged 2.0-2.5 months were used for the study. The rats were divided into four categories. A 0.9% NaCl solution was intraperitoneally given to the experimental rats in the first group. Using gavage technique, the second group of animals were subjected to a formulation consisting of 100 mg center dot kg(-1)center dot day(-1) vitamin C, 15 mg center dot kg(-1)center dot day(-1) of beta-carotene, 100 mg center dot kg(-1)center dot day(-1) of alpha-tocopherol in addition to 0.2 mg center dot kg(-1)center dot day(-1) of sodium selenate for 3 days. The third group was given a single dose of d-GalN hydrochloride at the concentration of 500 mg center dot kg(-1) through a saline injection. The final group was given similar concentrations of both the antioxidant combination and d-GalN. Tissue samples were collected under ether anesthesia. The rats treated with d-GalN showed brain damage; increased myeloperoxidase, catalase, glutathione peroxidase, glutathione-S-transferase, lactate dehydrogenase, and superoxide dismutase activities; and decreased glutathione levels. Treatment with vitamins and selenium combination resulted in alleviation of these alterations in the rats. These findings suggest that administration of the vitamins and selenium combination suppresses oxidative stress and protects brain cells from injury induced by d-GalN.
