We examined the effects of irradiation (50 cGy of gamma-ray) reducing the oxidative damage in carbon tetrachloride (CCl4)-hepatopathy mice. We made pathological examinations and analyzed transaminase activity (glutamic oxaloacetic transaminase and glutamic pyruvic transaminase), lipid peroxide level and the activities of endogenous antioxidants in the mouse. The irradiation was found to accelerate the recovery. Based on pathological examination as well as changes in each transaminase activity and lipid peroxide levels, it was shown that hepatopathy improved 3 d after the irradiation. The activities of glutathione reductase and glutathione peroxidase rapidly elevated after irradiation, and the total glutathione content gradually increased in the irradiation group. Both activities of gamma-glutamylcysteine synthetase and catalase were higher than normal at all times after the irradiation and gradually increased. In addition, the gamma-glutamylcysteine synthetase activity changed In a similar fashion to the total glutathione content. However, superoxide dismutase activity in bath groups decreased and that of the irradiation group was significantly lower than that of the sham-irradiation group. These findings suggest that low-dose radiation relieved functional disorder at least in the liver of mice with active oxygen diseases. (C) 1999 Elsevier Science Inc.
