We studied on the characteristics of changes in antioxidant function of mice brains at 4 h to 7 days after low-dose X-ray (0.1 to 2.0 Gy) irradiation, and the combination effect of this and administration of ascorbic acid (500 mg/kg body weight), an antioxidant enzyme. As a result, low-dose irradiation mostly showed decrease in lipid peroxide levels, increase in superoxide dismutase (SOD) activities and heat shock protein (HSP) levels. In addition, the combined use of 0.5 Gy irradiation with ascorbic acid administration showed a significant decrease in lipid peroxide level, suggesting the combined effect of antioxidant.
