Basic Study on Enhancement of Antioxidant Function by Low-dose Irradiation in Mouse Brain and Its Combined Effect with Ascorbic Acid

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...
