Mice were irradiated by 831MeV ,12,C,6+, ions to 0.05, 0.1, 0.3, 0.5, 0.75, 1, 1.5, 2.0Gy, respectively. On 5th day after the irradiation, (Superoxide dismutase, SOD) activity and (Maleic dialdehyde, MDA) content in serum and liver and (Glutathione, GSH) level in brain were determined. The results show that in comparison with the control, the SOD activity in serum and liver increased significantly in groups received less than 0.75Gy, but decreased obviously in groups irradiated to 0.75Gy or larger doses; the MDA content in serum and liver decreased significantly in groups of 0.3Gy or less doses, but increased obviously in groups of 0.3Gy or larger doses; the GSH level in brain tissue increased in groups of less than 0.5Gy, but decreased in groups of greater than 0.5Gy. Therefore, the low dose,12,C,6+, ions irradiation can trigger off the antioxidant system in multi-tissue of mice, while the high doses irradiation can impair the antioxidant system.
