Abstract: Study the effects of exposure to ultra high static magnetic fields on antioxidation and immune functions of mice. Four-week old mice were exposed to the static magnetic fields with magnetic intensity of 12 Tesla (T) for 2 hours every day, and continued for 7 days. On the ninth day, the mice were sacrificed. Livers and kidneys were taken to measure the activity of Catalase (CAT), Superoxide Dismutase (SOD), Total antioxidant capacity (T-AOC), Glutathione peroxidase (GSH-Px) and the content of Maleic Dialdehyde (MDA). Also, thymus and spleen were obtained to measure their index and the splenic lymphocyte proliferation. Besides, blood of mice was collected by taking the eyeball and the content of white cells in the peripheral blood of mice was detected. Compared to control group, activity of CAT, SOD, T-AOC and GSH-Px in kidney in the experiment group were increased significantly. The content of MDA was decreased significantly. Activity of SOD and GSH-Px in liver was enhanced, and the content of MDA decreased significantly. Furthermore, splenic lymphocyte proliferation was increased, and the index of thymus and the content of white cells in peripheral blood were increased remarkably. Exposure to ultra high static magnetic fields can improve antioxidation and immune functions of mice.
