摘　　要：目的:探讨不同磁场对大鼠肝组织中超氧化物歧化酶(SOD)活力、丙二醛(MDA)含量的影响。方法:用邻苯三酚法测定SOD活力,TBA法测定MDA。结果:在30mT磁场中曝磁30分钟,大鼠肝组织中SOD活力显著高于对照组(P<0.01),大鼠肝组织MDA含量显著低于对照组(P<0.01)。结论:30mT旋磁场对大鼠肝脏组织SOD活力、MDA含量有一定影响。Objective ：To study the effect of rotating magnetic field on the activity of superoxide dismutase（SOD）, the contentsmalon -dialdehyde（MDA） and nitric oxide（NO） in the liver and heart tissues of rats. Methods： SOD activity was determined with Trihy -droxy benzene, MDA was determined with TBA（ Thih bar bituric Acid）. and NO content was determined with Griess method. Results ： 30 mins after exposing to 30 mT magnetic field, SOD activity in the liver and heart tissue of rats was obviously higher than that in the control group（ P 〈0.01 ） i. The content of malon - dialdehyde（MDA） in the liver tissue of rats was remarkably lower than that in the control group（ P 〈 0.01 ）. Conclusion： 30 MT rotating magnetic field has some effect on SOD activity, the content of malon - dialdebyde（MDA） and nitric oxide （NO） in the internal organs of rats.
