【摘要】 目的：研究低频电磁场对衰老大鼠的作用，并探讨其机制。方法：采用50Hz交变磁场作用衰老大鼠，观察大鼠机体内超氧化物歧化酶（SOD）和丙二醛（MDA），大鼠的耐乏氧能力和耐力的变化。结果：经过50Hz交变磁场作用的大鼠耐乏氧力增加，耐力增强，其体内SOD的活力明显增加，MDA的含量下降。结论：低频50Hz交变磁场对衰老大鼠具有增强其抗氧化、抗疲劳作用和抗乏氧能力。更多还原

【Abstract】 Objective the effects of low-frequency electromagnetic fields to antioxidation capacity in old rats and elucidate the mechanism of the effects. Methods Left the oldrats in low -frequency(50Hz) electromagnetic field, detected the SOD and MDA in rats, and observed their anoxia-resistivity and endurance. Results In the rats which were exposed to low-frequency electromagnetic field, the SOD activity, anoxia-resistance and endurance were significantly increased and the MDA was decreased. Conclusion Under the influence of low-frequencyelectromagnetic field, the ability of antioxidation, anoxia-resistance and endurence of old rats areenhanced.更多还原
