Objective:There are many methods to test the activity of superoxide dismutase.In our country,the method of pyrogallol self-oxidation was used.Two kinds of this method,one is classical method known as 420 nm method;the other is improved micromethod known as 325 nm method.

目的 ：超氧化物歧化酶的测活方法很多，目前国内多采用连苯三酚自氧化法，本方法有两种，一种是经典的Marklund连苯三酚自氧化法，简称 42 0nm法；另一种是对 42 0nm法作了改进的微量连苯三酚自氧化法，简称 32 5nm法。

Opuntia Milpa Alta prolonged the exhausted swimming time of mice notably, strengthened the LDH activity, accelerated the removing of the LA and BUN, strengthened the SOD activity of liver and skeletal muscle, accelerated the removing of the MDA content of liver and skeletal muscle, demonstrated positive Anti-Movement-Fatigue function. We inferred one of Anti-Movement-Fatigue mechanism was that Opuntia Milpa Alta could increase the exercise ability and load adaptive capacity of the organism and accelerate the removing of metabolites.

米邦塔仙人掌能显著延长运动组小鼠力竭游泳时间，增强运动小鼠的乳酸脱氢酶活性，加快血清乳酸和尿素氮的清除，增强运动小鼠肝脏、骨骼肌超氧化物歧化酶活性，加快肝脏、骨骼肌丙二醛的清除，显示出了积极的抗运动性疲劳作用，并推测其抗运动性疲劳的机制之一是通过增强机体运动能力和负荷适应能力，加快代谢产物的清除起作用。
