竹叶提取物对小鼠运动能力的影响

Effects of Bamboo Leaves Extracts on Exercise Ability in Mice and Its Possible Mechanism

旨在研究竹叶提取物对小鼠运动能力的影响。选取8周龄健康雄性小鼠45只随机分为阴性对照组、模型组和试验组,检测骨骼肌和心肌组织中丙二醛(MDA)的质量摩尔浓度,并测定超氧化物岐化酶(SOD)和过氧化氢酶(CAT)的活性。结果表明,试验组小鼠游泳至力竭的时间显著大于模型组。与阴性对照组相比,运动训练后,模型组小鼠骨骼肌和心肌组织中的MDA质量摩尔浓度上升,试验组下降;模型组小鼠骨骼肌和心肌组织中的CAT活性下降,试验组升高;试验组和模型组的SOD活性升高。说明竹叶提取物具有改善运动能力和抗氧化的功能。

To study effect of bamboo leaves extracts on the exercise ability of mice.A total of 45 healthy male mice aged 8 weeks were randomly divided into negative control group,model group,experimental group.Malondialdehyde（MDA）molality,superoxide dismutase（SOD）and catalase（CAT）activities in the skeletal muscle and myocardium tissue of mice were then measured.The time of swimming to exhaustion in the experimental group was significantly larger than that in the negative control group and the model group.After exercise training,compared with the negative control group,the molality of MDA in skeletal muscle and myocardium of mice in model group was higher than that in negative control group,and the molality of MDA decreased.Compared with the negative control group,the activity of CAT decreased in the model group after exercise training,and the activity of CAT in the experimental group increased.Compared with the negative control group,the activity of SOD increased in the model group after exercise training,and the activity of SOD in mice of the experimental group significantly enhanced.In the mouse model,the extract of bamboo leaves plays an important role in anti fatigue,anti-oxidation,and avoiding the damage of bone and myocardium,the results suggest that the extracts of bamboo leaves have a certain capacities in improving exercise and antioxidation abilities.
