红景天联合多维元素对小鼠运动性疲劳的影响

目的：观察红景天联合多维元素对小鼠运动性疲劳的影响。方法：似随机抽样法将40只雄性小鼠分为4组，分别为空白对照组、红景天（质量浓度为0．78g·kg^-1）联合多维元素（质量浓度为0．21g·kg^-1）低剂量组、红景天（质量浓度为1．56g·kg^-1）联合多维元素（质量浓度为0．42g·kg^-1）中剂量组、红景天（质量浓度为3．12g·b^-1）联合多维元素（质量浓度为0．84g·kg^-1）高剂量组。对4组雄性小鼠连续灌胃给药7d后，测定小鼠负重游泳时间、血乳酸浓度、肝糖原含量3个指标。结果：红景天联合多维元素能延长小鼠的负重游泳时间、降低血乳酸浓度、提高肝糖原含量。结论：红景天联合多维元素对小鼠具有抗运动性疲劳作用。

Effect of Rhodiola Rosea Extract Combined with Multivitamin Formula with Minerals on Exercise-induced Fatigue in Mice

OBJECTIVE：To observe the effect of Rhodiola Rosea extract combined with multivitamin formula wiih minerals on exercise-induced fatigue in mice. METHODS：A total of 40 male mice were randomly assigned to receive Rhodiola Rosea extract combined with multivitamin formula with minerals （ low dose ： Rhodiola Rosea extract 0. 78 g·b^-1 plus multivitamin formula with minerals 0. 21g·b^-1 ;middle-dose： Rhodiola Rosea extract 1.56 g·b^-1 plus multivitamin formula with minerals 0. 42 g·b^-1; high-dose： Rhodiola Rosea extract 3. 12 g·b^-1 plus multivitamin formula with minerals 0. 84 g·b^-1） or placebo （blank control） intragastrically for 7 consecutive days, then the weight- loaded swimming time as well as blood lactic-acid level and liver glycogen level were determined. RESULTS：Rhodiola Rosea extract combined with multivitamin formula with minerals resulted in longer weight-loaded swimming time, lower blood lactic-acid level and increased liver glycogen level than did blank control. CONCLUSION： Rosea extract combined with multivamin has anti-fatigue effect in mice.
