摘要
探讨牛蒡子的提取物牛蒡甙对训练大鼠运动能力的影响,以SD雄性大鼠为实验对象,将实验对象分为安静对照组、训练对照组、运动服药组进行对照比较,测试3个组在力竭运动时运动能力、血睾酮含量和血液皮质醇含量的变化。实验结果显示:牛蒡甙可以显著延长大鼠跑台运动力竭时间;大强度训练可以引起血睾酮含量下降和血液皮质醇含量升高,牛蒡甙可以使训练大鼠血睾酮含量显著性增加和血液皮质醇含量显著下降。结论认为,牛蒡甙可以延长大鼠跑台至力竭时间,具有抗疲劳作用;其抗疲劳作用可能与其升高血睾酮和降低血液皮质醇的水平有关。
To investigate the effect of the abstracts of arctiamlappa on the strength exhaustion of the rat,we chose as the subject for experiraent male rats, which were divided into three groups： the inactive group, the active group and the medicine-taking group, and study the kinetism, and the variation of the blood contents of testosterone and blood contents of cortisol of the rats during strength exhaustion. The experiments have yielded the following results： the abstracts of arctiamlappa can greatly lengthen the exhaustion time of the mouse running on the training platform; high intensity training can result in the decrease of the blood contents of testosterone and the rise of blood contents of cortisol; arctiin can increase the rat＇ s blood contents of testosterone and greatly reduce the level of cortisol in the blosd.To conelude, arctiin can lengthen the endurance of the rat nmning on the training platform fill exhaustion time,thus it has the function of resisting fatigue and this function of resisting fatigue may be related to its ability to raise the level of blood contents of the testosterone and decline of the level of cortisol in the blood.
