目的:探讨运动对多囊卵巢综合征(PCOS)大鼠胰岛素、性激素和卵巢形态学的影响。方法:17只21日龄Wistar大鼠随机分为PCOS运动组(n=6)、PCOS非运动组(n=6)和非PCOS对照组(n=5)。注射丙酸睾酮诱导PCOS模型,对照组注射相应容积茶油。运动程...目的:探讨运动对多囊卵巢综合征(PCOS)大鼠胰岛素、性激素和卵巢形态学的影响。方法:17只21日龄Wistar大鼠随机分为PCOS运动组(n=6)、PCOS非运动组(n=6)和非PCOS对照组(n=5)。注射丙酸睾酮诱导PCOS模型,对照组注射相应容积茶油。运动程序为每天游泳2h,连续15d。实验结束后取血测定葡萄糖、胰岛素、雌二醇、黄体酮和睾酮浓度;卵巢病理切片运用图像分析软件Image-Pro Plus 6.0进行形态学分析。结果:PCOS运动组胰岛素、雌二醇和睾酮水平均显著低于非运动组(P<0.05),空腹血糖与空腹胰岛素(FBG/FINS)比值显著高于非运动组(P<0.05),接近于对照组水平。血糖和血清黄体酮水平三组间差异没有显著性。卵巢病理显示,PCOS运动组窦前卵泡数和闭锁卵泡显著减少(P<0.05),而窦状卵泡和黄体数目则显著升高(P<0.05),均接近于对照组水平。结论:短期运动能改善PCOS大鼠胰岛素敏感性,降低血清雄激素和雌激素水平,恢复正常卵巢形态,提示运动是PCOS的基础治疗方法。展开更多
