摘要 目的探讨刺芒柄花素对去势大鼠的雌激素样作用及其对血脂的影响。方法雌性大鼠40只,随机分为5组,即假手术组、模型组、尼尔雌醇组、刺芒柄花素低、高剂量组。去势成功后,予以高脂饮食,同时分别灌胃不同剂量的刺芒柄花素,并以尼尔雌醇和生理盐水作对照,连续用药8w,第8周前5d连续作阴道冲洗脱落细胞涂片。第8周末断头处死大鼠,取子宫并进行子宫指数的测定,同时取血作血脂测定。结果与模型组比较,高剂量刺芒柄花素组阴道细胞涂片可见动情周期变化,促使去势后萎缩的子宫指数回升,子宫内膜增生,血清总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)降低,且这些作用弱于尼尔雌醇;而刺芒柄花素低剂量组无此变化。结论刺芒柄花素在体内具有雌激素样作用,能够改善高脂饮食大鼠的血脂紊乱。
