摘要 目的观察白藜芦醇在体内的雌激素效应及对血脂的调节作用。方法成年雌性SD大鼠随机分为6组:假手术组、单纯去卵巢(OVX)组、17β-雌二醇组(ERT,0.1mg·kg-1·d-1)、高剂量白藜芦醇组(RH,40mg·kg-1·d-1)、中剂量白藜芦醇组(RM,20mg·kg-1·d-1)、低剂量白藜芦醇组(RL,10mg·kg-1·d-1)。除假手术组外各组均切除卵巢,术后1w开始给药,观察阴道脱落细胞涂片、动情周期改变,连续8w。处死大鼠后检测血脂四项,测量子宫重量,观察子宫内膜及腺体变化。结果与假手术组比较,OVX组大鼠阴道上皮细胞角化率、子宫系数明显降低(P<0.05),子宫内膜及腺体萎缩,高密度脂蛋白胆固醇(HDL-C)降低(P<0.05)。白藜芦醇能使去卵巢大鼠阴道上皮细胞角化率、子宫系数及腺体增加(P<0.05),子宫内膜增厚,血清HDL-C升高(P<0.05)。结论白藜芦醇具有弱雌激素样作用,能减轻雌激素缺乏导致的生殖系统萎缩,改善血脂代谢,对防止动脉硬化可能有效。
