Abstract
目的:观察去卵巢骨质疏松症大鼠下丘脑Leptin蛋白水平,探讨绝经后骨质疏松症(Postmenopausal Osteoporosis,PMOP)的发病机制以及补肾中药复方的疗效机理.方法:去卵巢复制骨质疏松症大鼠模型,实验设正常组、模型组、假手术组、补肾中药复方组、钙尔奇D组、骨疏康组,灌胃给药12周.应用XR-36型双能X线骨密度仪测定股骨骨密度,Western Blot检测下丘脑Leptin蛋白水平.结果:与正常组比较,模型组股骨骨密度明显降低,下丘脑Leptin蛋白水平明显升高;与模型组比较,补肾中药复方组、骨疏康组股骨骨密度明显升高;补肾中药复方组下丘脑Leptin蛋白水平明显降低.结论:下丘脑Leptin蛋白水平升高可能是PMOP发病的机制之一;补肾中药复方可能通过降低下丘脑Leptin蛋白水平,有效防治PMOP,其作用优于钙尔奇D和骨疏康.
