Femal rats were ovariectomized to build the model of osteoporosis, and then treated with Chinese drugs and stilbestrol respectively for 3 months. The results showed that both Chinese drugs and stilbestrol prevented the BMD, RBS and BTV from further declining in osteoporotic rats; but could not raise the BMD, RBS and BTV that had declined.

用卵巢切除的方法建立大鼠骨质疏松模型，然后对模型分别给乙烯雌酚或中药治疗3个月后发现，乙烯雌酚或中药治疗可以阻止股骨密度，抗弯强度和胫骨骨小梁体积的下降，但两种药物均不能使已经下降的股骨密度、抗弯强度和胫骨骨小梁体积升高。
