目的：觀察骨康寧對(duì)骨質(zhì)疏松的防治作用。方法：采用im地塞米松（DEX）導(dǎo)致大鼠形成骨質(zhì)疏松。結(jié)果：與模型對(duì)照組比較，骨康寧明顯升高骨質(zhì)疏松大鼠的骨質(zhì)量、骨密度、骨強(qiáng)度、骨體積（TBV）、灰質(zhì)量、骨鈣、骨磷，明顯降低尿鈣。結(jié)論：骨康寧對(duì)大鼠骨質(zhì)疏松具有明顯的防治作用。

Objective: To investigate preventive and therapeutic effect of Gukangning on osteoporosis induced by dexamethasone (DEX). Methods: Osteoporosis was induced by im injection of DEX in rats. Results: Experiments showed that Gukangning could evidently increase bone weight, bone mineral density, bone strength, TBV, ash weight, bone calcium, and bone phosphorus, and decrease urine calcium as well. Conclusion: Gukangning has remarkably preventive and therapeutic effects on osteoporotic in rats.
