Study on preventive effect of jiangu granule on osteoporosis in ovariectomized rats

Abstract

OBJECTIVE: To investigate the preventive effect of Jiangu granule (JGG) on experimental primary osteoporosis type I. METHODS: Osteoporosis model was established through ovary resection of female rats. Bone mineral density (BMD) was measured with double energy X-ray absorptiometry. Level of endocrine markers, including osteocalcin (BGP), estradiol (E2) and calcitonin (CT) in serum were examined by RIA. And uterus parameters was calculated also. RESULTS: JGG could significantly increase BMD and uterus index, improve the levels of E2 and CT in serum, at the same time reduce the BGP level. CONCLUSION: JGG can efficiently prevent type I primary osteoporosis or delay its occurrence by enhancing the function of endocrine system, coordinating the action of calcium related hormone, reducing bone turnover rate and increasing BMD.
