Abstract

In order to compare the induced time of osteoporosis between ovariectomized and neurectomized models in ddY mice. Experimental groups were divided into Sham, ovariectomized (OVX group) and neurectomized (NX group) group. The changes of body weight, tibia weight and histomorphometry of epiphyseal regions of tibia that were generally used as criteria index in osteoporosis, were evaluated at 2 and 4 weeks after operations with other generally used index-changes of serum osteocalcin. Also, calcium and phosphorus levels in the ash tibia were demonstrated with their ratio (Ca/P ratio). From the result of this study, evidences which reflect osteoporotic states of animals such as decrease of absolute and relative tibia weight, histomorphometrical index of epiphyseal region of tibia including trabecular bone volume %, and calcium and phosphorous contents in tibia, were generally detected from 4 weeks after ovariectomy and 2 weeks after neurectomy with increase of serum osteocalcin levels. In conclusion, it is considered that more rapid and favorable osteoporosis was induced in neurectomized model compared to that of ovariectomized model.
