Abstract
BACKGROUND: Osteoporosis has been one of the main reasons for old people' s in decline living standard and shortening of lifespan. The onset of osteoporosis is related to the loss of functional coupling in osteoblast and osteoclast. So observation of the regulative effect of medicines on osteoblast is a good method to evaluate their preventive and therapeutical efficacy in osteoporosis.OBJECTIVE: To investigate the effects of genistein on osteoblast culture in vitro.DESIGN: A randomined, controlled and single-blind study based on rat osteoblasts.SETTING: Department of laboratory in amunicipal hospital.MATERIALS: The experiment was completed in the Room of Isotope, Department of Nuclear Medicine, China-Japan Friendship Hospital of Beijing from February to December 2001. Ten SD rats of 24 hours old were provided from Beijing Weitong Lihua Experimental Animal Ltd. Co. (license:SCXK11-00-0008 ). The laboratory was SPF grade.METHODS: Skull osteoblasts of rats were selected to culture in vitro. Microculture tetrozolium, p-nitrophenyl phosphate, atomic absorptiometry and alizarin red were used to observe the effect of genistein on proliferation,activity of alkaline phosphatase(ALP), contents of matrix calcium and the number of mineral nodes of osteoblasts cultured in vitro.MAIN OUTCOME MEASURES: Morphological observation, determination of proliferation ratio, ALP stain, determination of matrix calcium accumulation and number of mineralized nodes with alizarin red stain.RESULTS: It was found that genistein stimulated the proliferation of osteoblasts, improved the ALP activity, and increased the contents of matrix calcium and the number of mineral nodes in cultured osteoblasts.CONCLUSION: Genistein has the effects on stimulating the proliferation,differentiation, maturation and mineralization of osteoblasts cultured in vitro.关键词
