EFFECTS OF RGD-POLYPEPTIDE(224) ECHISTATIN AND 17?-ESTRODIOL ON OSTEOCLASTIC BONE RESORPTION ACTIVITIES / 解剖学报

ABSTRACT

Objective This study is to understand the effects of RGD\|peptide(224), Echistatin and 17 ? estrodiol on bone resorption. Methods RGD\|polypeptide (224) (RGD), Echistatin(Ech) and 17 ? estrodiol (E\-2) were added into osteoclast like cells (OLC) and ivory bone slices co\|cultured system. Results It has been found that 10 -7 mol/L RGD, Ech and E\-2 decreased the number of resorption lacunae, resorption area and resorption cave on bone slices in various degrees.Conclusion RGD, Ech and E\-2 inhibits the bone resorption activities in various degrees.
