We examined whether the bone resorption induced by PGE2 was inhibited by SrCl2 using 45Ca-labelled calvaria of CD-strain mice in tissue culture. It was found that Sr salts inhibited physiological bone resorption in a dose-dependent manner (0.1-5.0 mM) and did not act via PGE2. Accordingly, it was suggested that Sr salts did not inhibit bone resorption induced by exogenous PGE2.
我们使用组织培养中的CD品系小鼠的45Ca标记颅骨,研究了SrCl2是否能抑制PGE2诱导的骨吸收。结果发现,Sr盐以剂量依赖性方式(0.1 - 5.0 mM)抑制生理性骨吸收,且并非通过PGE2起作用。因此,提示Sr盐不能抑制外源性PGE2诱导的骨吸收。
