Abstract
We examined whether the bone resorption induced by PGE2 was inhibited by SrCl2 using45Ca-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.
