| Research Abstract |
Although there are many clinical reports that histamine H2-receptor antagonists (H2 blockers) is effective for the treatment of calcific tendinitis and ossification differentiation previously, there is no report about the basic research, the mechanism. We investigated the basic mechanisms of calcification inhibition of the tendon through the H2 blockers in this study. We selected the famotidine for H2 blocker and administrated to the osteoblast cell line MC3T3-E1 and tendon-derived cell lines TTD6 and conformed that famotidine suppressed the calcification in vitro. Next we demonstrated that by using a mouse TTW ,ectopic calcification occurs in the Achilles' tendon in vivo and famotidine suppressed the ectopic calcification. The effect of famotidine for ectopic calcification was also demonstrated on basic medicine.
