Abstract: PURPOSE:To permit the self coagulation hardening in an early stage and the adhesion fixation without inducing the inflammation reaction for a living body texture and stabilize joint by constituting the cement for living body from an aqueous solution containing crystalline glass powder containing Ca as constitution component phosphate as main component. CONSTITUTION:Since the aqueous solution containing phosphate as main constituent is mixed with the crystalline glass powder containing Ca as constitution component, the Ca<2+> ion dissolved to the surface or the periphery of the powder and HPO ion in a hardening liquid containing phosphate as main component react, for example apatite hydroxide is formed through the fore-material such as noncrystalline calcium phosphate, and hardening occurs. Apatite hydroxide possesses the superior chemical bonding property with the living body bone, and the stable material in the living body is formed. Further, each of the crystalline glass powder and the glass powder has different eluation speed of Ca<2+> ion, and the glass powder possesses the larger elution speed. The hardening time can be adjusted by the combination of the HPO ion concentration in the hardening liquid.
