Abstract
Disclosed is an artificial bone material having controlled calcium ion elution, which does not induce cytotoxicity or any inflammatory response. It is found that the elution of a calcium ion from an artificial bone material for transplantation which contains a calcium-containing substance can be prevented effectively by subjecting the carrier to a surface treatment or adding a surface-treating agent to the carrier. It is also found that the induction of cytotoxicity can be prevented and the induction of an inflammatory response can also be prevented by using the above-mentioned carrier having controlled calcium ion elution.
