PROBLEM TO BE SOLVED: To control absorption velocity with which magnesium is absorbed to bone, according to curing condition of an organism.SOLUTION: An organism implement at least possesses a part of highly corrosion-resistant high-purity magnesium metal and a part of lowly corrosion-resistant low-purity magnesium metal. A sustaining period of a needed reinforce function is controlled at a part of the organism implement, and after the period elapsed, the reinforce function of the organism implement is lost.COPYRIGHT: (C)2015,JPO&INPIT【課題】骨に対するマグネシウムの吸収速度を生体の治癒状況に応じて制御する。【解決手段】少なくとも耐食性の高い高純度マグネシウム金属部分と耐食性の低い低純度マグネシウム金属部分とを持つ。生体器具の一部分で必要な補強機能の維持期間を制御し、その期間が経過後、生体器具の補強機能を喪失させるようにしたものである。【選択図】図5
