摘要
镁是一种对人体完全无害的元素,是人体所必须的微量元素。镁与骨骼有相似的性质,作为一种轻金属,镁材料具有可降解、生物毒性小、强度可调节、降解速度可控等特性,还可避免二次手术带来的负担。因此,需要研究镁及其合金作为医用生物材料的可行性,而其生物活性的研究是其能否进一步应用的基础。本文对镁材料的生物活性即材料与组织的界面能否发生特殊生理反应的组织相容性,做以下综述。
Magnesium is an essential microelement which is not harmful to human body. As a light-weight metal with properties similar to natural bone magnesium material possesses the characteristics of its degradability, little biotoxicity, as well as its regulatory strength and controllable degradation-speed. After the tissue has healed sufficiently, the burden of a second surgical procedure can be avoided. Therefore, there is need of investigation on the possible use of magnesium and its alloys as medical biomaterials, and the study of its bioactivity is the foundation of further application. This article reviews the bioactivity of magnesium and its alloys
