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.
镁是一种对人体无害的必需微量元素。镁材料作为一种性质与天然骨相似的轻质金属，具有可降解性、低生物毒性以及其调控强度和可控降解速度的特点。在组织充分愈合后，可以避免二次手术的负担。因此，有必要研究镁及其合金作为医用生物材料的可能性，而对其生物活性的研究是进一步应用的基础。本文综述了镁及其合金的生物活性。
