人工种植材料植入组织后的界面反应是种植成败的关键。这与种植材料表面、局部组织以及全身代谢密切相关,一般认为界面反应除受种植体表面20～50A厚的结构影响外。还与其表面能量、氧化膜的形成有关;同时,植入区接触种植体的蛋白构型及组成,尤其是糖蛋白的出现及代谢是影响因素之一。适当的生物分子作为媒介,与生物材料的结合,可产生一种促进各种组织吸附和分化的物质。对这一复杂体系的充分认识,有助于今后复合生物材料的开发、应用。
Artificial planting material implanted in the interface after the organization is the key to planting success. This is closely related to the surface of the planting material, the local tissue and the whole body metabolism. It is generally considered that the interface reaction is influenced by the structure of 20 to 50 A thick on the implant surface. But also with its surface energy, the formation of oxide film; at the same time, implantation of the implant contact with the implant protein configuration and composition, especially the appearance and metabolism of glycoprotein is one of the influencing factors. Appropriate biological molecules as a medium, combined with biological materials, can produce a variety of organizations to promote the adsorption and differentiation of substances. A full understanding of this complex system will help the future development and application of composite biomaterials.
