不同配比羟基磷灰石/胶原海绵复合物作为组织工程支架材料的比较

Journal Title: Di-er Junyi Daxue Xuebao - Year 2008, Vol 29, Issue 3

Abstract

目的:选用不同配比羟基磷灰石和胶原海绵制备成复合材料,研究其结构和生物学特性,为构建组织工程人工胸壁支架材料提供实验依据。方法:按质量比11和12制备不同配比羟基磷灰石/胶原海绵复合材料,纯胶原海绵作为对照,进行扫描电镜检查,观察材料结构特性;进一步进行体内植入试验,通过大体标本检查及组织学检查观察植入材料生物相容性和降解性能。结果:纯胶原海绵呈三维网状结构,胶原蛋白呈细纤维丝状,结构蓬松,强度差;植入体内2周内多孔海绵结构破坏,4周完全降解吸收。12配比羟基磷灰石/胶原海绵复合材料羟基磷灰石粉末与胶原蛋白完全混合均匀,孔径大小100~400 μm;植入体内后生物相容性良好,4周时仍保持多孔结构,8周降解吸收。11配比复合材料羟基磷灰石粒子团聚成块,植入体内可见明显钙磷颗粒聚集,组织反应相对较大。结论:胶原海绵复合一定比例羟基磷灰石后,结构改善,孔径大小适中,在体内保持结构时间及降解时间延长,生物相容性良好,具备开发应用价值,可作为支架材料应用于组织工程人工胸壁的研究。
