表面多孔炭/炭复合材料骨组织改建支架的生物学性能及其表征(英文)

Characterization and biological behavior of a carbon fiber/carbon composite scaffold with a porous surface for bone tissue reconstruction

采用炭/炭复合材料制备了骨组织改建支架,并对所制支架进行了表面形貌观察、痕量元素分析和体内生物学性能评价。结果表明:所制支架能够有效实现对自体移植骨的支撑和骨性融合,生物相容性良好。亦即,表面多孔炭/炭复合材料能够满足作为骨组织改建支架材料的成分要求。

A carbon/carbon composite scaffold for bone tissue reconstruction was prepared. The surface morphology and trace elements of the scaffold were analyzed and its biological behavior was studied both in vitro and in vitro. It was found that the scaffold had a good biocompatibility, not only resulting from its high purity and mild cell toxicity, but also from the excellent integration of the bone tissue with the composite scaffold during the reconstruction.
