【摘要】 采用扫描电镜、X线能谱分析及钙、磷元素微区含量测定等手段 ,对 HA- b BMP- Co和 HA- Co两种不同复合人工骨材料整复节段性骨缺损的机理进行了初步探讨。结果表明 :HA- b BMP- Co复合人工骨具有骨诱导和骨引导的双重作用。除术后 2周磷元素含量无显著性差异外 ,其后同一观察期内 ,HA- b BMP- Co组受植区钙、磷元素含量明显高于 HA- Co组 ,两组间差异有显著性 (P<0 .0 5 )更多还原

【Abstract】 The scanning electric microscopy (SEM). X ray energy graph and Ca, P contents analysis were adopted in studying the mechanism and superiority of two different composite artificial bones (HA bBMP Co and HA Co) to repair segmental bone defect in rabbits. The results indicated that HA bBMP Co had a double effects of bone induction and bone conduction. No difference of P content in two weeks after reconstructive surgery was found, but in other periods, there was an obvious difference in Ca and P content between HA bBMP Co group and HA Co group (P<0.05).\;更多还原
