用珊瑚人工骨和自体骨髓复合移植修复兔下颌骨实验性骨缺损，术后行Ｘ线、核素骨显像和组织学检查。结果发现：复合珊瑚骨移植术后６周有明显的成骨现象，１２周骨缺损被修复。复会珊瑚骨移植成骨作用明显优于单纯珊瑚骨移植。实验结果表明，珊瑚骨与骨髓复合为成骨作用提供支架、成骨细胞和骨诱导物质，加速骨缺损的修复，是一种良好的骨代用品。 The coralline bone graft and autologous bone marrow transplantation were used to repair the experimental bone defects of the mandible in rabbits. X-ray, radionuclide bone imaging and histological examination were performed after operation. The results showed that there was obvious osteogenesis at 6 weeks after composite coralline bone transplantation and bone defects were repaired at 12 weeks. Osteogenesis of the coral bone graft was better than that of pure coral bone graft. The experimental results show that the coral bone and bone marrow complexes provide a scaffold for osteogenesis, osteoblasts and osteoinductive substances, to accelerate the repair of bone defects, is a good bone substitute.
