中文摘要	This paper describes the structures of beta -TCP, beta -TCP/DCHA and HA, tests and analysis for their surface bioactivity and osteoblast attachment and the evaluation structure before or after implantation used by micro-CT test. The bone marrow stromal cells were cultured, or separation and proliferation were made to reach up to osteoblast concentration of 10/sup 5//cm/sup 3/, and then the osteoblasts were immersed in the biomaterials and implanted in the rabbits. The bone formation was observed and the mechanism of new bone formation was investigated. The experimental results after implantation show that introducing new bone grows into the scaffold holes, and scaffolds were degraded with new bone formation and growth. In the end, the bone was reconstructed. The results indicate these tissue-engineering scaffolds possess 3-D porous structure, pore size appropriate new bone growth, degradable, high bioactive and inducing new bone formation.
