Results:(1) CBC possesses a natural trabecular structure. Its components is similar to the mineral of bone.(2) CBC has great cellur biocompatibility. It can promote cell adhesion, proliferation and secretory while needn t modification.(3) In nude mice, the ectopic osteogenesis of MCCAB was obvious which was better than that of CBC alone and the new bone formation increased in pace with time. In the MCCAB, both intramembranous and cartilaginous osteogeneses were seen but the former dominated.(4) When MCCAB was autotransplanted intramuscularly, the osteogenesis was much better than that of negative control groups.(5) The MCCAB can repair autogenous calvaria defects effectively and the effect was much better than that of CBM alone and blank group. Conclusion:(1) CBC possesses good biocompatibility, osteoconduction and porous structure, can be used as scaffold material for constructing of tissue engineering bone.

结果：(1)CBC具有天然的多孔网状结构，最大程度地保持了骨矿的微结构特征，可以作为骨组织工程的支架材料；(2)CBC细胞亲和性好，不需作修饰即能促进成骨细胞的粘附、增殖和分泌活动；(3)MSO/CBC复合人工骨在裸鼠皮下异位成骨作用明显，兼有膜内成骨和软骨内成骨的特点，成骨效果明显优于单纯CBC植入组；(4)MSO/CBC复合人工骨兔自体肌袋异位成骨作用明显，血管化充分，成骨效果明显优于单纯CBC植入组；(5)MSO/CBC复合人工骨修复兔颅骨临界性缺损效果好，明显优于单纯植入CBC组和空白对第四旱区大学硕士学位论文一照组，可以作为骨移植替代材料用于骨缺损畸形修复。

When Fas and c-myc protein were coexpressed in cytoplasm, a strong positive sign appeared in highly differentiated osteosarcoma, fibrous dysplasia of bone and osteoplast of bone callus, a weak sign was found in low-differentiated tumour cells and fibroblasts.

Fas和c-myc蛋白胞浆内阳性，在骨肉瘤的高分化细胞(骨母细胞型和软骨细胞型瘤细胞)和骨化性纤维瘤、骨纤维结构不良、骨痂组织中骨母细胞呈强表达；而在低分化瘤细胞和纤维母细胞则呈弱表达。

The cells of the third stratum were typical mast cells without the tidal line in rat cartilage, cells which arranged into pillar with the distinct tidal line in rabbit cartilage, large irregular cells and coenocytes with the obvious tidal line in human cartilage.
