2Cm bone defect was established in ulna of rabbits, the capacity of different therapeutic measures in bone defect repairment was determined in groups A , B (implanted BMP, TGF -β〓 and carrier) and C . It was found that the appearance of osteoblasts and formation of bone union were earlier and the number of osteoblasts more in group B than in group A. The amino acid analysis revealed that the volume of ossein was significantly higher in group B than in group A at the early stage.
