[High bioactive material-bone graft in bone defect healing]
OBJECTIVE: To assese the value and clinical significance of bioactive material-hydroxyapatite (HA) combined with TGF-beta1 in bone defect healing. METHODS: The applicability of bioactive material-HA granules combined with TGF-beta1 (group A) as a substitute for bone graft was observed in SD rat model. The results were compared with those of HA granules (Group B) and ungrafted bone defect (Group C). RESULTS: Group A demonstrated the highest level of type I collagen mRNA during healing period. CONCLUSION: The bioactive material-HA combined with TGF-beta1 can efficiently bond to ongrowing new bone comparing to HA granules.
