Abstract: PURPOSE: Standard rat skull critical bone defects were made and locally continuous infusion of β-NGF animal model was conducted. The effect of β-NGF on bone formation and bone remodeling was evaluated. METHODS: Two 5 mm diameter bone defects were created on the parietal bone of SD rats, the right side was given 10 μg β-NGF PBS solution(experimental group) and the left side was only given PBS solution(control group) via osmotic pump for 7 days. New bone formation was evaluated using H-E staining and Gomori modified trichrome staining. New bone formation in the bone defect of AOI was measured with Image-pro Plus 6.0 software and the data were analyzed using SPSS 19.0 software package. RESULTS: H-E staining showed the new bone formation on the both sides. The results of Gomori modified trichrome staining showed significantly increased new bone formation after application of β-NGF at 21 d and 28 d. The quality of mature bone was significantly higher in the experiment group compared with the control group at 28 d(P<0.05). CONCLUSIONS: Local application of β-NGF during bone healing can promote new bone formation and bone remodeling.
