Abstract:
Objective To observe the effects of inducing ossification in necrotic femoral head by VEGF. Methods Healthy rabbits were lesioned into necrotic femoral head by liquid nitrogen and randomly assigned for AdhuVEGF_(121) gene transfection into the necrotic femoral head and AdTrackCMV transfection. The alkaline phosphatase (ALP) activity before transfection and day 1, week 1, 2, 4, 6, 8, 12 after transfection and the expression of collagen Ⅰ at week 2, 4, 8, 12 was examined by enzymology and immunohistochemical techniques. Results The ALP activity of the AdhuVEGF_(121) group was significantly higher than AdTrackCMV group (P
