Abstract:
Objective To study the effect of Taohongsiwu decoction(THSWD) on the VEGF expression and the micrangium regeneration of callus tissue in bone stump. Methods 65 Japanese rabbits were divided into four groups randomly, three groups were given orally with THSWD, Yandining tablet, distilled water respectively after the right radial bone fracture model was established by operation, and the other group served as control. At the 7th,15th,21th and 35th day after fracture, immunohistochemical method was used to detect the expression of VEGF, and the histochemical staining was used to detect the micrangium change of callus tissue in bone stump. Then the data were compared and analysed. Results VEGF expression level was higher in THSWD intvervening group than that in the other groups, and the decrease of VEGF expression was not obvious after the peak value at 15th day. The callus micrangium regeneration and the remodeling of callus in THSWD intervening group were better in all phase than those in the other groups. Conclusion THSWD could improve the VEGF expression of callus tissue, accelerate the micrangium regeneration in bone stump and promote the healing of fracture.
