RESUMO
Objective: To investigate the effects of Kangguzhe Formula(KGZF) on promoting union of experimental rat fracture.Methods: The experimental rat fracture models were reproduced by cannon born injure,continually treated with KGZF 21d by oral administration.The X-ray,pathological histology and anti-fracture intension of fracture union tissue were detected to investigate the effects of KGZF.Results: KGZF can significantly improve the osteotylus rebuild,trabeculation of bone and concentrated osteoblasts of fracture tissue;X-ray detection also showed that it can increase the grade of X-ray and anti-fracture intension of fracture union tissue;Compared with model group,it had significant difference.Conclusion: KGZF can obviously improve the union of experimental rat fracture.
