Abstract: ObjectiveTo study the effect of XGS Capsule on the femoral head necrosis in mouse and rat. MethodsThe animal model of femoral head necrosis was caused with tretinoin per os. The free locomotive activity, bone density and pathological changed were observed. ResultsIn the model mouse, the free locomotive activity decreased significantly(P<0.01). In the model rat, the density and weight of the bone also decreased(P<0.01). The defects of cartilage, disorders of ossification and dead bone were observed in the femoral head joint. After treatment with XGS Capsule for 5 weeks, these pathological changes significantly improved. Conclusions XGS Capsule was effective in treating the femoral head necrosis.
