AIM: To establish the influenza infected mouse model and study the anti-inflammatory effect of ganmao shuangjie heji. METHODS: IV FM1 infected mice were used as the animal model. The changes of pathology and the cytokine TNF-?, IFN-? and IL-10 in the lung were observed by HE staining and ELISA (double antibody sandwich enzyme linked immunosorbent assay) after ganmao shuangjie heji treatment. RESULTS: After infected by influenza virus, severe interstitial pneumonia was induced in the model group. Mild interstitial pneumonia was observed in ganmao shuangjie heji treated group. The protein expressions of cytokine TNF-?, IFN-? and IL-10 were higher in model group than those in the control group. The protein expressions of TNF-? and IFN-? in ganmao shuangjie heji treated group decreased and IL-10 expression increased significantly compared with model group. CONCLUSION: Ganmao shuangjie heji decreases the expressions of TNF-? and IFN-?, and increases the expression of IL-10, thus, alleviates inflammatory injury. The clinical application of this medicine can shorten the course of disease.
