Abstract Objective: To study the therapeutic effect of Fu-ganlin oral liquid on respiratory syncytial virus(RSV) infection in mice. Methods: The 120 ICR mice were randomly divided into 6 groups, which with regular control group, infection model group, Ribavirin group (150 mg/kg), Fu-ganlin oral liquid group 5g/kg, Fu-ganlin oral liquid 10 g/kg group and Fu-ganlin oral liquid 20 g/kg group. These ICR mice were infected by RSV with intranasal infection method to make effective animal models. Then according to the experimental grouping, the treatment of gavage was carried out respectively. And the control group and the infection model group were treated with the same amount of physiological saline, 2 times a day and a total of 6 days . At last, we used HE staining to observe pathological changes in mice by Fuganlin oral liquid treatment after 6 days. In addition, IFN-β, IL-6 content and gene expression level with infected mice in alveolar lavage fluid and lung tissue were analyzed by ELISA and real time fluorescence quantitative PCR methods during the treatment. The peripheral blood was sampled and detected CD3+CD4+ and CD3+CD8+ levels after heparinization with flow cytometer Results: The mouse model of RSV infection was successfully established. The pathological results of HE staining showed that the pathological changes of lung tissue in different treatment groups were improved, and the Fu-ganlin oral liquid 10 g/kg and 20 g/kg groups in the mice were most significantly improved in the lung tissue. The level of IFN-β, IL6 and gene expression of mice lung tissue decreased gradually, and the peripheral blood level of the above inflammation factors in each treatment group was compared with the control group. Among them, The level of CD3+CD4+ in the model group, Ribavirin group and the Fu-ganlin oral liquid 5 g/kg group increased significantly(P<0.05); the CD3+CD4+ of the Fu-ganlin oral liquid 10g/kg and the 20 g/kg group decreased significantly(P<0.05). And the levels of CD3+CD4+/CD3+CD8+ in the model group increased significantly(P<0.05),the Fu-ganlin oral liquid 20 g/kg group were significantly decreased(P<0.05),the levels of CD3+CD4+/CD3+CD8+ in the Ribavirin group, Fu-ganlin oral liquid 5 g/kg and 10 g/kg groups had no significant difference. Conclusion: The treatment group of "Fuganlin oral liquid " has a promising therapeutic effect on RSV infection in mice in a dose-dependent manner. The effect of high dose group is more significant.
