AR mice model was established by OVA, and IL-4 and IFN-<em>γ</em> contents can be measured with ELISA. The morphological changes of nasal mucosa were observed by hematoxylin eosin (HE) staining and NF-<em>κ</em>B expression in the nasal mucosa of mice was tested with Real-Time PCR and Western blot. <strong>Results:</strong> Compared with the model group, the nasal symptoms in the Yupingfengsan Oral Liquid group and Loratadine group were obviously relieved. HE staining showed that there was a little inflammatory cell infiltration in the nasal mucosa of Yupingfengsan Oral Liquid group and Loratadine group and it was significantly reduced when compared with the model group. IL-4 level in the serum and expression of NF-<em>κ</em>B protein and gene in the nasal mucosa was consistent and it was decreased when compared with the model group (P < 0.01), but the IFN-<em>γ</em> level in the serum was increased (P < 0.01). <strong>Conclusion:</strong> Yupingfengsan Oral Liquid can improve the clinical symptoms and histopathological manifestations of AR mice sensitized by OVA, inhibit the NF-<em>κ</em>B expression, balance the percentage of Th1/Th2 cells, increase the IFN-<em>γ</em> level in the serum and decrease the IL-4 level.展开更多
