Impact of Yupingfengsan Oral Liquid on the Expression of IL-4, IFN- γ and NF- κ B of Allergic Rhinitis Mice
2021
To observe the impact of Yupingfengsan Oral Liquid on the expression of IL-4 and IFN-γ in AR mice’s serum and expression level of nuclear factor—κB (NF-κB) protein and gene in nasal mucosa. Method: Forty BALB/c mice were randomly divided into the normal group, model group, Yupingfengsan Oral Liquid group (6 g/kg) and Loratadine group, with 10 mice per group. AR mice model was established by OVA, and IL-4 and IFN-γ contents can be measured with ELISA. The morphological changes of nasal mucosa were observed by hematoxylin eosin (HE) staining and NF-κB expression in the nasal mucosa of mice was tested with Real-Time PCR and Western blot. Results: 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-κB protein and gene in the nasal mucosa was consistent and it was decreased when compared with the model group (P γ level in the serum was increased (P κB expression, balance the percentage of Th1/Th2 cells, increase the IFN-γ level in the serum and decrease the IL-4 level.
