OBJECTIVE: To explore the role of sinomenine in treatment of allergic rhinitis mice model and its possible mechanism. METHOD: We used ovalbumin (OVA) to make allergic rhinitis model of BALB/c mice. Saline was used in the control group. When we challenged the mice with OVA intranasally, the mice in sinomenine treatment group were feed by the food containing sinomenine. Mice were then killed 24 h after the last OVA challenge. The noses of mice from each group were removed en bloc and fixed, then each section was stained with hematoxylin and eosin. ELISA assay was used to measure the concentration of anti-OVA IgE, IL-4 and IFN-gamma. The proteins expressive level of T-bet and GATA3 were examined. RESULT: Nasal mucosa of the mice in sinomenine treatment group were not hyperplasia and without obvious infiltration of eosinophils. The concentration of anti-OVA IgE, IL-4 and IFN-gamma in the serum and T-bet and GATA3 expression levels of sinomenine treatment group were lower than those of allergic rhinitis group. CONCLUSION The sinomenine can be used to treat allergic rhinitis mice, and the mechanism may rely on the improvements of the Th1/Th2 imbalance.
