Effects of scoparone on the expression of RORγt and related factors in experimental allergic rhinitis rats / 中国耳鼻咽喉头颈外科

ABSTRACT

OBJECTIVE To investigate the effects of behavior, pathology, the serum IL-17, IL-23 level, and the expressing of RORγt, IL-17 and IL-23 mRNA in nasal tissues of experimental allergic rhinitis rats after the scoparone treatment. METHODS The animal model were divided into 4 groups normal control group(group NC), allergic rhinitis group(group AR), artemolactone group(group Sco) and dexamethasone group(group Dxm). The symptom score, HE staining of the nasal mucosa, IL-17 and IL-23 level in serum measured by ELISA, the RORγt, IL-17 and IL-23 mRNA level detected by RTPCR. RESULTS Symptoms and inflammatory pathology were relieved in the experimental group after scoparone treatment. The serum levels of the IL-17, IL-23 in group Sco and group Dxm were little higher than that in group NC. The levels of RORγt, IL-17 and IL-23 mRNA in group AR were significantly higher than that in the other three groups. The levels of RORγt, IL-17 and IL-23 mRNA in group Sco and group Dxm were little higher than that in the group NC. CONCLUSION Sco could significantly inhibited or eliminated the allergy symptoms of AR in rats, and could reduce the severity and inflammatory response of diseases.
