Objective: This study is to learn the effects of Hataedock method using Coptidis rhizoma and Glycyrrhiza uralensis mixed extract on inflammatory response in allergic rhinitis-induced obese NC/Nga mice.
Materials and Methods: The mice were fed with high fat-diet to be obese, and were divided into 3 groups as follows; allergic rhinitis-induced obese mice group with Hataedock method (CGT, n=10), no treatment group (Ctrl), allergic rhinitis elicited obese mice group (ARE). To induce allergic rhinitis, NC/Nga mice of 3 weeks age were sensitized on 7, 8 and 9 weeks by ovalbumin antigen in intraperitoneal space. After 7 days of final sensitization, allergic rhinitis was initially induced in mice through nasal cavities for 5 days. After 1-week, allergic rhinitis was induced again by the same method. Histological examination was used to identify distribution of IL-4, CD40, STAT6, Fc?RI, substance P, MMP-9, NF-κB p65, iNOS and COX-2.
Results: Hataedock method significantly reduced IL-4, STAT6 and CD40 response (p<0.05). In CGT, the inhibition of Th2 differentiation decreased inflammatory mediators such as Fc?RI, substance P, MMP-9, NF-κB p65, iNOS and COX-2 (all p<0.05). The immunological improvement led reduction of respiratory epithelial damage and mucin secretion in goblet cell.
Conclusion: The results of this study show that the Hataedock method suppresses the expression of allergic rhinitis by decreasing the inflammatory mediators through the regulation of Th2 differentiation even when the inflammation reaction is increased by obesity. Therefore, Hataedock may have potential preventive measure of allergic rhinitis accompanied by obese.
