Objectives : Gumiganghwal-tang and its main components have been used for treatment of cough, headache, joint pain and fever. Using a respiratory inflammatory model, we intend to demonstrate the its antiinflammatory effect and immune mechanism of Gumiganghwal-tang. Methods : We induced the respiratory inflammation mouse model by papain treatment. Female BALB/C mice (8 weeks old) were divided into three groups as follows: saline control group, papain treatment group (vehicle), papain and Gumiganghwal-tang (200 mg/kg) treatment group (n=4). To verify the anti-inflammatory effect of Gumiganghwal-tang extracts, we measured the infiltration of inflammatory cells in bronchoalveolar lavage fluid (BALF) and nasal lavage fluid (NALF). Additionally, the efficacy of Gumiganghwal-tang extracts on Th2 cell population and alveolar macrophage in lung were analyzed by using flow cytometry. Results : Gumiganghwal-tang extracts administration decreased inflammatory cell infiltration in BALF and NALF, especially of eosinophils. Furthermore, interleukin-5 level was reduced in lung by drug administration. Interestingly, Gumiganghwal-tang extracts treatment also decreased the Th2 cell (CD4+ GATA3+ ) population and increased the alveolar macrophage (CD11b+ CD11c+ ) population in lung. Conclusions : Our findings indicate that Gumiganghwal-tang extracts have anti-inflammatory effects by mediating Th2 cell and alveolar macrophage cell activation.
