This study aimed to evaluate the anti-asthmatic effects of Samjajihwang-tang (SJT) using OVA-induced asthmatic mice model. Asthmatic mice model was conducted by repeated challenge of OVA using C57BL/6 mice. Each group was treated with distilled water, SJT (400 mg/kg and 200 mg/kg) extract or cyclosporin A (10 mg/kg) for the later 8 weeks, Penh (plethysmography and enhanced pause), immune cells subpopulation, eotaxin, IL-5, TNF-${\alpha}$, Anti-OVA-lgE in BALF (bronchoalveolar lavage), and lung tissue was analyzed, No cytotoxicity of SJT was shown on hFCs (human fibroblast cells). Administration of SJT significantly decreased Penh levels comparing to control group. SJT treatment significantly ameliorated the increase of total cells number and eosinophil including of immune cell subpopulation of $CD3^+/CD69^+$, $CCR3^+$, $B220^+/CD22^+$, $B220^+/CD45^+$, and $B220^+/lgE^+$ cells in BALF comparing to control group. Eotaxin, IL-5, TNF-${\alpha}$, and Anti-OVA-lgE level in BALF were significantly decreased by SJT treatment too. Histopathological finding verified the improvement of infiltration of inflammatory cells and collagen tissue in the SJT groups comparing to control group. These results strongly suggest that SJT would be a effective candidate for herbal-originated anti-asthmatic drug. However, this drug should be further studied for characterization of the accurate action and underlying mechanisms using variant disease model in the future.
