Objectives The purpose of this study is to investigate the effect of YHJST on atopic dermatitis in an experiment using an NC/Nga mice induced by DNCB, which has histological and clinical similarities to the condition in humans. Methods To investigate the effect of YHJST on atopic dermatitis(AD), we evaluated atopic dermatitis-like skin lesions by clinical skin index and analyzed immunological parameters in peripheral blood mononuclear cells(PBMCs) and performed skin histology in ears and dorsal skin of NC/Nga ato-mouse. Results YHJST medicines decreased Serum level of IgE, IL-6, TNF-$\alpha$. Also total number of $CD69^+$, $CD3^+$ in PBMCs, absolute cell number of $CCR3^+CD3^+$, $CD11b^+Gr-1^+$ in Dorsal skin tissue, Serum IgG1, IgM, IgG2a and IgG2b decreased significantly. Furthermore YHJST is extremely effective to histological symptoms; dermal and epidermal thickening, hyperkeratosis and inflammatory cell infiltration and suppressed histologic infiltration of $CD4^+$ & $CCR3^+$ in ear and dorsal skin lesions significantly. YHJST decreased gene-expression of IL-6, TNF-$\alpha$, CCR3, Eotaxin mRNA than that of control group. Conclusions YHJST on atopic dermatitis to atopic dermatitis NC/Nga mouse induced DNCB was incredibly effective.
