Objectives : HRHDT has been known as a useful prescription with antibiotic, anti-inflammatory, antioxidative and immunosuppressive activity. To evaluate anti-atopic dermatitis effect of HRHDT, we treated HRHDT in NC/Nga mice model skin induced contact hypersensitivity. Methods : Contact hypersensitivity, a local inflammatory response of skin, was induced by spreading the back skin of NC/Nga mice with 0.4${\sim}$1% DNCB. HRHDT was prepared by dissolving 3% HRHDT in solution and treated 3 weeks on the back skin. Results : HRHDT significantly reduced TEWL and erythema by 0.4${\sim}$1% of DNCB treatment compared to control group. HRHDT also reduced IgE on serum obtained from blood of DNCB-treated mice. Conclusions : These results showed that HRHDT could be used as a pharmaceutical material with anti-atopic dermatitis effect by reducing IgE in contact, hypersensitivity atopic dermatitis NC/Nga mice model by DNCB.
