Recently Atopic Dermatitis(AD) is increasing along with allergic disease. At present, there is no infallible cure for AD. Then AD patients undergo great suffering. This study is carried out to see whether or not the administering Danggwieumja(DG) along with Samhwangseje-gamibang(SG} as a medicine for external aplication, is effective in treating atopic dermatitis. To examine the effectiveness of the above prescription, the author made an observation of diverse immune responses. through the model of NC/Nga atopic mice. Results provided evidence that the DG administration along with SG can be used as a treatment means to atopic dermatitis. The results are as follows: The extent of Clinical skin severities in 13 and 16 week old NC/Nga mice treated with DG and SG, were reduced by 50.9%, 53.9% respectively, compared to the control NC/Nga mice with no drug treatment. IgE, IL-4, IL-5, IL-6, IgM and IgG1 levels in the serum of the NC/Nga mice treated with DG and SG were significantly decreased compared to those of the untreated control mice. In contrary, to the $IFN-{\gamma}$ level, significantly increased. The spleen weight of the NC/Nga mice treated with DG and SG significantly decreased compared to those of the untreated control mice. CCR3 gene expression in the skin tissue of NC/Nga mice treated with DG and SG were highly decreased, and the IL-6 expression significantly decreased, and the $IFN-{\gamma}$ gene expression increased compared to those of the untreated control mice. Histological observation of the ear and dorsal skin tissue of the NC/Nga mice treated with DG and SG, showed that the extents of inflammation and infiltrated immune cells in the epidermal tissue and dermis, were highly reduced compared to those of the untreated control mice. In the model inducing COX-2 activity in RAW 264.7 cell, the denser DG became, the more COX-2 activity was inhibited, compared to those of the untreated control group. $IL-1{\beta}$, and $TNF-{\alpha}$, IL-6 gene expression in RAW 264.7 cell with DG, significantly decreased, compared to those of the untreated control group. According to the assessment of cell toxicity in L929 cell, the rate of cell multiplication increased by 3% in consistency to 100ppm of DG compared to the untreated control group and in more than the 200 ppm consistency, cell toxicity was occurred.

The purpose of this study is to examine closely effect that Onchung-eum(OC) and Samhwangseze-gamibang(SG) used to atopic dermatitis disease patient get in atopy eruption control experimentally. Atopic dermatitis(AD) of molecular mechanism underlying it's effectiveness is unknown. We analyzed the expression the clinical severities in 13 and 16 weeks old NC/Nga mice, and the spleen weight of OC with SG treated NC/Nga mice, and mRNA expression levels of IL-4, IL-5, and CCR3 in the skin tissues of OC with SG treated NC/Nga mice, and IL-1${\beta}$, TNF-${\alpha}$, IL-6 express of gene, and Histological observation of the ear and skin tissues, and than IgE, IL-4, IL-5, IL-6, IgM, IgGl levels in the serum of OC with SG treated NC/Nga mouse group compared to the untreated control mouse group. Also, We examined cell toxicity that of OC is safety the strength of 10, 50, 100ppm and inflammatory RAW 264.7 in the serum of OC. Thus in these present study diverse immune responses in terms of chemical mediators related to AD were investigated using an atopic mouse model NC/Nga after OC along with 5G. At the result that OC along with SG treat is can effective use for the treatment of atopic dermatitis(AD).
