In order to investigate the effect of CGT on atopic dermatitis, various anti-inflammatory factors were studied. In-vitro, inflammatory mediators, such as MTT and nitric oxide and ROS were detected after the addition of LPS with or without CGT in RAW 264.7 cells. In-vivo, in order to verify the effectiveness of CGT in atopic dermatitis animal model, its role in inflammation factors and histological changes were observed in NC/Nga mice. CGT showed cell viability of 100% or higher in all concentration in RAW 264.7 cells. CGT inhibited LPS-induced productions of inflammatory mediators nitric oxide and antioxidant activity reactive oxygen species production in RAW 264.7 cells. CGT treated group showed significant decrease in serum of the expression of IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ by 53%, 43% and 57% respectively. And CGT treated group showed decrease in serum of the expression of IgE by 56% respectively. Also, infiltration of adipocytes into skin was suppressed and the thickness of epidermis and dermis were relatively decreased in the CGT treated group. As a result, CGT has an anti-inflammatory effects in NC/Nga mouse. Thus, these results suggested a beneficial effect of CGT in treatment with Atopic dermatitis and inflammatory.
