Abstract

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.

본 실험에서는 CGT의 항염증과 관련한 다양한 실험을 실시하였다. In-vitro 실험에서 MTT, NO, ROS와 같은 염증 매개 물질 실험은 RAW 264.7 세포를 이용하여 실시하였다. In-vivo 실험은 아토피피부염 동물 모델인 NC/Nga 생쥐에서 항염증과 관련한 인자 및 조직학적 변화 등을 관찰하였다. CGT는 RAW 264.7 세포에서 100% 이상의 생존율을 나타냈으며, LPS를 이용한 NO와 ROS의 검사에서도 효과를 나타내었다. CGT 처치 그룹은 혈청 내 IL-$1{\beta}$와 IL-6, TNF-흰 에서 53%, 43%, 57%의 유의성 있는 감소를 나타내었고, IgE 역시 56%의 감소를 보였다. 또한, 피부에 지방세포의 침윤을 억제하고, 표피 및 진피의 두께 역시 감소하였다. 그 결과 CGT는 NC/Nga 생쥐에서 항염증에 효과를 나타내었다. 따라서 CGT는 아토피피부염과 염증 치료에 좋은 효과가 있다고 제안하는 바이다.
