초록
본 연구는 부채마 70% 에탄올 추출물(DR)이 RBL-2H3 마스트 세포에서 항원에 의한 세포활성의 영향과 BALB/c 쥐에서 dinitrofluorobenzene에 의해 유도된 마스트 세포-매개 알레르기 접촉성피부염에 미치는 영향을 조사했다. DNP-HSA 항원과 Anti-DNP IgE 항체에 의해 활성 된 RBL-2H3 세포에서 에탄올 추출물은 급성 항원반응 표지인 β-hexosaminidase 분비와 히스타민 등을 억제하였고, 후기 항원반응 표지인 IL-4와 TNF-α 생성을 억압하였다. DNFB-유도 접촉성 알러지성 피부염 동물 모델에서 에탄올 추출물 처리는 귀 부기를 감소시키고 혈청 히스타민과 IL-4 분비를 억제시켰으며, DR 처리는 피부염 유발 부분에서 마스트 세포 유입을 효과적으로 방지하였다. 이러한 결과로, 에탄올 추출물은 아토피 피부염과 같은 마스트 세포-매개 알러지성 질병의 치료제로 사용할 수 있을 것이다.
Abstract
This study was conducted to investigate the effect of 70% ethanol extract (DR) on the mast cell-mediated allergic contact dermatitis induced by dinitrofluorobenzene in BALB / c mice, which affects the cell activity by antigen in RBL-2H3 mast cells Respectively. The ethanol extracts of RBL-2H3 cells activated by DNP-HSA and anti-DNP IgE antibodies inhibited the secretion of β-hexosaminidase, histamine, and IL-4 and TNF-α Production was suppressed. In the DNFB-induced contact allergic dermatitis animal model, treatment with ethanol extract reduced ear swelling and inhibited serum histamine and IL-4 secretion, and DR treatment effectively prevented mast cell infiltration in dermatitis-induced areas. As a result, the ethanol extract may be used as a therapeutic agent for mast cell-mediated allergic diseases such as atopic dermatitis.
