摘要：
The present invention discloses a composition for ameliorating chronic obstructive pulmonary disease (COPD) by using an extract of Reynoutria elliptica or the like. A food composition for reinforcing a respiratory function and ameliorating a respiratory disease comprises an extract of Reynoutria elliptica as an active ingredient. The extract of Reynoutria elliptica or the like has activities of inhibiting Netosis activation of Neutrophil extracellular traps induced by phorbol myristate acetate (PMA), inhibiting expression of IL-8, i.e., inflammatory cytokines caused by CSE of NCI-H292 cells, i.e., a bronchial epithelial cell line, and inhibiting expression of MIP-2, i.e., inflammatory cytokines even in MH-S cells, i.e., alveolar macrophages activated by CES and lipopolysaccharide (LPS). Further, the extract of Reynoutria elliptica has an activities of inhibiting infiltration of immune cells within BALF and inhibiting secretion of inflammatory cytokines and chemokines in a respiratory disease mouse model induced by CSE and PPE.COPYRIGHT KIPO 2020본 발명은 호장근 추출물 등을 이용한 만성폐쇄성폐질환 개선용 조성물을 개시한다. 호장근 추출물 등은 PMA(phorbol myristate acetate)에 의해 유도된 호중구 세포외 트랩(Neutrophil extracellular traps)의 네토시스(Netosis) 활성화를 억제하고, 기관지 상피세포주인 NCI-H292 세포의 CSE에 의한 염증성 사이토카인인 IL-8의 발현을 억제하며, 또한 CES와 LPS(lipopolysaccharide) 의해 활성된 폐포 대식세포인 MH-S 세포에서도 염증성 사이토카인인 MIP-2의 발현을 억제하는 활성을 가진다. 또한, 호장근 추출물은 CSE와 PPE로 유도된 호흡기 질환 마우스 모델에서 BALF 내 면역세포의 침윤을 억제하며 염증성 사이토카인과 케모카인 분비를 억제하는 활성을 가진다.
