잣나무에 함유된 천연물은 무엇이 있는가? | 잣나무(Pinus koraiensis Siebold et Zucc)는 소나무과에 속하는 상록교목으로, Lee 등(2003)은 잣나무에 함유된 천연물로 5-hydroxy-7-methoxyflavone, chrysin, pinocembrin, galangin, pinosylvin, 3-hydroxy-5-methoxystilbene 등을 보고하였고, Bae등(2003)과 Cuyckens와 Claeys (2004)는 잣나무 잎의 성분으로는 gallic acid, protocatechuic acid, vanillic acid, syringic acid, p-coumaric acid, scopoletin, (+)-catechin 등의 물질을 분리 동정하였다. 또한 Kim 등(2010)은 잣나무 잎에 존재하는 항균물질이 astragalin과 juglanin임을 보고하였다. | |
macrophage가 염증을 일으키는 기전은 무엇인가? | 생체의 면역기구로 골수에서 생산되는 탐식세포인 macrophage는 체내에 들어온 이물질을 세포독성물질을 분비하여 이종세포나 암세포를 파괴하는 면역세포인데, 미량의 그람 음성균의 외막 구성성분인 lipopolysaccharide에 의해 활성화되어 cytokine, 활성산소, nitric oxide (NO) 등을 생산, 방출하게 된다(Oshima와 Bartsch 1994; Gross와 Wolin 1995; Kroncke 등, 1998).특히, 대식세포에서 lipopolysaccharide와 같은 자극에 의해 염증 반응의 전사인자인 nuclear factor-κB를 활성화시켜 inducible nitric oxide synthase (iNOS)와 cyclooxygenase-2 단백질을 발현시켜 과량의 NO와 prostaglandin E2를 생성하여 염증을 일으킨다(Stuehr 1999; So 등, 2004; Nirupama 등, 2005). 이때 interleukin-1β, IL-6 그리고 tumor necrosis factor와 같은 proinflammatory cytokine을 분비하여 염증반응에도 관여하게 된다(Naoko 등, 2005; Nirupama 등, 2005). | |
