염증 및 통증의 기전에 관해 보고된 바는 어떠한가? | , 2011). 현재까지 알려진 염증 및 통증의 기전은 세포손상으로 인한 히스타민 (histamine) 및 키닌 (kinin) 등의 방출로 혈관확장, 모세혈관 투과성 증가 및 염증부위로 대식세포의 집결, 염증부위에 혈류량 증가, 부종, 면역세포와 항체의 이동, 통증 및 발열 등의 현상이 일어난다고 보고되고 있다 (Lee et al., 2011; Carey et al. | |
퇴행성관절염의 원인은 무엇인가? | 퇴행성관절염 (degenerative arthritis, degenerative joint disease)이란 골관절염 (osteoarthritis)이라고도 하며 외상, 관절 기형, 유전적 요소, 비만, 생활습관으로 발병하는 경우도 있으나 환자의 대다수는 노화로 인해 관절을 보호하는 연골의 퇴행성 손상으로 염증 및 통증을 유발하는 경우이다 (Chang et al., 2005; Kraan and Berg, 2008; Yeom, 2013). | |
본 연구에서 NO의 생성을 억제한 실험 결과가 iNOS의 발현 저해로부터 야기되었다고 추측한 근거는 무엇인가? | 7 세포에 처리하였을 때 NO 생성이 약 44% 감소되었다고 보고하였다. Korhonen 등 (2005)에 의하면 pro-inflammatory cytokine이나 염증성 자극에 의해 iNOS (inducible Nitric Oxide Synthase)의 발현이 증가되면 NO가 과량 분비되어 정상세포를 손상시키고 염증에 악화시킨다. CME 처리가 LPS로 유도된 RAW 264. |
