비단벌레(Crysochroa fulgidissima) 에탄올추출물의 NO 증강 및 염증인자억제활성 = NO and Cytokine Production due to Crysochroa fulgidissima

국문 초록 (Abstract)

비단벌레(C. fulgidissima)는 동아시아에서 중풍을 치료하는 약으로 한국에서는 살충, 지양제로서 사용한 기록이 있다. 본 연구는 비단벌레의 에탄올 추출물의 내피세포에서의 산화질소(NO) 증강효과와 내피성 산화질소 합성효소(eNOS)의 양적 증가를 조사하였다. 그 결과 비단벌레 에탄올 추출물은 양성대조약물 sodium nitroprusside에 비해 65.9%의 NO 증강 효과를 가지는 것을 확인하였다. 또한 eNOS에 대해서도 농도 의존적으로 증가시킴을 확인하였다. 염증성부착인자인 ICAM-1과 VCAM-1 수치와 염증매개인자 프로스타글란딘 $E_2$를 조사하여 비단벌레 에탄올 추출물의 염증억제 기전을 조사한 결과, HUVEC 세포에서 농도 의존적으로 염증매개인자와 염증성부착인자의 감소를 확인하였다. 아울러 혈관성 내피성장인자(VEGF)의 낮은 수치를 HUVEC 세포에서 관찰할 수 있었다. 에탄올 추출물을 HPLC로 부분정제 후 GC-MS와 MALDI-TOF 분석을 통하여 일부 칸다리딘 성분 함유함을 확인하였다

다국어 초록 (Multilingual Abstract)

Crysochroa fulgidissima (Bidan-beole, Spanish fly) is traditionally used as a crude drug and insecticide in the East Asia and Korea, respectively. This study investigated the effect of ethanol extract of C. fulgidissima on the NO production activity. The C. fulgidissima extract was a potent inducer of NO production in CPAE cells and a stimulator of endothelial nitric oxide synthase in a dose-dependent manner. This study also evaluated the anti-inflammatory activity of this extract by determining the level of ICAM-1, VCAM-1, and prostaglandin $E_2$ from HUVEC cells. Although C. fulgidissima extract was a potent inducer of NO production in the CPAE cells, it showed weak inhibitory effects on vascular endothelial growth factor (VEGF) production in HUVEC cells. HPLC and GC-MS analysis of the ethanol extract of C. fulgidissima revealed the presence of cantharidin.
