사간 물 추출물의 항염증 효과

초록

The purpose of this study was to investigate the anti-inflammatory effects of aqueous extract from Belamcanda chinensis (BC) on the RAW 264.7 cells. To evaluate the anti-inflammatory effects of BC, we examined the cytokine productions including nitric oxide (NO), interleukin (IL)-1b, IL-6 and tumor necrosis factor-a (TNF-a) in lipopolysaccharide (LPS)-induced RAW 264.7 cells and also inhibitory mechanisms such as mitogen-activated protein kinases (MAPKs) and nuclear factor kappa B (NF-kB) using Western blot. BC inhibited LPS-induced production of NO, IL-6 and TNF-a but not of IL-1b in RAW 264.7 cells. BC respectively inhibited the activation of MAPKs such as c-Jun NH2-terminal kinase (JNK) and p38 but not of extracelluar signal-regulated kinase (ERK 1/2) and NF-kB in the LPS-stimulated RAW 264.7 cells. Taken together, Our results showed that BC down-regulated LPS-induced NO, IL-6 and TNF-a productions mainly through JNK and p38 MAPK pathway.
