Objectives : Allium hookeri is a well-known traditional herbal remedy and its root used for treatment of inflammation and tumor. However, the mechanism of anti-inflammatory effect of Allium hookeri is still unknown. This study aims to examine the mechanism of anti-inflammatory effect of Allium hookeri on mouse macrophage cell line, RAW 264.7 cells. Methods : Anti-oxidant effect of water extract of Allium hookeri (WEAH) was measured by 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay. 3- (4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay was performed to determine the effect of WEAH on cell viability in RAW 264.7 cells. In addition, anti-inflammatory effect of WEAH was investigated in RAW 264.7 cells. Inflammation of RAW 264.7 cells induced by lipopolysarccharide (LPS) treatment and expression levels of inflammatory cytokine interleukin 1 β (IL-1β) and interleukin 6 (IL-6) gene were analyzed using quantitative reverse transcription PCR (qRT-PCR) analysis. Furthermore, the phosphorylation of inhibitor of nuclear factor kappa B (IκBα) after LPS treatment with WEAH-treated RAW 264.7 cells was confirmed by immunoblot analysis. Results : WEAH showed a strong anti-oxidant effect and no cytotoxicity to RAW 264.7 cells up to 2 mg/㎖ concentration. The LPS-induced mRNA expression levels of IL-1β and IL-6 were decreased by WEAH treatment. Furthermore, the LPS-induced phosphorylation of IκBα is attenuated by WEAH treatment. Conclusions : Through experimental demonstration of anti-oxidant and anti-inflammatory effects of WEAH, we suggest that Allium hookeri is a valuable material for prevention and treatment of various inflammatory diseases.
