This study aimed at examining the anti-inflammatory effects of Scutellariae Radix & Lonicerae Caulis water extract(SC). RAW 264.7 mouse macrophage cells were treated with $25{\sim}200{\mu}g/m{\ell}$ SC for 24 hours. Cell viability was then measured using MTT assays. The nitric oxide(NO) production and the creation of several cytokines in LPS-stimulated RAW 264.7 cells were investigated. SC inhibited significantly increasing the production of NO in LPS-induced RAW 264.7 cell at the density of 25, 50 and $200{\mu}g/m{\ell}$. SC inhibited significantly the TNF-${\alpha}$ of the RAW 264.7 cell induced by LPS at the density of $50{\mu}g/m{\ell}$. SC inhibited significantly the MIP-$1{\alpha}$ of the RAW 264.7 cell induced by LPS at the density of 25, 50 and $100{\mu}g/m{\ell}$. SC inhibited significantly the MIP-$1{\beta}$, MIP-2 at the density of 50, $100{\mu}g/m{\ell}$ in the RAW 264.7 cell increased by LPS, respectively. SC did not affect the production levels of VEGF in RAW 264.7 cell. As a result, SC significantly inhibited the inductions of MIP-$1{\alpha}$, MIP-$1{\beta}$, MIP-2 and NO in LPS-induced RAW 264.7 cell without causing the toxicity. These results signify that SC has anti-inflammatory effects on controlling the over inflammatory reaction on the RAW 264.7 cell.

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.

Purpose : The Purpose of this research was to investigate the effects of Cheongyeolhawlhyeoltanggagyehyeoldeung (CYHHT) on anti-inflammatory effects. Methods : As for the parameters of inflammation, levels of several inflammatory cytokines and chemical mediators were determined in mouse lung fibroblast cells(mLFC) and RAW264.7 cells. Also, changes in pathological features by drug treatment were investigated in the in vivo edema-induced rats by carrageenin /arachidonic acid or in the colitis-induced mice by DSS treatment. Results : The cytotoxicity of CYHHT on mLFC and RAW264.7 cells was not observed at 100, 50, 10, and $1{\mu}g/ml$ of CYHHT treatments. $IL-1{\beta}$, IL-6 and NOS-IImRNA expression of RAW264.7 cells was inhibited by CYHHT treatments in a dose-dependent manner. CYHHT treatment of RAW264.7 cells inhibited $TNF-{\alpha}$ and COX-2 mRNA expression. CYHHT treatment of RAW264.7 cells significantly inhibited IL-6 and NO production. CYHHT treatment of RAW264.7 cells inhibited ROS production. CYHHT inhibited rat's paw edema induced by carrageenin or arachidonate treatment in all concentrations examined. The body weight and colon length of colitis-induced mice were recovered to a normal level by DSS treatment. Clinical disease levels were significantly improved compared to the control animals. CYHHT treatment of colitis-induced mice significantly increased hematological values such as WBC and RBC counts, Hgb and HCT levels, but decreased PLT values. CYHHT treatment of colitis-induced mice decreased IL-6 and $TNF-{\alpha}$ production significantly CYHHT treatment of colitis-induced mice significantly increased CD3+(T) cell counts. In contrast, CYHHT treatment decreased CD19+ B cell counts and CD3+/CD69+ significantly, and also decreased B/T ratio (%) though not significant. Conclusion : These results indicated that CYHHT could be used for treating diverse female diseases caused by the inflammation.

본 연구는 침출차 원료로 레드비트를 활용하기 위해서 세포독성, 항염증 및 항산화 등의 활성을 조사하고자 설계되었다. 항산화 효능은 DPPH 및 ABTS 라디컬 소거 활성을 분석하여 평가하였다. RAW 264.7 세포를 통해 MTT 분석으로 세포 생존율을 평가하고 LPS로 유도하여 활성산소종과 염증매개체(일산화질소, TNF-α, IL-6 등)의 생성량을 확인하였다. 그 결과, DPPH 및 ABTS 라디컬 소거활성은 농도 의존적으로 증가하였으며, 모든 농도에서 세포독성이 없음을 확인하였다. 또한, LPS로 유도한 RAW 264.7 세포에서 활성산소종(ROS)과 일산화질소(NO), IL-6, TNF-α 생성량을 유의적으로 감소시켰다. 따라서 이러한 결과는 레드비트가 안전한 항산화 및 항염증 효과를 가진 침출차의 원료로서 높은 잠재력을 가지고 있음을 시사한다.
