PURPOSE : Euonymi Lignum Suberalatum (EL) is the stem fin of Euonymi alatus. In traditional Korean medicine, EL is used for treatment of uterine bleeding, metritis and static blood. Recently, many studies have reported several pharmacological effects of EL including anticancer, antimicrobial, antidiabetic activity, and anti-oxidative stress. However, the mechanisms underlying anti-inflammatory effects by the EL is not established. METHODS : To investigate anti-inflammatory effects of Euonymi Lignum Suberalatum Water (ELWE), Raw 264.7 cells were pre-treated with $10-300{\mu}g/mL$ of ELWE, and then exposed to $1{\mu}g/mL$ of LPS. Levels of NO, IL-6, $IL-1{\beta}$ and $TNF-{\alpha}$ were detected by ELISA kit. Expression of pro-inflammatory proteins were determined by immunoblot analysis. To evaluate the anti-inflammatory effect in vivo, rat paw edema volume, and expressions of COX-2 and iNOS proteins in carrageenan (CA)-induced rat paw edema model. RESULTS : NO production activated by LPS, was decreased by $30-300{\mu}g/mL$ of ELWE. Production of inflammatory mediators such as $TNF-{\alpha}$, ILs, $PGE_2$ were decreased by ELWE 100 and $300{\mu}g/mL$. In addition, ELWE reduced LPS-mediated iNOS and COX-2 expression. Moreover, ELWE increased $I-{\kappa}B{\alpha}$ expression in cytoplasm and decreased $NF-{\kappa}B$ expression in nucleus. In vivo study, ELWE reduced the increases of paw swelling, and expression of iNOS and COX-2 proteins in paw edema induced by CA injection. CONCLUSION : The results indicate that ELWE could inhibit the acute inflammatory response, via modulation of $NF-{\kappa}B$ activation. Furthermore, inhibition of rat paw edema induced by CA is considered as clear evidence that ELWE may be a useful source to treat acute inflammation.
