  • Objectives : Illicium verum Hook. f. has been known to possess antimicrobial, antioxidant, antifungal, anti-inflammatory, insecticidal, analgesic, sedative, convulsive activities, it has been rarely conducted to evaluate the immuno-biological activity. The present study was examined to evaluate the anti-inflammatory effects of the Illicium verum Hook. f. water extracts (IVE) in vivo and in vitro. Methods : Cell viability was measured by MTT assay. The relative levels of NO were measured with Griess reagent. iNOS, COX-2, $NF-{\kappa}B$ and target proteins were detected by immunoblot analysis, and levels of cytokines were analyzed by ELISA kit. Anti-edema effect was determined in the carrageenan (CA)-induced paw edema model in rats. Results : All dosages of IVE used in MTT assay had no significant cytotoxicity. The increases of NO production and iNOS expression were detected in LPS-treated cells compared with control. However, these increases were attenuated by treatment with IVE. Also, IVE reduced the elevated production of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 by LPS. IVE inhibited the $p-I{\kappa}B$ and translocation of $NF-{\kappa}B$ to nuclear. Furthermore, IVE significantly inhibited the increases of hind paw swelling, skin thicknesses and inflammatory cell infiltrations induced by CA injection. Therefore, IVE will be favorably inhibited the acute edematous inflammations. Conclusion : These results provide evidences that anti-inflammatory effect of IVE is partly due to the reduction of some inflammatory mediators by suppression of $NF-{\kappa}B$ pathway.
