초록
Objective : The present study was examined to evaluate the effects of Ecliptae Herba on the production of inflammatory mediators in vivo and in vitro. Methods : In cell viability, all three doses of Ecliptae Herba extract (25, 50 and 100 μg/㎖) had no significant cytotoxicity during the experimental period. The increases of NO production and iNOS expression were detected in LPS-activated cells compared to control, but these increases were dose-dependently attenuated by pre-treatment with Ecliptae Herba extract. Results : 1. LPS plays a pivotal roles in inducing to the massive production of pro-inflammatory cytokines such as TNF-α, IL-1β and IL-6 in macrophages. 2. Ecliptae Herba extract reduced the elevated production of cytokines by LPS. 3. Ecliptae Herba extract reduced PGE2 levels in a dose-dependent manner as a consequence of inhibition of COX-2 activity. 4. Ecliptae Herba extract significantly reduced the nuclear translocation of NF-κB induced by LPS. 5. In histopathological study, Ecliptae Herba effectively inhibited the increases of hind paw edema, skin thicknesses and inflammatory cell infiltrations induced by carrageenan treatment. Conclusions : These results provide evidences that therapeutic effect of Ecliptae Herba on the acute inflammation is partly due to the reduction of some of inflammatory factors by inhibiting iNOS and COX-2through the suppression of NF-κB.
