초록
Objectives: The purpose of this study was to investigate the anti-inflammatory effects of aqueous extract from Picrasmae Lignum(PL). Methods: To evaluate the anti-inflammatory effects of PL extract, the productions of NO, PGE2 and expression of pro-inflammatory cytokine(IL-1b, IL-6 and TNF-a) were measured in LPS-induced RAW 264.7 cells. Furthermore Western blot analysis has been done to look into the inhibitory mechanisms such as MAPKs and NF-kB. Results: PL extract down-regulated LPS-induced NO, PGE2, IL-1b, IL-6 and TNF-a productions mainly through JNK and p38 MAPK pathway and NF-kB pathway. Conclusions: These results suggest that PL extract may be effective for the treatment of inflammatory diseases.
