  • Although inflammatory mediators such as nitric oxide(NO) and pro-inflammatory cytokines are involved in host defense mechanism, these overproduction contributes to the pathogenesis of several diseases such as otitis media, hearing loss, periodontitis, bacterial sepsis, rheumatoid arthritis, chronic inflammation and autoimmune diseases. We investigate the anti-inflammatory effects of water extract from Ji-Pae-San(JPSWE) fomulated with Angelica dahurica plus Fritillaria Verticillata, Angelica dahurica(ADWE), and Fritillaria Verticillata(FUVE) in vitro and in vivo. Each extract inhibited the production of inflammatory mediators(NO, $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, and prostaglandin $E_2$) and the expression of inducible NO synthase(iNOS) and cyclooxygenase-2(COX-2) in lipopolysaccharide(LPS)-stimulated RAW 264.7 macrophages in a dose-dependent manner. These inhibitory effects were synergistically increased by their combination. JPSWE also inhibited $TNF-{\alpha}$, $IL-1{\beta}$, IL-6. and $PGE_2$ production as well as COX activity in LPS-stimulated mice. Moreover, JPSWE significantly suppressed death by LPS-septic shock in mice(survival rate: 100%). These results suggest that Ji-Pae-San may be useful for therapeutic drugs against inflammatory immune diseases, probably by suppressing the production of inflammatory mediators.

  • Antiallergic and antipsoriatic effects of korean Red Ginseng (KRG, steamed root of panax ginseng C.A. Meyer, Family Araliaceae) were measured. Orally administered KRG water extract potently inhibited passive cutaneous anaphylaxis (PCA). KRG water extract also showed the potent inhibition in oxazolone-induced mouse dermatitis, and suppressed mouse ear swelling by $39\%$ at 16 days at a dose of $0.1\%$. KRG water extract reduced the levels of mRNA of cyclooxygenase (COX)-2, $IL-1\beta$, $TNF-\alpha$ and $INF-\gamma$ increased in oxazolone-applied mouse ears, however, did not inhibit that of IL-4. KRG water extract also inhibited iNOS and COX-2 mRNA expression level of RAW264.7 cell induced by lipopolysaccharide. Based on these findings, we suggest that KRG can improve atopic and contact dermatitis by the regulation of $ IL-1\beta$ and $TNF-\alpha$ produced by macrophage cells and $interferon-\gamma$ produced by Th1 cells.

  • Objectives : In this study, we investigated the anti-inflammatory and anti-oxidative effects of MOK, a pharmacopuncture medicine, in lipopolysaccharide (LPS)-stimulated mouse peritoneal macrophages. Methods : Peritoneal macrophages were isolated from ICR mice. Primary macrophages were treated with MOK extract (1.25, 2.5, 5, 10, and 20 mg/ml) for 30 min and then stimulated with LPS ($1{\mu}g/ml$) for the indicated times. Cytotoxicity was measured using MTT and LDH assays. Nitric oxide (NO) production in culture supernatants was measured using the Griess assay. The mRNA expression of iNOS, COX-2, proinflammatory cytokines (TNF-${\alpha}$, IL-$1{\beta}$, and IL-6) and antioxidant enzymes (HO-1 and MnSOD) was measured by RT-PCR. Results : Treatment with MOK extract (2.5, 5, and 10 mg/ml) significantly decreased LPS-induced NO production in peritoneal macrophages through inhibition of iNOS expression. The expression of COX-2, TNF-${\alpha}$, IL-$1{\beta}$, and IL-6 mRNA was also decreased in LPS-stimulated macrophages upon treatment with MOK extract. MOK treatment also increased the expression of HO-1 and MnSOD mRNA in macrophages. Conclusion : These results indicate that MOK exerts anti-inflammatory and antioxidant effects by regulating the transcription levels of inflammatory mediators and antioxidant proteins in activated macrophages.

  • This study was designed to investigate the inhibitory effects of Perilla frutescens (L.) Britton var. frutescens extract on the production of inflammation-related mediators (NO, ROS, NF-${\kappa}B$, iNOS and COX-2) and pro-inflammatory cytokines (TNF-${\alpha}$, IL-$1{\beta}$, IL-6) in lipopolysaccharide-stimulated RAW 264.7 macrophages. Perilla frutescents (L.) Britton var. frutescens was air-dried and extracted with ethanol. The extract dose-dependently decreased the generation of intracellular reactive oxygen species and dose-dependently increased antioxidant enzyme activities, such as superoxide dismutase, catalase and glutathione peroxidase in lipopolysaccharide stimulated RAW 264.7 macrophages. Also, Perilla frutescens (L.) Britton var. frutescens extract suppressed NO production in lipopolysaccharide-stimulated RAW 264.7 cells. The expressions of pro-inflammatory cytokines (TNF-${\alpha}$, IL-$1{\beta}$ and IL-6), NF-${\kappa}B$, iNOS and COX-2 were inhibited by the treatment with the extract. Thus, this study shows the Perilla frutescens (L.) Britton var. frutescens extract could be useful for inhibition of the inflammatory process.

  • Rheumatoid arthritis (RA) is an autoimmune/inflammatory disorder with a complex genetic component. RA is characterized by chronic inflammation of the synovial membrane in the joint, which leads to the progressive destruction of articular cartilage, ligament and bone. Several cytokines such as tumor necrosis $factor-{\alpha}\;TNF-{\alpha}\;and\;interleukin-1{\beta}\;(IL-1{\beta})$ and interleukin-6 (IL-6) have been implicated in the pathological mechanisms of synovial tissue proliferation, joint destruction and programmed cell death in rheumatoid joint. Genome wide screening of subjects suffering from autoimmune diseases especially arthritis revealed linkage to inflammatory molecules like $TNF-{\alpha},\;IL-1{\beta}$ and IL-6, inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), nuclear factor-kappaB $(NF-{\kappa}B)$ and human leucocyte antigen/major histocompatibility complex (HLA/MHC) locus. The status of the pharmacological mechanism of herbal drugs in the light of genome wide screening results has been discussed to reinforce the therapeutic potential and the pharmacological basis of the herbal drugs.

  • This study was designed to investigate the anti-inflammatory effect of oyster shell extract on the production of pro-inflammatory factors [NO, reactive oxygen species (ROS), nuclear factor-kappa B (NF-${\kappa}B$), inducible nitric oxide synthase (iNOS) and cycloxygenase-2 (COX-2)] and pro-inflammatory cytokines [Interleukin-$1{\beta}$ (IL-$1{\beta}$), Interleukin-6 (IL-6) and TNF-${\alpha}$] in the lipopolysaccharide (LPS)-stimulated Raw 264.7 cells. Cell viability, as measured by the MTT assay, showed that oyster shell extract had no significant cytotoxicity in Raw 264.7 cells. The treatment with oyster shell extract decreased the generation of intracellular reactive oxygen species dose dependently and increased antioxidant enzyme activities, such as SOD, catalase, GSH-px in LPS-stimulated macrophage cells. Oyster shell extract significantly suppressed the production of NO and also decreased the expressions of iNOS, COX-2 and NF-${\kappa}B$. Additionally, oyster shell extract significantly inhibited the production of IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ in LPS-stimulated Raw 264.7 cells. Thus, these results showed that the oyster shell extract had an anti-inflammatory effect on LPS-stimulated Raw 264.7 cells.

  • Objectives This study was designed to investigate the anti-inflammatory effect of extracts from Ligustrum obtusifolium S. fruits(LOF) in RAW 264.7 Macrophages stimulated with lipopolysaccharide(LPS). Methods We examined productions of nitric oxide(NO), reactive oxygen species(ROS), inducible isoforms of NO synthase(iNOS), cyclooxygenase-2(COX-2) to investigate the anti-inflammatory effect of LOF extracts. In addition, we measured generation of pro-inflammatory cytokines(TNF-${\alpha}$, IL-6). Results Cell viability showed that LOF extracts had no cytotoxicity in Raw 264.7 cells. The treatment with LOF extracts significantly decreased the generation of NO and pro-inflammatory cytokines(TNF-${\alpha}$, IL-6) in LPS-stimulated macrophage cells. Furthermore LOF extracts inhibited intracellular ROS generation dose dependently and reduced the expression of iNOS, COX-2 proteins. Conclusions These results showed that the LOF extracts had an anti-inflammatory effect on LPS-stimulated Raw 264.7 cells. These findings provide scientific support for the use of this Ligustrum obtusifolium S. for inflammatory-related diseases.
