  • Objectives The object of this study was to assess the effect of Gyejibokryunghwan (GBH) on anti-oxidant and anti-inflammatory activities in RAW 264.7 cells and on factors associated with fracture union in tibia-fractured rats. Methods The 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activity was measured to assess anti-oxidant activity. The production of nitric oxide (NO), interleukin-6 (IL-6), interleukin-$1{\beta}$ ($IL-1{\beta}$) and tumor necrosis factor-${\alpha}$ ($TNF-{\alpha}$) in the RAW 264.7 cells were measured to assess anti-inflammatory activity. The production of osteocalcin, calcitonin, carboxy-terminal telepeptides of type II collagen (CTXII), transforming growth factor-${\beta}$ ($TGF-{\beta}$), bone morphogenetic protein-2 (BMP-2) in serum of tibia-fractured rats were measured to assess the effects of fracture union. X-rays were taken every two weeks from 0 to 4th week to assess fracture union effect. Results DPPH radical scavenging activity of GBH was increased according to concentration of GBH in RAW 264.7 cell. NO, prostaglandin $E_2$ ($PGE_2$), IL-6, $IL-1{\beta}$ and $TNF-{\alpha}$ were significantly decreased, indicating anti-inflammatory effect. Osteocalcin, calcitonin, $TGF-{\beta}$ were significantly increased in the experimental groups. CTXII was significantly decreased in the experimental groups. BMP-2 was not significantly changed in the experimental groups. The X-ray showed that the experimental group has better healing effects on tibia-fractured rats than control group. Conclusions From above result, GBH has an effect on anti-oxidant, anti-inflammatory activities in RAW 264.7 cells. GBH showed significant results in factors related with fracture union and radiologic examination. In conclusion, GBH can help fracture union and it well be expected to be used actively in clinics.

  • Purpose: This study was performed to evaluate the anti-inflammatory effect of Eungapbang extract (EGB). Methods: To evaluate the anti-inflammatory effects of EGB, we nourished RAW 264.7 cell lines in the laboratory dish. Next, inflammatory cytokine concentrations were analyzed. Then, sera were prepared from blood after lipopolysaccharide (LPS) injection in chemically induced mouse models of intestinal inflammation, and Interleukin-1${\beta}$ (IL-1${\beta}$), interleukin-6 (IL-6) and tumour necrosis factor alpha (TNF-${\alpha}$) were measured using ELISA kits. Results: 1. EGB significantly suppressed the expression levels of IL-1${\beta}$ and NOS-II genes at 100, 50 and 10 ${\mu}g/m{\ell}$ concentrations, and IL-6, TNF-${\alpha}$ and COX-2 mRNAs at 100 and 50 ${\mu}g/m{\ell}$ concentrations. 2. EGB significantly reduced the production level of IL-1${\beta}$ and TNF-${\alpha}$ at 100${\mu}g/m{\ell}$ concentrations, and IL-6 at 100 and 50 ${\mu}g/m{\ell}$ concentrations. 3. EGB significantly decreased the production level of IL-1${\beta}$ and IL-6 in sera of acute inflammation induced mice. 4. EGB could suppress the expression level of IL-1${\beta}$ and IL-6 mRNA in spleen tissues in acute inflammation induced mice. Conclusion: On the basis of the above results, it is confirmed that the anti-inflammatory effects of EGB were recognized. Therefore, EGB is recommended as promising therapy for treatment of such ailments as pelvic inflammatory disease.

  • 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.

  • Aim: Historically, mineral compound herbal medicines have long been used in treatments of immune-related diseases in Korea, China and other Asian countries. In this study, we investigated the anti-inflammatory effect of egg white combined with chalcanthite (IS4) on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Methods: RAW 264.7 cells cultured with LPS and various concentrations of IS4 were analyzed to determine the production of pro-inflammatory cytokines and mediators by using enzyme-linked immune sorbent assays (ELISAs). Results: IS4 concentration inhibited the production of interleukin-1beta (IL-$1{\beta}$), interleukin-6 (IL-6), and granulocyte-macrophage colony-stimulating factor (GM-CSF) induced by LPS. IS4 at high concentrations (25 and 50 ${\mu}g/ml$) inhibited, in concentration-dependent manner, the expression of tumor necrosis factor-alpha (TNF-${\alpha}$) stimulated by LPS. Conclusion: IS4 has shown an anti-inflammatory effect in RAW 264.7 cells.

  • Chronic inflammation has been known to have a close relationship with several diseases including periodontitis, colitis, hepatitis and arthritis. Recently anti-inflammatory agents have been developed from marine natural resources. In this study, Ecklonia cava (EC) was found to have anti-inflammatory effect. Ethanolic extract of EC belonging to brown algae exhibited an excellent inhibitory effect on the production of inflammatory mediators such as tumor necrosis factor-${\alpha}$, interleukin-$1{\beta}$, interleukin-6 and prostaglandin $E_2$ by RA W264.7 cells. Furthermore, in reporter gene assay and western blot analysis, EC extract exerted anti-inflammatory effect via inactivation of NF-${\kappa}B$ transcription factor that regulates the expression of these inflammatory mediators in macrophages. In addition, EC extract inhibited the activity of matrix metalloproteinase that play an important role in chronic inflammation. These results suggest that EC extract may provide a pharmaceutical potential in inhibiting chronic inflammation.

  • Objectives Bogol-tang has clinically been used to protect joint cartilage and to treat osteoarthritis. Our objective was to study the protective effect of Bogol-tang extract (BGT) in functional impairment, behavioral disorders, cartilage loss and pathological changes in a monoiodoacetate (MIA)-induced murine osteoarthritis (OA) model and interleukin (IL)-$1{\beta}$ -treated primary rat chondrocytes. Methods Mouse knee joints were injected with MIA, a chemical that inhibits glycolysis and causes joint inflammation and matrix loss. MIA-OA induced mice orally administered BGT or acetaminophen (AAP) for 18 days by daily. Primary rat chondrocytes were pretreated with BGT or dexamethasone (DEX) and followed by co-incubation with IL-$1{\beta}$ (10 ng/mL). Results In MIA-OA mice model, BGT led to delayed response on hot plate analysis, and suppressed the cartilage loss and damages in joint tissues. BGT suppressed the elevated levels of inflammatory mediators, nitrite and $PGE_2$, the gene expression of matrix degrading enzymes, and extracellular-signal-regulated kinases 1/2 and c-JunN-terminal kinase phosphorylation in IL-$1{\beta}$-treated primary rat chondrocytes. Conclusions Our results suggest that BGT improve the knee joint function and delay the cartilage damages by anti-nociceptive, anti-inflammatory and ant-catabolic effects, which indicate BGT could be a potential candidate for osteoarthritis treatment.

  • Background: Korean Red Ginseng extracts (RGE) have been suggested as effective immune modulators, and we reported that ginsenosides possess anti-inflammasome properties. However, the properties of nonsaponin components of RGE have not been well studied. Methods: To assess the roles of nonsaponin fractions (NS) in NLRP3 inflammasome activation, we treated murine macrophages with or without first or second inflammasome activation signals with RGE, NS, or saponin fractions (SF). The first signal was nuclear factor kappa-light-chain-enhancer of activated B cells (NF-${\kappa}B$)-mediated transcription of pro-interleukin (IL)-$1{\beta}$ and NLRP3 while the second signal triggered assembly of inflammasome components, leading to IL-$1{\beta}$ maturation. In addition, we examined the role of NS in IL-6 production and IL-$1{\beta}$ maturation in mice. Results: NS induced IL-$1{\beta}$ and NLRP3 transcription via toll-like receptor 4 signaling, whereas SF blocked expression. During the second signal, SF attenuated NLRP3 inflammasome activation while NS did not. Further, NS-injected mice presented increased IL-$1{\beta}$ maturation and IL-6 production. Conclusion: SF and NS of RGE play differential roles in the NLRP3 inflammasome activation. Hence, RGE can be suggested as an NLRP3 inflammasome modulator.

  • To investigate the anti-inflammatory effect of Ephedrae Herba in vivo and in vitro acute inflammation was induced by lipopolysaccharide (LPS) shock in rats fed Ephedrae Herba extracts and inflammatory cytokine concentrations were examined. In addition, the effect of Ephedrae Herba extracts on the production of inflammatory cytokines was examined in LPS-stimulated Raw 264.7 cells. In an in vivo experiment, plasma interleukin-$1{\beta}$ (IL-$1{\beta}$), interleukin-6 (IL-6), interleukin-10 (IL-10) and tumor necrosis factor-$\alpha$ (TNF-$\alpha$) concentrations were increased at 2 h and reached to maximal levels at 5 h after LPS treatment in all groups. Compared with control group, plasma IL-$1{\beta}$, IL-6, and TNF-$\alpha$ levels were lowered at 5 h after LPS treatment, but plasma IL-10 level was higher in at 2 and 5 h after LPS treatment in Ephedrae Herba extract group. In an in vitro experiment using Raw 264.7 macrophages, IL-$1{\beta}$, IL-6 and TNF-$\alpha$ concentrations in the Ephedrae Herba extract group were lower than those in control group. Compared with control group, IL-10 concentration appeared to be higher in the Ephedrae Herba extract group, but this trend was not significant. In conclusion, these results suggested that functional compound (s) in Ephedrae Herba extract may play a role in alleviating inflammatory response.

  • The object of this trial was to investigate the effect of dietary ${\beta}$-1,3/1,6-glucan supplementation on the performance and immunological response of broiler chickens. Two hundred and forty 1-day old male broilers ($39{\pm}1g$) were separated into six treatments which were given six different feeds containing 0 (control), 25, 50, 75, 100 and 125 mg/kg dietary ${\beta}$-1,3/1,6-glucan supplementation. On days 21 and 42, body weight gain, feed consumption and feed conversation rate were recorded as measures of growth performance. The levels of key cytokines in the immuno-regulating pathway: interleukin-1 (IL-1), interleukin-2 (IL-2), interferon $\gamma$(IFN-$\gamma$, tumor necrosis factor $\alpha$(TNF-$\alpha$, and the concentrations of signal molecules: peripheral blood plasma globulin, serum Immunoglobulin G (IgG) and intestinal secretary Immunoglobulin A (sIgA), were measured as indices of the immune response to determine suitable levels of dietary ${\beta}$-1,3/1,6-glucan supplementation. The results indicated that performance was elevated quadratically with dietary ${\beta}$-1,3/1,6-glucan supplementation. Maximal growth performance and an enhanced immunological response were obtained at a supplemented level of 50 mg/kg.

  • Objectives : Daucus carota sativa has been frequently used as food supplements in many of the Asian countries, and a nutritional medical drug in traditional medicine. This research investigated the effects of Daucus carota sativa extract (DCE) on acute phases of inflammation in Raw 264.7 cells treated with lipopolysaccharide (LPS) in terms of the inhibition of nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$) and pro-inflammatory cytokines production. Methods : NO, $PGE_2$, tumor necrosis factor (TNF)-${\alpha}$, interleukin-$1{\beta}$ and interleukin-6 contents were assayed by ELISA, and expressions of inflammation-related proteins such as inducible NO synthase (iNOS) were determined by immunoblot analyses. Results : DCE treatment attenuated the LPS ability to increase the productions of NO and $PGE_2$ as well as the protein level of iNOS in a concentration-dependent manner. Consistently, treatment of the cells with DCE suppressed the production of TNF-${\alpha}$, interleukin-$1{\beta}$ and interleukin-6. DCE also caused decreases of inhibitor of ${\kappa}B{\alpha}$ phosphorylation induced by LPS in the cells, which means DCE inhibition of NF-${\kappa}B$ activity. Furthermore, DCE blocked LPS-induced phosphorylation of p38 and SAPK/JNK. Conclusion : This study showing here may be of help to understand the action mechanism of DCE, and provide the information for the medical use of Daucus carota sativa for the inflammatory disease.
