  • Objectives : Fermentation of herbs has been known to be helpful in improving the immune systems and protecting body against disease. The present study was conducted to evaluate anti-inflammatory effects of the fermentation extracts (FE) consisting of soybean, red ginseng andCitrus UnshiuPeel in lipopolysaccharide (LPS)-activated Raw264.7 cells.Methods : FE were prepared by the fermentation withBacillus Subtilisand then by extraction with ethanol (95%; prepared by the fermentation process). Cell viability was measured by MTT assay. Nitric oxide (NO) production was measured in culture media by Griess assay. The expression of nuclear factor (NF)-κB and inhibitory kappa B alpha (IκBα) was determined by Western blot.Results : LPS-induced production of NO and PGE2was dose-dependently decreased by the treatment of FE in Raw264.7 cells. These suppressive effects of FE on NO and PGE2production were related to the inhibition of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression. FE inhibited LPS-induced production of pro-inflammatory cytokines, TNF-α, IL-6, and IL-1βin a dose-dependent manner. Furthermore, FE inhibited the NF-κB signaling pathway through the prevention of LPS-induced degradation of IκBαin cytosol and the nuclear translocation of NF-κB.Conclusions : These findings suggest that FE could have anti-inflammatory effects on LPS-induced inflammatory responses in macrophages.

  • Pro-inflammatory mediators, such as prostaglandin $E_2$ (PGE2), nitric oxide (NO), and cyclooxygenases-2 (COX-2), play pivotal roles in normal as well as transformed cells. Previous studies have shown that Euphorbiae humifusae Wind exhibits anti-proliferative and antioxidant activities. However, the it's anti-inflammatory properties are unclear. In this study, we examine the effects of water extract of E. humifusae (WEEH) on the expression of COX-2 and the production of $PGE_2$ in human lymphatic U937 cells. Treatment of phorbol 12-myristate-13-acetate (PMA) significantly induced COX-2 expression and $PGE_2$ production in U937 cells. However, pretreatment WEEH markedly inhibited the PMA-induced COX-2 expression and $PGE_2$ production in a dose-dependent manner. Moreover, WEEH prevented the elevated early growth response gene-1 (Egr-1) expression and nuclear factor-kappaB ($NF{-\kappa}B\; p65$) nuclear translocation stimulated by PMA treatment. Taken together, the present data indicate that WEEH exhibits anti-inflammatory properties by suppressing the transcription of pro-inflammatory cytokine genes through the $NF{-\kappa}B$ and Egr-1 signaling pathway.

  • The aim of this study was to investigate the synergistic anti-inflammatory effect of rosmarinic acid (RA) and luteolin from perilla (Perilla frutescens L.) leaves in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. A combination of RA and luteolin more strongly inhibited the production of nitric oxide (NO), inducible NOS (iNOS), prostaglandin $E_2$ ($PGE_2$), and COX-2 than higher concentrations of RA or luteolin alone in LPS-stimulated RAW264.7 macrophages. The combined RA and luteolin synergistically inhibited the production of pro-inflammatory cytokines, such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-6 (IL-6), and interleukin-$1{\beta}$ (IL-$1{\beta}$), in LPS-stimulated RAW264.7 macrophages. Furthermore, combined RA and luteolin more strongly suppressed NF-${\kappa}B$ activation than RA or luteolin alone, by inhibiting the degradation of inhibitor of NF-${\kappa}B(I{\kappa}B)$-${\alpha}$ and nuclear translocation of the p65 subunit of NF-${\kappa}B$ in LPS-stimulated RAW264.7 macrophages. Collectively, these results suggest that RA and luteolin in combination exhibit synergistic effects in suppression of LPS-induced inflammation in RAW264.7 macrophages.

  • Objectives : The aim of this study was verification of the anti-oxidative and anti-inflammatory effects of Odukhwan(ODH) and Sasinhwan(SSH) in mouse macrophage, RAW264.7 cells. Methods : To investigate the anti-oxidative effect and scavenging activities of DPPH radical, superoxide anions, nitric oxide and peroxynitrite were measured. Cytotoxic activity of extract of ODH and SSH on RAW264.7 cells was measured using MTS assay. To proof the reductive activity of intracellular oxidation, DCFH-DA assay was performed. The nitric oxide(NO) production was measured and pro-inflammatory cytokines and $PGE_2$ were measured by ELISA kit. The levels of inducible nitric oxide synthase(iNOS), cyclooxygenase-2(COX-2) and nuclear NF-${\kappa}B$ p65 expression were detected by western blot. Results : After those analyses, we bring to a conclusion as follows. Both herbal formulations scavenged DPPH radical and nitric oxide. But ODH had no scavenging activity of superoxide anions and SSH had low scavenging activity in peroxynitrite. And the results indicated that ODH and SSH inhibited the LPS-induced NO, $PGE_2$ production and iNOS, COX-2 expression accompanied by an attenuation of IL-$1{\beta}$ and IL-6 production in RAW264.7 cells. They also have suppression effects of LPS-induced NF-${\kappa}B$ activation. Conclusions : ODH and SSH have anti-oxidative and anti-inflammatory effects and they may be a part of database for development of new anti-oxidative and anti-inflammatory drugs.

  • Recently, Korean ginseng, as immuno-activator, was actively investigated on its effect and mechanism. But purified fermented red ginseng (PFRG) has not been researched enough compared to red ginseng (RG, steamed and dried root of Panax ginseng C. A. Meyer, family Araliaceae) and fermented red ginseng (FRG, fermented red ginseng by Lactobacillus brevis 13094). In this study, we examined RG, FRG and PFRG to compare their anti-inflammatory effect by LPS. According to the result, RAW 264.7 cells survival rates did not largely change by RG and FRG. Only PFRG expressed weak toxicity at 10 ug/ml. The expression of iNOS and production of Nitric Oxide (NO) decreased depending on the concentration of RG, FRG and PFRG. And the expression of COX-2 also decreased. We tried western blotting for detecting that the expression of iNOS, COX-2 was caused by NF-${\kappa}B$. The result supported that the inhibition of NF-${\kappa}B$ by RG, FRG and PFRG suppressed the expression of iNOS, COX-2 and affected the production of TNF-${\alpha}$. While the anti-inflammatory effect was confirmed from all three types of red ginseng (RG, FRG, PFRG), the effect of PFRG was superior to others. Further research is required on other effects of PFRG.

  • Objectives Hataedock is a Korean herbal medical oral treatment that removes fetal toxic heat and meconium from new born babies. The purpose of this study is to evaluate whether Hataedock treatment of Duchi extracts has anti-inflammation effects on AD (Atopic Dermatitis)-induced NC/Nga mice. Methods After Hataedock treatment of Duchi extracts on days 0, 3-week-old NC/Nga mice were sensitized on days 28, 35, 42 by exposure of DNFB (dinitrochlorobenzene) and were induced to have AD. Immunohistochemistry of NF-${\kappa}B$ p65, iNOS, COX-2 and TUNEL assay of apoptotic body was used to identify changes of skin damages and anti-inflammation effects. Results The alleviate effect of the skin damage and angiogenesis was observed in DT group. The damage of stratum corneum, hyperplasia, edema, infiltration of lymphocytes and distribution of capillary were decreased in DT group. Also, the study results suggested that Hataedock treatment of Duchi extracts in DT group remarkably downregulated levels of NF-${\kappa}B$ p65 by 70% (p < 0.001), as well as COX-2 by 51%, iNOS by 62% (p < 0.001). Additionally, Hataedock treatment of Duchi extracts in DT group up-regulated apoptosis of inflammatory cells by 68% in atopic dermatitis-like skin lesion. Conclusions From the study results, we observed that Hataedock treatment of Duchi extracts alleviates AD through diminishing various inflammatory cytokines in the skin lesions, which are involved in the initial steps of AD development. It is anticipated to have potential applications for prevention and treatment of atopic dermatitis.

  • Poncirus Fructus (PF) is obtained by drying the trifoliate orange fruit belonging to the Rutaceae family. In our country of medicine, PF has been used as a treatment of indigestion, allergy and inflammation. But Mechanism and medical data for PF is insignificant. Recently, the effect of the study PF of biological activity was reported, such as anti- thrombosis, anti-bacteria, anti-virus, anti- allergic. We investigated that the effect of PF on anti-inflammatory in murine macrophage-like cell line Raw264.7 cells. Our results show that the expression level of Nitric Oxide (NO) and Matrix-metallopeptidase-9 (MMP-9) significantly decreased. Moreover, to determine the expression level of pro-inflammatory cytokines such as Tumor Necrosis Factor ($TNF-{\alpha}$) and Interleukin-6 (IL-6) and the phosphorylation pattern of signaling molecules of mitogen-activated protein kinase (MAPK) family, we performed ELISA and westren blot in Raw264.7 cells. In addition, nuclear factor-kappa B ($NF-{\kappa}B$) pathway was confirmed. PF extract inhibited the production of $TNF-{\alpha}$ and IL-6. The extract suppressed the phosphorylation of ERK1/2, JNK, and p38 MAPK, and the nuclear translocation of $NF-{\kappa}B$ p65 in activated cells. Our results suggest that PF can be used as a potential therapeutic agent or functional food to relieve inflammation.

  • Hijikia fusiforme (HF), a member of brown algae family, exerts various pharmacological effects, including preventing arteriosclerosis and menopausal disorders. This study aimed to elucidate the ameliorative effect of HF on skin inflammation. We investigated the antioxidant and anti-inflammatory effect of HF extract to evaluate its potential as a functional materials. The antioxidant activity of HF was determined using 2,2-diphenyl-1-picrylhydrazy (DPPH) scavenging and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS+) scavenging. To determine the pharmacological mechanism of HF in inflammatory reaction, we evaluated the effects of HF on interleukin (IL)-8, IL-6 and tumor necrosis factor (TNF)-α production and nuclear factor-κB (NF-κB) activation in activated- human mast cells (HMC)-1. Results showed that HF had the high DPPH and ABTS+ radical scavenging activity, and it suppressed IL-8, IL-6 and TNF-α production in a concentration-dependent manner. Moreover, HF significantly ameliorated NF-kB activation in activated-HMC-1. Hence, these results provide evidence that HF's potential for skin inflammation therapy.

  • Lycopene, found in tomatoes and tomato products, has antioxidant, anticancer, and anti-inflammatory effects. High-mobility-group box 1 (HMGB1) mediates the pro-inflammatory responses in several inflammatory diseases. In this study, the potential roles of lycopene in the HMGB1-mediated pro-inflammatory gene expressions in the primary human-umbilical-vein endothelial cells (HUVECs) were investigated. The data showed that HMGB1 upregulated the expressions of monocyte chemotactic protein 1 (MCP-1), interleukin-6 (IL-6), secretory phospholipase A2 (sPLA2)-IIA, and prostaglandin E2 (PGE2). Lycopene pre-incubation for 6 h decreased the HMGB1-mediated induction of MCP-1, IL-6, sPLA2-IIA, and PGE2. Further study revealed that the inhibitory effects of lycopene on the HMGB-1 induced expression of pro-inflammatory genes were mediated by the inhibition of two important inflammatory cytokines: tumor necrosis factor (TNF)-${\alpha}$ and nuclear factor (NF)-${\kappa}B$. These results suggest that HMGB1 upregulated the expression of pro-inflammatory genes and lycopene inhibited HMGB-1-induced pro-inflammatory genes by inhibiting TNF-${\alpha}$ and NF-${\kappa}B$. This finding will serve as an important evidence in the development of a new medicine for the treatment of inflammatory diseases.
