  • In this study, Cyperus rotundus (C. rotundus) was fractionated into ethyl acetate to identify α-cyperone, a representative indicator, and its ethyl acetate fraction were evaluated to confirm the possibilityas a functional cosmetic ingredient. As a result of HPLC analysis, it was confirmed that the content of α-cyperone was 5.243%. In order to verify the inflammatory relief effect of the ethyl acetate fraction from C. rotundus (EAFC) and α-cyperone, it was confirmed that nitric oxide (NO) production inhibitory ability in RAW 264.7 macrophages induced an inflammatory reaction with lipopolysaccharide (LPS). Real-time qPCR analysis confirmed inhibition of mRNA expression level of inflammatory factors, IL-1β, IL-6, TNF-α, COX-2 and iNOS. As a results of conducting a clinical study using a simple cosmetic formulation containing EAFC, it was confirmed that the skin irritation stimulated by sodium lauryl sulfate (SLS) was calming and relieving itching. Through these results, it is believed that the C. rotundus can be used as a natural cosmetic ingredient that has the effect of inhibiting inflammation and relieving itching.

  • Adipocytes are endocrine cells that release bioactive mediators called adipokines. In condition of obesity characterized by low-grade chronic inflammation, adipocytes release inflammatory adipokines, which is related to insulin resistance. Bojungchiseub-tang (BJCST) has been used in symptoms and signs of edema, dampness-phlegm, kidney failure, and so on in Korean medicine. BJCST is also expected to have anti-obesity activities. In the present study, we examined whether BJCST modulate the production of inflammatory adipokines and the activations of the mitogen-activated protein kinases (MAPK) signaling pathway related to induce adipocyte inflammation to elucidate the effects and its mechanism of BJCST on lowering the content of inflammatory adipokines in 3T3-L1 adipocytes. As a result, BJCST suppressed the production of proinflammatory cytokines, tumor necrosis factor (TNF) $-{\alpha}$, interleukin (IL) $-1{\beta}$, IL-6, interferon (IFN) -${\gamma}$, granulocyte-macrophage colony-stimulating factor (GM-CSF), monocyte chemoattractant protein-1 (MCP-1), and the production of other inflammatory mediators, prostaglandin $E_2(PGE_2)$ and nitric oxide(NO)viadownregulationofcyclooxygenase-2(COX-2)andinducible NO synthase (iNOS) gene expressions. In addition, BJCST decreased the phosphorylation of MAPK that promotes the production of inflammatory adipokines in 3T3-L1 mature adipocytes. In conclusion, BJCST could regulate the production of inflammatory adipokines and MAPK signaling pathway related to induction of adipose inflammation.

  • Asthma is an increasing global health problem, and novel strategies to prevent or ameliorate the condition are needed. The purpose of the present study was to evaluate the anti-inflammatory and anti-asthma effects of Adenophora triphylla var. japonica extracts. We investigated the molecular mechanism underlying the effects of 80% ethanol extracts (AE) of A. triphylla on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. AE treatment inhibited pro-inflammatory cytokines such as TNF-${\alpha}$ and IL-6 as well as nitric oxide (NO) production in LPS-stimulated RAW 264.7 cells. In particular, NO and pro-inflammatory cytokine production was suppressed more effectively by aerial parts (AE-A) than roots (AE-R) of A. triphylla. Quantitative RT-PCR assay showed that AE reduced mRNA levels of iNOS and COX-2. We also evaluated the anti-asthmatic effects of AE-A in an ovalbumin (OVA)-induced BALB/c mouse model. AE-A supplementation significantly reduced the amounts of airway eosinophils, IL-4 and IL-13 levels in BALF, and IgE levels in serum as compared with untreated, OVA-induced mice. These results suggest that AE-A can be considered as a therapeutic agent to potentially relieve asthma.

  • Colon cancer is the third most common malignant neoplasm in the world and it remains an important cause of death, especially in western countries. The toxic environmental pollutant, 1, 2-dimethylhydrazine (DMH), is also a colon-specific carcinogen. Tannic acid (TA) is reported to be effective against various types of chemically induced toxicity and also carcinogenesis. In the present study, we evaluated the chemopreventive efficacy of TA against DMH induced colon toxicity in a rat model. Efficacy of TA against the colon toxicity was evaluated in terms of biochemical estimation of antioxidant enzyme activities, lipid peroxidation, histopathological changes and expression of early molecular markers of inflammation and tumor promotion. DMH treatment induced oxidative stress enzymes (p<0.001) and an early inflammatory and tumor promotion response in the colons of Wistar rats. TA treatment prevented deteriorative effects induced by DMH through a protective mechanism that involved reduction of oxidative stress as well as COX-2, i-NOS, PCNA protein expression levels and TNF-${\alpha}$ (p<0.001) release. It could be concluded from our results that TA markedly protects against chemically induced colon toxicity and acts plausibly by virtue of its antioxidant, anti-inflammatory and antiproliferative activities.

  • 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.

  • Objectives: The present study is focused on the inhibitory effect of the rhizome hexane fraction extract of Zingiberis Rhizoma Crudus (ginger hexan extract; GHE) on the production of inflammatory mediators such as NO, $PGE_2$, and proinflammatory cytokines in lipopolysaccharide (LPS)-stimulated BV2 cells, a mouse microglial cell line. Methods: We separated the hexane fraction from Zingiberis Rhizoma Crudus's methanol extract. The inhibitory and anti-inflammatory effect of GHE was examined on microglial activation. Results: GHE significantly inhibited the excessive production of NO, $PGE_2$, TNF-${\alpha}$, and IL-1${\beta}$ in LPS-stimulated BV2 cells. In addition, GHE attenuated the mRNA expressions and protein levels of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and proinflammatory cytokines. Conclusion: The anti-inflammatory properties of GHE may make it useful as a therapeutic candidate for the treatment of human neurodegenerative diseases.

  • Dioscoreae Rhizome (DR) has been used in traditional medicine to treat numerous diseases and is reported to have anti-diabetes and anti-tumor activities. To identify a bioactive traditional medicine with anti-inflammatory activity of a water extract of DR (EDR), we determined the mRNA and protein levels of proinflammatory cytokines in macrophages through RT-PCR and western blot analysis and performed a FACS analysis for measuring surface molecules. EDR dose-dependently decreased the production of NO and pro-inflammatory cytokines such as IL-$1{\beta}$, IL-6, TNF-${\alpha}$, and $PGE_2$, as well as mRNA levels of iNOS, COX-2, and pro-inflammatory cytokines, as determined by western blot and RT-PCR analysis, respectively. The expression of co-stimulatory molecules such as B7-1 and B7-2 was also reduced by EDR. Furthermore, activation of the nuclear transcription factor, NF-${\kappa}B$, but not that of IL-4 and IL-10, in macrophages was inhibited by EDR. These results show that EDR decreased pro-inflammatory cytokines via inhibition of NF-${\kappa}B$-dependent inflammatory protein level, suggesting that EDR could be a useful immunomodulatory agent for treating immunological diseases.

  • Objectives : Jinnoe-san (JNS) is a novel herbal formula consisting of five oriental medicinal herbs including Polygalae Radix, Prunellae Spica, Perillae Herba, Betulae Cortex, and Lonicerae Flos. In this study, we investigated the effects and molecular mechanism of JNS on Parkinson's disease in vitro model. Methods : The effects of JNS on 1-methyl-4-phenylpyridinium ($MPP^+$)-induced cell death in SH-SY5Y cells were evaluated with a cell viability assay, flow cytometry, and western blots analysis. The effects of JNS on lipopolysaccharide (LPS)-stimulated BV2 microglia were determined with a nitric oxide (NO) assay, enzyme linked immunosorbent assays, and western blots analysis. Result : $MPP^+$-induced cell death in SH-SY5Y cells was significantly reduced by JNS pre-treatment in a dose-dependent manner. JNS inhibited the production of reactive oxygen species, mitochondria dysfunction, and apoptosis induced by $MPP^+$ in SH-SY5Y cells. Furthermore, JNS significantly activated Akt and ERK in SH-SY5Y cells and the ability of JNS to prevent mitochondria dysfunction by $MPP^+$ was antagonized by pre-treatment of LY294002 and PD98059, an Akt and ERK inhibitor, respectively. In addition, JNS inhibited LPS-induced NO and $PGE_2$ production as well as iNOS expression and secretion of TNF-${\alpha}$, pro-inflammatory cytokines without affecting the cell viability. JNS also suppressed LPS-induced ERK activation. Conclusions : These results demonstrate that JNS has a protective effect on the dopaminergic neurons against $MPP^+$-induced neurotoxicity and anti-inflammatory effect on the LPS-stimulated microglia. These findings provide evidences for JNS to be considered as a new prescription for treating Parkinson's disease.

  • Asterias amurensis is a marine organism that causes damage to the fishing industry worldwide; however, it has been considered a promising source of functional components. The present study aimed to investigate the immune-enhancing effects of fatty acids from three organs of A. amurensis on murine macrophages (RAW 264.7 cells). A. amurensis fatty acids boosted production of immune-associated factors such as nitric oxide (NO) and prostaglandin E2 in RAW 264.7 cells. A. amurensis fatty acids also enhanced the expression of critical immune-associated genes, including iNOS, $TNF-{\alpha}$, $IL-1{\beta}$, and IL-6, as well as COX-2. Western blotting showed that A. amurensis fatty acids stimulated the $NF-{\kappa}B$ and MAPK pathways by phosphorylation of $NF-{\kappa}B$ p-65, p38, ERK1/2, and JNK. A. amurensis fatty acids from different tissues resulted in different levels of $NF-{\kappa}B$ and MAPK phosphorylation in RAW 264.7 cells. The results increase our understanding of how A. amurensis fatty acids boost immunity in a physiological system, as a potential functional material.
