  • Mahwanghangingamchosukgo-tang (MH) is recorded as a treatment to treat exterior-related respiratory diseases in the Korean medicine. In this study, we examined the anti-inflammatory effects of MH, using MH water extract and lipopolysaccharide (LPS)-induced RAW 264.7 cells. First of all, we measured the amount of nitric oxide (NO) and prostaglandin E2 (PGE2), the products of inflammatory metabolism. Also, we measured enzymes such as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), as well as cytokines such as interleukin 6 (IL-6), interleukin 1 alpha (IL-1α), and interleukin 1 beta (IL-1β). MH suppressed the production of NO and PGE2 in a dose dependent manner and reduced the amount of protein and the mRNA expression of iNOS and COX-2. Also, MH reduced the mRNA expression of IL-6, IL-1α and IL-1β. In conclusion, MH decreased production of LPS-induced inflammatory factor, which could be a clinical basic subject for inflammatory diseases.

  • Objectives : Many of currently used anti-cancer drugs were developed to target cell death mechanisms and had serious side effects by causing damage to normal cells. Hangambujeongsan or Kangai Fuzheng Powder was a mixture based on the traditional Chinese medicine. It had been used in the local Chinese hospitals to treat cancer patients for decades and had shown a certain level of beneficial effects without major toxic effects. But its mechanism of action had not been elucidated yet. Thus this study aimed to investigate the effects of Kangai Fuzheng Powder in an in vitro experiment. Methods : Cancer lines or RAW264.7 mouse macrophage cells were treated with Kangai Fuzheng Powder. Cell viability was measured by MTT assay, and morphological observation was also performed. Gene expression of cytokines in macrophages was determined by real-time polymerase chain reaction. Phagocytic function assay was also performed in macrophage cells. Results : Kangai Fuzheng Powder had no direct detrimental effect on cancer cells. When macrophages were co-cultured with cancer cells, Kangai Fuzheng Powder had toxic effect on cancer cells. After exposing macrophages to Kangai Fuzheng Powder, macrophages transformed into activated form and the mRNA level of tumor necrosis factor-alpha, interleukin-1beta, interleukin-6, interleukin-10 and monocyte chemotactic protein-1 was significantly enhanced. Phagocytic activity of macrophages was dramatically potentiated. Conclusions : We demonstrated that anti-cancer effect of Kangai Fuzheng Powder was related to activation of macrophages including enhanced cytokine production and phagocytic function.

  • Mitogen-activated protein (MAP) kinases play an important role in cell growth and differentiation, as well as the modulation of proinflammatory cytokines. The objective of this study was to examine the increase in the anti-inflammatory effect of Gentiana scabra Bunge (GSB), due to bioconversion with the Aspergillus kawachii crude enzyme, via inhibition of the $NF-{\kappa}B$ signaling and MAP kinase pathways in RAW 264.7 cells. The expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 in RAW 264.7 cells treated with the GSB ethyl acetate fraction bioconverted with A. kawachii crude enzyme (GE-BA), was dramatically suppressed as compared to GSB ethyl acetate fraction non-bioconverted with the A. kawachii crude enzyme (GE-UA). The phosphorylation of p38, extracellular signal-regulated kinases, and inhibitory ${\kappa}B$ in RAW 264.7 cells treated with GE-BA was further suppressed, as compared to exposure to GE-UA. Moreover, the mRNA expression of interleukin 6, interleukin 1-beta, and tumor necrosis $factor-{\alpha}$ was further suppressed by GE-BA, compared to GE-UA. Similarly, anti-oxidant activities, such as 2,2-diphenyl-1-picrylhydrazyl hydrate and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging activity, of GE-BA were further increased compared to GE-UA. These observations demonstrate that the anti-oxidant and anti-inflammatory activities of GSB ethyl acetate fraction increases as a result from bioconversion with the A. kawachii crude enzyme.

  • The essential oil fraction was obtained from the underground parts o of Ligusticum chuanxiong (Umbelliferae) by steam distillation, and its main components, Z-ligustilide and butylidene phthalide, were isolated by column chromatography. Its essential oil fraction and the isolated main components were examined for effects on their anti-inflammatory properties in RAW 264.7 macrophage cells to develop a new natural anti-inflammatory drug. The results showed that the L. chuanxiong essential oil fraction and its main components, Z-ligustilide and butylidene phthalide, inhibited the production of nitric oxide significantly in lipopolysaccharide (LPS)-treated RAW 264.7 cells. LPS-induced interleukin-$1{\beta}$ (IL-$1{\beta}$), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-$\alpha$) production was also decreased in a dose-dependent manner. In addition, western blot analysis revealed that the L. chuanxiong essential oil fraction and also its main components, Z-ligustilide, and butylidene phthalide reduced the expression levels of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS).

  • Cheongpyesagan-tang (CP) is one of the traditional medicinal prescription to treat Taeumin (太陰人)'s disease. It has been commonly used for the treatment of stroke, arthritis, diabetes and obesity. In this study, we investigated an anti-inflammatory potential of CP water extract. We examined the effects of CP on the lipopolysarccharide (LPS)-induced production of nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$). We also examined the levels of protein or mRNA of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and proinflammatory cytokines in RAW 264.7 cells. CP inhibited NO and $PGE_2$ production in a dose dependent manner and decreased the protein and mRNA expression of iNOS and COX-2. Also, CP decreased the mRNA expression of interleukin-6 (IL-6), interleukin-$1{\beta}$ (IL-$1{\beta}$), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$). These results suggest that CP has potential as anti-inflammatory therapeutic medicine.

  • Celastrus hindsii (family Celastraceae) is located abundantly in the United States, China, and Vietnam, where it is utilized as a traditional herbal and traditional drug for the care of cancer. However, the antioxidant and anti-inflammatory effects of Celastrus hindsii extract are unknown. In our research, the antioxidant activity of Celastrus hindsii leaf extract was investigated, and then anti-inflammatory efficacy of C. hindsii extract in lipopolysaccharide (LPS)-induced RAW264.7 cells. First, our results revealed that C. hindsii extract showed powerful antioxidant capability. Moreover, the application of C. hindsii extract significantly reduced nitric oxide (NO) production without cytotoxic effects. Furthermore, C. hindsii extract reduced the generation of pro-inflammatory cytokines, like as interleukin (IL)-6, IL-1β, and TNF-α. Our results are the first to confirm the anti-inflammatory capability of C. hindsii extract in RAW264.7 cells.

  • BACKGROUND/OBJECTIVES: Several pharmacological properties of red rice extract have been reported including anti-oxidant, anti-tumor, and reduced cancer cell invasion. This study was conducted to evaluate the anti-inflammatory effects of red rice extract on the production of inflammatory mediators in lipopolysaccharide (LPS)-induced Raw 264.7 macrophages. MATERIALS/METHODS: Pro-inflammatory cytokines including tumor necrosis factor-${\alpha}$ and interleukin-6 were determined by ELISA and cyclooxygenase-2 and inducible nitric oxide synthase expression was evaluated using western blot analysis. In addition, the signaling pathway controlling the inflammatory cascade such as nuclear factor kappa B ($NF-{\kappa}B$), activator proteins-1 (AP-1), and mitogen-activated protein kinase (MAPK) was determined. RESULTS: Our results showed that red rice polar extract fraction (RR-P), but not non-polar extract fraction, inhibited interleukin-6, tumor necrosis factor-${\alpha}$, and nitric oxide production in LPS-induced Raw 264.7 cells. RR-P also reduced the expression of inflammatory enzymes, inducible nitric oxide synthase, and cyclooxygenase-2. In addition, activation of AP-1 and $NF-{\kappa}B$ transcription factor in the nucleus was abrogated by RR-P. RR-P inhibited the phosphorylation of extracellular signaling-regulated kinase 1/2, c-Jun NH2-terminal kinase, and p38 MAPK signaling responsible for the expression of inflammatory mediators in LPS-stimulated Raw 264.7 cells. Based on chemical analysis, high amounts of proanthocyanidin and catechins were detected in the RR-P fraction. However, only proanthocyanidin reduced $NF-{\kappa}B$ and AP-1 activation in LPS-activated Raw 264.7 cells. CONCLUSION: These observations suggest that the anti-inflammatory properties of RR-P may stem from the inhibition of pro-inflammatory mediators via suppression of the AP-1, $NF-{\kappa}B$, and MAPKs pathways.

  • Asterias amurensis (starfish) is a marine organism that is harmful to the fishing industry, but is also a potential source of functional materials. The present study was conducted to analyze the profiles of fatty acids extracted from A. amurensis tissues and their anti-inflammatory effects on RAW264.7 macrophage cells. In different tissues, the component ratios of saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids differed; particularly, polyunsaturated fatty acids such as dihomo-gamma-linolenic acid (20:3n-6) and eicosapentaenoic acid (20:5n-3) were considerably different. In lipopolysaccharide-stimulated RAW264.7 cells, fatty acids from A. amurensis skin, gonads, and digestive glands exhibited anti-inflammatory activities by reducing nitric oxide production and inducing nitric oxide synthase gene expression. Asterias amurensis fatty acids effectively suppressed the expression of inflammatory cytokines such as tumor necrosis $factor-{\alpha}$, interleukin-$1{\beta}$, and interleukin-6 in lipopolysaccharide-stimulated cells. Cyclooxygenase-2 and prostaglandin $E_2$, which are critical inflammation biomarkers, were also significantly suppressed. Furthermore, A. amurensis fatty acids reduced the phosphorylation of nuclear $factor-{\kappa}B$ p-65, p38, extracellular signal-related kinase 1/2, and c-Jun N-terminal kinase, indicating that these fatty acids ameliorated inflammation through the nuclear $factor-{\kappa}B$ and mitogen-activated protein kinase pathways. These results provide insight into the anti-inflammatory mechanism of A. amurensis fatty acids on immune cells and suggest that the species is a potential source of anti-inflammatory molecules.

  • Objectives: The purpose of this study is to evaluate anti-breast cancer and anti-inflammatory effects of Chungganhaewool-tang and Shipyeukmiyeugi-eum. Methods: MDA-MB-231 cells were used to measure cytotoxicity, Reactive oxygen species (ROS) production, protein expression amounts of Bcl-2-associated X protein (Bax), B-cell lymphoma 2 (Bcl-2), B-cell lymphoma-extra large (Bcl-xl), Cytochrome C Caspase-3, Caspase-7, Caspase-9, Poly ADP-ribose polymerase (PARP), Nuclear factor erythroid-2-related factor 2 (Nrf2), Heme oxygenase-1 (HO-1) and NAD (P) H Quinone Oxidoreductase 1 (NQO1) to evaluate the anti-breast cancer effects of Chungganhaewool-tang (CHT) and Shipyeukmiyeugi-eum (SYE), and THP-1 cells, differentiated into macrophage and induced inflammation with Lipopolysaccharide (LPS), were used to measure production amounts of ROS, Nitric oxide (NO), and protein expression amounts of Inducible nitric oxide synthase (iNOS), Cyclooxygenase (COX-2), Interleukin-1 beta (IL-1β), Interleukin-6 (IL-6) and Tumor necrosis factor-alpha (TNF-α) to evaluate the anti-inflammatory effects of CHT and SYE. Results: CHT and SYE reduced MDA-MB-231 cell counts, increased protein expression of Bax and Cytochrome C, and decreased protein expression of Bcl-2, Bcl-xl. The protein expression amounts of Caspase-3, 7, and 9 decreased, but amounts of the active form, cleaved Caspase-3, 7, and 9, increased. In addition, PARP protein expression decreased, the amount of PARP protein in the cleaved form increased, and the amount of protein expressions of Nrf2 and HO-1 decreased, but NQO1 showed no significant difference. In THP-1 cells CHT and SYE reduced ROS and NO, and reduced protein expressions of iNOS, COX-2, IL-1, and TNF-α, but only SYE groups reduced IL-6. Conclusions: This study suggests that CHT and SYE have potential to be used as treatments for breast cancer.
