The aim of the present study is to investigate the anti-inflammatory effect of a vegetable soup (VS). The present study was designed to determine the effect of the vegetable soup on pro-inflammatory factors such as NO, iNOS and TNF-$\alpha$ in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The cell toxicity was determined by MTS assay. To evaluate the anti-inflammatory effect of vegetable soup, amount of NO was measured using the NO detection kit and the iNOS expression was measured by reverse transcriptase polymerase chain reaction (RT-PCR). Also, proinflammatory cytokines were measured by ELISA kit. The results showed that the vegetable soup reduced NO, iNOS and TNF-$\alpha$ production without cytotoxicity. Our results suggest that the vegetable soup may have an anti-inflammatory property through suppressing inflammatory mediator productions and appears to be useful to develop the functional food realted to anti-inflammation.

Objectives : Illicium verum Hook. f. has been known to possess antimicrobial, antioxidant, antifungal, anti-inflammatory, insecticidal, analgesic, sedative, convulsive activities, it has been rarely conducted to evaluate the immuno-biological activity. The present study was examined to evaluate the anti-inflammatory effects of the Illicium verum Hook. f. water extracts (IVE) in vivo and in vitro. Methods : Cell viability was measured by MTT assay. The relative levels of NO were measured with Griess reagent. iNOS, COX-2, $NF-{\kappa}B$ and target proteins were detected by immunoblot analysis, and levels of cytokines were analyzed by ELISA kit. Anti-edema effect was determined in the carrageenan (CA)-induced paw edema model in rats. Results : All dosages of IVE used in MTT assay had no significant cytotoxicity. The increases of NO production and iNOS expression were detected in LPS-treated cells compared with control. However, these increases were attenuated by treatment with IVE. Also, IVE reduced the elevated production of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 by LPS. IVE inhibited the $p-I{\kappa}B$ and translocation of $NF-{\kappa}B$ to nuclear. Furthermore, IVE significantly inhibited the increases of hind paw swelling, skin thicknesses and inflammatory cell infiltrations induced by CA injection. Therefore, IVE will be favorably inhibited the acute edematous inflammations. Conclusion : These results provide evidences that anti-inflammatory effect of IVE is partly due to the reduction of some inflammatory mediators by suppression of $NF-{\kappa}B$ pathway.

The crude galactomannans (GMs) were obtained from the culture of a newly isolated fungus Trichoderma erinaceum DG-312 and their anti-inflammatory activity was investigated in mice. The maximum concentrations of mycelial biomass and GMs reached 9.44 g/l, 2.72 g/l at day 3 in a 5-l stirred-tank bioreactor, respectively. The results of Sepharose CL-6B gel chromatography and compositional analysis revealed that the crude GMs contain heterogeneous polysaccharides consisting of $74.9\%$ mannose and $24.1\%$ galactose. The GMs was shown to possess a significant anti-inflammatory activity against acetic acid-induced inflammatory mouse model in a dose-dependent manner, when mice were treated with 100 and 200 mg GMs/kg body weight. The inhibition in vascular permeability $(60.6\%)$ and in writhing response $(62.5\%)$ evidenced an anti-inflammatory activity of the GMs. The marked anti-inflammatory and writhing-lowering properties of the GMs suggest its potential therapeutic use.

In this study, we investigated the variation in free sugars, amino acids, antioxidant activity, and anti-inflammatory activity of Solanum nigrum Linne based on harvest time. Major amino acids identified by HPLC analysis were proline, histidine, and serine. The highest content of total amino acids were found in S. nigrum aerial parts and roots harvested on July 10th and August 10th. Four kinds of free sugars (fructose, glucose, sucrose, maltose) were detected in S. nigrum, and the free sugar content varied significantly with harvest time. The fructose content of S. nigrum decreased with as harvest time increased. The total polyphenol content of S. nigrum was highest in those harvested on August 30th. The antioxidant activity of ethanol extract from S. nigrum collected at different harvest times were measured by DPPH and ABTS radical scavenging assays. The anti-inflammatory activity of these extracts were assayed via nitric oxide suppression in C6 glioma cells with a lipopolysaccharide (LPS)-induced inflammatory response. The anti-inflammatory activity and antioxidant effects were the highest in the extract from S. nigrum collected on August 30th. Good correlations were observed between antioxidant and anti-inflammatory activities in ethanol extract of S. nigrum roots harvested on August 30th.

Background: Although Korean Red Ginseng (KRG) has been traditionally used for a long time, its anti-inflammatory role and underlying molecular and cellular mechanisms have been poorly understood. In this study, the anti-inflammatory roles of KRG-derived components, namely, water extract (KRG-WE), saponin fraction (KRG-SF), and nonsaponin fraction (KRG-NSF), were investigated. Methods: To check saponin levels in the test fractions, KRG-WE, KRG-NSF, and KRG-SF were analyzed using high-performance liquid chromatography. The anti-inflammatory roles and underlying cellular and molecular mechanisms of these components were investigated using a macrophage-like cell line (RAW264.7 cells) and an acute gastritis model in mice. Results: Of the tested fractions, KGR-SF (but not KRG-NSF and KRG-WE) markedly inhibited the viability of RAW264.7 cells, and splenocytes at more than 500 mg/mL significantly suppressed NO production at $100{\mu}g/mL$, diminished mRNA expression of inflammatory genes such as inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor-${\alpha}$, and interferon-${\beta}$ at $200{\mu}g/mL$, and completely blocked phagocytic uptake by RAW264.7 cells. All three fractions suppressed luciferase activity triggered by interferon regulatory factor 3 (IRF3), but not that triggered by activator protein-1 and nuclear factor-kappa B. Phospho-IRF3 and phospho-TBK1 were simultaneously decreased in KRG-SF. Interestingly, all these fractions, when orally administered, clearly ameliorated the symptoms of gastric ulcer in HCl/ethanol-induced gastritis mice. Conclusion: These results suggest that KRG-WE, KRG-NSF, and KRG-SF might have anti-inflammatory properties, mostly because of the suppression of the IRF3 pathway.

Objectives: To observe the in vitro anti-inflammatory effects of Hyunbulikyung-tang aqueous extracts (HBLKT) and the possible synergic combination effects with a nonsteroidal anti-inflammatory drug, piroxicam. Methods: Anti-inflammatory effects of HBLKT (yield=16.17%) were observed on LPS activated raw 264.7 cells based on $ED_{50}$ to cell viability, NO, $PGE_2$, $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 productions as compared with piroxicam, in the present study. In addition, the combination effects of HBLKT with piroxicam were observed after treatment of HBLKT 1/4 $ED_{50}$ + piroxicam 1/4 $ED_{50}$, 1/8 $ED_{50}$, 1/16 $ED_{50}$, 1/32 $ED_{50}$ and 1/64 $ED_{50}$ concentrations, respectively. Results: Significant (p<0.01 or p<0.05) increases of cell viabilities and decreases of NO, $PGE_2$, $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 cytokine releases were detected in HBLKT 1/4 $ED_{50}$ + piroxicam 1/4 $ED_{50}$, 1/8 $ED_{50}$, 1/16 $ED_{50}$ and 1/32 $ED_{50}$ concentration co-treatment as compared with each of single 1/4 $ED_{50}$ concentration of piroxicam and HBLKT treatments, respectively. Although significant (p<0.01 or p<0.05) increases of cell viabilities and decreases of NO, $PGE_2$, $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 cytokine releases were also demonstrated in piroxicam 1/64 $ED_{50}$ + HBLKT 1/4 $ED_{50}$ co-treatment as compared with LPS control, no significant changes were detected as compared with each of single 1/4 $ED_{50}$ concentration of piroxicam and HBLKT treatments, in this experiment. Conclusions: Hyunbulikyung-tang showed cell protective and anti-inflammatory effects against LPS activated raw 264.7 cells. It, therefore, expected that HBLKT will be showed favorable effects to relieve dysmenorrhea related to over expressed inflammatory cytokines, and it also expected that the clinical dosages of piroxicam can be reduced as 1/8 levels as combination with HBLKT.

Portulaca oleracea L., a species of Portulacaceae, is ubiquitous. It is a well-known traditional Chinese medicine for removing heat, counteracting toxicity, cooling blood, and maintaining hemostasia; it is also used as antidysentery agent. This study investigated the anti-oxidative and anti-inflammatory activities of water and ethanol extracts from P. oleracea. The total polyphenol content ($21.08{\pm}0.03mg\;GAE/g$) and total flavonoid content ($5.45{\pm}0.76mg\;QE/g$) of the ethanolic extracts were higher than those of the water extracts. The antioxidative activities were determined by evaluating the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and the 2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging activity and by the ferric reducing antioxidant potential (FRAP) assay. The ABTS radical scavenging activity of the water extract (75.53%) was higher in those of the water extract (67.03%) at concentration of $1,000{\mu}g/mL$. The DPPH radical scavenging activity and FRAP of the ethanol extract were higher than those of the water extract. We also investigated the anti-inflammatory activity of the P. oleracea extracts in LPS-stimulated Raw 264.7 cells. The production levels of nitric oxide (NO) and reactive oxygen species (ROS) significantly decreased with an increasing concentration of the extract. The expression levels of pro-inflammatory cytokines (tumor necrosis faction (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, and IL-6) were significantly lower in the ethanol extract than in the LPS alone treatment group. Based on these results, ethanolic extract from P. oleracea could be an effective antioxidant and anti-inflammatory agent.

Nelumbo nucifera, also known as sacred lotus, has mainly been used as a food throughout the Asian countries. In the present study, we prepared ethanol extracts from leaf (NL), seed (NS), and seedpod (NSP) of Nelumbo nucifera and investigated their anti-inflammatory activities in mouse macrophage RAW 264.7 cells. To evaluate the anti-inflammatory activities of NL, NS, and NSP, nitric oxide (NO) production was measured in LPS-stimulated RAW 264.7 cells. NL, NS, and NSP significantly reduced NO production in a dose-dependent manner without affecting cell viabilities. NL, NS, and NSP dramatically decreased the protein expression of pro-inflammatory genes such as iNOS and COX-2. NL, NS, and NSP also suppressed phosphorylation of MAPKs and the nuclear translocation of $NF-{\kappa}B$ p65 indicating they have their anti-inflammatory activities via regulating mitogen-activated protein kinases (MAPKs) and nuclear factor kappa B ($NF-{\kappa}B$) pathways. In addition, we analyzed the production of reactive oxygen species (ROS) by the treatment of NL, NS, and NSP. All extracts reduced ROS production in a dose-dependent manner. And also, they increased heme oxygenase-1 (HO-1) protein expression and the nuclear translocation of nuclear respiratory factor 2 (Nrf2). In conclusion, our results suggest that Nelumbo nucifera has its anti-inflammatory activity via regulating MAPKs, $NF-{\kappa}B$, and Nrf2/HO-1 pathways.

Objectives: This study aimed to examine the safety, effects on proliferation of hair papilla cells, and anti-inflammatory and antioxidant mechanisms of Artemisia sieversiana Ehrh. ex Willd. (AS) extract. Methods: Safety tests through purity testing, acute toxicity tests, and repeated toxicity tests were performed using AS extract (ASE) which had been dried for over two years. Cell culture and proliferation tests were conducted; VEGF (vascular endothelial growth factor), bFGF (basic fibroblast growth factor), and EGF (epidermal growth factor) and protein expression analyses were performed for mechanistic evaluation; and inhibitory effects of ASE on the RNA expression of testosterone, 5𝛼-reductase, and aromatase was assessed. The anti-inflammatory and antioxidant efficacy of ASE was confirmed by measuring the levels of nitric oxide, inflammatory mediators (TNF-𝛼 and PGE2), inflammatory cytokines (IL-1𝛽, IL-6, and IL-8), and chemokine MCP-1. Results: The safety of ASE was confirmed. The mechanism of cell proliferation in human hair follicle dermal papilla cells involved the promotion of VEGF, bFGF, and EGF expression. ASE decreased mRNA expression of testosterone, 5𝛼-reductase, and aromatase-1 in a concentration-dependent manner. PGE2 and TNF-𝛼 production by inflammatory mediators was also significantly decreased in a concentration-dependent manner, and inflammatory cytokine and chemokine expression was inhibited. Conclusions: ASE is suggested to promote papillary cell growth at the cellular level, to suppress expression of various enzymes involved in hair cycle and cell death, and to inhibit hair loss through anti-androgen, anti-inflammatory, and antioxidant effects.
