Previously, agar obtained from Gelidum sp. has a small molecular weight and has the disadvantage of inherent viscosity properties and poor functionality as a dietary fiber. In order to improve aforementioned disadvantages, agar having a fluidity that can be added to food at a higher concentration that a powder agar having a gelling property at low concertation was manufactured. In addition, the anti-inflammatory activity of agar hydrolysates was evaluated to confirm their potential as a functional material. As a result, agar hydrolysates significantly reduced NO levels secreted by LPS-activated macrophages and inhibited the expression of iNOS and COX-2, which are inflammatory mediators that regulates NO secretion in macrophages. Furthermore, in in vivo zebrafish embryos model results demonstrated significant reduction of LPS induced NO production after the treatment of agar hydrolysate hydrolyzed for 360 min. In addition, ROS production and cell death by stresses were also reduced in LPS-exposed embryos after the treatment of agar hydrolysis product hydrolyzed for 360 min. Taken together, agar hydrolysate hydrolyzed for 360 min can be easily added into food due to their fluidity and used as a food ingredient that inhibits inflammation due to their anti-inflammatory property.

The present study was performed to examine the possible anti-inflammatory effects of a herbal drug ASCH in RAW264.7 cell line. Inflammation was induced by LPS toxin treatment to RAW264.7 macrophage cell line. Increases in cytokine production such as IL-1β, IL-6. and IL-18, COX-2, NOS-Ⅱ (iNOS), and TNF-alpha were observed at mRNA level in the LPS-treated RAW264.7 cells. Measurement of IL-6, nitric oxide and the reactive oxygen species (ROS) showed increased production of these inflammation mediators. Treatment of ASCH effectively decreased IL-1β protein in a dose-dependent manner, and IL-6 and IL-18 were reduced at 100㎍/㎖ of ASCH concentration. NO production was also decreased by ASCH treatment. A slight inhibition for TNF-alpha in terms of protein, but not mRNA level was obtained by 100㎍/㎖ of ASCH treatment. ASCH treatment to normal RAW264.7 cells did not produce any cytotoxicity, indicting that the action of ASCH was selective to inflammatory cells. Thus, the present data suggest that ASCH may act as an important regulator to alleviate the inflammatory symptoms.

Black-red ginseng (BRGP) exhibits more potent biological activities than white and red ginseng. However, the effect of BRGP on allergic inflammation has not been studied extensively. In this study, we attempted to evaluate the effects of BRGP on allergic inflammation in vitro and in vivo. The effects of BRGP on pro-inflammatory mediators in phorbol myristate acetate (PMA) and A23187-stimulated human mast cells (HMC-1) and on trimellitic anhydride (TMA)-induced atopic dermatitis-like skin lesions in BALB/c mice were evaluated. BRGP suppressed the expression of $TNF-{\alpha}$, IL-6 and IL-8 from HMC-1 stimulated with PMA and A23187. Furthermore, the oral administration of BRGP markedly significantly reduced apparent severity of atopic dermatitis-like skin lesions, ear swelling, lymph node weight gains and serum IgE levels induced by TMA in mice. BRGP treatment also ameliorated epidermal hyperplasia and infiltration of inflammatory cells including mast cells. Taken together, BRGP possesses significant anti-atopic efficacy, suggesting that it could be used as a potential therapeutic agent for allergic inflammatory diseases, including atopic dermatitis.

The pistil of nelumbo nucifera (PNN) is used in the treatment of nocturnal pollution, hematemesis, epistaxis, metrorrhagia and diarrhoea in traditional medicine. The present study was examined to evaluate the effects of PNN on the production of pro-inflammatory mediators in vitro. After the treatment of PNN, cell viability was measured by MTT assay, nitric oxide (NO) production was monitored by measuring the nitrite content in culture medium. The protein bands were determined by immunoblot analysis and levels of cytokines were analyzed by sandwich immunoassays. In the MTT assay, the doses of PNN extract (0.03, 0.10 mg/ml) had no significant cytotoxicity. The increases of NO production and inducible nitric oxide synthase expression were detected in lipopolysaccharide(LPS)-activated Raw 264.7 cells compared with control, in contrast, these increases were significantly attenuated by pre-treatment with PNN. In cytokine assay, the massive pro-inflammatory cytokines such as tumour necrosis factor-$\alpha$, interleukin (IL)-$1{\beta}$ and IL-6 were induced in LPS-activated Raw 264.7 cells, but pre-treatment of Raw 264.7 cells with PNN caused inhibition (TNF-$\alpha$=14.17%, IL-$1{\beta}$=107.43%, IL-6=46.27%) the production of cytokines by LPS. In addition, PNN reduced prostaglandin E2 productions in a dose-dependent manner (0.03mg/ml=37.52%, 0.10 mg/ml=83.77%) as a consequence of the inhibition of cyclooxygenase-2 expression. Taken together, our data indicates that PNN can regulate the inflammatory response in macrophage cells activated by Gram-negative infection.

Kagam-bojungikgitang is the water extracts prepared from Ginseng Radix, Astragali Radix. Angelicae gigantis Radix, Astractylodis Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Artemisiae iwayomogii Herba, and Scutellariae Radix. This is a modified prescription of Bojungikgitang, which has been used for the treatment of indigestion, and immunological disease in oriental countries. In this study, the effects of Kagam-bojungikgitang and Bojungikgitang on the production of prostaglandin E₂ (PGE₂) and the expression of cyclooxygenase-2 (COX-2) were examined using RAW 264.7 macrophages activated with lipopolysaccharide (LPS). Both prescriptions dose-dependently reduced the release of PGE2 and expression of COX-2 caused by stimulation of LPS without cytotoxic effect. Kagam-bojungikgitang's inhibitory effects were better than Bojungikgitang in PGE2 production and COX-2 expression. Moreover, Kagam-bojungikgitang also attenuated markedly the production of tumor necrosis factor (TNF)-α, and IL-6 than Bojungikgitang in LPS-stimulated RAW 264.7 macrophages. These results suggest that Kagam-bojungikgitang decreases PGE2 and pro-inflammatory cytokine production in macrophages and these properties may contribute to the anti-inflammatory activity of Kagam-bojungikgitang.

Protulaca oleracea, a widely distributed weed, has been reported to exhibit different health promoting effects. The objective of this study was to evaluate the anti-oxidative and anti-inflammatory effects of P. oleracea on LPS-stimulated AGS cells. The cytotoxicity of P. oleracea in AGS cells was examined by MTT assay. The anti-oxidative effects of P. oleracea were examined by DPPH assay. RT-PCR was carried out to examine the effect of P. oleracea in the mRNA expression of different inflammatory mediators. MTT assay revealed that P. oleracea have almost no cytotoxity in AGS cells. DPPH radical scavenging activities were better than butylated hydroxyl toluene (BHT). The mRNA expression of different endogenous anti-oxidative enzymes (SOD2, GPx3 and catalase) were preserved by P. oleracea in AGS cells. The nitric oxide production and expression of iNOS in LPS stimulated RAW264.7 were suppressed in P. oleracea treated groups. Based on these findings, P. oleracea has protective anti-oxidant and anti-inflammatory effects.

Purpose: This study was performed to determine anti-imflammatory effects of Haedoksamultang. Methods: In this study, I examined the effects of Haedoksamultang on the production of nitric oxide(NO), tumor necrosis factor-${\alpha}$(TNF-${\alpha}$), and interlukin-1${\beta}$(IL-1${\beta}$) as well as the expression of inducible NO synthase(iNOS), cyclooxygenase-2(COX-2), TNF-${\alpha}$, and IL-1${\beta}$ in RAW 264.7 cells. Haedoksamultang inhibited LPS-stimulated NO production. Western blotting and RT-PCR analysis showed that Haedoksamultang suppressed LPS-induced iNOS and COX-2 protein and mRNA expression in RAW 264.7 cells. Haedoksamultang also suppressed the expression and production of LPS-stimulated TNF-${\alpha}$ and IL-1${\beta}$ in RAW 264.7 cells. Haedoksamultang inhibited NF-${\kappa}B$ activation in LPS-treated RAW 264.7 cells. Moreover, this compound blocked $I{\kappa}B-{\alpha}$ phosphorylation and nuclear translocation of the cytosolic NF-${\kappa}B$ p65 subunit, which highly correlated with the production and expression of inflammatory mediators. Results: Haedoksamultang suppresses that inflammation-associated gene expression by blocking NF-${\kappa}B$ activation. Conclusion: These results suggest that Haedoksamultang may be beneficial for treating inflammatory disease.
