Objectives : Allium hookeri is a well-known traditional herbal remedy and its root used for treatment of inflammation and tumor. However, the mechanism of anti-inflammatory effect of Allium hookeri is still unknown. This study aims to examine the mechanism of anti-inflammatory effect of Allium hookeri on mouse macrophage cell line, RAW 264.7 cells. Methods : Anti-oxidant effect of water extract of Allium hookeri (WEAH) was measured by 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay. 3- (4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay was performed to determine the effect of WEAH on cell viability in RAW 264.7 cells. In addition, anti-inflammatory effect of WEAH was investigated in RAW 264.7 cells. Inflammation of RAW 264.7 cells induced by lipopolysarccharide (LPS) treatment and expression levels of inflammatory cytokine interleukin 1 β (IL-1β) and interleukin 6 (IL-6) gene were analyzed using quantitative reverse transcription PCR (qRT-PCR) analysis. Furthermore, the phosphorylation of inhibitor of nuclear factor kappa B (IκBα) after LPS treatment with WEAH-treated RAW 264.7 cells was confirmed by immunoblot analysis. Results : WEAH showed a strong anti-oxidant effect and no cytotoxicity to RAW 264.7 cells up to 2 mg/㎖ concentration. The LPS-induced mRNA expression levels of IL-1β and IL-6 were decreased by WEAH treatment. Furthermore, the LPS-induced phosphorylation of IκBα is attenuated by WEAH treatment. Conclusions : Through experimental demonstration of anti-oxidant and anti-inflammatory effects of WEAH, we suggest that Allium hookeri is a valuable material for prevention and treatment of various inflammatory diseases.

As a part of ongoing research to elucidate and characterize antioxidant and anti-inflammatory nutraceuticals, solvent-partitioned fractions from Spergularia marina were tested for their ability to scavenge radicals and suppress inflammation. The results of the 2',7'-dichlorofluorescein diacetate assay indicate that solvent-partitioned fractions from S. marina scavenged intracellular radicals in $H_2O_2$-stimulated mouse macrophages. The tested fractions decreased the generation of nitric oxide (NO) and the expression of inflammation mediators, namely, inducible nitric oxide synthase (iNOS) and interleukin (IL)-6, by lipopolysaccharide (LPS)-induced mouse macrophages, indicating that S. marina decreases inflammation. Among all tested fractions [i.e., $H_2O$, n-buthanol (n-BuOH), 85% aqueous methanol (aq. MeOH), and n-hexane], the 85% aq. MeOH fraction showed the strongest antioxidant and anti-inflammatory response. The 85% aq. MeOH fraction scavenged 80% of the free radicals produced by $H_2O_2$-induced control cells. In addition, NO production was 98% lower in 85% aq. MeOH fraction-treated cells compared to LPS-induced control cells. The mRNA expression of iNOS and IL-6 was also suppressed in 85% aq. MeOH fraction-treated cells. The results of the current study suggest that the phenolic compound components of S. marina are responsible for its antioxidant and anti-inflammatory effects.

Dichloromethane, ethanol, and boiling water extracts of the brown alga Ecklonia cava were examined in vivo for their antipyretic, analgesic, and anti-inflammatory activities in mice. These activities were evaluated by yeast-induced pyrexia, tail-flick test, and phorbol myristate acetate-induced inflammation (edema, erythema, and blood flow). Ethanol extract of E. cava (0.4 mg/ear) inhibited the inflammatory symptoms of mouse ear edema, erythema, and blood flow by 82.6%, 69.0%, and 65.4%, respectively. This extract also demonstrated potent analgesic activity. No acute toxicity was observed after p.o. administration of each extract (5 g/kg bw). These in vivo data are in agreement with the claims of the health care industry and indigenous medicine that E. cava is an effective remedy for inflammation-related symptoms.

Sophorae Radix (SFR) is known as a therapeutic drug that has been used in Oriental traditional medicine for the treatment of skin and mucosal ulcers, gastrointestinal hemorrhage, diarrhea, inflammation and arrhythmia. In the present study, we examined the effects of the aqueous extract of SFR on anti-inflammation, anti-allergic and anti-oxidant effect in various cell lines; they include mouse lung fibroblast cells (hFCs), human mast cells (HMC-1), human monocytic cells (THP-1), and RAW 264.7 cells. Treatment with SFR extract at a concentration of 250 ${\mu}g$/ml for 24h showed no significant decrease in the survival rate of the hFCs. SFR decreased the mRNA expression of IL-8, TNF-$\alpha$, and IL-6 in HMC-1 cells. SFR extract treatment significantly inhi-bited the protein expression of IL-6 and, IL-8 induced by mite in THP-1 cells and it also did MCP-1 expression. We examined the alternation of histamine release in HMC-1 cells for investigating anti-allergic effect of SFR. Histamine secretion decreased after the treatment with SFR. In addition, SFR extract treatment at a concentration of 10 ${\mu}g$/ml, 100 ${\mu}g$ /ml, and 200 ${\mu}g$/ml lowered the $\beta$-hexosaminidase to 10.3%, 21.7%, and 50.8%, respectively. IC50 of SFR extract in RBL-2H3 cells was 196.85 ${\mu}g$/ml. Both activity of NF-$\kappa$B promoter in RBL-2H3 cells significantly diminished after the dose-dependent treatment of SFR. Therefore, our results indicate that SFR has anti-inflammatory and it may be useful for treating allergic diseases such as atopic dermatitis.

Objectives : The purpose of this study was to develop a simulator which can analyze the anti-inflammatory effects of medical herbs based on e-cell concerning p38 MAPK signal pathway. Methods : We collected data concerning medical herbs with anti-inflammatory effects and the active compounds to provide as a fundamental databse and to validate the newly developed algorithm. At this time, we used the target database as pubmed and gathered the data by data mining tool, pathway studio. Also we have developed the web-based search system for confirming database related to anti-inflammation. We researched the mechanism of actions of proteins in p38 MAPK signal pathway when active compound has been inserted into the network. We reduced total network into TAK-MKK3-p38 and made the two types of mathematical model about active compounds' interaction. Results & Conclusion : We constructed the database which have 69 cases of medical herbs, 71 cases of active compounds, about 8,000 cases of URL(Uniform Resource Locator) related to papers and reports. We designed the ordinary differential equations for response of TAK, MKK3, p38 in e-cell's cytosol and nucleus. We used this formular as measure whether an active compound of medicinal plants which is inputted by an user would have an anti-inflammation effects. We developed the visualization program which could show the change of concentration over time.

The systematic approach to pharmacologic treatment is typically to begin with the safest, simplest, and most conservative measures. It has been realized that the more rapidly inflammation is under control, the less likely it is that there will be permanent sequelae. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the mainstay of initial treatment for inflammation. In addition, the slow-acting antirheumatic drugs (SAARDs) and disease-modifying antirheumatic drugs (DMARDs) have efficacy of anti-inflammatory action in children with chronic arthritis. New therapeutic modalities for inflammation, such as etanercept and infliximab, promise even further improvements in the risk/benefit ratio of treatment. It is not typically possible at the onset of the disease to predict which children will recover and which will go on to have unremitting disease with lingering disability or enter adulthood with serious functional impairment. Therefore, the initial therapeutic approach must be vigorous in all children.

Ageing has been known to be deeply related to oxidative activities. Furthermore, inflammation is a response initiated by conditions such as infection and injury. It has been known that complex connections occur between oxidative stress and the inflammatory response, however underlying mechanism needs to be investigated. Chinese resource plants have been widely used as functional food and medicine for a long time, however it is not studied well how many of these resource plants work. We first decided testing anti-oxidant and anti-inflammatory activities with 95% ethanol extracts of the chinese resource plants, Boehmeria pilosinscula (Blume) Hassk., Carlemannia tetragona Hook f. and Clausena emarginata C.C.Huang. To measure anti-oxidant activity, we performed DPPH assay in Raw264.7 cells with 95% ethanol extracts. Clausena extracts showed significantly higher anti-oxidant activity than those of Boehmeria and Carlemannia. We then performed Nitric Oxide assay to measure the inflammation suppression levels with 95% ethanol extracts of these plants. Clausena extracts showed significantly higher suppression of nitric oxide production than those of Boehmeria and Carlemannia. This indicates that inflammation levels are significantly reduced by Clausena. After measuring anti-oxidant and anti-inflammatory activities, we then performed MTT assay to measure the cell survival rate of Raw264.7 cells treated with these extracts. Boehmeria showed much more cell survival rate than Carlemannia and Clausena. Taken together, this result suggests that Clausena extracts have more anti-oxidant and antiinflammatory activities than Boehmeria and Carlemannia, while Boehmeria extracts have more cell survival rate than Carlemannia and Clausena.

Objectives : Allergic diseases have a various symptoms of hyperresponsiveness and recently hyperresponsive reaction in the chronic phase is reported as the important mechanisms. Cheonggisan(CGS) is used in oriental clinics for curing various skin diseases due to effect of controlling of pruritus. There have been studies on the anti-allergic effect and anti-inflammatory effect of CGS, but there had no study of anti-allergic effects in allergic late inflammation of CGS, so we aimed to find out the effects of CGS in allergic late inflammation in our study.Methods : To investigate the anti-allergy effect and anti-inflammatory effect of CGS, RAW 264.7 macrophage cells and CSG water-extracts were used. Cytotoxic effect of CSG was examined by MTT assay, an oxidative product of NO was measured in the culture medium by the Griess reagent assay. The level of prostaglandin E2(PGE2) was measured by competitive enzyme-linked immunoassay. Cytokine(PGE2, IL-1β, IL-6, TNF-α) was measured by Bio-Plex suspension assay system and quantitative multiplexed cytokine/chemokine assay.Results : We investigated that there was no cytotoxic effect of CGS water-extract at any levels of concentration on RAW 264.7 macrophage cells by MTT assay. CGS water-extracts significantly suppressed the levels of the inflammatory mediators such as NO and PGE2, cytokine of IL-1β, TNF-α at the level of 400 ㎍/㎖ CGS concentration. But there was no significant effect on IL-6 production suppression.Conclusions : These results suggest that CSG water-extract has and anti-inflammatory effects in allergic reaction. These properties may contribute to the allergic diseases and inflammatory related disease care.
