Objectives : Categorized as 'cheongyeol' herbs, Herba Prunellae, Flos Lonicerae and Radix Scutellaria have been proven to have effect on degenerative brain disease, cerebrovascular disease and brain tumor because of their anti inflammation, antioxidant, or anticancer effects. In this study, we studied activity against reactive oxygen species and anti inflammation effect of these three 'Cheongyeol' herbs. Methods : We measured each herb's yield of ethanol extracts, phenolic contents and activities against DPPH, hydroxyl radical and superoxide anion. Also through 6-hydroxydopamine (6-OHDA) induced oxidative damage in SH-SY5Y human neuroblastoma cell line, we measured antioxidant effect and NO activity of the three herbs. From the three herbs, we chose Prunella Herba, which showed the highest antioxidant effect, and studied its cell survival rate and anti inflammation effect through COX-2 and iNOS. Results : All three herbs showed significant results, and especially Prunella Herba showed significant effect on phenol contents, antioxidant effect on various active oxygen and antioxidant, and anti inflammation effect through cell line. Conclusions : Further study of the origin concept of 'cheongyeol' and research into specific mechanisms and role in treatment of cranial nerve disease, seems warranted.

BACKGROUND/OBJECTIVES: Doenjang, Korean traditional fermented soybean paste has been reported to have an anti-obesity effect. Because adipose tissue is considered a major source of inflammatory signals, we investigated the protective effects of Doenjang and steamed soybean on oxidative stress and inflammation in adipose tissue of diet-induced obese mice. MATERIALS/METHODS: Male C57BL/6J mice were fed a low fat diet (LF), a high-fat diet (HF), or a high-fat containing Doenjang diet (DJ) or a high-fat containing steamed soybean diet (SS) for 11 weeks. RESULTS: Mice fed a DJ diet showed significantly lower body and adipose tissue weights than those in the HF group. Although no significant differences in adipocyte size and number were observed among the HF diet-fed groups, consumption of Doenjang alleviated the incidence of crown-like structures in adipose tissue. Consistently, we observed significantly reduced mRNA levels of oxidative stress markers (heme oxygenase-1 and $p40^{phox}$), pro-inflammatory adipokines (tumor necrosis factor alpha and macrophage chemoattractant protein-1), macrophage markers (CD68 and CD11c), and a fibrosis marker (transforming growth factor beta 1) by Doenjang consumption. Gene expression of anti-inflammatory adipokine, adiponectin was significantly induced in the DJ group and the SS group compared to the HF group. The anti-oxidative stress and anti-inflammatory effects observed in mice fed an SS diet were not as effective as those in mice fed a DJ diet, suggesting that the bioactive compounds produced during fermentation and aging may be involved in the observed health-beneficial effects of Doenjang. CONCLUSIONS: Doenjang alleviated oxidative stress and restored the dysregulated expression of adipokine genes caused by excess adiposity. Therefore, Doenjang may ameliorate systemic inflammation and oxidative stress in obesity via inhibition of inflammatory signals of adipose tissue.

Objectives : Nardostachys jatamansi (NJ) is a medicinal herb that has been reported in various traditional systems of medicine for its use in antispasmodic, a digestive stimulant, skin diseases. Previous studies have already reported that NJ effectively protects against inflammation. However, the active compound in NJ is unknown. Therefore, in the present study, we analyzed effects of a compound, 8α-hydroxy pinoresinol (HP), isolated from NJ against lipopolysaccharide (LPS) induced inflammation in RAW 264.7 cells.Methods : To examine the anti-inflammatory effect of HP against LPS, intraperitoneally pre-treat the HP (100, 200, 500 and 1,000 nM) 1 h prior to LPS challenges. LPS was stimulated with 500 ng/ml in RAW 264.7 cells. To identify the anti-inflammatory effect of HP, we measured inflammatory mediators such as inducible nitric oxide synthase (iNOS) and its derivative nitric oxide (NO), cyclooxygenase-2 (COX-2), prostaglandin E2 (PGE2). Also we evaluated molecular mechanisms including mitogen-activated protein kinases (MAPKs) and nuclear factor-kappaB (NF-κB) activation by western blot.Results : The HP inhibited production of inflammatory mediators, such as iNOS and its derivative NO, COX-2 and PGE2 in LPS- induced inflammationin RAW 264.7 cells. Additionally, HP also inhibited activation of p38 pathway signaling but not extracellularsignal-regulatedkinase (ERK), c-jun NH2-terminal kinase (JNK), and NF-κB.Conclusion : Our results suggest that HP has anti-inflammatory functions through the dephosphorylation of p38 and HP can provide beneficial strategy for prevention and therapy of inflammation.

Objectives : Portulaca oleracea (PO) have been used as a traditional medicine to treat inflammatory diseases in Korea. However, the anti-inflammatory effect of PO ethanol extract on lipopolysaccharide (LPS)-induced inflammation is not well-known. Therefore, this study was performed to identify the anti-inflammatory effect of PO on LPS induced inflammatory.Methods : Identification of PO was conducted by comparison with purified standards by HPLC. To measure out the cytotoxicity of PO, author performed the MTT assay. To evaluate the anti-inflammatory effects of PO, author examined the inflammatory mediators such as nitric oxide (NO) and pro-inflammatory cytokines (tumor necrosis factor (TNF)-α, interleukin, (IL)-1β and IL-6) on RAW 264.7 cells. Author also examined molecular mechanisms such as mitogen-activated protein kinases (MAPKs) and nuclear factor-B (NF-κB) activation by western blot.Results : Three major components (peaks 1, 2, 3) were detected in both varieties and peak 1 was characterized as caffeic acid, peak 2 as p-coumaric acid, and peak 3 as ferulic acid by comparison of chromatographic properties with authentic standards. Extract from PO itself did not have any cytotoxic effect in RAW 264.7 cells. PO inhibited LPS-induced productions of inflammatory mediators such as NO and pro-inflammatory cytokines in RAW 264.7cells. In addition, PO inhibited the phosphorylation of extracellular signal-regulated kinase1/2 (ERK1/2), c-Jun NH₂-terminal kinase (JNK) and NF-κB activation in RAW 264.7 cells.Conclusions : Above experiment data can be an important indicator for the identification of PO and this study suggest that treatment of PO could reduce the LPS-induced inflammation. Thereby, PO could be used as a protective agent against inflammation.

DA-9601 is an extract obtained from Artemisia asiatica, which has been reported to have anti-inflammatory effects on gastrointestinal lesions; however, its possible anti-inflammatory effects on the small intestine have not been studied yet. Therefore, in this study, we investigated the protective effects of DA-9601 against the ACF-induced small intestinal inflammation. Inflammation of the small intestine was confirmed by histological studies and the changes in the CD4⁺ T cell fraction induced by the inflammation-related cytokines, and the inflammatory reactions were analyzed. Multifocal discrete small necrotic ulcers with intervening normal mucosa were frequently observed after treatment with ACF. The expression of IL-6, IL-17, and TNF-α genes was increased in the ACF group; however, it was found to have been significantly decreased in the DA-9601 treated group. In addition, DA-9601 significantly decreased the levels of proinflammatory mediators such as IL-1β, GM-CSF, IFN-γ, and TNF-α; the anti-inflammatory cytokine IL-10, on the other hand, was observed to have increased. It is known that inflammatory mediators related to T cell imbalance and dysfunction continuously activate the inflammatory response, causing chronic tissue damage. The fractions of IFN-γ⁺ Th1 cells, IL-4⁺ Th2 cells, IL-9⁺ Th9 cells, IL-17⁺ Th17 cells, and Foxp3⁺ Treg cells were significantly decreased upon DA-9601 treatment. These data suggest that the inflammatory response induced by ACF is reduced by DA-9601 via lowering of the expression of genes encoding the inflammatory cytokines and the concentration of inflammatory mediators. Furthermore, DA-9601 inhibited the acute inflammatory response mediated by T cells, resulting in an improvement in ACF-induced enteritis.

Purpose : The purpose of this study was to examine the anti-inflammatory effects of Sparassis crispa (SC). SC is a well-known traditional herbal remedy and its mushroom is used for treatment of inflammation. Many diseases that are increasing recently have characteristics of inflammatory diseases. Researchers are finding bioactive substances from natural products that can promote treatment and prevention of inflammation. We investigated the effect of water extracted from SC on the expression of effector genes involved in the function of RAW 264.7 cells. Methods : Effects of RAW 264.7 cells on cell viability, antioxidation, and mRNA expression were examined using water extracts from SC. A 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay was performed to determine the effect of water extracts from SC on cell viability in RAW 264.7 cells. Inflammation of RAW 264.7 cells induced by lipopolysaccharide (LPS) treatment and expression levels of inflammatory cytokine TNF-α, iNOS and IL-1β gene were analyzed using quantitative reverse transcription PCR (qRT-PCR) analysis. Results : The MTS assay was performed on RAW 264.7 cells after treatment with various concentrations of water extracts of SC. Treatment of RAW 264.7 cells with water extracts from SC and LPS at a concentration of 0.125, 0.5 mg/㎖ for twenty four hours promoted mRNA expression of TNF-α, iNOS and IL-1β. Conclusion : MTS assay was applied to RAW 264.7 cells after various concentrations of water extracts of SC. Through experimental demonstration of anti-oxidant and anti-inflammatory effects of water extracts from SC, we suggest that SC is a valuable material for the prevention and treatment of various inflammatory diseases.

Phallus impudicus var. impudicus L. is an edible mushroom that has long been used as folk medicine in China. The aim of this study was to evaluate the antioxidant, anti-cholinesterase, and inflammation inhibitory activities of a methanol extract of fruiting bodies of P. impudicus var. impudicus L. The extract exhibited good 1,1-diphenyl-2-picrylhydrazyl scavenging activity, excellent ferrous ion chelating activity, and moderate hydroxyl radical scavenging activity compared with BHT at 2.0 mg/ml. However, the reducing power of the extract was significantly lower than that the BHT positive control. Although the inhibitory activities of methanol extract on acetylcholinesterase and butyryl cholinesterase were significantly lower than the galanthamine positive control at the concentration tested, the inhibition of acetylcholinesterase and butyryl cholinesterase was 52.83% and 55.17%, respectively, at 1.0 mg/ml. The methanol extract also demonstrated excellent inhibition of inflammation-related activities, such as production of nitric oxide in lipopolysaccharide-induced RAW 264.7 macrophage cells and acute edema induced by administration of carrageenan on the hind paw of rats. The collective results suggest that the fruiting body of P. impudicus var. impudicus L. might be a good source of antioxidant, anti-cholinesterase, and anti-inflammation compounds.

Objectives : The acupuncture has been in the classic arsenal of Oriental medicine over inflammatory diseases. Its physiological mechanism is not fully understood but being known better everyday. We reviewed several papers to describe current concepts over anti-inflammatory mechanism of acupuncture. Methods : Some computerized literature searches were done using the key words of 'acupuncture' AND 'Anti-inflammatory' in Medline via Pubmed between March 2007 and December 2007. Only rationally-designed studies were picked among practically associated materials. A well-known hypothesis on acupunctural physiology was adapted for integration. Result : 18 studies were selected. 17 studies were laboratory experiment and 1 was a clinical study. Data was classified into some comprehensive categories. Author's opinion was added at the end of each category. Study results supported the hypotheses on acupunctural physiology; Acupuncture has some influences on autonomic nerve system(ANS). And it stimulates several receptors from target cells like macrophage, and finally inhbits cytokines like TNF-${\alpha}$, IL-1${\beta}$ andIL-10 which are inflammation-mediated. Acupuncture increases the opioid releasing therefore relieves inflammation. And acupuncture inhibits cyclooxgenase(COX) but its mechanism is controversial until now. Conclusion : Current concepts over anti-inflammatory mechanism of acupuncture are as follows. Acupucture suppresses inflammation by stimulation of ANS, increasing of opioid releasing and inhibition of COX. But more studies are needed to fully describe the anti-inflammatory effect of acupuncture.

Purpose: This study was performed to evaluate anti-inflammatory effects of Hyulbuchukeotanggamibang water extract (HBCT). Methods: In the study of anti-inflammatory effects, HBCT was investigated using cultured cells and a murine models. As for the parameters of inflammation, levels of several inflammatory cytokines and chemical mediators which are known to be related to inflammation were determined in mouse lung fibroblast cells (mLFCs) and RAW264.7 cells. Results: Prior to the experiment, we investigated the cytotoxicity of HBCT. HBCT showed a safety in cytotoxicity on mLFCs. In experiment of anti-inflammatory effect, HBCT effected scavenging activity on DPPH free radical, superoxide dismutase and superoxide anion radical. HBCT inhibited $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, COX-2 and NOS-II mRNA expression in a concentration-dependent manner in RAW264.7 cell line, and inhibited significantly $IL-1{\beta}$, IL-6, $TNF-{\alpha}$ production at $100{\mu}g/\;ml$ in a concentration-dependent manner. Conclusion: These results suggest that HBCT can be used for treating diverse female diseases caused by inflammation such as endometriosis, pelvic pain, cervicitis, pelvic inflammatory disease and pelvic tuberculosis and so forth.
