Objectives : Thymus quinquecistatus var. japonica (H.Hara) is a member of the genus Thymus of perennial aromatic herb, and it's designated as a natural monument of South Korea. It has traditionally been known to have protective or therapeutic effects on various human disease including cerebrovascular and neurological disease. Recently it was suggested that essential oil extracted from thyme has anti-fungal and anti-bacterial effect. The aim of this study is to investigate anti-inflammatory effect of Thymus quinquecistatus var. japonica in Raw 264.7 macrophage cell line. Methods : The cytotoxic effects of water and 70% ethanol extracts from Thymus quinquecistatus var. japonica, was tested using MTT assay. Inhibitory effects of the extracts to nitric oxide production and mRNA expression of inflammatory cytokines were examined by RT-PCR. Also, MitoSOX-red assay and JC-1 assay were performed to determine if the extracts can inhibit mitochondrial ROS accumulation and maintain mitochondrial membrane potential. Results : In LPS-induced inflammatory response, the extracts efficiently reduced nitric oxide NO production through inhibiting mRNA expression of iNOS enzyme. In addition, expression of the proinflammatory cytokines, IL-1𝛽 and IL-6, was also down-regulated by the extract treatments. Excessive accumulation of mitochondrial ROS induced by LPS was inhibited in the extract treated cells, which finally protected mitochondrial membrane potential. Conclusions : These results showed that water and 70% ethanol extracts from Thymus quinquecistatus var. japonica have anti-inflammatory effect through down regulation of IL-1𝛽, IL-6, and iNOS, and also have antioxidative effect against mitochondrial ROS accumulation that promote inflammatory response.

It is well known that the fruit of the vitamin tree (Hippophae rhamnoides L.) provides excellent anti-diabetic, antibacterial, immune regulation, anti-inflammatory, and anti-aging effects. In some countries including Europe the fruit has been added to certain foods to develop functional foods. The present research was carried out to elucidate the biological function of vitamin tree fruit powder added to fermented milk. It was found that there was an antioxidant effect of yoghurt made with vitamin tree fruit powder, and this effect was greater with increased incubation time and amount of vitamin powder, as shown by 1,1-diphenyl2-picrylhydrazyl (DPPH) and 2,2-anziobis (3-ehtylbenzothiazoline-6-sulfonic aicd) (ABTS) radical scavenging activities. The antibacterial effect of yoghurt containing vitamin tree fruit powder was shown to be effective against four pathogenic microorganisms, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Salmonela Typhimurium. In particular, yoghurt supplemented with 5% of vitamin tree fruit powder showed the best antibacterial effect. The yogurt containing the vitamin tree fruit powder significantly inhibited the expression of the anti-inflammatory cytokines interleukin (IL)-6 (yogurt [Y] + Hippophae rhamnoides L. powder [HP] and yogurt containing 5% Hippophae rhamnoides L. powder [HPY]) and IL-1β (HP, Y + HP and HPY) in a concentration-dependent manner among tumor necrosis factor (TNF)-α, IL-6, IL-1, and induced nitric oxide synthase (iNOS). Our results clearly demonstrated that vitamin tree fruit powder could be a good functional ingredient for improving health through yoghurt manufactured with vitamin tree.

This study was carried out to investigate the anti-oxidative and anti-inflammatory effects of hot water extracts of Ligularia fischeri cultivated in Youngyanggun. We obtained hot water extract (HWE) and cold water extract (CWE) from L. fischeri. The anti-oxidative activities of L. fischeri extracts were measured by 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity. The anti-inflammatory effects of L. fischeri were evaluated in human mast cell line-1 (HMC-1) cells stimulated with phorbol-12-myristate-13-acetate plus A23187 (PMACI). The solid yields of HWE was 150% higher than CWE solid yield. Total polyphenol contents of HWE were $198.07{\pm}0.24mg/g$. The value of anti-oxidative activities of HWE were shown $IC_{50}$ $28.2{\pm}0.04ug/mL$. We showed that HWE significantly reduced the PMACI-induced the production of IL-6 (0.01-1 mg/mL), IL-8 (0.1-1 mg/mL), and $TNF-{\alpha}$ (0.01-1 mg/mL). These results indicate that the HWE of L. fischeri can be used as a functional material due to its antioxidant and anti-inflammatory activities.

The present study was to investigate anti-oxidative and anti-inflammatory activity of Perillae semen in RBL-2H3 basophilic leukemia cells. Inhibitory effect of Perillae semen onto free radical generation was determined by measuring DPPH and hydroxyl radical scavenging activities in vitro. Anti-inflammatory actions of Perillae semen extracts (100, 250, $500\;{\mu}g/mL$) were assessed by testing their effects on the degranulation of mast cells. For this, $\beta$-hexosaminidase released from RBL-2H3 cells was used and proinflammatory cytokines were measured by an ELISA kit. Our results indicated that Perillae semen water extracts effectively inhibited free radical generation. At the concentration of $500\;{\mu}g/mL$ of water extract, the degranulation of RBL-2H3 cells were inhibited by 42.1%. The IgE-antigen complex increased the accumulation of IL-4 and TNF-$\alpha$ secretion in RBL-2H3 cells and treatments with 250 and $500\;{\mu}g/mL$ of Perillae semen extracts suppressed the IgE induced secretion of IL-4 and TNF-$\alpha$ protein by 20.5, 26.9% and 14.5, 16.5% respectively. We observed that Perillae semen water extract reduced $\beta$-hexosaminidase, IL-4, and TNF-$\alpha$ secretion in RBL-2H3 cells. These results provide that Perillae semen may be beneficial in the treatment of allergic inflammatory disease.

Mulberry tree twigs (Ramulus mori) contain large amounts of oxyresveratrols and have traditionally been used as herbal medicines because of their anti-inflammatory properties. However, the signaling mechanism by which R. mori exerts its anti-inflammatory action remains to be elucidated. In this study, we observed that R. mori ethanol extracts (RME) exerted an inhibitory effect on the lipopolysaccharide (LPS)-induced production of the pro-inflammatory cytokine interleukin-6 (IL-6) in Raw264.7 macrophage cells. Additionally, RME inhibited IL-6 production by blocking the leukotriene B₄ receptor-2 (BLT2)-dependent-NADPH oxidase 1 (NOX1)-reactive oxygen species (ROS) cascade, leading to anti-inflammatory activity. Finally, RME suppressed the production of the BLT2 ligands LTB4 and 12(S)-HETE by inhibiting the p38 kinase-cytosolic phospholipase A₂-5-/12-lipoxygenase cascade in LPS-stimulated Raw264.7 cells. Overall, our results suggest that RME inhibits the 'BLT2 ligand-BLT2'-linked autocrine inflammatory axis, and that this BLT2-linked cascade is one of the targets of the anti-inflammatory action of R. mori.

The aim of the convergence study is to evaluate anti-asthma effects of white ginseng complex extract(WGCE) on OVA-induced allergic asthma in mice. WGCE was administered at 100 mg/kg and 300 mg/kg to mice, where asthma was induced by OVA. Th2 cytokine including IL-4, IL-5 and IL-13 were measured by Luminex. Also, OVA-IgE and eosinophil were measured by haemocytometer and BALF total cells were measured microscope. Production of IL-4, IL-5, IL-13 and OVA-IgE in serum was decreased, respectively, in comparison with control. The eosinophil in whole blood decreased significantly. In addition, WGCE groups showed a decrease in the BALF total cells. These results demonstrated that WGCE decreases the Th2 cytokine and asthma factors. Therefore, we strongly suggest that WGCE could be effectively used as a therapeutic drug based on its anti asthma factors.

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.

Objectives : To clarify the possible effect of JS (Juglans sinensis), PCF (Psoralea corylifolia L.), and J+P(JS+PCF), we examined their influence on the development of pulmonary eosinophilic inflammation in the asthmatic murine model. Methods : All mice were immunized on two different days (21 days and 7 days before inhalational exposure) by intraperitonial injections of 0.2 ml alum-precipitated Ag containing 100 ${\mu}$g of OVA bound to 4 mg of aluminum hydroxide in PBS. Seven days after the second sensitization, mice were exposed to aerosolized ovalbumin for 30 minutes/day on 3 days/week for 8 weeks (at a flow rate of 250 L/min, 2.5% ovalbumin in normal saline) and, JS, PCF and J+P (200 mg/kg, 400 mg/kg) were orally administered 3 times per week for 8 weeks. Results : The suppressive effects of JS, PCF, and J+P were demonstrated by the accumulation of eosinophils into airways, with the reduction of eosinophils and lung leukocytes. These were correlated with the marked reduction of IL-4, IL-5, IL-13 levels in the BALF and serum. OVA-specific IgE levels were also decreased in serum and BAL from these mice. And also JS, PCF, and J+P decreased eosinophilic CCR3 and CD11b expression in lung tissue. Conclusions : These results indicate that JS, PCF, and J+P have deep inhibitory effects on airway inflammation and hyper-responsiveness in the asthmatic murine model. The suppression of IL-5, IgE, and eosinophilils and the increase of IFN-${\gamma}$ production in BALF seem to contribute to these effects. Specially, esosinophils and TNF-a in J+P combination group were significantly reduced in BALF and lung tissue. Hence, the results indicated that JS, PCF, and J+P could act as an immuno-modulator which possesses anti-inflammatory and anti-asthmatic property by modulating the imbalance between Th1 and Th2 cytokines.
