Solanum melongena L. (Solanaceae) has anti-oxidant, analgesic, and hypolipidemic effects. We previously showed that Solanum melongena (SM) aqueous extract inhibits mast cell-mediated allergic reactions. The activation of protease-activated receptor-2 (PAR-2) induces acute inflammation in rat hindpaw. In the present study, we investigated the effects of the SM aqueous extract on mouse paw edema induced by PAR2 agonists. Trypsin or trans-cinnamoyl-LIGRLO-NH$_2$ (tc-NH$_2$), PAR-2 agonists, was injected into the hind paw of mice to induce paw edema. SM aqueous extract (1, 5, 10, and 100 mg/kg) was orally administered 1 hr before induction of paw edema. SM aqueous extract (5, 10, and 100 mg/kg) significantly inhibited both paw edema and vascular permeability in the dose-dependent manner. Furthermore, SM aqueous extract (10 mg/kg) significantly inhibited PAR-2 agonist-induced myeloperoxidase (MPO) activity and tumor necrosis factor (TNF)-$\alpha$ expression in paw tissue compared to that of saline. These results suggest that SM aqueous extract may be useful for treatment of PAR-2-mediated inflammation.

This study was to evaluate the effect of Yeongyupaedog-san (YGPDS) on mouse Thl and Th2 cells' differentiation and ovalbumin (OVA)-induced allergic inflammation. The proliferation of mouse CD4 T cells and the secretion of Th1/Th2 cytokines under the influence of YGPDS extract were measured as well as the amount of ${\beta}-hexosaminidase$ in RBL-2H3 cells and the levels of $TNF-{\alpha}$ and 1L-6 secretion in Raw264.7 cells. BALB/c mice were orally administered with YGPDS extract and simultaneously inoculated with OVA to induce allergic reaction and measure the level of total IgE, OVA-specific IgE and the production of IFN- g, IL-4, IL-5 by the spleen cells. When mouse CD4 T cell were stimulated with anti-CD3 and anti-CD28 for 48 hours in various concentrations of YGPDS extract, it increased proliferation of CD4 cells by 11% in $100\;{\mu}g/^{ml}$ concentration but it showed an inhibition by 37% at $200\;{\mu}g/^{ml}$ CD4 T cells under Th1/Th2 polarizing conditions for 3 days with YGPDS resulted in mild decrease of IFN- g in Thl cells and significant decrease of IL-4 in Th2 cells at $500\;{\mu}g/^{ml}\;and\;100\;{\mu}g/^{ml}$ by 18% and 21%, respectively. YGPDS extract had a dose-dependent inhibitory effect on antigen-induced release of ${\beta}-hexosaminidase$ in RBL-2H3 cells. Treatment of YGPDS extract on LPS stimulated Raw 264.7 cells showed dose-dependent decrease in TNF-n production. Oral administration of YGPDS extract on OVA-induced allergic mice showed an inhibitory effect on the levels of total serum IgE and OVA-specific IgE by 25% and 34% , respectively. Culture of spleen cells with OVA resulted in significant increase of IFN- g by 44% and significant decrease of IL-4 and IL-5 by 56%, and 24%, respectively. The results show that YGPDS does not strongly induce mouse T cells to transform into Thl or Th2 but it has an anti-allergic effect in vitro, and that it also corrects the unbalance between the reactions of Th cells in allergic diseases.

This study was to evaluate the effect of Bulhwangeumjeonggi-san (BS) on mouse Th1 and Th2 cells' differentiation and ovalbumin (OVA)-induced allergic inflammation. The proliferation of mouse CD4 T cells and the secretion of Th1/Th2 cytokines under the influence of BS extract were measured as well as the amount ${\beta}$-hexosaminidase in RBL-wH3 cells and the levels of TNF-${\alpha}$ and IL-6 secretion in Raw264.7 cells. BALB/c mice were orally administered with BS extract and simultaneously inoculated with OVA to induce allergic reaction and measure the level of total lgE, OVA-specific lgE and the production of IFN- g, IL-4, IL-5 by the spleen cells. When mouse CD4- T cell were stimulated with anti-CD3 and anti-CD28 for 48 hours in various concentrations of BS extract, it increased proliferation of CD4 cells by 14% in 50 ${\mu}g/m{\ell}$ concentration but it showed an inhibition in higher concentrations. CD4 T cells under Th1/Th2 polarizing conditions for 3 days with BS resulted in mild decrease of IFN- g in Th1 cells and mild increase of IL-4 in Th2 cell at 50 ${\mu}g/m{\ell}$ but the level of IL-4 decreased by 18% at 100 ${\mu}g/m{\ell}$. BS extract had a dose-dependent inhibitory effect on antigen-induced release of ${\beta}$-hexosaminidase in RBL-2H3 cells. Treatment of BS extract on LPS stimulated Raw 264.7 cells showed dose-dependent decrease in TNF-${\alpha}$ production. Oral administration of BS extract on OVA-induced allergic mice showed an inhibitory effect on the levels of total serum lgE and OVA-specific lgE by 50% and 55%, respectively. Culture of spleen cells with OVA resulted in significant increase of IFN- g by 25% and significant decrease of IL-4 and IL-5 by 53%, and 38%, respectively. The results show that BS does not strongly induce mouse T cells to transform into Th1 or Th2 but it has an anti-allergic effect in vitro, and that it also corrects the unbalance between the reactions of Th cells in allergic diseases.

It is recognized that Perilla frutescens L. (PfL) are useful for various diseases, including allergic disorders. To evaluate whether the PfL extract have potential in alleviating oxidant and inflammatory process, some in vitro antioxidant assays and in vivo DNFB-induced atopic assay were investigated. Extracts of PfL have potent anti-oxidant activity by DPPH or FRAP assay. By treatment of high temperature / high pressure extraction process of PfL seed, the activity was increased. Using a mouse animal model, we found that PfL extract reduces ear thickness and epithelial thickening and infiltration of immune cells inhibition. Collectively, the present results suggest that PfL can be used as an antioxidant and/or anti-inflammatory biomaterial, that should be proved to evaluate on mechanistic study and development of functional food.

Cyanidin 3 - rutinoside chloride (CRC) is major anthocyanin, found in Schisandra chinensis, is known to have antioxidant, anticancer, anti-inflammatory, tonic, and anti-aging effects in Korea, China and Japan. In the present study, the human mast cell line (HMC-1) was used to investigate the effects on the production of pro-inflammatory mediators. In this study, CRC showed no cytotoxicity in HMC-1. CRC significantly inhibited the secretion of inflammatory cytokines such as tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-6 in PMA plus A23187 cacium ionophore (PMACI)-stimulated HMC-1 cells. In addition, CRC suppressed the serum levels of IgE. Furthermore, CRC decreased the PMACI- stimulated phosphorylation of mitogen activated protein kinases (MAPKs) such as p-ERK, p- JNK and p-P38. These results indicate that the pharmacological actions of CRC suggest their potential activity for treatment of allergic inflammation through the down-regulation of mast cell activation.

The seeds of Raphanus sativus L. (RSL) and Phaseolus calcaratus Roxburgh (PHCR), the root of Scutellaria baicalensis (SB), and the flower of Lonicera japonica (LJ) have been traditionally used as herbal medicines for anti-inflammation. Unlike the SB and LJ, little information is available for the scientific bases that show the anti-inflammatory mechanisms of RSL and PHCR. In this study, we prepared boiled water extracts from the medicines and determined their potentials in inhibiting nitric oxide (NO) production, cyclooxygenase-2 (COX-2) expression, and tumor necrosis factor (TNF)-$\alpha$ and interleukin (IL)-6 secretion in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. The effects of the medicines on serum IgE levels in ovalbumin (OVA)-administrated mice were also studied. The medicines inhibited production of TNF-$\alpha$ and IL-6, and COX-2 expression in LPSstimulated macrophages. Especially, PHCR water extract showed more potent inhibition on TNF-$\alpha$ production than SB and LJ extracts, but RSL extract did not exert these effects. Similar to the cases of SB and LJ, PHCR extract prevented the phosphorylation of $I{\kappa}B{\alpha}$ and c-Jun, and the activation of NF-${\kappa}B$-DNA binding. Further, oral supplementation of PHCR extract attenuated significantly serum levels of total and OVA-specific IgE in OVAtreated animals. These results suggest a possibility that PHCR water extract can be used for the treatment of inflammatory and allergic diseases.

The anti-inflammatory effect of brown alga Ecklonia cava is well known, and several phlorotannins have also been reported. In this study, major active components for anti-allergy and anti-inflammation were identified by NMR and MS analysis, and the levels of effectiveness were compared. Six major phlorotannins-phloroglucinol, eckol, eckstolonol, triphlorethol-A, phlorofucofuroeckol A, and dieckol-were isolated from the ethyl acetate fraction of E. cava. In order to analyze the major active substances in E. cava, antioxidant, anti-inflammatory, and anti-allergic effects were evaluated for the six separate substances. Antioxidant capacities of each phlorotannin were evaluated using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radicals, where phlorofucofuroeckol A and triphlorethol-A had the highest radical scavenging capacity in respective radical scavenging assays. Phlorofucofuroeckol A exhibited the highest inhibition of nitric oxide production in LPS-stimulated RAW 264.7 cells among phlorotannins tested. Dieckol inhibited the release of ${\beta}-hexosaminidase$, a marker for the release of histamine in mast cells, in a dose-dependent manner in antigen-stimulated RBL-2H3 mast cells. Additionally, no cytotoxicities were observed at 1 and $2{\mu}g/ml$ in both phlorofucofuroeckol A and dieckol. These results suggest that phlorofucofuroeckol A and dieckol may play a key role in allergic inflammatory reactions.

Objectives The purpose of this study is to investigate the effects of Gardenia jasminoides for. grandiflora extracts' (GAJ) anti-inflammatory effect on RBL-2H3 mast cells and OVA/alum-sensitized mice. Methods In this study, IL-4 and IL-13 production was measured via ELISA analysis, and mRNA expressions of GM-CSF, IL-4, IL-5, $TNF-{\alpha}$, IL-6 were analyzed by real-time PCR. In addition, MAPKs and $NF-{\kappa}B$ p65 transcription factors were examined using western blotting, and ELISA was used to understand IgE, IL-4, and IL-13 production in ovalbumin-allergic mice in in vitro study. Results As a result of this study, 1. GAJ were observed to suppress the mRNA expression of GM-CSF, IL-4, IL-13, IL-5, $TNF-{\alpha}$, IL-6 in comparison to PMA 50 ng/ml, ionomycin $0.5{\mu}M$ (PI) control group. 2. GAJ also inhibited the IL-4, IL-13 production in comparison to PI control group. 3. Western blot analysis showed decrease on the expression of mast-cell-specific transcription factors, including MAKPs (ERK, JNK, p38) and $NF-{\kappa}B$ p65. 4. Orally-administered GAJ group in OVA/alum induced Balb/c mice showed decreased level of OVA-specific IgE in the serum. This group also has shown decreased the level of IL-4, IL-13 in the splenocyte culture supernatant. Conclusions Obtained results suggest that GAJ may regulate the allergic inflammation by transcription factors MAKPs (ERK, JNK, p38) and $NF-{\kappa}B$ p65 causing inhibition of Th2 cytokines in mast cells and OVA/alum-sensitized mice.

Nypa fruticans wurmb (NF) has been used as traditional medicinal food in Asian countries. Especially, NF has been used for conventional medicine to treat inflammatory periodontal diseases. Previous studies have been shown that NF has large amount of useful constituents such as phenolic acids, polyphenols and flavonoids. Also, NF is known as having medicinal effects such as anti-oxidant, anti-inflammatory and cholesterol-lowering effects. NF has recently been attracted to use complementary medicinal food on inflammatory diseases in Korea. However, there are no obvious effects in inflammatory and metabolic diseases also mechanisms has been studied yet. The purpose of this study was to investigate the anti-inflammatory effects of NF and steamed-NF (SNF), which recently has been used as health food, using Human keratinocyte cell line (HaCaT) and Human mast cell line (HMC-1). The cytotoxicities of NF and SNF were measured by using MTT assays in HaCaT cells and HMC-1 cell. To evaluate anti-inflammatory effects of NF and SNF, HaCaT cells were stimulated with tumor necrosis factor $(TNF)-{\alpha}$ and Interferon $(IFN)-{\gamma}$. Also, HMC-1 cells were stimulated with phorbol-12-myristate-13-acetate (PMA) and A23187 calcium ionophore (A23187) to induce allergic inflammation. Inflammatory cytokine were measured by enzyme-linked immunosorbent assay (ELISA). In this result, the extract of NF and SNF (0.01 - 1mg/ml) did not show cytotoxicity in HaCaT cells and HMC-1 cells. In addition, the NF and SNF suppressed the production of interleukin (IL)-6 and IL-8 in HaCaT cells at highest concentration. Furthermore, the treatment of SNF significantly inhibited the secretion level of IL-8 in PMA plus A23187-stimulated HMC-1 cells compared with NF treatment group. These results suggest that the extract of NF and SNF may serve as a potential therapy for skin inflammatory diseases.
