Ginseng (the root of Panax ginseng Meyer) fermented by Lactobacillus plantarum has been found to attenuate allergic responses in in vitro and in vivo experimental models. Ginseng has been reported to also possess various biological functions including anti-inflammatory activity. The present study was aimed at comparing the anti-allergic effect of ginseng and fermented ginseng extracts on IgE-mediated passive cutaneous anaphylaxis in vitro in a murine cell line and in vivo in mice. Fermented ginseng extract (FPG) showed higher inhibitory effect against in vitro and in vivo allergic responses when compared with ginseng extract (PG). The secretion of ${\beta}$-hexosaminidase and interleukin (IL)-4 from the IgE-DNP-stimulated RBH-2H3 mast cells were significantly (p < 0.05) inhibited by FPG treatment, and this effect was concentration-dependent. Further, MKK4 activation and subsequent JNK phosphorylation were attenuated by FPG treatment. The inhibitory effect of FPG on the in vitro allergic response was verified in vivo against IgE-DNP-induced passive cutaneous anaphylaxis in a mouse model. These data indicated that the fermentation of ginseng with L. plantarum enhanced its anti-allergic effects both in vitro and in vivo. We predict that compositional changes in the ginsenosides caused by the fermentation may contribute to the change in the anti-allergic effects of ginseng. The results of our study highlight the potential of the use of FPG as a potential anti-allergic agent.

Samul-Tang (SMT) has been used for nourishing of the blood, hematopoiesis as a herbal medicine history. The purpose of this study is to find out anti-allergic inflammatory reaction of SMT. To clarify the mechanism, the effect of SMT on vascular permeability of rat cutaneous tissue and histamine and cytokines (IL-6, IL-8, TNF-${\alpha}$) release from mast cells were observed. The results are the pretreatment with SMT significantly decreased the compound 48/80-induced degranulation and histamine release from RPMC, SMT also inhibited the anti-DNP lgE-induced increment of vascular permeability of rat cutaneous tissue. SMT significantly reduced the PMA plus A23187-induced increment of expression of IL-6, IL-8, and TNF-${\alpha}$ in HMC-1 Cell. The Present study provide evidence that SMT inhibits mast cell-derived inflammatory allergic reactions by blocking histamine release and pro-inflammatory cytokine expression, and suggest the mechanisms of action. Furthermore, in vivo and in vitro anti-allergic effect of SMT suggests a possible therapeutic application of this agent in inflammatory allergic diseases.

Objective : Allergic disease, a very common chronic illness that affects all ages of patients, has been well characterized as an IgE-dependent immunologic response. Recently, interest has grown about the late inflammatory reaction as well as the early one characterized by IgE and mast cells in allergic disease. The purpose of this study was to find the anti-inflammatory effect of Taeeumjowui-tang (Taiyintiaowei-tang) in allergic reaction. Methods : The experiment was performed using Raw 264.7 cells pretreated with Taeeumjowui-tang contents extracts. The results were measured for different concentrations of Taeeumjowui-tang extracts (100, 200, $300{\mu}g$/ml): the toxicity and proliferation of cells by MTT analysis, LPS-induced NO production using Griess reagent and IL-6/ TNF-${\alpha}$ production, which is a significant criteria for diagnosing allergic reaction. Results : No toxicity of Taeeumjowui-tang (100, 200, $300{\mu}g$/ml) on Raw 264.7 cells was found after 24 hours incubation. LPS-induced NO production was reduced after treatment with Taeeumjowui-tang (100, 200, $300{\mu}g$/ml)(P<0.001). IL-6 decreased only at $100{\mu}g$/ml(P<0.05). TNF-${\alpha}$ production decreased only at $300{\mu}g$/ml, but still statistically insignificant. There was no relationship between any components of Taeeumjowui-tang alone and inhibition of NO production. Conclusions : These data suggest that Taeeumjowui-tang has anti-inflammatory effects in allergic reaction.

Objectives : The root of Codonopsis pilosula (Fr.) Nannf. (Codonopsis Pilosulae Radix) has been traditionally used as a oriental medicine with an anti-thrombotic, antidiabetic, anticancer, and anti-gastric ulcer effects and immunological adjuvant. In this study, we investigated the effect of 70% ethanol extract of Codonopsis Pilosulae Radix (CPR-E) on ovalbumin (OVA)-induced allergic responses in mice. Methods : Mice were sensitized (1, 8, and 15 days) with OVA and airway challenged(22, 24, 26, 28, and 30 days) to induced allergic responses. CPR-E extract at doses of 50 and 100 mg/kg/body weight was orally administered from days 21 to 30 consecutively. The levels of allergic mediators such as histamine, OVA-specific immunoglobulin (Ig) E, and Th1/Th2 cytokines such as IFN-${\gamma}$ and IL-4 were measured in the sera of mice by ELISA. The histological change of lung tissue was observed by hematoxylin and eosin (H&E) staining. Results : CPR-E extract significantly decreased the serum levels of histamine, OVA-specific IgE, and IL-4 compared with those of OVA control group, but significantly increased the serum level of IFN-${\gamma}$. Based on H&E staining, CPR-E extract inhibited the infiltration of inflammatory cells into lung tissues with histological changes. Conclusions : These results indicate that CPR-E extract has anti-inflammatory and anti-allergic responses through regulating the cytokine balance, suggesting that the extract may be useful for the treatment of allergic inflammatory diseases such as bronchial asthma and allergic rhinitis.

Adenophorae Radix (AR) has been used as a traditional medicine for various diseases. However, the regulatory mechanisms of AR in allergic inflammation are not yet understood. The present study was conducted to investigate the effect and mechanisms of AR on the mast cell-mediated allergic response. To determine the pharmacological mechanisms of AR in allergic inflammation, we evaluated the effects of AR on the production of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β and IL-8 as well as the activation of nuclear factor-κB (NF-κB) and caspase-1 in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). Our results demonstrated that AR effectively attenuated the PMACI-induced production of TNF-α, IL-6, IL-1β and IL-8 in stimulated HMC-1. Additionally, we showed that the inhibitory effect of AR on inflammatory cytokines in PMACI-stimulated HMC-1 cells involved the suppression of the activation NF-kB/caspase-1 in PMACI-stimulated HMC-1. Collectively, these findings provide experimental evidence that AR may be a useful candidate for the treatment of allergic inflammation.

Objectives : In this study, we investigate the anti-allergic effects of Ullmus macrocarpa Hance (Ulmus) on RBL-2H3 mast cell (basophilic leukemia cell line), which are mediated by FcεRIs. Methods : We evaluated the effect of the ethanol extract of Ulmus on the allergic inflammatory response in IgE-antigen-mediated RBL-2H3 cells. Cell toxicity was determined by MTT assay and the markers of degranulation such as beta-hexosaminidase, histamine, PGD2, TNF-α, IL-4, IL-6 production of inflammatory mediators and FcεRI-mediated protein expression by western blot. Results : Ulmus inhibited degranulation and production of allergic mediators (e.g., TNF-α, IL-4, and IL-6) in them. Ulmus reduced histamine levels, expression of FcεRI signaling-related genes such as Lyn, Syk, and Fyn, and extracellular signal-regulated kinase phosphorylation in mast cells. Also, Ulmus reduced PGD2 release and cyclooxygenase-2 expression, and cytosolic phospholipase A2 phosphorylation in FcεRI-mediated RBL-2H3 mast cells. Conclusions : These results indicate that Ulmus exhibits anti-allergic activity through inhibition of degranulation and inflammatory mediators and cytokine release. These findings suggest that Ulmus may have potential as a prophylactic and therapeutic agent for the treatment of various allergic diseases.

Allergic diseases have increased rapidly over the past decades, affecting an estimated 20~30% of the population in developed countries. In this study, we investigated whether or not a typical costal sand dune plant Carex pumila (CPE) suppresses the activation of mast cells and IgE-mediated allergic response in vitro and in vivo. As the results, the extract of Carex pumila inhibited antigen-stimulated degranulation in RBL-2H3 cells and Bone marrow-derived mast cells (BMMCs), and IgE-mediated passive cutaneous anaphylaxis (PCA) in mice. CPE also suppressed the production of pro-inflammatory cytokines, TNF-${\alpha}$ and IL-4, in antigen-stimulated mast cells. As its mechanism of action, CPE inhibited the activation of Syk in $Fc{\varepsilon}RI$-mediated signalling pathway, and that of LAT, a downstream adaptor molecule of Syk, in a dose-dependent manner. CPE also suppressed the activation of mitogen-activated protein (MAP) kinases, p38, ERK1/2, JNK, and Akt. Altogether, CPE inhibited mast cell activation and IgE-mediated allergic response by antigen through suppressing the activation of Syk. These results suggest that CPE may be useful for the treatment of allergic diseases.

Objectives : Ulmus davidiana (UD) has been widely used in Korean herbal medicines used for treatment of acute and chronic inflammatory diseases, such as rhinitis, asthma, and abscess. In this study, To investigated the protective effect of UD on type 1 allergic response, we determined whether UD inhibits early and late allergic response. Methods : The effect of UD was analyzed by ELISA and RT-PCR in RBL-2H3 cells. Levels of ${\beta}$ -hexosaminidase, interleukin (IL)-4 and TNF-${\alpha}$ were measured using enzyme-linked immunosorbent assays (ELISAs). mRNA levels of COX-2 and T-helper type 2(Th2) cytokines were analyzed with RT-PCR. Results : We found that UD suppressed ${\beta}$-hexosaminidase release in RBL-2H3 not only by the PMA plus A23187 stimulation, but also by the IgE-DNP-HSA stimulation at the antigen-antibody binding stage and antibody-receptor binding stage. UD also significantly inhibited COX2 level, along with reduced Th2 cytokine levels, such as IL-3, IL-4, IL-5, IL-13, GM-CSF, and TNF-${\alpha}$ in RBL-2H3. Conclusions : Our results indicate that UD protects against type 1 allergic response and exerts an anti-inflammatory effect through the inhibition of degranulation and expression of COX2 and Th2 cytokines.

Gunjung-tang(GJT) has been reported at Shanghanlun(傷寒論), which has been used for the treatment of general weakness, digestive organ disease and the treatment of allergic disorders in clinical medicine. However, its effect in experimental models remains unknown. In a rat and mouse model, the role of GJT was examined in mast cell-dependent allergic reactions and secretion of inflammatory cytokines. GJT inhibited anti-dinitrophenyl IgE antibody-induced passive cutaneous anaphylaxis reaction by Intraperitoneal pretreatment. GJT inhibited both IL-1β and TNF-α secretion on egg albumin induced allergic tissues and compound 48/80 induced thymus. Furthermore, GJT enhanced Band T lymphocytes proliferation. Our findings provide evidence that GJT inhibits the IgE-dependent allergic reactions and inflammatory cytokines secretion, and enhanced immune response.
