  • Artemisiae Asiaticae Herba (AAH) has been used to remedy of symptoms such as bleeding, dysmenorrhea, eczema and itchy skin in Oriental Medicine. In this study, we investigated the protective effect of AAH on allergic response. The effect of AAH was analyzed by ELISA and RT-PCR in RBL-2H3 cells. We investigated cell viability, ${\beta}$-hexosaminidase and histamine as markers of degranulation, production of IL-4 and TNF-${\alpha}$, and gene expression of HDC2, cytokines and $Fc{\varepsilon}RI$ ${\alpha}{\beta}{\gamma}$ subunit. We found that AAH suppressed ${\beta}$-hexosaminidase and histamine release, the production of IL-4 and TNF-${\alpha}$ in RBL-2H3 by the anti-DNP IgE plus DNP-HSA stimulation. AAH also significantly decreased cytokine mRNA expressions, such as IL-$1{\beta}$, IL-2, IL-3, IL-4, IL-5, IL-6, IL-12, IL-13, TNF-${\alpha}$, and GM-CSF, and increased cytokine mRNA expressions of IL-10 in RBL-2H3. In addition, AAH suppressed mRNA expression of $Fc{\varepsilon}RI$ ${\alpha}{\beta}{\gamma}$ subunit on cell surface. Our results indicate that AAH protects against allergic response and exerts an anti-inflammatory effect through the inhibition of degranulation and production of cytokines and expression of $Fc{\varepsilon}RI$ ${\alpha}{\beta}{\gamma}$ subunit.

  • Objectives : In this report, we investigated the effect of ethanol extract of Syzygium aromaticum(L.) Merr. & Perry.(SAE) on the RBL-2H3 cell-mediated allergic response and studied its possible mechanisms of action. Methods : Cytotoxicity on RBL-2H3 cell was evaluated by MTT assay. Anti-allergic activity of SAE was assessed by ${\beta}$-Hexosaminidase and Histamine secretion, ${\beta}$- Hexosaminidase and Histamine secretion were measured by ELISA assay. Evaluate the mechanisms of effect of SAE on the secretion of degranulate mediators, we examined the effect of SAE on the activation of mitogen-activated protein kinases using western blot analysis. Results : SAE had no cytotoxicity on rat basophilic leukemia cell(RBL-2H3). Moreover SAE dose-dependently inhibited RBL-2H3 cell degranulation and histamine release. SAE specifically blocked the IgE-induced p38 mitogen-activated protein kinase activation. Conclusions : Our findings provide evidence that Syzygium aromaticum ethanol extract inhibits mast cell derived allergic reaction, and also demonstrate the involvement of p38 MAPK phosphorylation.

  • BACKGROUND : Socheongryong-Tang(小靑龍湯, SCRT), a herbal medicine, has been widely used for the control of respiratory disease in Eastern countries. Recent years SCRT was known as anti-allergic agent. However, its therapeutic mechanisms, especially an inhibitory effect on inflammatory cell infiltration and airway remodeling in allergic asthma are unclear. METHODS : We investigated the effects of SCRT on levels of IL-4, and IFN-g using flow cytometric analysis and infiltration of inflammatory cells in bronchoalveolar lavage fluid(BALF) using cytospin methods in allergen-induced asthma. RESULTS : SCRT decreased levels of IL-4, a Th2-driven cytokine. But INF-g, a Th1-driven cytokine, was not changed. With SCRT treatment, infiltration of inflammatory cells showed reduced tendency. CONCLUSION : In conclusion, we demonstrated that regulation of Th1/Th2 imbalance may be one of mechanism contributed to reduction of inflammatory cell infiltration.

  • Enhancement of antigen-specific IgE is a hallmark of allergic hyperresponsiveness, therefore it is necessary to adopt or develop a highly sensitive and specific assay for determination of allergen-specific IgE levels in vivo. In this presentation, we introduce an ELISA (enzyme linked immunosorbent assay) system developed to measure the levels of chicken egg ovalbumin (OVA)-specific IgE in serum. The ELISA method uses a commercially available purified rat anti-mouse IgE as a capture Ab and biotinylated OVA as a detection reagent. Avidin-peroxidase with its substrate is used for color development resulting in optical density measurement at 405 nm. The ELISA system produces a highly sensitive dose-response relation-ship between optical density levels and the dilution titer of the OVA-IgE standard serum but no cross-reaction with unrelated IgE or IgG. It is believed that the system is an Efficient tool to delineate an adjuvant effect of environmental pollutants on development of asthmatic and atopic responses.

  • Flos magnoliae (FM), the dry flower buds of Magnolia officinalis or its related species, is a traditional herbal medicine commonly used in Asia for symptomatic relief of and treating allergic rhinitis, headache, and sinusitis. Although several studies have reported the effects of FM on store-operated calcium entry (SOCE) via the ORAI1 channel, which is essential during intracellular calcium signaling cascade generation for T cell activation and mast cell degranulation, the effects of its isolated constituents on SOCE remain unidentified. Therefore, we investigated which of the five major constituents of 30% ethanoic FM (vanillic acid, tiliroside, eudesmin, magnolin, and fargesin) inhibit SOCE and their physiological effects on immune cells. The conventional whole-cell patch clamp results showed that fargesin, magnolin, and eudesmin significantly inhibited SOCE and thus human primary CD4+ T lymphocyte proliferation, as well as allergen-induced histamine release in mast cells. Among them, fargesin demonstrated the most potent inhibitory effects not only on ORAI1 (IC50 = 12.46 ± 1.300 μM) but also on T-cell proliferation (by 87.74% ± 1.835%) and mast cell degranulation (by 20.11% ± 5.366%) at 100 μM. Our findings suggest that fargesin can be a promising candidate for the development of therapeutic drugs to treat allergic diseases.

  • Black-red ginseng (BRGP) exhibits more potent biological activities than white and red ginseng. However, the effect of BRGP on allergic inflammation has not been studied extensively. In this study, we attempted to evaluate the effects of BRGP on allergic inflammation in vitro and in vivo. The effects of BRGP on pro-inflammatory mediators in phorbol myristate acetate (PMA) and A23187-stimulated human mast cells (HMC-1) and on trimellitic anhydride (TMA)-induced atopic dermatitis-like skin lesions in BALB/c mice were evaluated. BRGP suppressed the expression of $TNF-{\alpha}$, IL-6 and IL-8 from HMC-1 stimulated with PMA and A23187. Furthermore, the oral administration of BRGP markedly significantly reduced apparent severity of atopic dermatitis-like skin lesions, ear swelling, lymph node weight gains and serum IgE levels induced by TMA in mice. BRGP treatment also ameliorated epidermal hyperplasia and infiltration of inflammatory cells including mast cells. Taken together, BRGP possesses significant anti-atopic efficacy, suggesting that it could be used as a potential therapeutic agent for allergic inflammatory diseases, including atopic dermatitis.

  • Ribes fasciculatum var. chinense MAX. (R. fasciculatum) has traditionally been used in Korea to treat inflammatory diseases. However, the exact mechanism that accounts for the anti-inflammatory effect of R. fasciculatum is not completely understood. We aimed to ascertain the pharmacological effects of R. fasciculatum on both compound 48/80- or histamine-induced scratching behaviors and 2, 4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD) in mice. Additionally, to find a possible explanation for the anti-inflammatory effects of R. fasciculatum, we evaluated the effects of R. fasciculatum on the production of inflammatory mediators in LPS-stimulated macrophage cells. Treatment of R. fasciculatum significantly reduced compound 48/80- or histamine-induced the pruritus in mice. R. fasciculatum attenuated the AD symptoms such as eczematous, erythema and dryness and serum IgE levels in AD model. Additionally, R. fasciculatum inhibited the production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin-6 (IL-6). The maximal rates of TNF-${\alpha}$ and IL-6 inhibition by R. fasciculatum (1 mg/ml) were approximately 32.12% and 46.24%, respectively. We also showed that R. fasciculatum inhibited the activation of nuclear factor-kappa B in LPS-stimulated macrophages. Collectively, the findings of this study provide us with novel insights into the pharmacological actions of R. fasciculatum as a potential molecule for use in the treatment of allergic inflammatory diseases.

  • This study was conducted to investigate the effect of 70% ethanol extract (DR) on the mast cell-mediated allergic contact dermatitis induced by dinitrofluorobenzene in BALB / c mice, which affects the cell activity by antigen in RBL-2H3 mast cells Respectively. The ethanol extracts of RBL-2H3 cells activated by DNP-HSA and anti-DNP IgE antibodies inhibited the secretion of ${\beta}$-hexosaminidase, histamine, and IL-4 and $TNF-{\alpha}$ Production was suppressed. In the DNFB-induced contact allergic dermatitis animal model, treatment with ethanol extract reduced ear swelling and inhibited serum histamine and IL-4 secretion, and DR treatment effectively prevented mast cell infiltration in dermatitis-induced areas. As a result, the ethanol extract may be used as a therapeutic agent for mast cell-mediated allergic diseases such as atopic dermatitis.
