The mast cell-mediated immediate-type allergic reaction is involved in many allergic diseases such as asthma, allergic rhinitis, and sinusitis. The discovery of drugs for the treatment of mast cell-mediated immediate-type allergic diseases is a very important subject in human health. In this study, we investigated the effect of small black soybean (Glycine max Merr.) (Leguminosae) on mast cell-mediated allergic reaction and pro-inflammatory cytokine secretion. Small black soybean (SBS) inhibited compound 48/80-induced systemic reaction. SBS attenuated immunoglobulin (Ig) E-mediated local allergic reaction. In addition, SBS decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-8 secretion in human mast cells. These results indicate that SBS may be beneficial in the treatment of mast cell-mediated immediate-type allergic reactions.

We investigated the effect of aqueous extract of Cichorium intybus (CIAE) on mast cell-mediated immediate type allergic reactions. CIAE dose-dependently inhibited systemic anaphylactic reaction induced by compound 48/80 in mice. Especially, CIAE inhibited compound 48/80-induced anaphylactic reaction 100% with the dose of 1000 mg/kg. CIAE 1000 mg/kg also significantly inhibited local anaphylactic reaction activated by anti-dinitrophenyl (DNP) IgE. When mice were pretreated with CIAE at a concentration ranging from 0.1 to 1000 mg/kg, the plasma histamine levels were reduced in a dose-dependent manner. CIAE (1 to 1000 g/ml) dose-dependently inhibited histamine release from the rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-DNP IgE. These results indicate that CIAE inhibits mast cell-mediated immediate-type allergic reactions.

Immediate-type hypersensitivity is involved in many allergic diseases such as asthma, allergic rhinitis and anaphylaxis. The discovery of drugs for the treatment of allergic disease is an important subject in human health. Stimulation of mast cells releases inflammatory mediators, such as histamine and pro-inflammatory cytokines with immune regulatory properties. We investigated the effect of the aqueous extract of Schizonepeta tenuifolia (AEST) (Labiatae) on the immediate-type allergic reaction. AEST inhibited compound 48/80-induced systemic allergic reaction. AEST attenuated immunoglobulin E (IgE)-mediated skin allergic reaction and histamine release from human mast cell line (HMC-1) cells. In addition, AEST decreased the gene expression and secretion of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (A23187)-stimulated HMC-1 cells. Our results indicate that AEST inhibits the mast cell-derived allergic reactions and involvement of histamine and pro-inflammatory cytokines in these effects.

The discovery of drugs for the treatment of mast cell-mediated allergic disease is a very important subject in human health. The Amomum xanthiodes (Zingiberaceae) has been used for centuries as a traditional medicine in Korea and is known to have an anti-inflammatory effect. However, its specific mechanism of action is still unknown. In this report, we investigated the effect of hot water extract from Amomum xanthiodes (EAX) on the mast cell-mediated allergic reaction and studied its possible mechanisms of action. EAX inhibited compound 48/80-induced systemic anaphylaxis and serum his­tamine release in mice. EAX decreased the passive cutaneous anaphylaxis reaction activated by anti-dinitrophenyl (DNP) IgE antibody. EAX dose-dependently reduced histamine release from rat peritoneal mast cells activated by compound 48/80 or anti-DNP IgE. EAX increased cAMP and decreased compound 48/80-induced intracellular $Ca^{2+}$ levels. Our findings provide evidence that EAX inhibits mast cell-derived allergic reactions, and also demonstrate the involvement of cAMP and intracellular $Ca^{2+}$ in these effects.

We compared the effect between CAS and WAS(root, stem) on mast cell-mediated allergic reaction. CAS, WAS-root and WAS-stem, significantly inhibited compound 48/80-induced systemic allergic reaction(1g/kg) and histamine release from RPMC(1mg/ml). CAS, WAS-root and WAS-stem also inhibited passive cutaneous anaphylactic reaction. In addition, IgE-induced $TNF-{\alpha}$ secretion from RBL-2H3 was inhibited by pretreatment of CAS, WAS-root or WAS-stem$(0.01{\mu}g/ml)$. Taken together, inhibitory effect on mast cell-mediated allergic reactions of WAS-root is greater than those of WAS-stem but less than those of CAS.

Mast cells are crucial as effector cells in the immediate-type allergic reaction. Lentinus edodes has been the popular edible mushroom in oriental countries and reported to have immunomodulatory, anti-tumor, anti-atherogenic, anti-viral, and anti-allergic activities. However, the roles of L. edodes in mast cell-mediated anaphylactic reaction have not been fully elucidated. In this research, we have demonstrated the effects of the methanol extract of L. edodes (MELE) on mast cell-mediated anaphylaxis-like and anaphylactic reactions. MELE suppressed systemic anaphylaxis-like reaction, plasma histamine levels, and ear swelling response in mice treated with compound 48/80. MELE also suppressed passive systemic and cutaneous anaphylaxis mediated by anti-dinitrophenyl IgE. In accordance with these findings, MELE dose-dependently decreased histamine release from RPMC evoked by compound 48/80 or the antigen-antibody reaction. To clarify the mechanism of degranulation system, intracellular cAMP levels as well as calcium influx in RPMC was evaluated. In compound 48/80-treated RPMC, MELE blocked calcium uptake into the cells. In addition, MELE elevated the intracellular cAMP content and significantly attenuated compound 48/80-induced cAMP reduction in RPMC. Taken together, we propose the clinical use of MELE in mast cell-mediated immediate-type allergic diseases.

In the present study, we investigated the effect of the water extract of Perilla frutescens var. acuta (Labiatae; WEPF) on the mast cell-mediated allergic reactions. WEPF was anally administered to mice for high and fast absorption. WEPF inhibited compound 48/80-induced systemic allergic reaction. WEPF attenuated immunoglobulin E (IgE)-mediated local allergic reaction. In addition, WEPF decreased the gene expression of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated HMC-1 cells. These results indicate that WEPF inhibits mast cell-mediated allergic reactions in vivo and in vitro.

Mast cell-mediated allergic disease is involved in many diseases such as anaphylaxis, asthma and atopic dermatitis. The discovery of drugs for the treatment of allergic disease is an important subject in human health. In the present study, the effect of water extract of Gleditsiae Spina (WGS) (Leguminosae), on compound 48/80-induced systemic allergic reaction, anti-DNP IgE antibody-induced local allergic reaction, and histamine release from human mast cell line (HMC-1) cells were studied. In addition, the effect of WGS on phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (A23187)-induced gene expression and secretion of pro-inflammatory cytokines were investigated using HMC-1 cells. WGS was anally administered to mice for high and fast absorption. WGS inhibited compound 48/80-induced systemic allergic reaction. WGS dose-dependently decreased the IgE-mediated passive cutaneous anaphylaxis. WGS reduced histamine release from HMC-1 cells. In addition, WGS decreased the gene expression and secretion of pro-inflammatory cytokines in PMA plus A23187-stimulated HMC-1 cells. These findings provide evidence that WGS could be a candidate as an antiallergic agent.

Background: Ginsenoside Rg3 (G-Rg3) is the major bioactive ingredient of Panax ginseng and has many pharmacological effects, including antiadipogenic, antiviral, and anticancer effects. However, the effect of G-Rg3 on mast cell-mediated allergic inflammation has not been investigated. Method: The antiallergic effects of G-Rg3 on allergic inflammation were evaluated using the human and rat mast cell lines HMC-1 and RBL-2H3. Antiallergic effects of G-Rg3 were detected by measuring cyclic adenosine monophosphate (cAMP), detecting calcium influx, and using real-time reverse transcription polymerase chain reaction, enzyme-linked immunosorbent assay, Western blotting, and in vivo experiments. Results: G-Rg3 decreased histamine release from activated mast cells by enhancing cAMP levels and calcium influx. Proinflammatory cytokine production was suppressed by G-Rg3 treatment via regulation of the mitogen-activated protein kinases/nuclear factor-kappa B and receptor-interacting protein kinase 2 (RIP2)/caspase-1 signaling pathway in mast cells. Moreover, G-Rg3 protected mice against the IgE-mediated passive cutaneous anaphylaxis reaction and compound 48/80-induced anaphylactic shock. Conclusion: G-Rg3 may serve as an alternative therapeutic agent for improving allergic inflammatory disorders.

The effect of aqueous extract of Isodon japonicus Hara (Labiatae) (IJAE) on mast cell-mediated immediate-type allergic reactions was investigated. IJAE inhibited compound 48/80-induced systemic anaphylaxis and immunoglobulin E (IgE)-mediated local anaphylaxis. When IJAE was pretreated at the same concentration with systemic anaphylaxis, serum histamine levels were reduced in a dose-dependent manner. IJAE dose-dependently inhibited histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. The level of cAMP in human mast cell line (HMC-1) cells, when IJAE was added, significantly was increased, compared with that of normal control. These results indicate that IJAE will beneficial in the treatment of immediate-type allergic reaction.
