Objective: Danguieumja-gagambang (DGEJGB), a traditional Korean prescription, has been used as therapeutics for allergic diseases such as atopic dermatitis (AD). In this study, we compared with regulatory Effect of Atopic Allergic Reaction by Prescriptions A and by Prescriptions B. Methods : To evaluate and compare the atopic allergic effectiveness of two prescription (A, B) of DGEJGB, the author investigated a possible effect of DGEJGB on mast cell-mediated allergic reaction, cytokine secretion and mRNA expression in vivo and in vitro. Results : Mast cells are a potent source of mediators that regulate the inflammatory response in allergic reaction. In mice orally administered A, B of DGEJGB ( 0.1, 0.1 and 1.0 g/kg) for 1 h, compound 48/80-induced ear swelling was significantly reduced. Significant reduced levels (P < 0.05). of tumor necrosis factor $(TNF)-{\alpha}$ was observed in the human mast cell line (HMC-1) with DGEJGB (A). IL-6 and IL-8 secretion were significantly inhibited by DGEJGB (A, B). In addition, $TNF-{\alpha}$ and IL-8 mRNA expression were reduced by DGEJGB (A) at the dose of 0.01 mg/ml without cell toxicity. Conclusions : These results suggest that DGEJGB (A) contributes to the treatment of atopic allergic reactions rather than DGEJGB (B), and that its action may be due to inhibition of cytokine secretion and mRNA expression HMC-1.

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.

Cnidium monnieri (L). Cussion is used as a tonic agent in traditional oriental medicine. However, the molecular mechanism of mast cell-mediated anti-inflammatory modulation has not been fully understood. The aim of the present study was to demonstrate the effects of Cnidium monnieri (L). Cussion eathyl acetate fraction on the expression of pro-inflammatory cytokines, as well as to elucidate its mechanism of action in the human mast cell line (HMC-1). Cells were stimulated with phorbol 12-myristate 13-acetate (PMA) plus A23187 in the presence or absence of Cnidium monnieri (L). Cussion eathyl acetate fraction. Cnidium monnieri (L). Cussion eathyl acetate fraction significantly inhibited the PMA plus A23187-induction of inflammatory cytokines such as tumor necrosis factor (TNF)-$\alpha$, interleukin (IL)-6 and IL-8. Moreover, EtOAc fraction attenuated cyclooxygenase (COX)-2 expression. In activated HMC-1 cells, phosphorylation of extra-signal response kinase (ERK) 1/2 decreased after treatment with EtOAc fraction. Moreover EtOAc fraction inhibited PMA plus A23187-induced nuclear factor (NF)-${\kappa}B$ activation, $I{\kappa}B$ degradation. EtOAc fraction suppressed the expression of TNF-$\alpha$, IL-6, IL-8 through a decrease in the ERK 1/2, as well as activation of NF-${\kappa}B$. These results indicated that Cnidium monnieri (L). Cussion EtOAc fraction exerted a regulatory effect on inflammatory reactions mediated by mast cells.

Anglicae dahuricae Radix (ADR), the dried roots of Angelica Dahurica Benth et Hook (Umbelliferae), is a traditional herbal medicine used to treat colds, headache, skin diseases such as acne and possess analgesic, antipyretic and drainage effects. In the present study, the author evaluated the effect of ADR on regulation of inflammatory reaction. ADR reduced the ear-swelling responses derived from compound 48/80 in dose-dependent manner significantly. ADR inhibited the PMA plus A23187-induced productions of IL (Interleukin)-8, IL-1β, granulocyte macrophage-colony stimulating factor (GM-CSF) and tumor necrosis factor (TNF)-α from human mast cells (HMC)-1. In addition, ADR blocked PMA plus A23187-induced ERK1/2 phosphorylation. Ⅰ suggest that ADR regulates inflammatory reaction through inhibition of inflammatory cytokines such as IL-8, IL-1β and GM-CSF.

Samultang has been believed for prevention and remedy various blood diseases such as menstrual irregularity, anemia, and metrorrhagia. However, the mechanism that accounts for anti-inflammatory effects of the Samultang is still not fully understood. This study was designed to evaluate whether and how the Samultang could modulate the production of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 treated-human mast cell line, HMC-1. Samultang inhibited the production of tumor necrosis factor $(TNF)-\alpha$, interleukin (IL)-6, granulocyte macrophage colony stimulating factor (GM-CSF), and vascular endothelial growth factor (VEGF) in HMC-1. Maximal inhibition rate of $TNF-\alpha$, IL-6, GM-CSF, and VEGF by 0.1 mg/ml Samultang was about $70.73{\pm}3.0%,\;51.49{\pm}4.14%,\;54.03{\pm}2.09%$, and $47.95{\pm}7.86%$, respectively. Samultang partially blocked PMA plus A23187-induced cyclooxygenase (COX)-2 expression. In addition, Samultang inhibited activation of nuclear factor (NF)-kB, and extracellular signal-regulated kinase (ERK) activation. These results suggest that anti-inflammatory effect of Samulatng may be mediated by the suppression of cytokine production and COX-2 activation via down-regulation of NF-kB and ERK activation.

Objective : Mast cells are a potent source of mediators that regulate inflammatory response in allergies and asthma. The author studied the effect of Bojungikgitanggamibang(BITB) on mast cell-mediated anaphylactic reaction. Method : When BITB was given as pre-treatment at concentrations ranging from 0.01 to 1 mg/ml, the histamine release from rat peritoneal mast cells induced by compound 48/80 was reduced in a dose-dependent manner. Result : BITB dose-dependently inhibited compound 48/80-induced systemic anaphylactic shock. BITB also inhibited passive cutaneous anaphylaxis activated by anti-dinitrophenyl IgE. In addition, BITB inhibited phorbol 12-myristate 13-acetate and A23187-induced interleukin-6 secretion from human mast cell line HMC-1 cells. Conclusion : These results indicate that BITB may be actively anti-allergic.

Lindera obtusiloba has been used for centuries as a traditional medicine in Korea and recently known to have an anti-fibrotic effect. In this report, we investigated the effect of hot water extract from L. obtusiloba (WELB) on the mast cell-mediated allergic inflammation and studied its possible mechanisms of action. WELB inhibited phorbol-12-myristate 13-acetate and calcium ionophore A23187 (PMACI)-induced histamine release in HMC-1 human mast cells. WELB reduced PMACI-induced gene expression and secretion of proinflammatory cytokines such as tumor necrosis factor-$\alpha$, interleukin (IL)-$1{\beta}$, IL-6, and IL-8. The inhibitory effect of WELB on the expression of proinflammatory cytokines was c-jun N-terminal kinase and nuclear factor-${\kappa}B$ dependent. These results indicate that WELB may be beneficial in the treatment of mast cell-mediated allergic inflammation.

The worldwide prevalence and severity of allergic diseases including atopic dermatitis and asthma has increased dramatically over the past decade, especially in developed countries. Mast cells are important effector cells in allergic reactions. The purpose of this study was undertaken to investigate the anti-allergic activities of the extract of Duchesnea chrysantha (DCE). DCE was prepared by extracting with 80% ethanol. In the present study, we investigate the effect of DCE on the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, IL-6, IL-8, and histamine in the human mast cell line (HMC-1 cells) and on the scratching behavior in hairless mice. Various concentrations of DCE were treated before the activation of HMC-1 cells with phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187. PMA plus A23187 significantly increased TNF-${\alpha}$, IL-$1{\beta}$, IL-6, and IL-8 production compared with media control. We also show that the increased cytokines such as TNF-${\alpha}$ IL-$1{\beta}$, IL-6, and IL-8 were significantly inhibited by DCE in a dose-dependent manner. Moreover, DCE inhibited the histamine release from HMC-1 cells stimulated by compound 48/80, which promotes histamine release. Futhermore, the administration of DCE reduced the scratching behavior induced by pruritogen (compound 48/80 or histamine) in hairless mice. These results suggest that DCE has a potential use as a medicinal plant for treatment against allergy-related disease.
