Objectives: In this study, we investigated the inhibitory effects of Ampelopsis Radix methanol(AR-M) extract on allergic inflammation in activated human mast cells and its potential therapeutic or toxic effects. Methods: Ampelopsis Radix(AR) was extracted with 80% methanol. HMC-1 cells, a human mast cell line, were treated with different concentrations of AR-M extract, and then stimulated with PMA plus A23187. The cell toxicity of AR-M extract was determined by MTT assay. The concentrations of $PGE_2$ and cytokines were measured by ELISA. The gene expression of COX-2 and its protein levels were determined by RT-PCR and Western blot. The phosphorylation of ERK MAPK and the NF-${\kappa}B$ activation were determined by Western blot. Results: AR-M extract was significantly inhibited the production of PGE2 and inflammatory cytokines(TNF-${\alpha}$, IL-6 and IL-8) in PMA/A23187-stimulated HMC-1 cells. AR-M extract also attenuated the mRNA expression of COX-2 and its protein induction. Furthermore, AR-M extract attenuated PMA/A23187-induced phophorylation of ERK1/2 MAPK and the NF-${\kappa}B$ p65 subunit translocation into nuclear of HMC-1 cells. AR-M extract significantly decreased PMN A23187-induced release of histamine in a dose-dependent manner. Conclusions: These results indicate that Ampelopsis Radix shows the property of anti-allergic inflammation In vitro through suppressing the production of inflammatory mediators released from mast cells, suggesting have a potential for the treatment of allergic diseases.

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.

Silibinin is the major active molecule of silymarin, the mixture of flavonolignans extracted from Cirsium japonicum (CJ). It has been used for treatment of hepatitis and inflammation related diseases. The aim of this study was to prove whether Silibinin has effectiveness for allergic inflammation. Silibinin processes the inflammatory reaction in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (PMA plus A23187) stimulated human mast cell line (HMC-1). Its effect was examined by ELISA, RT-PCR, Western blot, and Luciferase assay. The results were Silibinin inhibited the expression of histamine, TNF-$\alpha$ (tumor necrosis factor-$\alpha$), IL-6 (interleukin-6), and IL-8 (interleukin-8). Silibinin suppressed NF-${\kappa}B$ (nuclear factor kappa B) activation in stimulated HMC-1 (human mast cell-1). This effect was mediated through inhibition of phosphorylation and degradation of $IkB{\alpha}$, an inhibitor of NF-kB. Silibinin significantly inhibited induction of NF-kB promoter mediated Luciferase assay. These results suggest that Silibinin has a potential molecule for therapy of mast cell-derived allergic inflammatory diseases.

The immediate-type allergic reaction (anaphylaxis) is involved in many allergic diseases such as asthma, allergic rhinitis, and sinusitis. The discovery of drugs for the treatment of immediate-type allergic diseases is a very important subject in human health. In this study, we investigated the effect of Rubus coreanus Miq.(Rosaceae) unripe fruits (RCF) on mast cell-mediated allergic reaction and inflammatory cytokine secretion. RCF inhibited compound 48/80-induced systemic reactions in mice. RCF attenuated immunoglobulin (Ig) E-mediated local allergic reactions. In addition, RCF dependently reduced histamine release from rat peritoneal mast cells local allergic reactions. In addition, RCF dependently reduced histamine release from rat peritoneal mast cells activated by compound 48/80 or IgE. Furthermore, RCF decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-6 secretion in human mast cells. Our findings provide evidence that RCF inhibits mast cell-derived immediate-type allergic reactions.

Background : Although the pathophysiology of asthma has been reported, its mechanism has not been fully elucidated. The mast cell is an effector cells in allergic inflammation and secretes a number of chemokines. Chemokines are important for the recruitment of leukocytes to sites of infection, which is essential in host defense. Chemokines also contribute to the pathogenesis of several disorders such as asthma, chronic bronchitis, atopic dermatitis, allergic rhinitis, and rheumatoid arthritis. Objective : In this study, the aim was to identify the effect of Baekryunchihyo-tang(白蓮治哮湯) on expression of chemokines. This was examined by RT-PCR using the human mast cell line (HMC-l) Materials and Methods : HMC-l cells were used, which is known to secrete and express chemokines. In order to investigate the protective effect of Baekryunchihyo-tang(白蓮治哮湯), HMC-l cells were incubated with pretreatment of Baekryunchihyo-tang(白蓮治哮湯) for 24 hrs. RT-PCR analyses of chemokine genes of cells pretreated with Baekryunchihyo-tang(白蓮治哮湯) showed that expressions of IL-8, $MIP-l{\beta}$, and RANTES genes in these cells were lower and $MIP-l{\alpha}$ showed a similar pattern compared to the calcium ionophore-treated group. In addition, cell cytotoxicity concentration measurements were performed by MTT assay method. Results : After stimulation with 1 uM calcium ionophore A23178 for 2 hrs, IL-8, major one of CXC chemokines, was highly expressed, and expression of $MIP-l{\beta}$ and RANTES (CC chemokines) increased, while expression of $MIP-l{\alpha}$ did not change. The cell cytotoxicity of Baekryunchihyo-tang(白蓮治哮湯) with treatments at various concentrations and times was not observed, respectively. Conclusion : This study suggests that Baekryunchihyo-tang(白蓮治哮湯) has dose-dependent effects on mRNA expression of IL-8(CXC chemokines), $MIP-l{\beta}$ and RANTES(CC chemokines) in human mast cellline(HMC-l). So these herbal medicines may inhibit the inflammatory process of asthma. Advanced studies are required to investigate the mechanism of inhibition by herbal medicine in the asthma model. This study provides basic data on the possibility of the clinical treatment of Baekryunchihyo-tang(白蓮治哮湯) for allergic disorders.

Bambusae Caulis in Liquamen(BCL) has been used to relieve the cough and asthma, and remove the phlegm in traditional Oriental medicine. In recent years, it was studied for its antiinflammatory, antiallergenic, immune-modulating, and anticarcinogenic capabilities. This experiment was performed to evaluate the microarray profiles of CD genes in human mast cells before and after BCL treatment. The results are as follows: The expression of 51 of the genes studied was up-regulated in the Bel-treated group; they include the genes coding L apoferritin, beta-2-microglobulin, ferritin light polypeptide, CD63, monocyte chemotactic and activating fact, heme oxygenase 1, CD140a, integrin alpha M, colony stimulating factor 2 receptor, eukaryotic translation elongation factor, CD37, interleukin 18, NADH dehydrogenase 1 beta, CD48, 5-lipoxygenase activating protein, interleukin 4, ribosomal protein L5, GABA(A) receptor-associated protein, beta-tubulin, integrin beta 1, CD162, CD32, lymphotoxin beta, alpha-tublin, integrin alpha L, CD2, CD151, CD331, 90 kDa heat shock protein, CD59, CD3Z, microsomal glutathione S-transferase 2, CD33, CD162R, cyclophilinA, CD84, interleukin 9 receptor, interleukin 11, CD117, CD39-Like 2, and so forth. The expression of 7 of the genes studied was down-regulated in the BCL-treated group; they include the genes coding con, CD238, SCF, CD160, CD231, CD24, and CD130. Consequently, the treatment of BCL on the human mast cells increased the expression of 51 genes and decreased the expression of 7 genes. These data would provide a fundamental basis to the traditional applications of Bambusae Caulis in Liquamen.

We studied the effect of Rubus croceacanthus Leveille (RCL) on mast cell-mediated anaphylactic reactions. RCL inhibited compound 48/80-induced systemic anaphylactic shock. When RCL was given at concentrations ranging from 0.01 to 1 mg/$m\ell$, the histamine release from rat peritoneal mast cells induced by compound 48/80 was reduced in a dose-dependent manner. RCL also inhibited passive cutaneous anaphylaxis activated by anti-dinitrophenyl IgE. In addition, RCL inhibited phorbol 12-myristate 13-acetate and A23187-induced tumor necrosis factor-${\alpha}$ secretion from human mast cell line HMC-1 cells. These results indicate that RCL may possess a strong anti-anaphylactic activity.

Objective : Houttuyniae Herba is widely used in oriental medicine as a remedy for inflammation. However, as yet there is no clear explanation of how Houttuyniae Herba affects the production of inflammatory cytokine. This study was to determine the effects of Essence extracted from Houttuynia cordata Thunb(HCT) on the mast cell-mediated inflammatory responses. Method : We measured the amount of inflammatory cytokine production induced by the phorbol myristate acetate (PMA) plus calcium ionophore(A23187) in the human mast cell line (HMC-1) incubated with various concentrations of HCT. The TNF-$\alpha$, IL-6 and IL-8 secreted protein levels were measured by the ELISA assay. The TNF-$\alpha$, IL-6 and IL-8 mRNA levels were measured by the RT-PCR analysis. Nuclear and cytoplasmic proteins were exmined by Western blot analysis. The NF-$\kappa$B promoter activity was examined by a luciferase assay. Result : HCT inhibited the PMA + A23187-induced TNF-$\alpha$, IL-6 expression and reduced mRNA of TNF-$\alpha$, IL-6 and IL-8. we observed that HCT suppressed the induction of NF-B activity. In addition, HCT suppressed PMA plus A23187-induced NF-$\kappa$B promoting activity. Conclusion : In this study, we have found that HCT is an inhibitor of NF-$\kappa$B and cytokines on the mast cell-mediated inflammatory responses.
