  • 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.

  • An extensive phytochemical investigation of the polar fractions of a methanolic extract of Egyptian medicinal food, black cumin (seeds of Nigella sativa L.) led to the isolation of two new triterpene saponins, named sativosides A and B (1-2), along with four known saponins (3-6). Sativoside A (1) is the first example of saponins containing 18-ene triterpene aglycon not only in this Nigella genus but also in the family Ranunculaceae. The structure of the new saponins was elucidated mainly by a combination of 1D and 2D NMR data, together with HRFABMS and acid hydrolysis. Three compounds (1-3) showed the significant inhibition effect of phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187-induced production of IL-6 in a human mast cell (HMC-1) line.

  • Equisetum hyemale Linne. (EH) (Equisetaceae) has been used for the treatment of eye and skin disease, chronic eczema, pneumoconiosis and asthma in Korea and China. Human leukemic mast cells are widely distributed in the connective tissues of mammals and other vertebrates. Phorbol 12-myristrate 13-acetate (PMA) and calcium ionophore A23187 stimulated Human leukaemic mast cell line-1 (HMC-1) can produce a variety of inflammatory mediators and several pro-inflammatory and chemotactic cytokines such as TNF-$\alpha$, IL-6 and IL-8. Since TNF-$\alpha$, IL-6 and IL-8 are major factors during the inflammatory process, we studied the effects of EH on TNF-$\alpha$, IL-6 and IL-8 release in HMC-1 stimulated with PMA and A23187. The result of this study indicate that EH inhibits TNF-$\alpha$, IL-6 and IL-8 in activated HMC-1 cells via $I{\kappa}B$/Nuclear factor-${\kappa}B$ pathway. Therefore, EH might contribute significantly to the prevention or treatment of mast-cell mediated inflammatory diseases and EH has potential use in the therapy of chronic allergic inflammation.

  • Objective : Lacca Sinic: Exsiccate (LSE) extracted from Rhus vemicitlus Stokes (RVS) has been used traditionally as a remedy for inflammation in Korea, China, and Japan. However, as yet there is no clear explanation of how LSE affects the production of inflammatory cytokines. This study was to determine the effects of LSE 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(A231S7) in the human mast cell line (HMC-l) incubated with various concentrations of Laces Sinica Exsiccate (LSE). 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 examined by Western blot analysis. The NF-${\kappa}B$ promoter activity was examined by a luciferase assay. Result : LSE inhibited the PMA + A231S7-induced $TNF-\alpha$, IL-6, and IL-8 expression and suppressed NF-${\kappa}B$ activation in the stimulated-HMC-1. In addition, LSE inhibited induction of NF-${\kappa}B$ promoter-mediated luciferase activity. Conclusion : In this study, we have found that LSE is an inhibitor of NF-${\kappa}B$ and cytokines on the mast cell-mediated inflammatory responses.

  • In this report, we investigated the effect of aqueous extract of vinegar treated small black soybean (Glycine max Merr.) (Leguminosae) (VSBS) on mast cell-mediated allergic reaction and pro-inflammatory cytokine secretion. VSBS inhibited compound 48/80-induced systemic reactions. VSBS attenuated immunoglobulin (Ig) E-mediated passive cutaneous anaphylaxis. In addition, VSBS decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated secretion of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and interleukin (IL)-8 in human mast cells. Our findings provide evidence that VSBS inhibits mast cell-derived allergic reactions.

  • Activated mast cells play pivotal roles in allergic and non-allergic inflammatory responses through the release of inflammatory mediators such as histamin, cysteinyl leukotriens, pro-inflammatory cytokines as well as chemokine. We tested whether YHJST, which is clinically prescribed for the treatment of various inflammatory disease including allergic disease, modulate inflammatory reactions in activated mast cells. YHJST decreased the release of histamine and b-hexosamidase in pholbol-12-myristate 13-acetate and/or calcium ionophore A23187 stimulated HMC-1 and RBL-2H3 cells, respectively. Further, the gene expressions of tumor necrosis factor-a, IL-6 and IL-8 were significantly reduced by YHJST. YHJST suppressed powerful induction of NF-kB promoter-mediated luciferase activity. Taken together, these data suggested that YHJST showed it's anti-inflammatory effects through the down-regulation of mast cell activation.

  • 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.

  • Marine sources as potential treatment options for various diseases have been a subject of growing interest. However, information on the anti-inflammatory mechanism employed by Undaria pinnatifida (UP) remains limited. The present study was conducted to investigate the mechanisms of UP on the mast cell-mediated inflammatory response. To determine the pharmacological mechanism of UP in inflammatory reaction, we evaluated the effects of UP on interleukin (IL)-6, IL-8 and tumor necrosis factor (TNF)-α production and nuclear factor-κB (NF-κB) and caspase-1 activation in calcium ionophore A23187 plus phorbol 12-myristate 13-acetate-stimulated human mast cells-1 (HMC-1). The results showed that UP suppressed IL-6, IL-8 and TNF-α production in a dose-dependent manner. Moreover, UP significantly attenuated NF-kB/caspase-1 activation in stimulated HMC-1. Collectively, these findings provide experimental evidence that UP may be a useful candidate for the inflammation-related diseases treatment.

  • Isoegomaketone(IK), isolated from the radiation-induced mutant cultivar of Perilla frutescens var. crispa, is a major phytochemical compound that has attracted attention in pharmacological research. In this study, we demonstrated that IK exerts anti-inflammatory and protective effects on human mast cells and in an atopic dermatitis mouse model. IK inhibited tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), and IL-8 expression in human mast cells (HMC-1) stimulated with phorbol myristate acetate(PMA) and calcium ionophore A23187 (PMACI). IK significantly reduced the PMACI-induced phosphorylation of ERK and JNK, but not p38. IK also inhibited the PMACI-induced phosphorylation of STAT1 and STAT3. Oral administration of IK in atopic dermatitis mouse model ameliorated skin inflammation severity, as measured by skin thickness and pro-inflammatory cytokine levels such as TNF-α, IL-8, IL-4, and IL-13. These results might suggest that IK is a potent therapeutic agent against skin inflammation and atopic dermatitis.

  • This experiment was carried out to clarify the effect of lead poisoning on the lead and essential trace elements homeostasis of tissues in rats. Fifty female Wistar rats, 7 weeks old, were divided into four experimental groups(B, C, D, and E) and a control(A). The four experimental groups received diets contaminated artificially with 10 (B group), 100 (C group), 1,000 (D group) and 5,000 (E group) ${\mu}g/g$ of lead as lead acetate, respectively. The control group received normal diet. Rats were necropsied on the 4th or 8th week of experimental periods and heart, liver, spleen, kidney, muscle, lung and hair were taken. The tissues were analysed for lead, copper, zinc, iron and calcium content by atomic absorption spectrophotometry. From these experiments following results ware obtained ; In C group, lead content of the heart, liver, kidney and hair were significantly increased both on the 4th and 8th week of experiment. In D and E group, lead content of all tissues including heart, liver, spleen, kidney, muscle, hair and lung were significantly increased in accordance with the lead contamination both on the 4th and 8th week of experiment. In C group, copper content of tissues were significantly increased in the heart, liver, kidney and lung on the 4th week and all tissues on the 8th week of experimental periods. In D and E group, copper content of the liver were significantly increased both on the 4th and 8th week of experiment. But the copper content of tissues were gradually decreased compared with C group in accordance with the lead contamination. Especially the content in spleen, heart or kidney were significantly decreased compared with the control group. The zinc content of kidney, heart, or spleen were decreased in D and E groups whereas the iron and calcium content showed no significant change.
