Objectives : On an experimental basis, the effects of atopic dermatitis induced materials on the expression of cytokine genes in human monocytes (THP-1, U937) and mast cells were studied. This study was carried out to be considered a fundamental knowledge in the research on the good of oriental medicine. Methods : After culturing THP-1, U937, and HMC-1, with the three different concentrations of LPS ($1\;{\mu}g/ml$), DPE ($10\;{\mu}g/ml$), and DNCB ($1\;{\mu}g/ml$), atopic dermatitis induced materials were treated in the culture medium. To investigate cytokine genes expression patterns, with lysis buffer and separation reagent, total RNA was extracted from THP-1, U937, and HMC-1 at intervals of 0, 12, 24, and 48 hours. Both cytokine mRNA expression patterns by atopic dermatitis induced materials and change of cytokine genes expression patterns in relation to atopy by selenium were analyzed with RT-PCR. Also IL-4 and INF-$\gamma$, which were secreted in the HMC-1, were analyzed using ELISA method. Results : 1. After treating THP-1 and U937 with LPS, DPE, and DNCB, there was no significant change in cytokine genes themselves, but various cytokines (IL-4, IL-6, IL-8, IL-13, IFN-$\gamma$, IFN-a, MCP-1, B2-MG) were expressed. 2. In the case of HMC-1, the expressions of IL-6 and IL-8 were significantly increased in the analysis of mRNA expression by dust mite allergens in DPE. 3. As a result of ELISA method, it is certain that IL-4 and IFN-$\gamma$ protein were secreted in the HMC-1 by DPE. 4. Selenium, an essential trace element, decreased the IL-10 and IL-13 expression in the HMC-1 by DPE. Conclusion : The results suggest that it is necessary to choose proper atopic dermatitis induced materials and suitable cultured cells in establishment of in vitro model of atopic dermatitis.

The discovery of drugs on the treatment of mast cell-mediated allergic disease is a very important subject in human heath. The Socheongyoug-tang(SCYT) has been used for centruries 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 SCYT on RBL-2H3 mast cell-mediated allergic reaction and studied its possible mechanism of action. SCYT inhibited compound 48/80-induced systemic anaphylaxis and serum histamine release in mice. SCYT decreased the passive cutaneous anaphylaxis reaction activated by Anti-lgE antibody-HSA. SCYT dose-dependently reduced histamine release from mice peritoneal mast cells activated by Anti-lgE antibody-HSA. SCYT increased cAMP and decreased compound 48/80-induced intracellular $Ca^{2+}$ levels. Our findings provide evidence that SCYT inhibits mast-derived allergic reactions, and also demonstrate the involvement of cAMP and intracellular $Ca^{2+}$ in these effects.

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.

Natural products have received revived interest via traditional remedies or alternative medicine used for the treatment of various diseases. Zanthoxylum piperitum (ZP) has been utilized in traditional medicine for various medicinal purposes. The present study was conducted to evaluate whether ZP modulates allergic inflammation both in vivo and in vitro. We examined the pharmacological effects of ZP on 2, 4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD) symptoms in mice. Additionally, in order to clarify the anti-inflammatory mechanisms of ZP, we elucidate the effect of ZP on the expression levels of inflammatory cytokines and nuclear factor-κB (NF-κB) in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). The results demonstrated that ZP attenuated AD clinical symptoms such as erythema, edema and dryness as well as histamine and IgE serum levels in DNCB-induced AD model mice. Additionally, ZP suppressed the expression of inflammatory cytokines and activation of NF-κB in AD-like skin lesions and stimulated HMC-1. These results provide experimental evidence that ZP may be useful candidate for treating allergic inflammation including AD.

In this study, we investigated the effect of Phellinus baumii (PB) on immediate-type allergic reaction and inflammatory cytokine secretion. PB inhibited compound 48/80-induced systemic reactions in mice. PB inhibited compound 48/80-induced plasma histamine release. In addition, PB also inhibited the immunoglobulin (Ig) E-mediated local allergic reaction. Furthermore, PB decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated tumor necrosis $factor-\alpha$ and interleukin-6 secretion in human mast cells. These results indicate that PB may be beneficial in the treatment of immediate-type allergic reactions.

Cyanidin 3 - rutinoside chloride (CRC) is major anthocyanin, found in Schisandra chinensis, is known to have antioxidant, anticancer, anti-inflammatory, tonic, and anti-aging effects in Korea, China and Japan. In the present study, the human mast cell line (HMC-1) was used to investigate the effects on the production of pro-inflammatory mediators. In this study, CRC showed no cytotoxicity in HMC-1. CRC significantly inhibited the secretion of inflammatory cytokines such as tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-6 in PMA plus A23187 cacium ionophore (PMACI)-stimulated HMC-1 cells. In addition, CRC suppressed the serum levels of IgE. Furthermore, CRC decreased the PMACI- stimulated phosphorylation of mitogen activated protein kinases (MAPKs) such as p-ERK, p- JNK and p-P38. These results indicate that the pharmacological actions of CRC suggest their potential activity for treatment of allergic inflammation through the down-regulation of mast cell activation.

Ji-Jang-Soo (JJS) is known to have a detoxification effect. However, it is still unclear how JJS has these effects in experimental models. In this study, we investigated the effect of JJS on the viability of cells and production of cytokines in human T-cell line, MOLT-4 cells, and human mast cell line, HMC-1 cells. The MOLT-4 cells were cultured for 24 h in the presence or absence of JJS. As the result, JJS (1/100 dilution) significantly increased the cell viability about 78% (P < 0.05) and also increased the interleukin (IL)-2, and interferon $(IFN)-{\gamma}$ production compared with media control at 24 h. But had no effect on IL-4 production. Hypoxia mimic compound, desferroxamine (DFX) decreased the immune cell viability. Cell viability decreased by DFX was increased by JJS. In conclusion, these data indicate that JJS may have an immune-enhancing effect.

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.

This study investigated the role of Panax ginseng (PG) on the phorbol myristate acetate (PMA) + calcium ionophore A23187-induced hypoxia-inducible factor-$1{\alpha}$ (HIF-$1{\alpha}$) activation, phosphorylation of the extracellular signal-regulated kinase (ERK), and inflammatory cytokine production from the human mast cell line, HMC-1. HIF-$1{\alpha}$ and phosphorylation of ERK were observed by Western blotting. The inflammatory cytokine production was determined by enzyme-linked immunosorbent assay. PG inhibited the PMA+A23187-induced HIF-$1{\alpha}$ expression and the subsequent production of vascular endothelial growth factor. In addition, PG suppressed PMA + A23187-induced phosphorylation of ERK. We also show that the increased cytokines interleukin (IL)-$1{\beta}$, IL-6, and tumour necrosis factor-${\alpha}$ level was significantly inhibited by treatment of PG. In the present study, we report for the first time that PG is an inhibitor of HIF-$1{\alpha}$ and cytokines on the mast cell-mediated inflammatory responses.
