Gamisaenghyeolyunbueum (GSYE) is a traditional Oriental herbal medicine prescription, which has been used for the treatment of various allergic disorders, atopic dermatitis, extravasated bleeding from skin, especially skin related disease. The author investigated the effects of GSYE on mast cell-mediated allergic inflammatory reactions. GSYE dose-dependently (0.01-1 g/kg) inhibited compound 48180-induced systemic anaphylactic shock and ear swelling response. The inhibitory effect of GSYE on the histamine release from rat peritoneal mast cells induced by compound 48f80 reveals significantly (p<0.05) at concentrations ranging from 0.01 to 1 mg/ml in a dose-dependent manner. GSYE also inhibited the passive cutaneous anaphylaxis(PCA) by oral administration at 1 g/kg. In addition, GSYE dose-dependently (0.01-1 g/kg) inhibited the phorbol 12-myristate 13-acetate(PMA) and A23187-induced tumor necrosis $factor-{\alpha}$ secretion from human mast cell line HMC-1 cells. These results indicate that GSYE may be a beneficial applicability in the allergic-related diseases.

Objective : Moutan Cortex (the root bark of Paeonia suffruticosa Andr.) is widely used in oriental medicine as a remedy for inflammation. However, as yet there is no clear explanation of how MC(Moutan Cortex) affects the production of inflammatory cytokine. This study was to determine the effects of Essence extracted MC on the mast cell-mediated inflammatory responses. Method : We observed the effect of MC on compound 48/80-induced histamine release of rat peritoneal mast cells and the effect of administering MC on PCA in rat. 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 MC. The TNF-$\alpha$ protein levels were analysised by Western blot. 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. NF-$\kappa$B, phospho-I$\kappa$B and MAPKs were exmined by Western blot analysis. The NF-$\kappa$B promoter activity was examined by luciferase assay. Result : 1. Enzyme immunoassay indicated that MC suppressed histamine secretion of rat peritoneal mast cells. 2. In PCA dependent on IgE, MC had anti-allergic effect of the internal surface of rat skin. 3. Western blot indicated that MC decreased TNF-$\alpha$ protein levels. 4. ELISA indicated that MC decreased TNF-$\alpha$, IL-6 but MC had no significant effect on IL-8 in HMC-1 cells. 5. RT-PCR indicated that MC decreased TNF-$\alpha$, IL-8 but MC had no significant effect on IL-6 in HMC-l cells. 6. Western blot indicated that MC suppressed the induction of MAPKs, NF-$\kappa$B & phospho-I$\kappa$B activity in HMC-1 cells. 7. Luciferase assay indicated that MC suppressed the PMA plus A23187-induced NF-$\kappa$B promoting activityin HMC-1 cells. Conclusion : In this study, we have found that MC is an inhibitor of NF-$\kappa$B, MAPKs & cytokines on the mast cell-mediated inflammatory responses.

Acanthoic acid (AA) is a pimaradiene diterpene isolated from the Korean medicinal plant, Acanthopanax koreanum (Araliaceae), which has been traditionally used as a tonic and sedative as well as in the treatment of rheumatism and diabetes in korea. Proteinase-activated receptor-2 (PAR-2) agonist trypsin plays a role in inflammation, and human leukemic mast cells (HMC-l) express PAR-2. In the present study, the effect of acanthoic acid on production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and tryptase in trypsin-stimulated HMC-1 was examined. (omitted)

Luteolin is a major flavonoid of Lonicera japonica and has anti-inflammatory effect. The activation of proteinase-activated receptor (PAR)-2 and -4 by trypsin appears to play a role in inflammation, In the present study, we examined the inhibitory effects of luteolin on activation of trypsin-induced human leukemic mast cells (HMC-1). HMC-1 cells were stimulated with trypsin, PAR-2 and PAR-4 agonist, in the presence or absence of luteolin. The level of TNF-${\alpha}$ secretion was measured by enzyme-linked immunosorbent assay (ELISA). The expression of tryptase and phosphorylated-extracellular signal-regulated kinase (ERK) were assessed by Westem blot analysis. Moreover, trypsin activity was measured by the substrate Bz-DL-Arg-p-nitroanilide (BAPNA). TNF-${\alpha}$ secretion and Tryptase expression in trypsin-stimulated HMC-1 cells were markedly inhibited by pretreatment of luteolin. Furthermore, the pretreatment of luteolin resulted in the reduction of ERK phosphorylation and trypsin activity. These results suggest that luteolin might has the inhibitory effects on the PAR-2 and -4-dependent inflammation.

The purpose of this research was to investigate the effects of Kwakhyangjeonggisan (KJS) on the anti-allergic action. In the present study, we examined the effect of KJS on type I and type IV allergic reaction. KJS inhibited the systemic anaphylaxis induced by compound 48/80 and platelet activating factor (PAF), and inhibited the passive cutaneous anaphylaxis (PCA) induced by anti-dinitrophenyl (DNP)-IgE and DNP-human serum albumin (HSA) in vivo. In addition, KJS dose-dependently inhibited the release of histamine from peritoneal mast cells in rat. Also, KJS inhibited the delayed type hypersensitivity (DTH) induced by SRBC and the contact dermatitis induced by dinitrofluorobenzene (DNFB). KJS inhibited the proliferation of splenocytes, the subpopulation of B220+ cells and CD4+CD8-(Th) cells in splenocytes and the production of γ-interferon in serum and splenocytes. These findings suggest that KJS prevented the type I allergy by the inhibition of histamine release from mast cells and the type IV allergy by the inhibition of γ-interferon production and B lymphocytes subpopulation. These results indicate that KJS may be useful for the prevention and treatment of type I and type IV allergy related disease.

Mast cells and basophils perform important functions as pivotal effector cells in IgE-mediated allergic reactions. KU812F cells, a human basophilic cell line isolated originally from chronic myelocytic leukemia, express a high affinity receptor of IgE, $Fc{\varepsilon}RI$. Kaempferol was extracted and isolated from a methanolic extract of flavonoid-rich Nelumbo nucifera stamens. In the present study, the inhibitory effects of kaempferol on $Fc{\varepsilon}RI$ expression in human basophilic KU812F cells was examined. Flow cytometric analysis revealed that $Fc{\varepsilon}RI$ expression on the cell surface was suppressed in a concentration-dependent manner when the cells were cultured with kaempferol. Moreover, RT-PCR analysis showed that the mRNA levels for $Fc{\varepsilon}RI$ ${\alpha}-\;and\;{\gamma}$-chains were reduced as the result of kaempferol treatment in a concentration-dependent manner. Kaempferol showed its suppressive effects on intracellular $Ca^{2+}$ concentration and histamine release from anti-$Fc{\varepsilon}RI$ ${\alpha}$-chain antibody-stimulated cells in a concentration-dependent manner. These observations indicate that kaempferol may exert antiallergic effect via down regulation of $Fc{\varepsilon}RI$ expression and degranulation.

Black-red ginseng (BRGP) exhibits more potent biological activities than white and red ginseng. However, the effect of BRGP on allergic inflammation has not been studied extensively. In this study, we attempted to evaluate the effects of BRGP on allergic inflammation in vitro and in vivo. The effects of BRGP on pro-inflammatory mediators in phorbol myristate acetate (PMA) and A23187-stimulated human mast cells (HMC-1) and on trimellitic anhydride (TMA)-induced atopic dermatitis-like skin lesions in BALB/c mice were evaluated. BRGP suppressed the expression of $TNF-{\alpha}$, IL-6 and IL-8 from HMC-1 stimulated with PMA and A23187. Furthermore, the oral administration of BRGP markedly significantly reduced apparent severity of atopic dermatitis-like skin lesions, ear swelling, lymph node weight gains and serum IgE levels induced by TMA in mice. BRGP treatment also ameliorated epidermal hyperplasia and infiltration of inflammatory cells including mast cells. Taken together, BRGP possesses significant anti-atopic efficacy, suggesting that it could be used as a potential therapeutic agent for allergic inflammatory diseases, including atopic dermatitis.

Many previous studies have proved that human allergic disease resulted from the formation of antibodies belonging to a unique immunoglobulin isotype termed immunoglobulin E (IgE). Most of IgE-producing plasma cells are found in the lymphoid tissue associated with the gastrointestinal and respiratory tracts. IgE may be found free in the mucosal secretions of these tissues, bound to local mast cells, or distributed by the systemic circulation to mast cells and basophils throughout the body. Total serum IgE concentrations tend to be higher in allergic adults and children compared with non-allergic individuals, but the value of total serum IgE as a screening test for allergic disease is limited. Total serum IgE levels are related to the probability of an individual having detectable allergen-specific IgE. Allergen-specific IgE concentrations vary with a person's age, the degree and duration of the recent allergen or cross-reactive allergen exposure. The value of quantitative assays for allergen-specific IgE has been suggested in recent studies. Serum IgE increases in many non-allergic diseases, including infectious and parasitic diseases. The IgE changes appear to be specific to the infectious agents, whereas non-specific in other diseases. The increased serum IgE in some of these conditions probably results from alterations in immune function. This review summarizes the clinical significance of total and allergen-specific IgE examinations in allergic diseases.

Object : This study investigates Jaeumganghwa-tang(JGT) has been used for the purpose of prevention and treatment of allergic inflammatory diseases. This study was to investigate the biological effects of JGT. Methods : Cytotoxcicity and inflammatory cytokines secretion with human mast cells(HMC-1) were examined. HMC-1 cells were stimulated with phorbol l2-myristate 13-acetate (PMA) and calcium ionophore A23l87. JGT by itself had no effect on cytotoxicity of HMC-1. The effects of JGT on the secretion of tumor necrosis factor-alpha(TNF-${\alpha}$) and interleukin(IL)-6 from HMC-1 were evaluated with enzyme-linked immunosorbent assay(ELISA). Result : It was found that JGT inhibited PMA plus A23187-induced TNF-${\alpha}$ and IL-6 secretion. JGT also inhibited the $NF-{\kappa}$B(p50) expression. Conclusion : These results suggest that JGT inhibits the secretion of inflammatory cytokines in HMC-1 cells through blockade of $NF-{\kappa}B$ activation. Taken together, these effects support a role for JGT as a therapeutic agent in treatment of allergic inflammatory diseases such as asthma.

The purpose of this study was to investigate the anti-allergy activities of persimmon leaf extract (PLE) on a phthalic anhydride (PA)-induced allergic mouse model. A human leukemic mast cell line (HMC-1) was used to examine the inhibitory activity of PLE on the histamine release by human leukemic mast cells. PLE inhibited histamine release from HMC-1 cells in response to cross-linkage of high-affinity IgE receptor-${\alpha}$ ($Fc{\varepsilon}RI{\alpha}$). Additionally, a PA-induced allergic mouse model was used to investigate the effects of PLE in vivo. Mice were orally administrated with or without PLE of single dose (250 mg/kg/day) for 31 days. Oral intake of PLE significantly inhibited passive cutaneous reactions. Oral administration of PLE to PA-induced allergic mice also led to a striking suppression of the development of contact dermatitis, ear swelling and lymph node weight. In addition, PA-specific IL-4 production of draining lymph node cells was markedly diminished by PLE oral administration, but not IFN-${\gamma}$. Furthermore, PLE treatment suppressed PA-induced thymus and activation-regulated chemokine (CCL17) and cutaneous T cell-attracting chemokine (CCL27) expressions in ear tissues. Based on these results, we suggest that PLE may have therapeutic potential as an effective material for management of irritant contact dermatitis or related inflammatory diseases.
