Abstract
Inflammation is a protective immune response against invading pathogens, however, dysregulated inflammation is detrimental. As the complex inflammatory response involves multiple mediators, including the involvement of reactive oxygen species, concomitantly targeting proinflammatory and antioxidant check-points may be a more rational strategy. We report the synthesis and anti-inflammatory/antioxidant activity of a novel indanedione derivative DMFO. DMFO scavenged reactive oxygen species (ROS) in in-vitro radical scavenging assays and in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. In acute models of inflammation (carrageenan-induced inflammation in rat paw and air pouch), DMFO effectively reduced paw oedema and leucocyte infiltration with an activity comparable to diclofenac. DMFO stabilised mast cells (MCs) in in-vitro A23187 and compound 48/80-induced assays. Additionally, DMFO stabilised MCs in an antigen (ovalbumin)-induced MC degranulation model in-vivo, without affecting serum IgE levels. In a model of chronic immune-mediated inflammation, Freund's adjuvant-induced arthritis, DMFO reduced arthritic score and contralateral paw oedema, and increased the pain threshold with an efficacy comparable to diclofenac but without being ulcerogenic. Additionally, DMFO significantly reduced serum TNFα levels. Mechanistic studies revealed that DMFO reduced proinflammatory genes (IL1β, TNFα, IL6) and protein levels (COX2, MCP1), with a concurrent increase in antioxidant genes (NQO1, haem oxygenase 1 (HO-1), Glo1, Nrf2) and protein (HO-1) in LPS-stimulated macrophages. Importantly, the anti-inflammatory/antioxidant effect on gene expression was absent in primary macrophages isolated from Nrf2 KO mice suggesting an Nrf2-targeted activity, which was subsequently confirmed using siRNA transfection studies in RAW macrophages. Therefore, DMFO is a novel, orally-active, safe (even at 2 g/kg p.o.), a small molecule which targets Nrf2 in ameliorating inflammation.

Abstract
The discovery of drugs for the treatment of allergic disease is an important subject in human health. The Artemisia iwayomogi (Compositae) (AIE) has been used 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 AIE on the mast cell-mediated allergy model and studied the possible mechanism of action. AIE inhibited compound 48/80–induced systemic reactions and plasma histamine release in mice. AIE decreased immunoglobulin E (lgE)–mediated local allergic reaction, passive cutaneous anaphylaxis (PCA) reaction. AIE dose dependency attenuated histamine release from rat peritoneal mast cells activated by compound 48/80 or IgE. AIE decreased the compound 48/80-induced intracellular Ca2+. Furthermore, AIE decreased the phorbol 12-myristate 13-acetate (PMA) plus calcium lonophore A23187-stimulated tumor necrosis factor-α and interleukin-6 gene expression and production in human mast cells. The inhibitory effect of AIE on the proinflammatory cytokine was p38 mitogen-activated protein kinase (MAPK) and nuclear factor-κB (NF-κB) dependent. AIE attenuated PMA plus A23187-lnduced degradation of licBa and nuclear translocation of NF-κB and specifically blocked activation of p38 MAPK but not that of c-jun N-terminal kinase and extracellular signal-regulated kinase. Our findings provide evidence that AIE inhibits mast cell-derived immediate-type allergic reactions and involvement of Intracellular Ca2+, proinflammatory cytokines, p38 MAPK, and NF-κB in these effects.

Abstract
Yessotoxin (YTX) is a polyether compound produced by dinoflagellates and accumulated in filter feeding shellfish. No records about human intoxications induced by this compound have been published, however it is considered a toxin. Modifications in second messenger levels, protein levels, immune cells, cytoskeleton or activation of different cellular death types have been published as consequence of YTX exposure. This review summarizes the main intracellular pathways modulated by YTX and their pharmacological and therapeutic implications.

Abstract
HMC-1 are inflammatory cells that release vasoactive substances such as histamine. These cells have the c-kit receptor permanently activated in the membrane due to mutations in the proto-oncogene c-kit: Val-560 → Gly and Asp-816 → Val. Thus, there are two known cellular lines: HMC-1(560) and HMC-1(560,816) . These mutations are involved in a disease called mastocitosys. In the present paper both lines were used to study the influence of cAMP/PKA/PDEs pathway on the histamine release and Ca(2+) signaling since this pathway is often involved in these process. For this, the cells were preincubated with cAMP/PKA/PDEs modulators such as dibutyryl cAMP (dbcAMP), forskolin, H89, rolipram, IBMX, or imidazole and then stimulated with ionomycin. When cells were stimulated with agents that increase cAMP levels, the histamine release was not modified in HMC-1(560) but decreased in HMC-1(560,816) cells. The same happened when PKA was blocked. Furthermore, PDEs role on histamine release was independent of cAMP in HMC-1(560) cells and possibly also in HMC-1(560,816) cells. By contrast, the modulation of PKA and PDEs together changed the response in both cellular lines, therefore a relationship between them was suggested. All these modulatory effects on histamine release are Ca(2+) -independent. On the other hand, the effect of c-kit modulation on the cAMP/PKA/PDEs pathway was also checked. This receptor was blocked with STI571 (imatinib) and BMS-354825 (dasatinib), but only the last one caused a decrease in the cellular response to ionomycin. This article demonstrates for the first time than the cAMP/PKA/PDEs pathway is involved in the activation of HMC-1(560) and HMC-1(560,816) cells.

Abstract
BiRyuChe-bang (BRC) is a Korean prescription medicine, which has been used to treat allergic rhinitis at Kyung Hee Medical Center. In this work, we investigated the effects of BRC on mast cell-mediated allergic reactions and inflammatory cytokines production, and identified the active component of BRC. Histamine release was measured from rat peritoneal mast cells (RPMCs). Ear swelling and passive cutaneous anaphylaxis (PCA) were examined in mouse models. Phorbol 12-myristate 13-acetate (PMA) plus A23187-induced inflammatory cytokines production was measured using enzyme-linked immunosorbent assay. Reverse transcriptase-polymerase chain reaction was used for the expressions of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-8. Activation of nuclear factor (NF)-κB was analyzed by Western blotting. BRC significantly inhibited the compound 48/80-induced ear swelling response, histamine release from RPMCs, PCA activated by anti-dinitrophenyl IgE, and PMA plus A23187-induced inflammatory cytokines production (p < 0.05). In addition, BRC dose-dependently inhibited the mRNA expressions of TNF-α, IL-6, and IL-8 as well as the activation of NF-κB in a human mast cell line, HMC-1 cells. BRC inhibited the levels of TNF-α and IL-6 in mice induced with PCA. Several components of BRC, such as 1,8-Cineole, Linalool, Linalyl acetate, α-Pinene, and α-Terpineol, significantly inhibited the release of histamine from RPMCs (p < 0.05). Among these components, Linalyl acetate was the most effective for inhibiting histamine release. These results indicate that BRC has a potential regulatory effect on allergic and inflammatory reactions mediated by mast cells.

Abstract
Diospyros kaki (D. kaki) has been cultivated throughout Eastern Asia for hundreds of years. D. kaki contains various biological active compounds, such as amino acids, carotenoids, flavonoids, tannins, catechins and vitamin A. Previous studies have shown that D. kaki has beneficial effects on homeostasis, constipation, hypertension, atherosclerosis and allergic dermatitis and is a good source of antioxidants, polyphenols and dietary fiber. However, the anti-allergic and anti-inflammatory effects of D. kaki have not yet been elucidated. This study aimed to investigate the protective effects of the aqueous extract of Diospyros kaki (AEDK) on mast cell-mediated allergic inflammation and to determine its possible mechanisms of action by using in vitro and in vivo mast cell-based models. The cAMP and intracellular calcium levels were measured to clarify the mechanisms by which AEDK inhibits the release of histamine from mast cells. AEDK inhibited the release of histamine and β-hexosaminidase from mast cells by modulating cAMP and intracellular calcium levels. We also measured the expression of pro-inflammatory cytokines, such as tumor necrosis factor (TNF)-α and interleukin (IL)-1β. AEDK decreased gene expression and the secretion of the pro-inflammatory cytokines, TNF-α and IL-1β by inhibiting nuclear factor-κB. In addition, AEDK inhibited systemic and cutaneous allergic reaction. The inhibitory effects of AEDK on allergic reaction and the release of histamine were found to be similar to those of disodium cromoglycate, a known anti-allergic drug. To isolate the active component of AEDK, activity-guided fractionation was performed, based on the inhibitory effects on systemic anaphylaxis. Catechin was identified as an active compound. The present findings provide evidence that AEDK inhibits allergic inflammation and suggest the therapeutic application of AEDK in allergic inflammatory disorders.

Abstract
It has become widely accepted that the role of mast cells is not restricted to allergic processes. Thus, mast cells play an important role in innate and adaptive immune responses, but study of proteins related to differentiation of mast cells has not been done yet. Enolase 1 is a glycolytic enzyme expressed in most tissues and calreticulin, known as endoplasmic reticulum (ER) resident chaperon, has multifunctional responses. This study aimed to investigate the effects of these proteins on the differentiation and functions of mouse bone marrow-derived mast cells (BMMCs). To identify the target proteins related to the differentiation of BMMCs, we examined the protein expression pattern of BMMCs using 2-dimensional electrophoresis (2-DE) and MALDI-TOF analysis. Expressions of FcεRIα, surface molecules (c-kit, CD40, CD40L, VCAM-1), tryptase, and cytokines were examined in BMMCs using FACS analysis, Western blot, and RT-PCR respectively. Enolase 1 and calreticulin were transfected into BMMCs, and [Ca(2+)]i levels were determined by confocal microscope, while amounts of TNF-α and LTs were measured by ELISA. Eight proteins were identified by proteomic analysis. Enolase and calreticulin siRNA transfection inhibited the expressions of FcεRIα, surface molecules, tryptase, and cytokine mRNA, which are gradually enhanced during culture periods of BMMCs. Enolase 1 and calreticulin siRNA reduced the [Ca(2+)]i levels, amounts of total TNF-α, and the release of TNF-α and leukotrienes, all of which are increased in the BMMCs activated with antigen/antibody reaction. The data suggest that enolase 1 and calreticulin are important proteins in regulating the differentiation and functions of BMMCs.

Abstract
Allergic disease is a consequence of exposure to normally innocuous substances that elicit the activation of mast cells. Mast-cell-mediated allergic response is involved in many diseases such as anaphylaxis, allergic rhinitis, asthma and atopic dermatitis. The discovery of drugs for the treatment of allergic disease is an important subject in human health. In this study, we investigated the effect of Lindera obtusiloba water extract (LOWE) on the mast-cell-mediated allergic inflammation and possible mechanism of action using in vitro and in vivo models. LOWE reduced histamine release from various types of mast cells activated by immunoglobulin E (IgE) or phorbol 12-myristate 13-acetate and calcium ionophore A23187 (PMACI). The inhibitory effect of LOWE on histamine release was mediated by calcium signal. LOWE decreased the PMACI-stimulated gene expression of proinflammatory cytokines such as tumor necrosis factor-α and interleukin-6 in human mast cells. The inhibitory effect of LOWE on the proinflammatory cytokines was nuclear factor (NF)-κB dependent. In addition, LOWE suppressed compound 48/80-induced systemic allergic reaction and serum histamine release in mice and IgE-mediated local allergic reactions. Our results indicate that LOWE inhibits mast-cell-derived allergic inflammation and involvement of calcium, histamine, proinflammatory cytokines and NF-κB in these effects.

Abstract
In this study, we investigated the effect of the Meoruh wine (MW), a Korean traditional wine made by the fruits of Vitis amurensis Rupr. (Vitaceae) on the mast cell-mediated allergic inflammation and studied the possible mechanism of action. Mast cell-mediated allergic disease is involved in many diseases such as anaphylaxis, rhinitis, asthma, and atopic dermatitis. MW inhibited compound 48/80-induced systemic anaphylaxis and serum histamine release in a dose-dependent manner in mice. MW decreased immunoglobulin E-mediated local allergic reactions, passive cutaneous anaphylaxis. MW dose-dependently reduced histamine release from human mast cells activated by phorbol 12-myristate 13-acetate and calcium ionophore A23187 (PMACI). The inhibitory effect of MW on histamine release was mediated by suppression of intracellular calcium. In addition, MW attenuated the PMACI-stimulated expression of pro-inflammatory cytokines such as tumor necrosis factor-α, interleukin-1β (IL-1β), IL-6, and IL-8 in human mast cells. The inhibitory effect of MW on these pro-inflammatory cytokines was nuclear factor (NF)-κB dependent. Our findings provide evidence that MW inhibits mast cell-derived allergic inflammatory reactions and involvement of calcium, pro-inflammatory cytokines and NF-κB in these effects.

Abstract
Chlorogenic acid (CGA), a naturally occurring polyphenol compound, has a number of biological activities. However, roles of CGA in the mast cell-dependent anaphylactic reaction have not been fully examined. In the present study, the effect and mechanism of CGA on mast cell-dependent anaphylactic reaction were investigated using in vivo and in vitro models. CGA inhibited compound 48/80-induced systemic anaphylactic shock in mice and skin vascular permeability in rats. CGA also inhibited anti-dinitrophenyl (DNP) IgE-mediated passive cutaneous anaphylaxis (PCA). Moreover, CGA dose-dependently reduced histamine and TNF-alpha release from RBL-2H3 cells activated by anti-DNP IgE. Pretreatment with CGA suppressed IgE-antigen complex induced calcium uptake into RBL-2H3 cells. When CGA was added, the level of intracellular cyclic adenosine monophosphate (cAMP) in RBL-2H3 cells was significantly elevated compared with the untreated cells. Decreased calcium uptake and increased cAMP level might be involved in the inhibitory effect of CGA on mast cell activation. These results suggest a possible therapeutic application of CGA in allergic diseases.

Mast cell-mediated allergic disease is involved in many diseases such as anaphylaxis, rhinitis, asthma and atopic dermatitis. The discovery of drugs for the treatment of allergic disease is an important subject in human health. In this study, we investigated the effect of the water extract of Clinopodium gracile Matsum var. multicaule (WECG) on the mast cell-mediated allergic inflammation and studied the possible mechanism of action. WECG inhibited compound 48/80-induced systemic anaphylaxis and immunoglobulin E-mediated cutaneous anaphylaxis in a dose-dependent manner. WECG dose-dependently reduced histamine release from rat peritoneal mast cells and human mast cells. The inhibitory effect of WECG on histamine release was mediated by the modulation of intracellular calcium. In addition, WECG attenuated the phorbol 12-myristate 13-acetate and calcium ionophore A23187-stimulated gene expression and secretion of proinflammatory cytokines such as tumor necrosis factor-alpha and interleukin-6 in human mast cells. The inhibitory effect of WECG on these proinflammatory cytokines was nuclear factor-kappaB (NF-kappaB) dependent. Our findings provide evidence that WECG inhibits mast cell-derived allergic inflammation and involvement of calcium and NF-kappaB in these effects.

Abstract
Abstract
The effect of extracts from various Oriental medicinal herbs on mast-cell-mediated allergic reactions was investigated in this study. Of these extracts, the medicinal herb Rubiae Radix exhibited the most potent activity in the cells, with an IC50 value (concentration necessary to obtain 50% inhibition of the response) of approximately 35±2.1 μg mL−1, and its inhibition of compound-48/80-induced systemic anaphylaxis by 48.6±8.5% at 300 mg kg−1 in mice. It also inhibited the expression of the pro-inflammatory mediator tumour necrosis factor-α (TNF-α). As for its mechanism of action, Rubiae Radix suppressed the activating phosphorylation of Syk, a key enzyme in mast-cell signalling processes, and that of Akt in a dose-dependent manner. It also inhibited the MAP kinase ERK1/2, which is critical for the production of inflammatory cytokines in mast cells, as indicated by the suppression of the activating phosphorylation of ERK1/2. These results suggest that Rubiae Radix suppresses the activation of mast cells through the inhibition of Syk for antiallergic activity.

Abstract
Abstract
The effects of various extracts from oriental medicinal herbs on mast cell-mediated allergic reactions have been investigated. Among the extracts, Arecae semen was the most potent inhibitor of antigen-induced degranulation in RBL-2H3 mast cells. A. semen inhibited DNP-BSA- and compound 48/80-induced degranulation in RBL-2H3 mast cells with IC50 values of approximately 53 and 52 μg mL−1, respectively, and inhibited compound 48/80-induced systemic anaphylaxis by 46% at 300 mg kg−1 in mice. A. semen also inhibited the expression of TNF-α and the activation of mitogen activated protein kinase, ERK1/2, which is critical for the production of inflammatory cytokines in mast cells, as indicated by the suppression of the activating phosphorylation of ERK1/2. These results suggest that A. semen may be useful for the treatment of various immediate and delayed allergic diseases.

Abstract
Silibinin is known to have hepatoprotective, anti-carcinogenic and anti-inflammatory effects. However, roles of silibinin in the immediate-type allergic reactions (anaphylaxis) have not fully been investigated. In the present study, we have demonstrated that silibinin attenuated mast cell-mediated anaphylaxis-like reactions involved in allergic diseases. Oral administration of silibinin inhibited compound 48/80-induced passive cutaneous anaphylaxis-like reaction in mice. Silibinin also attenuated anti-dinitrophenyl (DNP) immunoglobulin (Ig) E-mediated passive systemic and cutaneous anaphylaxis. Silibinin had no cytotoxicity on rat peritoneal mast cells (RPMC). Silibinin dose-dependently reduced histamine release from RPMC activated by compound 48/80 or anti-DNP IgE. Moreover, silibinin inhibited the secretion of pro-inflammatory cytokines, such as tumor necrosis factor-alpha and interleukin-6 in RPMC. Pretreatment of silibinin suppressed the antigen-stimulated calcium uptake and activation of nuclear factor-kappa B (NF-kappaB) in RPMC. Furthermore, silibinin increased the intracellular cAMP level. Increased cAMP, decreased calcium uptake and suppressed NF-kappaB activity might be involved in the inhibitory effect of silibinin on the secretory response. Our findings provide possibility that silibinin may serve as an effective therapeutic agent for allergic diseases.

Abstract
The objective of the present study was to investigate the effects of saponins from the anomalous fruits of Gleditsia sinensis on mast cell degranulation triggered by compound 48/80 and to determine possible structure-activity relationships. Among the eleven saponins tested, four effectively inhibited β-hexosaminidase release from rat peritoneal mast cells. Studies of structure-activity relationships indicated that saponins with an aglycone of echinocystic acid instead of oleanolic acid were more effective. A sugar chain at C-3 was essential for the inhibitory effects, and a single sugar chain was the most effective. The length and structures of the oligosaccharide chain at C-28 were also critical for the activity of the compounds, and introduction of monoterpene units to the oligosaccharide chain substantially decreased the activity. To gain insight into the mechanisms responsible for preventing mast cell degranulation, the effects of saponins on intracellular cAMP were examined. After preincubation with mast cells for different times, the four active saponins significantly increased the intracellular cAMP content. These findings suggested that the four saponins might be the active constituents of the anomalous fruits of G. sinensis for antiallergic activities, and they prevented mast cell degranulation probably by elevating intracellular cAMP levels.

Abstract
The mast cell-mediated immediate-type allergic reaction is involved in many allergic diseases such as asthma, allergic rhinitis, and sinusitis. Stimulation of mast cells starts the process of degranulation resulting in release of mediators such as histamine and an array of inflammatory cytokines. In this report, we investigated the effect of aqueous extract of Teucrium japonicum Houttuyn (Labiatae) (AXTJ) on the mast cell-mediated allergy model and studied its possible mechanisms of action. AXTJ inhibited compound 48/80-induced systemic reactions and serum histamine release in mice. AXTJ decreased immunoglobulin E-mediated passive cutaneous anaphylaxis reaction. AXTJ reduced histamine release and intracellular calcium from rat peritoneal mast cells activated by compound 48/80. In addition, AXTJ attenuated activation of nuclear factor (NF)-kappaB, and downstream tumor necrosis factor (TNF)-alpha expression in phorbol 12-myristate 13-acetate and calcium ionophore A23187-stimulated human mast cells. Our findings provide evidence that AXTJ inhibits mast cell-derived allergic reactions and involvement of intracellular calcium, TNF-alpha, and NF-kappaB in these effects.

Abstract
Mast cells participate in allergy and inflammation by secreting inflammatory mediators such as histamine and proinflammatory cytokines. Flavonoids are naturally occurring molecules with antioxidant, cytoprotective, and antiinflammatory actions. However, effect of flavonoids on the release of histamine and proinflammatory mediator, and their comparative mechanism of action in mast cells were not well defined. Here, we compared the effect of six flavonoids (astragalin, fisetin, kaempferol, myricetin, quercetin, and rutin) on the mast cell-mediated allergic inflammation. Fisetin, kaempferol, myricetin, quercetin, and rutin inhibited IgE or phorbol-12-myristate 13-acetate and calcium ionophore A23187 (PMACI)-mediated histamine release in RBL-2H3 cells. These five flavonoids also inhibited elevation of intracellular calcium. Gene expressions and secretion of proinflammatory cytokines such as tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-1beta, IL-6, and IL-8 were assessed in PMACI-stimulated human mast cells (HMC-1). Fisetin, quercetin, and rutin decreased gene expression and production of all the proinflammatory cytokines after PMACI stimulation. Myricetin attenuated TNF-alpha and IL-6 but not IL-1beta and IL-8. Fisetin, myricetin, and rutin suppressed activation of NF-kappaB indicated by inhibition of nuclear translocation of NF-kappaB, NF-kappaB/DNA binding, and NF-kappaB-dependent gene reporter assay. The pharmacological actions of these flavonoids suggest their potential activity for treatment of allergic inflammatory diseases through the down-regulation of mast cell activation.

Abstract
The effect of an aqueous extract of Phlomis umbrosa Turcz. (Labiatae) root (PUAE) on mast cell-dependent allergic reactions and inflammatory cytokine secretion were investigated. PUAE (0.01-1 g/kg) inhibited compound 48/80-induced systemic allergic reaction. When PUAE was employed in a systemic allergic reaction test, the plasma histamine levels were reduced in a dose-dependent manner. PUAE (0.1 and 1 g/kg) also significantly inhibited the local allergic reaction activated by anti-dinitrophenyl (DNP) IgE. PUAE (0.001-1 mg/mL) dose-dependently inhibited the histamine release from rat peritoneal mast cells activated by compound 48/80 or anti-DNP IgE. PUAE (0.01-1 mg/mL) inhibited the secretion of interleukin (IL)-1beta in phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated human mast cell line (HMC-1) cells. PUAE (1 mg/mL) inhibited the gene expression and production of the main inflammatory cytokine, TNF-alpha, in HMC-1 cells. These results provide evidence that PUAE may be beneficial in the treatment of allergic diseases.

Abstract
In this study, we investigated the effect of the methanol extract of fruits of Vitis amurensis Rupr. (Vitaceae; MEVA) on the mast cell-mediated allergy model and studied the possible mechanism of action. Mast cell-mediated allergic disease is involved in many diseases, such as asthma and sinusitis. The discovery of drugs for the treatment of allergic disease is an important subject in human health. MEVA inhibited compound 48/80-induced systemic reactions and serum histamine release in a dose-dependent manner in mice. MEVA decreased immunoglobulin E (IgE)-mediated local allergic reactions, passive cutaneous anaphylaxis. MEVA dose-dependently reduced histamine release from mast cells activated by compound 48/80 or IgE. The inhibitory effect of MEVA on histamine release was mediated by the modulation of intracellular calcium. In addition, MEVA attenuated the phorbol 12-myristate 13-acetate and calcium ionophore A23187 (PMACI)-stimulated secretion of tumor necrosis factor-alpha, interleukin-6 (IL-6), and IL-8 in human mast cells. The inhibitory effect of MEVA on these proinflammatory cytokines was p38 mitogen-activated protein kinase and nuclear factor-kappaB (NF-kappaB) dependent. Our findings provide evidence that MEVA inhibits mast cell-derived, immediate-type allergic reactions and involvement of proinflammatory cytokines, p38 MAPK, and NF-kappaB in these effects.

Abstract
To explore effects of Forsythia koreana methanol extract (FKME) on mast cell-mediated allergic and inflammatory properties, the effect of FKME was evaluated on compound 48/80-induced systemic anaphylaxis, ear swelling, and anti-dinitrophenyl (DNP) immunoglobulin E (IgE)-induced passive cutaneous anaphylaxis (PCA). In addition, the effect of FKME was investigated on the histamine release from rat peritoneal mast cells (RPMCs) stimulated by compound 48/80, which promotes histamine release. The human mast cell line HMC-1 was stimulated by phorbol 12-myristate 13-acetate plus calcium ionophore A23187. Activated HMC-1 can produce several proinflammatory and chemotactic cytokines such as tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-6, and IL-8. Cytokine levels in the culture supernatant were measured by an enzyme-linked immunosorbent assay. Cytotoxicity by FKME was determined by a 3-(4,5-dimethylthiazol-2-yl)-diphenyl-tetrazolium bromide (MTT) assay. FKME inhibited compound 48/80-induced systemic anaphylactic shock and ear swelling in mice. When 1 g/kg FKME was pretreated or posttreated with mice, compound 48/80-induced mice morality was 50 and 66.7%, respectively. One gram per kilogram of FKME pretreatment inhibited ear-swelling responses derived from compound 48/80 by 29.75%. A PCA reaction was inhibited by 17.9%. In an in vitro model, FKME (1 mg/ml) inhibited histamine release from the RPMCs by 13.8% and TNF-alpha, IL-6, and IL-8 production from HMC-1 cells by 71.16% (P < 0.001), 86.72% (P < 0.001), and 44.6%, respectively. However, FKME had no cytotoxic effects on cell viability. In conclusion, FKME inhibited not only systemic anaphylaxis and ear swelling induced by compound 48/80 but also inhibited a PCA reaction induced by anti-DNP IgE in vivo. Treatment with FKME showed significant inhibitory effects on histamine, TNF-alpha, IL-6, and IL-8 release from mast cells.

Stimulation of mast cells starts the process of degranulation resulting in release of mediators such as histamine and an array of inflammatory cytokines. In this report, we investigated the effect of aqueous extract of Amomum xanthiodes (Zingiberaceae) (AXE) on the mast cell-mediated allergy model and studied its possible mechanisms of action. AXE inhibited compound 48/80-induced systemic reactions and serum histamine release in mice. AXE decreased immunoglobulin E (IgE)-mediated passive cutaneous anaphylaxis reaction. AXE reduced histamine release and intracellular calcium from rat peritoneal mast cells activated by compound 48/80. Furthermore, AXE decreased the activation of p38 mitogen-activated protein kinase (MAPK) but not extracellular signal-regulated kinase and c-jun N-terminal kinase, and downstream tumor necrosis factor (TNF)-alpha production in phorbol 12-myristate 13-acetate and calcium ionophore A23187-stimulated human mast cells. Our findings provide evidence that AXE inhibits mast cell-derived allergic reactions, and that intracellular calcium, TNF-alpha, and p38 MAPK are involved in these effects.

Abstract
The anti-allergic action of various Oriental medicinal herbs was investigated using in vitro and in vivo experimental models. Of these extracts, the ethanol extract of Meliae cortex (MC) exhibited the most potent activity in mast cells; its IC(50) values were 29+/-1.5 microg/ml for antigen stimulation and 57+/-3.4 microg/ml for thapsigargin stimulation. It inhibited compound-48/80-induced systemic anaphylaxis by 52.9% at a dose of 300 mg/kg in mice; it also inhibited the expression of the proinflammatory mediator TNF-alpha. With regard to its mechanism of action, MC suppressed the activating phosphorylation of Syk, a key enzyme in mast-cell signaling processes and that of Akt in a dose-dependent manner. It also inhibited the MAP kinase ERK1/2, which is critical for the production of inflammatory cytokines in mast cells, as indicated by the suppression of the activating phosphorylation of ERK1/2. Taken together, these results suggest that the anti-allergic activity of MC may be due to the inhibition of histamine secretion and cytokine expression through the Syk inhibition in mast cells.

Abstract
OBJECTIVE Electroacupuncture (EA) has been used to treat myalgia, allergy and gastroenteropathy in Korea. To determine whether EA can treat anaphylactic and inflammatory reactions, the effect of EA was investigated in a murine model. METHODS EA stimulation of the ST36 acupoint was performed for 10 min. Using a passive cutaneous anaphylaxis (PCA) model, the antianaphylactic effects of EA were examined. Interleukin-6 and tumor necrosis factor-alpha were measured using the ELISA method. The level of nuclear factor (NF)-kappaB/RelA protein and NF-kappaB DNA-binding activity was determined using the Western blot analysis and the transcription factor enzyme-linked immunoassay method. RESULTS EA inhibits PCA and beta-hexosaminidase release, IL-6 secretion on the PCA, and in addition, EA reduces NF-kappaB DNA-binding activity. CONCLUSION These results indicate that EA may possess antianaphylactic and antiinflammatory properties.

Abstract
Mast cell-mediated anaphylactic reaction is involved in many allergic diseases such as asthma and allergic rhinitis. Phellinus linteus has been used as a traditional herb medicine in oriental countries and is known to have anti-tumor, immunomodulatory, anti-inflammatory, and anti-allergic activities. However, roles of Phellinus linteus in the mast cell-mediated anaphylactic reactions have not fully been examined. In the present study, we have investigated the effects of water extract from the fruiting body of Phellinus linteus (WEPL) on mast cell-mediated anaphylaxis-like reactions. Oral administration of WEPL inhibited the compound 48/80-induced systemic anaphylaxis-like reaction and ear swelling response. WEPL also inhibited the anti-dinitrophenyl (DNP) IgE-mediated passive systemic and cutaneous anaphylaxis. WEPL had no cytotoxicity on rat peritoneal mast cells (RPMC). WEPL dose-dependently reduced histamine release from RPMC activated by compound 48/80 or anti-DNP IgE. Moreover, WEPL decreased the compound 48/80-induced calcium uptake into RPMC. Furthermore, WEPL increased the level of intracellular cAMP and significantly inhibited the compound 48/80-induced cAMP reduction in RPMC. These results suggest that WEPL may serve as an effective therapeutic agent for allergic diseases.

Abstract
We investigated the effects of hot-water extract from the root bark of Morus alba (HEMA) on anaphylactic reactions. Using in vitro and in vivo experiments, we examined whether HEMA could inhibit compound 48/80-induced systemic anaphylactic shock and anti-chicken gamma globulin (CGG) IgE-mediated rat peritoneal mast cell activation. HEMA significantly inhibited systemic anaphylaxis induced by the compound 48/80 in mice. HEMA also significantly inhibited the passive cutaneous anaphylaxis activated by anti-CGG IgE. HEMA had no cytotoxicity on rat peritoneal mast cells (RPMC). Moreover, HEMA dose-dependently inhibited mast cell degranulation, histamine release and calcium uptake into RPMC induced by the compound 48/80 or anti-CGG IgE. When HEMA was added, the level of intracellular cAMP in RPMC showed a transient and significant increase (5-fold) compared with that of control cells. HEMA also inhibited significantly the compound 48/80-induced cAMP reduction in RPMC. These results suggested that HEMA inhibits the compound 48/80- or anti-CGG IgE-induced mast cell activation and its inhibitory effects on mast cell activations were favorably comparable to disodium cromoglycate. And HEMA is a candidate for effective therapeutic tools of allergic diseases.

Abstract
The present study was investigated the effect of Houttuynia cordata THUNB water extract (HCWE) on mast cell-mediated anaphylactic reactions. The mast cell-mediated anaphylactic reaction is involved in many allergic diseases such as asthma and allergic rhinitis. HCWE has been used as a traditional medicine in Korea and is known to have an antioxidant and anti-cancer activities. However, its specific effect of mast cell-mediated anaphylactic reactions is still unknown. We examined whether HCWE could inhibit compound 48/80-induced systemic anaphylaxis, IgE-mediated passive cutaneous anaphylaxis (PCA), and mast cell activation. The oral administration of HCWE inhibited compound 48/80-induced systemic anaphylaxis in mice. HCWE also inhibited the local allergic reaction, PCA, activated by anti-dinitrophenyl (DNP) IgE antibody in rats. HCWE reduced the compound 48/80-induced mast cell degranulation and colchicine-induced deformation of rat peritoneal mast cells (RPMC). Moreover, HCWE dose-dependently inhibited histamine release and calcium uptake of RPMC induced by compound 48/80 or anti-DNP IgE. HCWE increased the level of intracellular cAMP and inhibited significantly the compound 48/80-induced cAMP reduction in RPMC. These results suggest that HCWE may be beneficial in the treatment of mast cell-mediated anaphylactic responses.

Abstract
BACKGROUND Stimulation of mast cells starts the process of degranulation resulting in release of mediators such as histamine and an array of inflammatory cytokines. In this report, we investigated the effect of an aqueous extract of Dracocephalum argunense Fisch. (Labiatae) (DAAE) on immediate-type hypersensitivity and studied its possible mechanisms of action, focusing on histamine release and proinflammatory cytokine expression in mast cells. METHODS An in vivo model of systemic and local allergic reaction was investigated. Compound 48/80- or IgE-induced histamine release from mast cells was measured. The expression of proinflammatory cytokines such as TNF-alpha and IL-6 was measured by RT-PCR and ELISA. The level of intracellular calcium was measured by spectrofluorometry. NF-kappaB activation was measured by Western blot, EMSA and luciferase assay. RESULTS DAAE inhibited systemic anaphylaxis, local allergic reactions, and serum histamine release in a dose-dependent manner in mice. DAAE dose-dependently reduced histamine release from mast cells activated by compound 48/80 or IgE. The inhibitory effect of DAAE on histamine release was mediated by the modulation of intracellular calcium. In addition, DAAE decreased TNF-alpha and IL-6 gene expression and production in human mast cells stimulated by phorbol-12-myristate-13-acetate (PMA) plus calcium ionophore A23187. The inhibitory effect of DAAE on the TNF-alpha and IL-6 expression was NF-kappaB dependent. CONCLUSION Our findings provide evidence that DAAE inhibits mast-cell-derived immediate-type hypersensitivity. Taken together, the anti-allergic effect of DAAE in vivo and in vitro suggests a possible clinical use of this agent in immediate-type hypersensitivity.

Abstract
The discovery of drugs for the treatment of inflammatory allergic diseases such as, asthma, allergic rhinitis, and sinusitis is a very important subject in human health. Gallic acid (3,4,5-trihydroxybenzoic acid), a polyphenyl natural products from gallnut and green tea, is known to have anti-oxidant, anti-inflammatory, anti-microbial, and radical scavenging activities. The aim of the present study was to elucidate whether gallic acid modulates the inflammatory allergic reaction and to study its possible mechanisms of action. Gallic acid attenuated compound 48/80- or immunoglobulin E (IgE)-induced histamine release from mast cells. The inhibitory effect of gallic acid on the histamine release was mediated by the modulation of cAMP and intracellular calcium. Gallic acid decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated pro-inflammatory cytokine gene expression and production such as TNF-alpha and IL-6 in human mast cells. The inhibitory effect of gallic acid on the pro-inflammatory cytokine was nuclear factor-kappaB and p38 mitogen-activated protein kinase dependent. In addition, gallic acid inhibited compound 48/80-induced systemic allergic reaction and IgE-mediated local allergic reaction. The inhibitory activity of gallic acid on the allergic reaction and histamine release was found to be similar with disodium cromoglycate. Our findings provide evidence that gallic acid inhibits mast cell-derived inflammatory allergic reactions by blocking histamine release and pro-inflammatory cytokine expression, and suggest the mechanisms of action. Furthermore, in vivo and in vitro anti-allergic effect of gallic acid suggests a possible therapeutic application of this agent in inflammatory allergic diseases.

Abstract
In this study, we investigated the effect of Amomum xanthiodes (Zingiberaceae) extract (AXE) on the mast cell-mediated allergy model and studied the possible mechanism of action. We found that AXE inhibited compound 48/80-induced systemic reactions and plasma histamine release in mice. Additionally, AXE decreased immunoglobulin E (IgE)-mediated local allergic reactions and passive cutaneous anaphylaxis (PCA), and AXE dose-dependently attenuated the release of histamine from rat peritoneal mast cells (RPMC) activated by compound 48/80 or IgE. The amounts of AXE needed for inhibition of compound 48/80-induced plasma histamine release and PCA were similar to disodium cromoglycate, the known anti-allergic drug. We found that AXE increased the cAMP levels and decreased the compound 48/80-induced intracellular Ca2+. Furthermore, AXE attenuated the phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore (A23187)-stimulated tumor necrosis factor-alpha (TNF-alpha) and interleukin (IL)-6 secretion in human mast cells. The inhibitory effect of AXE on the proinflammatory cytokines was nuclear factor-kappaB (NF-kappaB)-dependent. In addition, AXE decreased PMA plus A23187-induced degradation of IkappaBalphaand the nuclear translocation of NF-kappaB. Our findings provide evidence that AXE inhibits mast cell-derived immediate-type allergic reactions, and that cAMP, intracellular Ca2+, proinflammatory cytokines, and NF-kappaB are involved in these effects.

Abstract
BACKGROUND Mast cells are key effector cells in the early-phase allergic inflammation and in diverse immunological and pathological processes. Sopoongsan (SPS), a traditional Korean medicine, has been used as therapeutics for allergic diseases such as atopic dermatitis (AD). The precise effect in experimental models of SPS, however, remains unknown. In this report, we investigated the effect of SPS on mast cell-mediated anaphylactic reactions and cytokine production in in vivo and in vitro murine models. METHODS Compound 48/80-induced histamine and ear swelling were measured with the various concentrations of SPS. The amount of dye was determined colorimetrically after antidinitrophenyl IgE antibody-induced passive cutaneous anaphylaxis reaction. Secretion of tumor necrosis factor-alpha (TNF-alpha), interleukin-8 (IL-8) and IL-6 in supernatants from HMC-1 cells was measured by a sandwich enzyme-linked immunosorbent assay. The expression level of nuclear factor (NF)-kappaB/Rel A in the nucleus and the activation of mitogen-activated protein kinases (MAPKs) were examined by Western blot analysis. RESULTS SPS inhibited the degranulation and histamine release from the rat peritoneal mast cells activated by compound 48/80. Compound 48/80-induced ear swelling was significantly reduced. SPS also showed an inhibitory effect of passive cutaneous anaphylaxis reaction. Significantly reduced levels (p < 0.05) of TNF-alpha, IL-8 and IL-6 were observed in the human mast cell line with SPS and SPS components. In addition, SPS inhibited an increase of NF-kappaB and extracellular signal-regulated kinase 1/2 activity. CONCLUSIONS These findings suggest that SPS has an inhibitory effect on atopic allergic reaction and this might be useful for the clinical application to treat allergic diseases such as AD.

Abstract
Cannabinoids are broadly immunosuppressive, and anti-inflammatory properties have been reported for certain marijuana constituents and endogenously produced cannabinoids. The CB2 cannabinoid receptor is an established constituent of immune system cells, and we have recently established that the CB1 cannabinoid receptor is expressed in mast cells. In the present study, we sought to define a role for CB1 in mast cells and to identify the signalling pathways that may mediate the suppressive effects of CB1 ligation on mast cell activation. Our results show that CB1 and CB2 mediate diametrically opposed effects on cAMP levels in mast cells. The observed long-term stimulation of cAMP levels by the Galpha(i/o)-coupled CB1 is paradoxical, and our results indicate that it may be attributed to CB1-mediated transcriptional regulation of specific adenylate cyclase isoenzymes that exhibit superactivatable kinetics. Taken together, these results reveal the complexity in signalling of natively co-expressed cannabinoid receptors and suggest that some anti-inflammatory effects of CB1 ligands may be attributable to sustained cAMP elevation that, in turn, causes suppression of mast cell degranulation.

Abstract
The immediate-type allergic reaction (anaphylaxis) is involved in many allergic diseases such as asthma, allergic rhinitis and sinusitis. We investigated the effect of the gall of Rhus javanica (GRJ) on the model of the immediate-type allergic reaction, and studied its possible mechanisms. GRJ inhibited compound 48/80-induced systemic reactions in mice. GRJ attenuated immunoglobulin (Ig) E-mediated local allergic reactions. In addition, GRJ dose dependently decreased histamine release from rat peritoneal mast cells activated by compound 48/80 or IgE. The decreasing effect of GRJ on the histamine release was mediated by the modulation of cAMP and [Ca2+]i in mast cells. Furthermore, GRJ decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated TNF-alpha and IL-6 secretion in human mast cells. The inhibitory effect of GRJ on the pro-inflammatory cytokine was c-Jun N-terminal kinase and nuclear factor-kappaB dependent. Our findings provide evidence that GRJ inhibits mast cell-derived immediate-type allergic reactions, and suggest the possible mechanisms of action.

Abstract
A human mast cell line (HMC-1) has been used to study the effect of cytosolic alkaline pH in exocytosis. Compound 48/80, concanavalin A, and thapsigargin do not induce histamine release in HMC-1 cells. Although thapsigargin does not activate histamine release, it does show a large increase in cytosolic Ca(2+), and no change in cytosolic pH. However, when HMC-1 cells were activated with ionomycin, a significant histamine release takes place, and this effect is higher in the presence of thapsigargin. Both drugs show an additive effect on cytosolic Ca(2+) levels. Ammonium chloride (NH(4)Cl) does activate cytosolic alkalinization and histamine release, with no increase in cytosolic Ca(2+). NH(4)Cl does block the release of internal Ca(2+) by thapsigargin, not by ionomycin, and decreases Ca(2+) influx stimulated by these drugs. Under conditions in which the alkalinization induced by NH(4)Cl is blocked by acidification with sodium propionate, histamine release is inhibited. The release of histamine is also observed when NH(4)Cl is added after propionate addition, regardless of the final pH value attained. Our results show that a shift in pH alkaline values, even with final pH below 7.2 is enough to activate histamine release. A shift to less acidic values is a sufficient signal to activate the cells.

Abstract
Alkalinization of cytosolic pH with ammonium chloride (NH4Cl) was reported to be a stimulus for mast cell degranulation. This paper studied the modulatory role of drugs that target protein kinase C (PKC), adenosine 3',5'-cyclic monophosphate (cAMP), tyrosine kinase (TyrK) and phosphatidylinositol 3-kinase (PI3K) on this effect. We used Go6976 (100 nM) and low concentrations of GF109203X (Gf) (50 nM) to inhibit calcium-dependent PKC isozymes. For calcium-independent isozymes, we used 500 nM Gf, and 10 microM rottlerin to specifically inhibit PKC delta, and chelerythrine as non-specific PKC inhibitor. Genistein (10 microM) and lavendustin A (1 microM) were used as unspecific TyrK inhibitors, and 10 nM wortmannin as a PI3K inhibitor. Chelerythrine and 50 nM Gf inhibit histamine release in the presence of external calcium. The inhibition caused by wortmannin was strictly internal calcium-dependent. cAMP-active drugs did not modify the response to NH4Cl. The effect of NH4Cl on histamine release was triggered by a transient elevation on cytosolic pH, which was simultaneous to an elevation on cytosolic calcium and followed by a probable Ca2+-H+ exchange after addition of external calcium. EGTA inhibit the response to suboptimal concentrations of NH4Cl, and BAPTA increased the effect of NH4Cl. There is a clear relationship between NH4Cl-mediated calcium release and histamine release, since those drugs that inhibit this release also inhibit NH4Cl-mediated histamine release; nevertheless, NH4Cl-mediated histamine release was possible in the absence of any calcium release, as shown with BAPTA. This data, in combination with the results with PKC inhibitors, suggest that calcium is not only unnecessary to trigger cell activation, but also that it may be a negative modulator of NH4Cl-mediated exocytosis.

Abstract
The effects of extracts from various oriental medicinal herbs on mast cell-mediated allergic reaction were investigated. Among them, Chrysanthemi sibirici herba ethanol extract exerted the potent inhibitory activity on antigen-induced degranulation in RBL-2H3 mast cells. Chrysanthemi sibirici herba dose-dependently inhibited DNP-BSA or compound 48/80-induced degranulation in RBL-2H3 mast cells, with IC(50) values of approximately 49 microg/ml and 76 microg/ml, respectively. This extract strongly suppressed compound 48/80-induced systemic anaphylaxis by 48.7% at a dose of 300 mg/kg in mice. Chrysanthemi sibirici herba also inhibited the expression of TNF-alpha and the activation of the MAP kinase, ERK1/2, which is critical for the production of inflammatory cytokines in mast cells, as indicated by the suppression of activating phosphorylation of ERK1/2. These results lead us to conclude that Chrysanthemi sibirici herba may be used clinically to treat various allergic diseases.

Abstract
Yunbutang (YB) is an Oriental herbal prescription, which has been successfully applied for the treatment of allergic disorders, mainly atopic dermatitis in clinical medicine. However, its effect in experimental models remains unknown. Here, we report inhibitory effects of YB on mast cell-dependent immediate-type allergic reactions. YB inhibited systemic allergic reaction induced by compound 48/80. YB dose-dependently inhibited the histamine release from the mast cells activated by compound 48/80. YB also showed an inhibitory effect of anti-dinitrophenyl IgE antibody-induced passive cutaneous anaphylaxis reaction by oral administration. Furthermore, YB inhibited tumor necrosis factor-alpha secretion from stimulated mast cells. These findings provide evidence that YB inhibits the mast cell-dependent allergic reactions.

Abstract
Boo Yong-Tang (BYT) is an Oriental herbal prescription, which has been clinically applied for treatment of allergic disorders. Here, we report inhibitory effects of BYT on experimental allergic reactions. BYT increased interferon-gamma secretion from MOLT-4 T cells. When BYT (0.01, 0.1, or 1 g/kg) was orally administered for 1 h in mice, compound 48/80-induced ear swelling was significantly reduced. BYT also inhibited the histamine release from the mast cells activated by compound 48/80. In addition, BYT showed an inhibitory effect of anti-dinitrophenyl IgE antibody-induced passive cutaneous anaphylaxis reaction. These findings provide evidence that BYT is a potential prescription for the treatment of allergic reaction through down-modulating of mast cell activation.

Abstract
We investigated the effect of disodium cromoglycate (DSCG) on mast cell-mediated immediate-type hypersensitivity. DSCG inhibited systemic allergic reaction induced by compound 48/80 dose-dependently. Passive cutaneous anaphylaxis was inhibited by 71.6% by oral administration of DSCG (1 g/kg). When DSCG was pretreated at concentration rang from 0.01-1000 g/kg, the serum histamine levels were reduced in a dose dependent manner. DSCG also significantly inhibited histamine release from rat peritoneal mast cell (RPMC) by compound 48/80. We confirmed that DSCG inhibited compound 48/80-induced degranulation of RPMC by alcian blue/nuclear fast red staining. In addition, DSCG showed a significant inhibitory effect on anti-dinitrophenyl IgE-mediated tumor necrosis factor-alpha production. These results indicate that DSCG inhibits mast cell-mediated immediate-type allergic reaction.

Abstract
Purple bamboo salt is a specially processed salt according to the traditional recipe using normal salt and bamboo etc. It has been used as a folk medicine for the purpose of prevention and treatment of various diseases in Korea. This report describes an inhibitory effect of purple bamboo salt on mast cell-mediated immediate-type allergic reactions. Purple bamboo salt (0.01-1 microg per site) significantly inhibited the ear swelling response induced by intradermal injection of compound 48/80 in mice. Purple bamboo salt (0.01-1 mg/ml) dose-dependently inhibited the histamine release from the rat peritoneal mast cells (RPMCs) by compound 48/80. Purple bamboo salt (0.01-1 g/kg) also dose-dependently inhibited the passive cutaneous anaphylaxis (PCA) by oral administration. Our results provide evidence that purple bamboo salt will be beneficial in the regulation of immediate-type of allergic reactions.

Abstract
This work aims at examining the effect of the concentrated methanol extract of Rubus croceacanthus Leveille (RCL) on mast cell-mediated anaphylactic-like reaction in a murine model. RCL inhibited compound 48/80-induced systemic anaphylactic-like reaction. When RCL 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 or anti-dinitrophenyl (DNP) immunoglobulin E (IgE) was reduced in a dose-dependent manner. RCL also inhibited passive cutaneous anaphylaxis activated by anti-DNP 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.

Abstract
The effect of aqueous extract of Xanthii fructus (XF) on mast cell-mediated allergic reaction has been investigated. XF inhibited compound 48/80-induced systemic anaphylaxis in mouse. This dose-dependently inhibited histamine release from rat peritoneal mast cells (RPMC) by compound 48/80. Additionally, XF inhibited local immunoglobulin E (IgE)-mediated passive cutaneous anaphylatic reaction. When XF (0.1mg/ml) was added, the secretion of tumor necrosis factor-alpha (TNF-alpha) from anti-dinitrophenyl (DNP) IgE antibody-stimulated mast cells was inhibited by 56%. Our studies provide evidence that XF may be beneficial in the treatment of various types allergic diseases.

Abstract
Yessotoxin (YTX) is a novel phycotoxin with an unknown mechanism of action that has been reported as cardiotoxic, when injected, but non-toxic if ingested orally. In this paper, we studied the effect of YTX on adenosine 3',5'-cyclic monophosphate (cAMP) pathway, since this pathway can be a cellular target to this toxin as happens in other diarrhetic toxins. We determined cAMP levels by enzymeimmunoassay and by using the cAMP dye recombinant fluorescein- and rhodamine-labeled protein kinase A, which increases their fluorescence when cAMP levels are increased. In the presence of YTX, and after a transient small increase, cAMP levels were decreased. This effect was Ca(2+) dependent since in a Ca(2+)-free medium YTX increased cAMP levels, but this event was reverted after addition of external calcium. YTX also reverted the increase of cAMP induced by the adenylyl cyclase activator forskolin. These variations in fluorescence units were confirmed when cAMP levels were measured by enzymeimmunoassay, YTX decreases cAMP from 52.81+/-3.66 to 44.53+/-4.5 fmol. Phosphodiesterase (PDE) IV inhibitors, rolipram or etazolate, did not modify the effect of YTX, however, when PDE IV was first inhibited no effect of YTX was observed. On the other hand, the PDE III inhibitor milrinone counteracted the effect of YTX, and a similar effect was observed with the unspecific PDE I inhibitor chlorpromazine. These results point to an effect of YTX on PDE activity. In the presence of YTX, the fluorescent PDE substrate Mant-cAMP, increased its rate of hydrolysis, the same as the PDE from bovine brain increased the hydrolysis of cAMP substrate. In addition, YTX increased interleukin-2 production, which indirectly confirms a decrease in cAMP. Although results show a very complex pattern of responses, due to the interactions and crosstalks between many systems, results suggest that YTX is a PDE activator in the presence of external Ca(2+).

Abstract
BACKGROUND Tongkyutang (TKT) is an Oriental herbal prescription, which has been successfully applied for the treatment of allergic disorders, mainly allergic-rhinitis in clinical medicine. However, its effect in experimental models remains unknown. METHODS In a mouse model, the role of TKT was examined in mast cell-dependent allergic reactions and secretion of inflammatory cytokines. RESULTS TKT concentration-dependently inhibited the ear-swelling response induced by intradermal injection of compound 48/80. TKT inhibited the compound 48/80-induced degranulation from mast cells in ear tissue. TKT dose-dependently inhibited the histamine release from the rat peritoneal mast cells by compound 48/80. TKT also showed inhibition of anti-dinitrophenyl IgE antibody-induced passive cutaneous anaphylaxis reaction by oral administration. Furthermore, TKT inhibited both IL-1beta and TNF-alpha secretion induced by PMA and A23187, respectively. CONCLUSIONS Our findings provide evidence that TKT inhibits the mast cell-dependent allergic reactions and inflammatory cytokines secretion.

Abstract
It has recently been reported that phycocyanin, a biliprotein found in the blue-green microalgae Spirulina, exerts anti-inflammatory effects in some animal models of inflammation. Taking into account these findings, we decided to elucidate whether phycocyanin might exert also inhibitory effects in the induced allergic inflammatory response and on histamine release from isolated rat mast cells. In in vivo experiments, phycocyanin (100, 200 and 300mg/kg post-orally (p.o.)) was administered 1 h before the challenge with 1 microg of ovalbumin (OA) in the ear of mice previously sensitized with OA. One hour later, myeloperoxidase activity and ear edema were assessed. Phycocyanin significantly reduced both parameters. In separate experiments, phycocyanin (100 and 200 mg/kg p.o.) also reduced the blue spot area induced by intradermal injections of histamine, and the histamine releaser compound 48/80 in rat skin. In concordance with the former results, phycocyanin also significantly reduced histamine release induced by compound 48/80 from isolated peritoneal rat mast cells. The inhibitory effects of phycocyanin were dose dependent. Taken together, our results suggest that inhibition of allergic inflammatory response by phycocyanin is mediated, at least in part, by inhibition of histamine release from mast cells.

Abstract
Dendroaspis natriuretic peptide (DNP), recently isolated from the venom of the green Mamba snake Dendroaspis angusticeps, is a 38 amino acid peptide containing a 17 amino acid disulfide ring structure similar to that of the natriuretic peptide family. The natriuretic peptide family is known to induce histamine release from human and rat mast cells, but there are no published data concerning the effects of DNP on histamine release from mast cells. The purpose of this study is to investigate whether DNP induces the histamine release from rat peritoneal mast cells (RMPCs) and to determine the mechanism of DNP-induced histamine release from RPMCs. After treatment of RPMC with DNP, mast cell degranulation was observed, and calcium uptake and histamine release were measured. DNP released the histamine, induced the mast cell degranulation, and increased the calcium uptake of RPMCs, in a dose-dependent manner. The results indicate that DNP can increase Ca-uptake and induce histamine release.

Abstract
This report describes an inhibitory effect of Gahmi-Shini-San (GSS) on mast cell-mediated immediate-type allergic reactions. GSS is an Oriental herbal medication, which has been successfully used in Korea for the treatment of allergic disorders, mainly skin anaphylactic diseases. GSS inhibited the ear swelling response induced by intradermal injection of compound 48/80 in a mouse model on a concentration-dependent basis. The mast cells in mouse ear tissue were stained by alcian blue/nuclear fast red. GSS significantly inhibited the compound 48/80-induced degranulation from mast cells in ear tissue. GSS dose-dependently inhibited the histamine release from the rat peritoneal mast cells by compound 48/80. We also studied the effect of GSS on mast cell-dependent passive cutaneous anaphylaxis activated by dinitrophenyl IgE antibody. GSS showed inhibition of passive cutaneous anaphylaxis following oral administration. These results indicated that GSS has inhibitory effect on mast cell-dependent immediate type cutaneous reactions.

Abstract
The digitalic glicoside ouabain induces potentiation of rat mast cell histamine release in response to several stimuli, which is mediated by Na+/Ca2+ exchanger. In this work, we studied the effect of ouabain on cytosolic calcium, intracellular pH and histamine release with Ca2+ ionophore A23187 in conditions designed to maximize ouabain-induced potentiation of rat mast cells response. The effect of protein kinase C (PKC), cAMP and phosphatase inhibition was also tested. Ouabain induced an enhancement in histamine release, cytosolic calcium and intracellular pH. The adenylate cyclase activator forskolin reduced the effect of ouabain on histamine release and intracellular pH, but enhanced the effect on cytosolic calcium. PKC activator PMA enhanced the effect of ouabain on histamine release and cytosolic calcium, without affecting intracellular pH. A PKC inhibitor, GF-109203X, reduced ouabain-induced enhancement of histamine release and intracellular pH, but increased the enhancement on cytosolic calcium. Finally, inhibition of protein phosphatases 1 and 2A with okadaic acid, increased the effect of ouabain on histamine release and intracellular pH, but reduced cytosolic calcium in presence of ouabain. This result suggest that ouabain-induced potentiation of rat mast cell histamine release with A23187 is modulated by kinases, and this modulation may be carried out by changes in intracellular alkalinization. However, the mechanism underlying cellular alkalinization remains to be elucidated.
