Effects of Panax ginseng on allergic reactions were studied uslng various in vivo and in vitro experimental models such as 48-hr passive cutaneous anaphylaxis, mediators-induced skin reactions, histamine release from rat peritoneal mast cells, hexosaminidase release from RBL-2H3 cells, and lipoxygenase assay . In all of anti-allergic experiments we conducted, ginseng components (50% ethanol extract or ginseng total saponin or ginsenosides) extracted from Korean red ginseng, did not show significant anti-allergic actions. In 48-hr passive cutaneous anaphylaxis and mediators-induced skin reactions, 50% ethanol extract did not suppress hypersensitivity reactions. Total saponin, 50% ethanol extract, and 8 major ginsenosides did not show inhibitory effects on lipoxygeanse activity. Ginseng total saponin did not inhibit histamine release from rat peritoneal mast cells. All of the ginseng components mentioned above were also tested on RBL-2H3 cells, but none of them inhibited hexosaminidase release from this cell line. These results suggest that Panax ginseng does not have effects on allergic reactions at the level of 50% ethanol extract or total saponin used. All of 8 major saponin components tested ($Rb_1$, $Rb_2$, Rc, Rd, Re, Rf, $Rg_1$, $Rg_2$), did not inhibit lipoxygenase activity and degranulation events.

The aqueous extract of Siegesbeckia pubescens (SPAE) inhibited compound 48/80-induced systemic anaphylaxis 100% with the dose of 1.0, 0.5 mg/g body weight (BW) at 1 h before or 5 min, 10 min after intraperitoneal injection of compound 48/80. The passive cutaneous anaphylaxis (PCA) reaction also inhibited to 78.5% by oral administration of SPAE(1.0 mg/g BW). When SPAE pretreated on mice at concentrations ranging from 0.0001 to 1.0 mg/g BW, the serum histamine levels were reduced in a dose-dependent manner. Moreover, SPAE ($100-800{\mu}g/ml) dose-dependently inhibited the histamine release from peritoneal mast cells (RPMC) by compound 48/80 $(5{\mu}g/ml)$. Analysis by microscopic appearance observation revealed that SPAE $(500{\mu}g/ml) stabilized the RPMC membrane. Therefore, these findings indicate that SPAE inhibits anaphylactic reactions through stabilization of mast cell membrane.

Objective We investigated the effect of Saururus chinensis (Lour.) Baill. aquacupuncture (SCB) on anaphylaxis in mice. Methods : We conformed compound 48/80-induced mesenteric mast cell degranulation, active systemic anaphylatic shock and histamine release. Also observed acetic acid-induced vascular permeability and anti-dinitrophenyl (DNP) IgE-mediated passive cutaneous anaphylaxis. Results : SCB inhibited mesenteric mast cell degranulation and active systemic anaphylatic shock induced by compound 48/80 dose-dependently. When SCB was pretreated by intra-peritoneal injection, the serum histamine levels were reduced. SCB also significantly inhibited acetic acid-induced vascular permeability. In addition, SCB showed a significant inhibitory effect on anti-dinitrophenyl (DNP) IgE-mediated passive cutaneous anaphylaxis. Conclusion : These results indicated that SCB inhibits anaphylatic reaction.

Anti-allergic and anti-inflammatory actions of the water extract from Cimicifuga heracleifolia were evaluated in mice and rats. Several criteria were employed to assess the anti-allergic and anti-inflammatory actions of Cimicifuga heracleifolia, such as hyaluronidase activity, mediators-induced vascular permeability changes, 48 hour homologous passive cutaneous anaphylaxis (PCA) histamine release from mast cells, and the carrageenan-induced rat paw edema. To further characterize the active components, the water extract was either extracted with organic solvent or fractionated according to molecular weight, and each fraction was tested for some of anti-allergic parameters. Hyaluronidase activities, both in activating and in activated states, were significantly inhibited by the water extract of Cimicifuga heracleifolia and by some of its subfractions, molecular weight less than 1,000. The water extracts (50~400 mg/kg) significantly inhibited 48 hr homologous PCA and vascular permeability changes induced by chemical mediators (histamine, serotonin, and leukotriene $C_4$) in mice. In the case of histamine-induced vascular permeability changes, more extensive studies were conducted; water extract was either fractionated according to molecular weight or extracted with butanol. Anti-histamine actions were observed only from the water layer, and these active components were of the molecular weight less than 1,000. These anti-allergic actions were observed mainly from mice than from rats. On the other hand, anti-inflammatory actions of the water extract from Cimicifuga heracleifolia were significant in rats.

The effect of aqueous extract of Stachys riederi var. japonica Miq. (Labiatae) (SRAE) on the immediate-type allergic reactions was investigated. SRAE was found to exhibit a inhibitory activity on the compound 48/80-induced systemic anaphylaxis in mice. SRAE inhibited the plasma histamine release induced by compound 48/80 in mice. In addition, SRAE also inhibited the passive cutaneous anaphylaxis reaction induced by IgE/anti-IgE in mice. The effect of SRAE on the histamine release from rat peritoneal mast cells (RPMC) was studied. SRAE inhibited the histamine release induced by compound 48/80 in RPMC. To clarify the mechanism of these inhibiting reactions, we investigated the effects of SRAE on cyclic AMP (cAMP). The level of cAMP in human leukemia cell line, HMC-1, when SRAE (1 mg/ml) was added, significantly increased compared with that of basal cells. These results indicate that SRAE may be beneficial in the treatment of immediate-type allergic reaction.

We investigated the effect of Sungmagalkun-tang (SGT) on the allergy. We conformed compound 48/80-induced active systemic anaphylatic shock, anti-dinitrophenyl IgE-mediated passive cutaneous anaphylaxis and ovalbumin-induced anaphylatic shock. Also observed IL-4 and GM-CSF mRNA expression in ovalbumin-induced allergic lung tissue and RBL-2H3. Histamine release is measured in RBL-2H3. SGT inhibited active systemic anaphylatic shock, passive cutaneous anaphylaxis and ovalbumin-induced anaphylatic shock by oral administration. We observed that SGT was concentration-dependently reduced IL-4 and GM-CSF mRNA expression in ovalbumin-induced allergic lung tissue and RBL-2H3 by SGT. In addition, SGT reduced histamine release in RBL-2H3. These results indicate that SGT has anti-histamic effect and controls IL-4 and GM-CSF mRNA expression on allergy.

The discovery of drugs for the treatment of mast cell-mediated allergic disease is a very important subject in human health. The Amomum xanthiodes (Zingiberaceae) has been used for centuries 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 Amomum xanthiodes (EAX) on the mast cell-mediated allergic reaction and studied its possible mechanisms of action. EAX inhibited compound 48/80-induced systemic anaphylaxis and serum his­tamine release in mice. EAX decreased the passive cutaneous anaphylaxis reaction activated by anti-dinitrophenyl (DNP) IgE antibody. EAX dose-dependently reduced histamine release from rat peritoneal mast cells activated by compound 48/80 or anti-DNP IgE. EAX increased cAMP and decreased compound 48/80-induced intracellular $Ca^{2+}$ levels. Our findings provide evidence that EAX inhibits mast cell-derived allergic reactions, and also demonstrate the involvement of cAMP and intracellular $Ca^{2+}$ in these effects.

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

The flowers of Lonicera japonica Thunb. (Caprifoliaceae) have been used as a traditional effective drug in treating bacillary dysentery, purulence. However, the exact role of Lonicera japonica in allergic reaction has not been clarified yet. Immediate hypersensitivity, popularly known as allergy, is a major clinical problem in humans. It has been found that the histamine release from mast cells is an essential step in the pathological process of immediate hypersensitivity. In this study, the effect of aqueous extract of Lonicera japonica (AELJ) on allergic reaction was investigated. AELJ inhibited the compound 48／80-induced anaphylactic reactions and antigen-induced passive cutaneous anaphylaxis (PCA). AELJ in vitro exhibited a dose-dependent inhibition of degranulation in RPMC stimulated by compound 48／80. AELJ also suppressed the morphological changes and the increase of intracellular free calcium level induced by compound 48／80. These results suggest that inhibitory effect of AELJ on allergic reaction may be mediated through the decrease of intracellular free calcium levels, and AELJ importantly contributes to the treatment of anaphylaxis and may be useful for other allergic disease.
