Objective: Experimental studies were done to research the effects of Jahap-san(zige-san) on the allergic reaction Methods: For measuring the response about the antiallergic effect we investigated cytokines m-RNA expression of murine splenic B cell, production in anti-CD40 mAb-stimulated murine splenic B cells and the histamine release in IC-2 cells by anti-CD40 mAb-stimulated murine splenic B cells. Results: The extract of Jahap-san(zige-san) revealed significant decrease effect on cytokines m-RNA expression of murine splenic B cell, production in anti-CD40 mAb-stimulated murine splenic B cells and the histamine release in IC-2 cells by anti-CD40 mAb-stimulated murine splenic B cells. Conculusion : The extract of Jahap-san(zige-san) revealed significant effect on the antiallergy.

To evaluate the antithrombotic and antiallergic properties of rhaponticin extracted from Rhei Rhizoma, the in vitro and ex vivo inhibitory activities of rhaponticin and its metabolite, rhapontigenin, were measured. These compounds inhibited in vitro ADP- and collagen-induced platelet aggregation. Rhapontigenin was more potent, with $IC_{50}$ values of 4 and $70{\;}{\mu}g/ml$, respectively. In ex vivo ADP- and collagen-induced rat platelet aggregation, these compounds also exhibited a potent inhibitory effect. The antiplatelet aggregation effects of rhaponticin and rhapontigenin were more potent than those of aspirin. Rhapontigenin showed significant protection from death due to pulmonary thrombosis in mice. Rhapontigenin also showed the strongest inhibitory activity against $\beta-hexosaminidase$ release induced by DNP-BSA. These compounds inhibited PCA reaction in mice. Rhapontigenin intraperitoneally administered showed the strongest inhibitory activity and significantly inhibited PCA at doses of 25 and 50 mg/kg, with inhibitory activities of 48 and 85%, respectively. The inhibitory activity of orally administered rhaponticin was stronger than that of intraperitoneally administered rhaponticin. These results suggest that rhaponticin, in the rhizome of Rhei Rhizoma, is a prodrug that has extensive antiallergic and antithrombotic properties.

Antiallergic activity of the aqueous extract of Menthae herba (MHAE) was investigated in mice and rats. MHAE inhibited systemic anaphylaxis induced by compound 48/80 in mice. Especially, MHAE inhibited compound 48/80 induced systemic anaphylaxis 100% with a dose of 500 mg/kg body weight. MHAE significantly inhibited serum histamine levels induced by compound 48/80. MHAE inhibited histamine release from the rat peritoneal mast cells activated by compound 48/80 or anti-DNP IgE. Our studies provide evidence that MHAE will be beneficial in the treatment of anaphylaxis.

To evaluate the antiallergic effect of the dried root of Astragalus membranaceus Bunge (AM) (Leguminosae), which inhibited the mouse passive cutaneous anaphylaxis (PCA) reaction in a preliminary experiment, its main constituents, astragalosides I and IV, were isolated and their antiallergic effects were investigated. Astragalosides I and IV inhibited the PCA reaction induced by the IgE-antigen complex, and the scratching behaviors induced by compound 48/80. These constituents reduced the protein expressions of $TNF-{\alpha}$ and IL-4 in IgE-induced RBL-2H3 cells. These findings suggest that astragalosides I and IV as well as AM can improve IgE-induced anaphylaxis and scratching behaviors.

Ginseng (the root of Panax ginseng C.A $M_{EYER}$, family Araliaceae) is frequently used as a crude substance in Asian countries as a traditional medicine. The major components of ginseng are ginsenosides, which have been reported to show various biological activities including antiinflammatory activity and antitumor effect. In addition, Sugiyama et al. reported that ginsenoside Rg3 suppresses histamine release from mast cells due to stimulation with compound 48/80 in vitro. However, the antiallergic effects of ginsenoside Rh2, which is metabolized by human intestinal bacteria to ginsenoside Rg3, have not been studied. (omitted)

When ginsenoside Rg5, a main component isolated from red ginseng, was incubated with three human fecal microflora for 24 h, all specimens showed hydrolyzing activity: all specimens produced ginsenoside Rh3 as a main metabolite, but a minor metabolite $3{\beta},12{\beta}$-dihydroxydammar-21(22),24-diene (DD) was observed in two specimens. To evaluate the antiallergic effect of ginsenoside Rg5 and its metabolites, the inhibitory effect of ginsenoside Rg5 and its metabolite ginsenoside Rh3 against RBL-2H3 cell degranulation, mouse passive cutaneous anaphylaxis (PCA) reaction induced by the IgE-antigen complex, and mouse ear skin dermatitis induced by 12-O-tetradecanoilphorbol-13-acetate (TPA) were measured. Ginsenosides Rg5 and Rh3 potently inhibited degranulation of RBL-2H3 cells. These ginsenosides also inhibited mRNA expression of proinflammatory cytokines IL-6 and $TNF-{\alpha}$ in RBL-2H3 cells stimulated by IgE-antigen. Orally and intraperitoneally administered ginsenoside Rg3 and orally administered ginsenoside Rg5 to mice potently inhibited the PCA reaction induced by IgE-antigen complex. However, intraperitoneally administered ginsenoside Rg5 nearly did not inhibit the PCA reaction. These ginsenosides not only suppressed the swelling of mouse ears induced by TPA, but also inhibited mRNA expression of cyclooxygenase-2, $TNF-{\alpha}$, and IL-4 and activation of transcription factor NF-kB. These inhibitions of ginsenoside Rh3 were more potent than those of ginsenoside Rg5. These findings suggest that ginsenoside Rg5 may be metabolized in vivo to ginsenoside Rh3 by human intestinal microflora, and ginsenoside Rh3 may improve antiallergic diseases, such as rhinitis and dermatitis.

The unripe fruit of Poncirus trifoliata Raf has been used for the treatment of allergic disease. Recently it was reported that the fruit inhibits passive cutaneous anaphylaxis and histamine release at mast cell. Type I immediate hypersensitivity of anaphylactic type is caused by released mediate chemical at mast cell. Histamine is also known as one of potent mediate chemical. Also release of mediate chemical is affected by specific stimulation of IgE combined with mast cell. Activation of mast cell is known to be stimulated by compound 48/80 and inhibited by increase of cAMP. In this experiment, the effect of water extract of Poncirus trifoliata Raf fruit (PT) on a histamine release, cAMP concentration and IgE production was measured. Compound 48/80 was administrated to the mouse peritoneal cell which was pretreated with PT. PT dosedependently inhibited histamine release at peritoneal mast cell and the serum level of histamine induced by compound 48/80. PT also instantly increased cAMP level of peritoneal mast cell right after it was added and the level gradually decreased. Production of IgE induced by antigens at mouse peritoneal cell was inhibited by PT. The IgE synthesis is induced by IL-4 and it is known that lipopolysaccharide(LPS) plus IL-4 cause an increase in IgE secretion by murine B cells. The effects of PT inhibited the production of IgE activated by LPS plus IL-4 at human U266B1 cells. These results indicate that PT has antiallergic activity by Inhibition of IgE production from B cells and histamine release by increase of cAMP.
