During the course of searching for anti-allergic substances from unexplored plant sources, an inhibitor of leukotriene $D_4$-induced tracheal contraction was isolated from Euphoribia helioscopia. This isolated polyphenol compound, known as helioscopinin-A, showed a certain inhibitory activity on capillary permeability in passive cutaneous anaphylaxis responses of rats and also on antigen-induced bronchial constriction in an experimental asthma model of guinea pigs. The compound at a high concentration weakly inhibited histamine release from isolated mast cells of rats. It is suggested that this compound is an anti-allergic and anti-asthmatic which exerts its activity through antagonism on leukotrene $D_4$-induced responses. A partial inhibition of allergic mediator relase may also bee involved.

Gunjung-tang(GJT) has been reported at Shanghanlun(傷寒論), which has been used for the treatment of general weakness, digestive organ disease and the treatment of allergic disorders in clinical medicine. However, its effect in experimental models remains unknown. In a rat and mouse model, the role of GJT was examined in mast cell-dependent allergic reactions and secretion of inflammatory cytokines. GJT inhibited anti-dinitrophenyl IgE antibody-induced passive cutaneous anaphylaxis reaction by Intraperitoneal pretreatment. GJT inhibited both IL-1β and TNF-α secretion on egg albumin induced allergic tissues and compound 48/80 induced thymus. Furthermore, GJT enhanced Band T lymphocytes proliferation. Our findings provide evidence that GJT inhibits the IgE-dependent allergic reactions and inflammatory cytokines secretion, and enhanced immune response.

Rumex crispus is known to have anticancer, antioxidant, antibacterial, and bone loss inhibitory activities. Mast cells are critical immune cells that induce a type 1 IgE-mediated allergic reaction. However, there are no reports of inhibitory effects of Rumex crispus on mast cells and allergic reactions. In this study, we performed some experiments to investigate whether Rumex crispus ethanol extract(RCE) has any inhibitory effect on antigen-induced type I allergic response in vitro and in vivo. RCE inhibited degranulation of IgE-mediated mast cells(IC₅₀, ~57 ㎍/ml) and cytokine production such as TNF-α and IL-4 in a dose-dependent manner. In vivo, RCE significantly inhibited passive cutaneous anaphylaxis(PCA)(ED₅₀, ~198 mg/kg) in mice. Furthermore, RCE inhibited degranulation of MCs in ear tissue of mice with PCA. Mechanism studies showed that RCE inhibited the activation of Syk and Syk-dependent pathway such as LAT, PLC-γ, Akt, and MAP Kinase. Our results demonstrate for the first time that RCE inhibits type I hypersensitive response by suppressing the activity of Syk in mast cells, thereby reducing degranulation and cytokine production. Taken together, RCE could be used as a novel therapeutic material to suppress allergic diseases.

Objective : Anal Therapy is another way of taking medicine and applies to each field of clinical treatment extensively. Sinpo-tang(SPT) has been used for the treatment of a allergic rhinitis. In this study, the auther investigated the anti anaphylactic action of Sinpo-tang by anal therapy was investigated on cutaneous allergic reaction models. Methods : Results : 1. Sinpo-tang (0,001-0.1 g/kg) dose-dependently inhibited the compound 48/80-induced ear swelling response in mice. Inhibitory effect of Sinpo-tang was significant (P < 0.05) at the doses of 0.01, 0.1 g/kg. 2. Sinpo-tang (0.001-0.1 g/kg) inhibited the cutaneous allergic reaction activated by anti-dinitrophenyl IgE in rats. Of special note, Sinpo-tang (0.1 g/kg) inhibited the cutaneous allergic reaction by $68\%$. 3. This inhibitory effect of Sinpo-tang was confirmed by observation of alcian blue/nuclear fast red stained-mast cells in the cutaneous tissue. 4. Sinpo-tang (0.01-1 g/L) dose-dependently inhibited the compound 48/80-induced histamine release from the peritoneal mast cells. Conclusions :These results indicate that anal therapy of Sinpo-tang may be beneficial in the treatment of mast cell-mediated anaphylaxis by inhibition of histamine release from mast cells in vivo and in vitro.

Buckwheat is known as a health food but is one of the major food allergens triggering potentially fatal anaphylaxis in Asia, especially in Japan and Korea. This study was conducted to investigate the characteristic of enzymatic resistance of buckwheat protein and allergenic potential. Enzymatic resistance of buckwheat protein was performed with in vitro digestibility test in simulated gastric fluid (SGF), pH 1.2, using pepsin and simulated intestinal fluid (SIF) using chymotrypsin. Reactivity of buckwheat proteins to human IgE was performed using six allergic patients sensitized to buckwheat. Buckwheat's IgE levels were measured using the Phadia UniCAP-system. Buckwheat protein, 16 kDa, still remained after 30 min treatment of pepsin on SDS-PAGE. Even though 16 kDa almost disappeared after 60 min treatment, two out of the six buckwheat patients' sera showed reactivity to hydrolysate after 60 min treatment, indicating that allergenicity still remained. In simulated intestinal fluid (SIF) using chymotrypsin, buckwheat protein, 24 kDa, showed resistance to hydrolysis with chymotrypsin on SDS-PAGE, and still had allergenicity based on the result of ELISA. Our results suggest that buckwheat proteins have strong resistance to enzyme degradation. This may be attributed in part to the allergenic potential of buckwheat. Further study should be continued regarding buckwheat allergy.

Objective : Mast cells are a potent source of mediators that regulate inflammatory response in allergies and asthma. The author studied the effect of Bojungikgitanggamibang(BITB) on mast cell-mediated anaphylactic reaction. Method : When BITB 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 was reduced in a dose-dependent manner. Result : BITB dose-dependently inhibited compound 48/80-induced systemic anaphylactic shock. BITB also inhibited passive cutaneous anaphylaxis activated by anti-dinitrophenyl IgE. In addition, BITB inhibited phorbol 12-myristate 13-acetate and A23187-induced interleukin-6 secretion from human mast cell line HMC-1 cells. Conclusion : These results indicate that BITB may be actively anti-allergic.

Although wheat is a common staple food in the world, some people suffer from a variety of wheat allergies. For example, wheat-dependent exercise-induced anaphylaxis is induced in the gastrointestinal tract by wheat proteins. Relatively high molecular weight proteins that are salt-insoluble induce many wheat allergies. In the present study, we investigated the induction of an allergy response using crude wheat proteins, which are relatively low molecular weight, salt-soluble proteins. The crude antigen used in this study was extracted using phosphate buffered saline. When the antigen extracts from various wheat cultivars were orally administered, differentiable degrees of allergy responses were observed as measured by serum IgE and histamine secretion compared to the control. Serum IgE levels increased following administration of three of the wheat extracts. This evidence suggests that a combination of salt-soluble wheat proteins could be antigens for the induction of various allergy responses.

This study was undertaken to evaluate safety and antitumor activity of Nexia, a processed extract of Rhus verniciflua STOKES by heating according to Korean patent 0504160 through toxicology, cancer research and clinical application. Nexia did not exhibit any toxicological symptoms through 13 week continuous treatment, dosage accumulation study and anaphylaxis response. The lifespan of four patients with acute lymphocytic leukemia under complete remission were 110, 83, 97, and 86 months after treatment of Nexia, respectively. These data suggest that Nexia, a processed extract by removing allergen from Rhus verniciflua STOKES, may have safety and antitumor activity and also still need continuous study on its mechanism and clinical trial.
