  • The mast cell plays a pivotal role in initiating allergic response by secreting intracytoplasmic granular mediators such as histamine. Magnoliae flos has been used for treatment of allergic disease in Korea. However, its effect in experimental models remains unknown. The present report describes an inhibitory effect of Magnoliae flos on mast cell-mediated immediate-type allergic reactions. Topical application of compound 48/80 can induce an ear swelling response in normal($WBB6F_1-+/+$) mice but not in the congenic mast cell-deficient $WBB6F_1-W/W^v$ mice. Magnoliae flos inhibited concentration-dependently mast cell-dependent ear swelling response induced by compound 48/80 by topical application. Magnoliae flos inhibited concentration-dependently passive cutaneous anaphylaxis induced by anti-dinitrophenyl (DNP) IgE in rats by topical application. Magnoliae flos also inhibited concentration-dependently the histamine release from the rat peritoneal mast cells by compound 48/80 or anti-DNP IgE. Moreover, Magnoliae flos had a significant inhibitory effect on compound 48/80-induced systemic anaphylactic reaction. These results indicate that Magnoliae flos inhibits immediate-type allergic reactions by inhibition of mast cell degranulation in vivo and in vitro.

  • Objectives : Allergy is an immune dysfunction caused by degranulation from mast cells in the early phase of allergic disease including allergic rhinitis (AR). The purpose of this study was to investigate the effects of Osterici Radix, roots of Ostericum koreanum Maximowicz in human mast cells and experimental allergic animal models. Methods : The anti-allergic effect of Osterici Radix water extract (NK-W) was investigated in human mast cell line, HMC-1 cells, and compound 48/80-induced systemic anaphylactic response in rats and ovalbumin (OVA)-induced AR in mice. Animals were orally administrated with NK-W (10 and 50 mg/kg) or anti-histamine drug, dosodium cromoglycate (50 mg/kg), and then intraperitoneally injected with compound 48/80 (8 mg/kg) or sensitized with 0.1% OVA into nasal. Animals were observed plasma histamine and histological changes of nasal mucosa. Also, mast cell degranulation and histamine production were determined in compound 48/80-stimulated HMC-1 cells. Results : NK-W inhibited compound 48/80-induced degranulation of mast cells and histamine releasing in HMC-1 cells. NK-W decreased mortality and serum histamine releasing in compound 48/80-induced anaphylatic rats in a dose-dependently manner. NK-W also inhibited serum histamine levels in OVA-induced AR mice and improved abnormal histological changes such as expansion of grandular cells and hypertrophy of epithelium in the nasal mucosa. These results indicate that Osterici Radix water extract suppress allergic response through downregulation of mast cell activation. Conclusions : This study suggests that a therapeutic potential of Osterici Radix as a source of anti-allergic agents for use in a number of allergic diseases.

  • This experimental research has been done to study the effects of Gmibojungikgi-tang(GBJIKT) on the anti-allergic reaction. We found the several important results from the research which has been performed by two experiments toward immediately type and delayed type in order to study the effects of GBJIKT on hypersensitivity response to mice. The results obtained from our research are as following: The survival rate of one group to which we injected only the compound 48/80 is almost 0% according to its density and timing test. In the other hand, the survival rates of the other group to which we injected both of the compound 48/80 and GBJIKT are 10%, 10%, 20%, 30%, 20%, and 40% according to 0.025, 0.05, 0.1, 0.25 0.5 and 1(mg/g) of compound 48/80. Time dependency test also shows the 0% survival rates in 5 and 10 minutes. GBJIKT revealed the significantly inhibitory effect on Compound 48/80 induced Mast cell degranulation. GBJIKT showed the significantly inhibitory effect in the delayed type hypersensitivity response to picry1 chloride GBJIKT showed the significantly inhibitory effect in the delayed type hypersensitivity response to sheep red blood cell. Our research provides the important evidence that GBJIKT is benificial to the prevention and treatment of allergy related diseases.

  • Ginsenosides are responsible for the pharmacological and biological activities of ginseng. In this study, ginsenoside Rh1 and compound K were isolated and purified from fermented ginseng substrate and their anti-allergic effects were assessed in compound 48/80-induced anaphylactic shock model. The fermented ginseng substrate was extracted by methanol and ginsenoside Rh1 and compound K were efficiently purified by preparative high performance liquid chromatography (prep HPLC). Their quality and quantity were analyzed by liquid chromatography-mass spectrometer (LC-MS) and HPLC. Ginsenoside Rh1 showed better anti-allergic effects than compound K in compound 48/80-induced anaphylactic shock model. This study suggested that fermented ginseng extracts with enriched Rh1 may be utilized as a potential biomaterial of functional food for the alleviation of allergic symptoms.

  • The effect of aqueous extract of Lycopus lucidus Turcz. (Labiatae)(LLAE) on mast cell-mediated immediate-type allergic reactions was investigated. LLAE (0.01 to 1 mg/g) dose-dependently inhibited systemic anaphylaxis induced by compound 48/80. LLAE (0.001 to 1 mg/g) also dose-dependently inhibited local anaphylaxis activated by anti-dinitrophenyl (DNP) IgE. When LLAE was pretreated at the same concentration with systemic anaphylaxis, serum histamine levels were reduced in a dose-dependent manner. LLAE (0.001 to 1 mg/mι) dose-dependently inhibited histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. The level of cAMP in human mast cell line (HMC-1) cells, when LLAE (1 mg/mι) was added, significantly was increased, compared with that of normal control. These results provide evidences that LLAE may be beneficial in the treatment of allergic diseases.

  • The effects of extracts from various Oriental medicinal herbs on mast-cell-mediated allergic reactions were investigated in this study. Out of these extracts, the medicinal herb Atractylodis rhizoma alba exhibited the most potent activity in the cells, with $IC_50$ values of $20.5\;{\mu}g/ml$, by DNP-BSA and $33.04\;{\mu}g/ml$, by compound 48/80. Similar to the in vitro activity, Atractylodis rhizoma alba inhibited compound-48/80-induced systemic anaphylaxis by 31.3% at 300 mg/kg in mice. It also suppressed the secretion of $TNF-{\alpha}$, a major pro-inflammatory cytokine in the cells. These results may suggest that Atractylodis rhizoma alba shows anti-allergic activity in compound 48/80-induced anaphylactic mice through the inhibition of mast cells.

  • The effect of aqueous extract of Isodon japonicus Hara (Labiatae) (IJAE) on mast cell-mediated immediate-type allergic reactions was investigated. IJAE inhibited compound 48/80-induced systemic anaphylaxis and immunoglobulin E (IgE)-mediated local anaphylaxis. When IJAE was pretreated at the same concentration with systemic anaphylaxis, serum histamine levels were reduced in a dose-dependent manner. IJAE dose-dependently inhibited histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. The level of cAMP in human mast cell line (HMC-1) cells, when IJAE was added, significantly was increased, compared with that of normal control. These results indicate that IJAE will beneficial in the treatment of immediate-type allergic reaction.

  • Mortality test has been utilized as a basic method for systemic anaphylactic reaction. Compound 48/80 has been used as a direct and convenient reagent to study the mechanism of anaphylacic reaction. The aqueous extracts of 102 medicinal plants were screened for mortality test using compound 48/80. Sixteen out of the 102 medicinal plants exhibited more than 50% of inhibition on mortality test by their total aqueous extracts with 0.1 mg/g as a final concentration.

  • The effect of aqueous extract of Magnoliae Cortex (Magnoliaceae) (MCAE) on the immediate-type allergic reaction was investigated. MCAE inhibited compound 48/80 induced systemic anaphylactic reaction in rats. MCAE (0.1 and 1 g/kg) also significantly inhibited local immunoglobulin E (lgE)-mediated passive cutaneous anaphylactic (PCA) reaction. MCAE (0.001 to 1 mg/ml) dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-dinitrophenyl (DNP) 1gE. Moreover, MCAE (0.01 to 1 mg/ml) had a significant inhibitory effect on anti-DNP IgE-mediated tumor necrosis $factor-{\alpha}$ $(TNF-{\alpha})$ production. These results indicate that MCAE inhibits immediate-type allergic reaction in vivo and in vitro.
