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 the 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 (WBB6F1-+/+) mice but not in the congenic mast cell-deficient WBB6F1-W/Wv 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.

UI	MeSH Term	Description	Entries
D006969	Hypersensitivity, Immediate	Hypersensitivity reactions which occur within minutes of exposure to challenging antigen due to the release of histamine which follows the antigen-antibody reaction and causes smooth muscle contraction and increased vascular permeability.

D007073	Immunoglobulin E	An immunoglobulin associated with MAST CELLS. Overexpression has been associated with allergic hypersensitivity (HYPERSENSITIVITY, IMMEDIATE).	IgE
D008407	Mast Cells	Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR.	Basophils, Tissue,Basophil, Tissue,Cell, Mast,Cells, Mast,Mast Cell,Tissue Basophil,Tissue Basophils
D010323	Passive Cutaneous Anaphylaxis	An evanescent cutaneous reaction occurring when antibody is injected into a local area on the skin and antigen is subsequently injected intravenously along with a dye. The dye makes the rapidly occurring capillary dilatation and increased vascular permeability readily visible by leakage into the reaction site. PCA is a sensitive reaction for detecting very small quantities of antibodies and is also a method for studying the mechanisms of immediate hypersensitivity.

D004487	Edema	Abnormal fluid accumulation in TISSUES or body cavities. Most cases of edema are present under the SKIN in SUBCUTANEOUS TISSUE.	Dropsy,Hydrops,Anasarca
D006636	Histamine Release	The secretion of histamine from mast cell and basophil granules by exocytosis. This can be initiated by a number of factors, all of which involve binding of IgE, cross-linked by antigen, to the mast cell or basophil's Fc receptors. Once released, histamine binds to a number of different target cell receptors and exerts a wide variety of effects.	Histamine Liberation,Histamine Liberations,Histamine Releases
