anaphylaxis | anaphylaxis \anaphylaxis\ n. 1. [Gr. 'ana` back, way from + fy`laxis security, protection.] 1. (Med.) hypersensitivity (to a protein or drug) resulting from prior contact with a substance. [WordNet 1.5] 2. (Med.) an immediate but transient allergic reaction to an antigenic substance to which a person has become hypersensitized; it is characterized by the contraction of smooth muscle and capillary dilation. These reactions are caused by the release of certain substances such as histamine, bradykinin, serotonin, and slow-reacting substance in response to the reaction of the antigen with a mast cell-fixed antibody, chiefly IgE. This term is sometimes used to refer to the severe form of the reaction called {anaphylactic shock}. --[Stedman] [PJC] |
