From The Collaborative International Dictionary of English v.0.44 [gcide]:
anaphylactic shock \anaphylactic shock\ n. (Med.) a severe form of physiological shock, often having a fatal outcome, caused by an extreme immunological reaction to antigens. It is a severe form of {anaphylaxis[2]}, and is characterized by smooth muscle contraction and capillary dilation throughout the body, initiated by antibodies of the IgE class. It is usually seen when an antigen to which a person has become hypersensitized is injected intravenously or subcutaneously. It is also called {generalyzed anaphylaxis} or {systemic anaphylaxis}, and sometimes {anaphylaxis}. --[Stedman] [PJC]

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]
