- n. (Med.) hypersensitivity (to a protein or drug) resulting from prior contact with a substance.
- n. (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 reaction called

“Research: Expanded research on food allergy and anaphylaxis is necessary to understand why the prevalence of food allergy is increasing, as well as how to prevent and treat food allergies.”
“Seen in these terms, anaphylaxis is an universal defence mechanism against the penetration of heterogenous substances in the blood, whence they can not be eliminated.”
“This local effect of anaphylaxis is often called the "Arthus phenomenon".”
“Once these first factors in anaphylaxis were well grounded, the field opened right up, thanks to the skilled and fruitful research of many investigators.”
“There can be no question of real anaphylaxis, for anaphylaxis is always severe, immediate and terrible, whereas in this instance, the leucocytosis only appeared on the third or the fourth day.”
“If the anaphylaxis is slight, only symptoms of itching, excitation and heightened breathing appear.”
“Two further series of observations I have made quite recently do lead me to question the hard and fast rules for specificity in anaphylaxis one is tempted to lay down.”
“Alimentary anaphylaxis is characterized by the antigen, whether alimentary or not, being introduced into the organism by means of the digestive tube.”
“Even in the first of these three cases (A + A) where the anaphylaxis is strictly alimentary, for the initial ingestion as well as the subsequent ingestion, there is no doubt about anaphylaxis having taken place.”
“If you experience one of these strong allergic reactions to an insect bite or contact, you could develop anaphylaxis, which is a severe whole-body allergic reaction to a protein from the bug.”

These come from gamma meditation ,I think.
