Document Summary
Degranulation of many mast cells @ once causes the release of large amounts of histamine and inflammatory mediators. Can result in acute anaphylaxis or anaphylactic shock. Anaphylactic shock is an especially dangerous type of llergic reaction. Can be counteracted (temporarily) with injections of epinephrine which neutralizes many of the mechanisms of anaphylaxis, relaxes smooth muscles and reduces vascular permeability. This provides time to get the emergency medical help the patient needs. Drugs- antihistamines neutralize histamine, asthma can be treated with an inhalant containing corticosteroid and a bronchodilator. Is a form of treatment to reduce the allergic reaction. Consists of a series of injections with a solution containing the allergen that causes the allergic symptoms. Facts about the relationship between clean environment and allergy: lower incidence of allergy in those living in rural areas. Lower incidence of allergy in the younger children of large families. Lower incidence of asthma in children who go to day care.
