考氣喘的early、late response,記得複習兩者差別~Egan's 11th p.525~526"When a patient with asthma inhales an allergen to which he or she is sensitized, the antigen cross-links to specific immuno-globulin E (IgE) molecules attached to the surface of mast cells in the bronchial mucosa and submucosa. The mast cells degranulate rapidly (within 30 minutes), releasing multiple mediators including leukotrienes (previously known as slow-reacting substance of anaphylaxis [SRS-A]), histamine, prostaglandins,platelet-activating factor, and other mediators."
