Allergens are harmless to most people. But when you have hay fever, your immune system thinks the allergen is invading. The immune system tries to protect your body by releasing natural chemicals into your bloodstream. The most important chemical is called histamine. It causes the mucous membranes...
The cells then send out histamine, which causes blood vessels to expand, and other chemicals, and these trigger the allergy symptoms. These antibodies are singled-minded. Each one targets only one type of allergen. That explains why someone might beallergic to peanutsbut not to eggs. You can ...

The seasonal histamine level were higher with the severity of atopy (Erlangen atopy score). There was no significant influence of age and gender. The reduction of allergic symptoms during hyposensitization was not comparable to the degree of seasonal histamine level. Compared with the clinical ...
Histamine promotes the development of eczematous lesions, elevates IgE serum levels, and induces scratching behavior in CACD. The administration of H1 or H4 receptor antagonists was effective to ameliorate these symptoms in murine CACD models. The combination of H1 and H4 receptor antagonists is a...
Multiple cedar pollen challenge diminishes involvement of histamine in allergic conjunctivitis of Guinea pigs. It has been reported that antihistamines do not fully modify symptoms of allergic conjunctivitis in clinical settings, suggesting that histamine is not the... Y Fukushima,T Nabe,N Mizutani,.....
The normal human body contains a certain amount of histamine, which can destroy histamine released by some cells (such as smooth muscle contraction, telangiectasia, increased permeability, etc.). Therefore people who have allergic reactions to certain substances, the symptoms are not obvious, ...
Anti-immunoglobulin E antibody treatment blocks histamine release and tissue contraction in sensitized mice. Inhibition of antigen-specific IgE response has been shown to lead to amelioration of allergic disease symptoms. In an effort to design a therapy aimed at ... M Haak-Frendscho,R Saban,R....

which brought hope in the treatment of allergic diseases and has been in clinical use to this day.24,25In 1953, James F. Riley was the first to discover that histamine in the human body mainly comes from mast cell granules.26Up to this point in history, basic treatment methods for allerg...
