7.Defective condition of organism in case of allergy (asthma)
reactivity of tissues to allergens
cause of allergic diseases is a hypersensitive reaction of organism
to the agents, which are normally present in the environment. The
first contact of organism with agent, which act as an allergen, may
(in case of some people) results into the production of IgE antibody
against those allergens. The next contact with the above mentioned
allergen, trigger an allergic reaction in the organism. It is a
complex reaction frequently mediated by an agent – histamine.
Allergic reaction may affects different organs and organ systems
(olfactory membrane, conjunctivas, bronchus -asthma, skin).
triggering of the complex reaction in affected tissue mediated by
neurodermatitis, swelling of oedema, increased secretion of mucous
membrane, flush, the formation of exanthems
