title: [Disorders of cellular regulation systems as a basis for changed bronchial reactivity in bronchial asthma].
abstract: Leukosuspensions from 217 patients with bronchial asthma and 73 normal subjects were examined for alterations in the levels of cAMP and cGMP under the effect of incubation with adrenaline, propranolol, acetylcholine. A study was also made of the activity of cAMP PDE and glycogen metabolism. Simultaneous measurement of the basal and stimulated levels of cyclic nucleotides and their ratios revealed a decrease in cell adrenoreactivity and a rise in cholinoreactivity. Variation of the beta-adrenoblocking action of propranolol typical for the atopic mechanism of bronchial asthma was demonstrated. Comparison of the adrenodependent glycogenolysis and alterations in the cAMP level, analysis of the action of analgin on these characteristics allowed the conclusion about the secondary nature of alterations in cAMP metabolism dependent on the features of prostaglandin metabolism. A significant decrease in the adrenodependent glycogenolysis was revealed in lymphocytes, with that decrease induced by drug, dust and pollen allergens. It was demonstrated that in verified viral infection, cAMP PDE was significantly reduced.
