[Effect of adrenergic and histaminergic disorders on the subclinical course of atopic bronchial asthma].

To characterize membrane-receptor peculiarities of the adrenergic and histaminergic systems under the model of peroxide and hyperosmolar effect in atopic bronchial asthma (ABA) and preclinical stage of BA, we have examined 25 patients with ABA, 19 patients with nonpulmonary allergy, 28 healthy men and 21 healthy blood relatives of ABA patients. The phenomenon of inversion of the effect of beta-adrenoblocker (obzidan) and of the combined effect of histamine and H1-antagonist (dimedrol) was revealed in ABA patients. The same phenomenon was registered at the preclinical stage of BA. In ABA and in preclinical BA the shift of H1/H2-histaminergic balance to increased H1-activity exists. Peroxide and hyperosmolar effects modeled on red cell membranes allowed us to characterize reactivity of adrenergic and histaminergic systems not only in ABA but also in preclinical BA.
