[The effect of ultraviolet-irradiated blood on bronchial hyperreactivity in bronchial asthma patients].

Clinical investigation was carried out with the view to study the effect of ultraviolet-irradiated autoblood on bronchial spasm induced by acetylcholine in 11 patients with moderate and severe bronchial asthma in out-of-attack period. Reinfusion of autoblood was established to reduce bronchial hyperresponsiveness in asthma thus allowing to control one of the main pathogenetical mechanisms.
