[Adrenergic and cholinergic structures of guinea pig lungs under normal conditions and in experimental bronchial...

Fluorescent and histochemical methods were applied to the study of the morpho-functional condition of the adrenergic and cholinergic nervous system of the bronchopumonary apparatus in guinea pigs under normal conditions and during sensitization (subcutaneous and inhalant) with tick Dermatophagoides pteronyssinus ticks. There was revealed a marked excitation of the adrenergic nervous system, and a reduction of the acetylcholine esterase activity in the bronchopulmonary tissue during the animal sensitization.
