[A functional-morphological study of the mucociliary system at stages in the disease in patients with chronic bronchitis].

Combined morpho-functional study of the mucociliary system in patients with chronic bronchitis at different stages of its development was made. Regional mucociliary clearance was evaluated by dynamic aerosol scintigraphy and electron microscopy. Radiography of bronchial biopsies was performed, rheological properties of bronchial content were also determined. Special characteristics of mucociliary main chains were established at each stage of chronic bronchitis development as well as depending on the type of bronchitis, bronchial tree level and phase of the disease. New hypothesis on chronic obstructive bronchitis genesis was substantiated.
