Impaired tracheobronchial clearance in bronchiectasis.
Tracheobronchial clearance was measured by a radioaerosol technique in 12 patients with bronchiectasis, seven patients with chronic obstructive lung disease expectorating mucoid sputum daily (group X), eight patients with chronic obstructive lung disease but negligible sputum expectoration (group Y), and 10 healthy subjects. The patients with bronchiectasis all expectorated purulent sputum dail...
متن کاملImpaired tracheobronchial clearance in patients with mild stable asthma.
Tracheobronchial mucociliary clearance was measured with the radioaerosol technique in 25 patients with stable, mild asthma, none of whom was taking systemic corticosteroids. The results were compared with those obtained from a control group of 25 healthy subjects matched for age and sex. All patients and healthy subjects were non-smokers. Ventilatory function was significantly impaired in the ...
متن کاملEffect of temazepam on tracheobronchial mucus clearance.
BACKGROUND Tracheobronchial clearance of mucus from the lungs is reduced during sleep and, usually, by the administration of opiates. It seemed possible therefore that temazepam, a widely used potent benzodiazepine, retarded clearance. METHODS The effect of 10 mg temazepam on mucociliary clearance was studied in eight healthy volunteers, aged 18-50 (mean 30) years, in a randomised, placebo co...
متن کاملSevere tracheobronchial stenosis and bronchiectasis complicating ulcerative colitis
A 37-year-old woman with a 20-year history of ulcerative colitis (UC) was admitted with complaints of cough and increasing sputum production. Chest computed tomography showed severe stenosis of the left main bronchus and bronchiectasis of the left lower lobe. Biopsy specimens from the area of bronchial stenosis showed chronic inflammation with lymphocyte infiltration, and we diagnosed respirato...
متن کاملTracheobronchial deposition and clearance in small airways in asthmatic subjects.
Asthma tends to impair mucociliary clearance, as assessed from measurements in large airways. However, very little is known about clearance in the smallest airways of the tracheobronchial region. Deposition and clearance was estimated in 11 subjects with stable asymptomatic asthma and 10 healthy subjects after inhalation of 6 microns (aerodynamic diameter) monodisperse Teflon particles labelled...
