Nasal mucociliary clearance and ciliary beat frequency in cystic fibrosis compared with sinusitis and bronchiectasis.
Nasal ciliary function and mucociliary clearance were studied in patients with cystic fibrosis and in three control groups. Ciliary beat frequency and nasal clearance time were measured in groups of 10 subjects with cystic fibrosis, sinusitis and bronchiectasis and age and sex-matched control subjects. Ciliary beat frequency was also measured in normal subjects matched as bronchiectasis control...
متن کاملSputum and mucociliary clearance mechanisms.
Bronchial secretion forms a periciliary liquid layer and may also give rise to thicker secretion that moves on the tips of the cilia. This latter material as collected at bronchoscopy or coughed up as sputum is a viscoelastic substance behaving in a characteristic way over a wide range of shear rates. The anatomical basis of secretion is described and its control as established by organ culture.
متن کاملMeasurement of nasal mucociliary clearance.
The saccharin test was carried out in a randomly selected sample of schoolchildren (142 boys and 153 girls, age range 11-14 years) to determine the variability and reproducibility of the test and to assess whether it could be used as a screening test for nasal mucociliary clearance. Nasal mucociliary clearance times were analysed according to clinical history (asthma, rhinitis, asthma with rhin...
متن کاملMeasurement of Nasal Mucociliary Clearance
Mucociliary clearance (MCC), a vital key defense mechanism is especially important in the upper airways and sinuses, as it protects the body against noxious inhaled materials [1]. The removal of debris-laden mucus in the sinuses completely depends on MCC, whereas in the lower airways, MCC can be compensated for by other mechanisms like coughing [2]. The nasal mucociliary clearance (NMC) system ...
متن کاملImpaired 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...
