A preliminary study of nasal mucociliary clearance in smokers, sinusitis and allergic rhinitis patients.
Mucocillary clearance of nasal mucosa was evaluated with the saccharin test. A total of 140 subjects was divided into 4 groups: smokers, allergic rhinitis patients, sinusitis patients, and a normal control group. The mean mucociliary transit time for the normal control group (n = 40) was 12 minutes, while allergic rhinitis patients (n = 40) had a mean of 14.6 minutes. The smoker group (n = 40) ...
متن کاملMucociliary clearance in patients with chronic autonomic failure.
Mucociliary clearance was measured in four patients with chronic autonomic failure and normal ventilatory function using a method of scanning the clearance of inhaled polystyrene particles tagged with 99mTc. Previous surgical and experimental evidence has suggested that autonomic denervation might be expected to impair clearance. However, the four patients in this study showed no significant di...
متن کاملNasal 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...
