Sidestream tobacco smoke exposure acutely alters human nasal mucociliary clearance.
Nasal mucociliary clearance (NMC) is a biomarker of nasal mucosal function. Tobacco smokers have been shown to have abnormal NMC, but the acute effect of environmental tobacco smoke (ETS) on nonsmokers is unknown. This study evaluated acute tobacco smoke-induced alterations in NMC in 12 healthy adults. Subjects were studied on 2 days, separated by at least 1 week. Subjects underwent a 60-min co...
متن کاملAdaptation of an amphibian mucociliary clearance model to evaluate early effects of tobacco smoke exposure
RATIONALE Inhaled side-stream tobacco smoke brings in all of its harmful components impairing mechanisms that protect the airways and lungs. Chronic respiratory health consequences are a complex multi-step silent process. By the time clinical manifestations require medical attention, several structural and functional changes have already occurred. The respiratory system has to undergo an iterat...
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 کاملNasal mucociliary clearance in adenotonsillar hypertrophy.
The nasal mucociliary clearance time was studied using Andersen saccharin method in 50 normal children and 50 age and sex matched patients of adenotonsillar hypertrophy, which was repeated one month after adenotonsillectomy. The normal mucociliary clearance time in healthy children was found to be 8.55 +/- 2.11 minutes. A significant impairment in nasal mucociliary clearance time was noted in c...
