Effect of Cilia Beat Frequency on Muco-ciliary Clearance
Background: The airway surface liquid (ASL), which is a ï‚uid layer coating the interior epithelial surface of the bronchi and bronchiolesis, plays an important defensive role against foreign particles and chemicals entering lungs.Objective: Numerical investigation has been employed to solve two-layer model consisting of mucus layer as a viscoelastic fluid and periciliary liquid layer as a New...

متن کاملEffect of cigarette smoking on nasal mucociliary clearance and ciliary beat frequency.
Despite the in vitro ciliotoxicity of tobacco smoke and the abnormal mucociliary clearance found in smoking related chronic bronchitis, studies of mucociliary clearance in healthy smokers have produced variable results. The nasal mucociliary clearance of saccharin and the in vitro nasal ciliary beat frequency were studied in healthy smokers and non-smokers. One of 29 smokers had a nasal mucocil...
متن کاملEffects of Aging on Nasal Mucociliary Clearance
Nasal mucociliary clearance is a primary physiological defense mechanism of upper as well as lower respiratory tract, and thus maintains the state of health of the respiratory tract. Any disturbance in number or movement of cilia and change in character or amount of mucus production leads to an altered nasal mucociliary clearance. The present study was undertaken to study the effect of aging on...
