OBJECTIVE To investigate differences in mucociliary clearance, histologic characteristics, and surface structure of the bilateral nasal septal mucosa in patients with nasal septal deviation. DESIGN Mucociliary transport was measured by saccharin clearance time in both nasal cavities of 20 patients with nasal septal deviation. Their septal mucosae were taken during septoplasty, and the ciliary...

BACKGROUND & OBJECTIVES Asthma is now regarded as an inflammatory disease and bronchial inflammation may disrupt mucociliary function. Inhaled drugs may act by improving mucociliary function. The aim of the study was to investigate the effect of salbutamol, ipratropium bromide and beclomethasone on mucociliary clearance in patients with chronic stable asthma and to compare the efficacy of these...

Biomarkers providing in vivo quantification of the basic elements of cystic fibrosis (CF) lung disease are needed. A study was performed to determine whether the absorption of a small radiolabelled hydrophilic molecule (Indium-111 (In-)DTPA) would be increased in CF airways. DTPA clearance has been used previously to assess epithelial permeability and may also be useful for quantifying liquid a...

OBJECTIVE To compare the effects of buffered hypertonic and buffered normal saline nasal spray on mucociliary clearance and nasal airway patency. STUDY DESIGN AND SETTING Double-blind trial with subjects acting as their own controls. Tertiary care academic medical center. RESULTS Buffered hypertonic saline and buffered normal saline both improved saccharine clearance times ( P < 0.0001 for ...

OBJECTIVE To compare mucociliary clearance time and quality of life in patients who underwent sinus surgery using conventional and powered instruments, and in patients who were treated nonsurgically. METHODS A total of 151 patients with chronic rhinosinusitis were included. Fifty-four patients were treated conservatively, 48 patients were managed surgically by using conventional instruments a...

Tracheobronchial mucociliary clearance was measured in eight non-smoking patients with asthma in complete remission. The patients were symptom free and required no medication whatsoever for one to six months before assessment. Mucociliary clearance was measured with an objective, radioaerosol technique. For comparison, mucociliary clearance of eight non-smoking, healthy subjects with physical c...

BACKGROUND Whereas cilia damage and reduced cilia beat frequency have been implicated as causative of reduced mucociliary clearance in smokers, theoretically mucociliary clearance could also be affected by cilia length. Based on models of mucociliary clearance predicting that cilia length must exceed the 6-7 microm airway surface fluid depth to generate force in the mucus layer, we hypothesized...
