Nasal mucociliary clearance and salmeterol
Clinical Otolaryngology and Allied Sciences, 1997In vitro studies have suggested that beta 2-adrenergic agents increase the ciliary beat frequency in human respiratory epithelium. We carried out a randomized, double-blind placebo-controlled trial to investigate the effects of a topical spray, salmeterol, on nasal mucociliary clearance using the saccharin test.

Tracheal Resection and Mucociliary Clearance
Annals of Otology, Rhinology & Laryngology, 1976Mucociliary transport following tracheal resection and end-to-end anastomosis was evaluated in beagle dogs, using the movement of 99M TC labeled sodium pertechnetate solution as a marker. Preoperatively, mucociliary clearance was stable, but a three-fold decrease in tracheal mucus movement ...

Theophylline and mucociliary clearance
Chest, 1987Abnormal mucociliary transport is improvement by the action of theophylline, and this effect can be attributed to several mechanisms. The drug may directly and indirectly mediate the increase in the secretory output of bronchial glands, and this effect is enhanced by the vagal gastropulmonary reflex which is stimulated by the irritant action of ...

Mucociliary clearance: pathophysiological aspects
Clinical Physiology and Functional Imaging, 2013SummaryMucociliary clearance has long been known to be a significant innate defence mechanism against inhaled microbes and irritants. Important knowledge has been gathered regarding the anatomy and physiology of this system, and in recent years, extensive studies of the pathophysiology related to lung diseases characterized by defective mucus clearance

The Effects of Ethanol on Mucociliary Clearance
Alcoholism: Clinical and Experimental Research, 1985Mucociliary clearance by the in vitro frog palate can be used as a model to study such clearance by mammalian lung. Frog palates bathed in Ringer's solution exhibited a constant mucociliary clearance rate for over 2 hr. When the bathing solution was exchanged for one containing ethanol, the mucociliary clearance rate was de‐tectabty inhibited by 300 mg/

Mucociliary Clearance in Adult Asthma
American Review of Respiratory Disease, 1992Abstract Severe impairment of mucociliary clearance (MC) in hospitalized asthmatics has recently been demonstrated in peripheral and central airways. MC was also shown to improve with clinical recovery and hospital discharge (2). In the present study, we measure MC in chronic, stable asthma in subjects with a wide range of obstruction

Mucociliary Clearance in the Trachea
Clinics in Chest Medicine, 1986Tracheal mucociliary clearance is governed by the interplay between ciliary activity and secretory functions of the epithelium. These functions are altered transiently by various physiologic and injurious stimuli, and chronically in asthma, chronic bronchitis, cystic fibrosis, and other forms of airway disease.

Mammalian Respiratory Mucociliary Clearance
Archives of Environmental Health: An International Journal, 1973An in vivo model was designed to provide information on the major factors affecting mammalian mucociliary clearance. It involves simultaneous quantitation of mucous load, tracheal transport velocity, ciliary beat frequency, and rheological properties of mucus. Values in 23 cats were obtained. The results were remarkably consistent for the group as well

Pulmonary Mucociliary Clearance in Cystic Fibrosis
New England Journal of Medicine, 1973Abstract Pulmonary clearance was examined by measurement of the rate of removal of a 99mTc-albumin aerosol (aerodynamic mass median diameter 3 μ) in 13 children with cystic fibrosis. Lung retention of radioactive label was monitored with a scintillation camera interfaced to a data-storage and retrieval system. The results were compared to those of nine
