Peripheral opioidergic regulation of the tracheobronchial mucociliary transport system.
We hypothesized that, in the airway mucosa, opioids are inhibitory neural modulators that cause an increase in net water absorption in the airway mucosa (as in the gut). Changes in bidirectional water fluxes across ovine tracheal mucosa in response to basolateral application of the opioid peptides beta-endorphin, dynorphin A-(1-8), and [d-Ala(2), d-Leu(5)]-enkephalin (DADLE) were measured. beta...
متن کاملMethods for studying mucociliary transport.
UNLABELLED Mucociliary transport dysfunctions can impair the quality of life of patients suffering from chronic rhinossinusitis and lead to severe consequences such as alterations in respiratory physiology or even death as in cases of cystic fibrosis and primary ciliary dyskinesia. Therefore, it is crucial to understand the physiology of the mucociliary apparatus and how its components (cilia, ...
متن کاملMucociliary transport in ICU patients.
OBJECTIVES The objectives of this study were to determine the bronchial mucus transport velocities in ventilated ICU patients and to study the possible role of impaired mucus transport in the development of retention of secretion and pneumonia. DESIGN The patients were studied prospectively in a convenience sample trial. SETTING The study took place at a university hospital. PATIENTS Thir...
متن کاملMucociliary function, ciliary ultrastructure, and ciliary orientation in Young's syndrome.
BACKGROUND Mucociliary clearance is impaired in patients with Young's syndrome (obstructive azoospermia with recurrent sinobronchial disease), cystic fibrosis, and primary ciliary dyskinesia. No defect of cilia or mucus has been detected in Young's syndrome. METHODS Ciliary function and ultrastructure, including ciliary orientation, were studied quantitatively in 20 patients with Young's synd...
متن کاملEffects of nitric oxide in mucociliary transport.
UNLABELLED The airways are made up of ciliated epithelium which secretes mucous, protecting the respiratory tract from particles inhaled during breathing. Its is paramount to understand the physiology and the mechanisms involved in mucociliary activity. Literature suggests that Nitric oxide (NO), especially the one produced by iNOS expression, maintains the mucociliary function and the immune d...
