Mucociliary transport in trachea of patients with cystic fibrosis.
Mucociliary tracheal transport rates were measured in 20 patients with cystic fibrosis, in whom these rates ranged from 0 to 12.8 mm/min. The patients were divided into 3 roughly equal groups on the basis of their transport rates. (1) Those in whom no abnormality in mucociliary transport was detected in the trachea; (2) those in whom normal transport rates were measured but in whom abnormalitie...
متن کاملMucus, phlegm, and sputum in cystic fibrosis.
Although some clinicians still believe that cystic fibrosis (CF) lung disease is largely due to hypersecretion of very viscous mucus, it has never been demonstrated that there is mucus hypersecretion in CF and it is clear that there is almost no intact mucin (the principal polymeric component of normal mucus) in CF sputum. CF sputum has lower viscosity when compared to asthma or bronchitis sput...
متن کاملRevisited physicochemical and transport properties of respiratory mucus in genotyped cystic fibrosis patients.
We investigated the physicochemical and transport properties of sputum samples collected in physiotherapy from a well-documented group of 27 cystic fibrosis (CF) patients with identified CF genotypes. Sputum samples were characterized ex vivo for their water content, surface properties (surface tension and contact angle), rheologic properties (viscosity and elastic modulus), and transport prope...
متن کاملMucus Distribution Model in a Lung with Cystic Fibrosis
Cystic fibrosis (CF) is the most common autosomal recessive disease in Caucasians with a reported incidence of 1 in every 3200 live births. Most strikingly, CF is associated with early mortality. Host in flammatory responses result in airway mucus plugging, airway wall edema, and eventual destruction of airway wall support structure. Despite aggressive treatment, the median age of survival is a...
متن کاملCFTR, mucins, and mucus obstruction in cystic fibrosis.
Mucus pathology in cystic fibrosis (CF) has been known for as long as the disease has been recognized and is sometimes called mucoviscidosis. The disease is marked by mucus hyperproduction and plugging in many organs, which are usually most fatal in the airways of CF patients, once the problem of meconium ileus at birth is resolved. After the CF gene, CFTR, was cloned and its protein product id...
