Ciliary beat frequency in transplanted lungs.

Ciliary beat frequency in transplanted lungs.

BACKGROUND Patients with lung transplantation are prone to respiratory infections. Generally this is attributable to the effects of immunosuppressive drugs but mucociliary clearance has been found to be impaired in these subjects. A study was performed to determine whether this finding is accompanied by a reduction in ciliary beat frequency (CBF). METHODS Six patients who had undergone single...

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...

Ciliary beat frequency in human bronchi and bronchioles.

STUDY OBJECTIVE This study aimed to determine the differences between ciliary beat frequencies of respiratory ciliated cells from peripheral bronchioles and from proximal bronchi in humans. DESIGN Measurements were made from resected lungs. Ciliated cells were harvested by brushing the mucosa of each site immediately after surgery. Brushings with a cytology brush were performed on normal area...
