title: Methodologic considerations in mucociliary clearance and lung epithelial absorption measurements.
abstract: Measurements of mucociliary clearance and lung epithelial permeability are relatively simple to perform, with minimum discomfort to the subjects. Awareness of the factors influencing the outcome of these procedures will help to avoid errors and yield useful information about these two clearance mechanisms from both a physiological and a pathological point of view.
