An Observation of the Mucociliary Transport in a Bird's-eye View

Abstract

Mucociliary movement and transport features were studied in bird's-eye view using a microzoom light microscope, in addition to the photoelectrical analysis.
The movement of charcoal powder in the superficial layer was smooth without the influence of the ripplelike mucus undulation, while dryness of mucus decreased markedly mucociliary activity. These phenomena could be recorded successfully as TV images.
On the basis of the results obtained, this new technique was useful as one of the dynamic studies of the mucociliary function.
