Direct Measurement of Directional Disorder for Ciliary Metachronal Wave

Abstract

The interrelationship of cilia and the directional disorder of ciliary metachronal wave were analyzed using digital microscopic images. The degree of synchronization between ciliary beats was determined by the correlation factor between two different spots. Principal axes of inertia were applied to find out the uniphase directions of beating cilia. The standard deviation of wave directions in an ROI was defined as a measure of ciliary wave disorder (CWD). The pooled mean of CWD was 22.9+/-8.73 deg in ROIs of 8 micrometers x 8 micrometers and 25.4+/-6.46 deg in 32 micrometers x 24 micrometers from the sphenoid sinus mucosa of 5 normal subjects. Our result shows that there is a considerable variation in metachronal wave directions of cilia beating on the epithelium.
