Fig. 1From: Rapid changes in mucociliary transport in the tracheal epithelium caused by unconditioned room air or nebulized hypertonic saline and mannitol are not determined by frequency of beating ciliaa Diagram of the experimental setup used for in vitro measurements of mucociliary transport on the tracheal epithelium of perfused lamb trachea. Air-flow was set to 25 L/min and was directed from left to right while mucociliary transport was from right to left. The ultrasonic nebulizer was introduced to the air path before the organ bath. Video-microscopy recordings were made through the heated optical window on the top of the tracheal bath to measure mucociliary transport along the tracheal epithelial surface. b Photo of the in vitro experiment setup with the trachea mounted in the organ bath, with circulation of Krebs–Henseleit solution below. The microscope with coaxial illumination is shown aboveBack to article page
