title: Ciliary beating frequency of frog palate and rat trachea explants under continuous perfusion.
abstract: Rat trachea and frog palate explants were continuously perfused for 2 hr with 199 tissue culture medium. The ciliary beating frequency of the frog palate exhibited fluctuations twice as large as compared to the rat trachea. The rat trachea model should be preferred to the frog palate for long-term studies on ciliary beat frequency.
