title: An improved device for frequency recording of tracheal ciliary beat.
abstract: An improved device for frequency recording of cyclic movements on the cellular level is described. The device consists of a modified conventional microscope lit by a laser source, an analyzer comprising a fiber optic transmission system, a photodector, an amplifier, a recorder and a thermostatic equipment, including a thermoprobe. In vitro experiments are reported concerning variation in activity as a function of temperature, with respect to the frequency of ciliary beat in rat ring trachea.
