Cytodynamics in the respiratory tract of the rat.

The knowledge of cytodynamics in the respiratory tract is still in its infancy. Since Bertalanffy and Leblond (1953) described their findings in a study of the alveolar macrophage cells in the lung of the albino rat, few investigations have been reported in the literature (Koburg, 1962; Spencer and Shorter, 1962; Meyer zum Gottesberge and Koburg, 1963; and Shorter, Titus, and Divertie, 1964b), and these have indicated that the findings may vary greatly in the epithelia in the various parts of the respiratory tract, even between areas in close relationship to one another. The purpose of this paper is to report the findings obtained in
