title: [Dynamics of morphological changes in the epithelial layer of the respiratory tract after endobronchial treatment of suppurative endobronchitis by helium-neon laser irradiation (experimental study)].
abstract: The results of a dynamic examination with the use of an electron microscope of semi- and ultrathin sections of the epithelial lining of the respiratory tract in the experimental dogs under endobronchial treatment of nonspecific endobronchitis with varying doses of low-energy radiation from helium-neon laser are presented. It was proved that the outcomes of regeneration of the bronchial mucosal membrane epithelium under endobronchial treatment of purulent endobronchitis with low-energy radiation of the helium-neon laser much depend both on exposure time (single doses of energy), and multiplicity (cumulative dose of energy), and the period after the laser therapy. The most favourable regeneration takes place under 5-minute (single dose of 4.5 J) radiation with 8 to 9 sessions (cumulative dose of 23.1 +/- 1.5 J). A regeneration most close to the normal condition of the bronchial mucous membrane epithelium is achieved at 2.5-3d months after the onset of the experiment (or a month after the laser therapy).
