The purpose of the work was to study the effect of high-intensity laser exposure in the therapeutic mode on the morphofunctional state of rat thymus. Material and methods. The experiment was carried out on 54 rats, divided into 2 groups: control (intact animals) and experimental – a single exposure of laser radiation on the thymus region (970 nm, 1 W/cm2 IRE-Polus, Russia). Extraction from the experiment and material sampling were carry out after 1 hour, 1, 3, 7 day after exposure. Histological sections stained with hematoxylin-eosin were study using digital morphometry. Results. A single laser exposure on the thymus led to a change in the relative area of the functional zones of the thymus and their cell density, as well as an increase in the number of Gassal’s bodies in the thymic slices and an increase in the relative area of the vascular channel.
