THE CELLULAR STRUCTURES OF THE CORTICAL AND MEDULLA OF THE THYMUS OF RATS IN THE PERIOD OF POSTNATAL ONTOGENESIS ARE NORMAL AND EXPERIMENTALLY EXPOSED TO ENDOGENOUS

Abstract

The article presents the data of a study conducted on rats with EN, the cellular structures of the cortical and medulla of the thymus during the period of postnatal ontogenesis in the control group and in an experiment under the influence of EN. The study of the cellular structures of the cortical substance of the thymus of rats revealed that the number of lymphocytes, macrophages and dendritic cells increased at all ages of the experiment and the largest increase was detected by 3 months of age to 32.4%. An increase in the Ghassal bodies in the experiment was detected at 30.0% in relation to the control group at 1 month of the experiment. In the cerebral layer of the rat thymus, an increase in the number of lymphocytes, macrophages and Ghassal corpuscles was revealed by 33.3% at 1 month of age. By age 3 of the experiment, an increase in dendritic cells by 28.6% was detected.
