Histological and ultrastructural changes in rat kidneys in the early period after paraoxone poisoning
Introduction. Toxic nephropathies are not limited to a single morphological type of kidney tissue damage. The widespread distribution of organophosphorus compounds (OPs) in the modern world makes it necessary to study the morphological manifestations and delayed effects of OPs on various organs and tissues of the human and animal body. Material and methods. The article presents the results of a study of changes in the kidneys of rats at the ultrastructural level in the early stages after a single injection of paraoxon at doses of LD50 and LD84. Results. It has been shown that after the introduction of paraoxon, the epithelial cells of the convoluted tubules are initially damaged, and a week after the poisoning, changes are recorded in the renal corpuscle, manifested in an increase in the thickness of the glomerular basement membrane. Limitations. Morphological changes in the renal tissues were analyzed in a single poisoning at doses of LD50 and LD84. Conclusion. The changes detected in the renal corpuscles indicate the feasibility of further studies on the effect of FOS on the nature, sequence and mechanism of nephrotoxic effects of FOS in models of acute and chronic intoxication.
