ULTRASTRUCTURE OF THE ABDOMINAL PLEXUS OF RATS DURING HERBICIDE INTOXICATION AND TREATMENT

As a result of the study, it was found that poisoning of rats with the herbicide 2,4 - DA for 4 weeks causes a decrease in the number of neurocytes in the celiac plexus, changes the protein synthesizing and energy systems of the cell, and accumulates residual structures in the form of lipofuscin. In the neuroplasm, the number of neurofilaments and neurotubules decreases, the organization of the myelin layer of fibers is disrupted. Changes affect the structure of the intima and media of blood vessels, leading to a violation of their transport function. When rats are treated with Taktivin, they show positive dynamics in the structure of the celiac plexus; the protein-synthesizing system is restored in the nuclei and neuroplasm of a number of cells. In the connective tissue stroma, the ultrastructure of collagen fibers improves, and the number of blood vessels increases.
