A study was made of the influence of suramin and of a combination of suramin and CCl4 on the ultrastructure of hepatocytes, structural and functional state of lysosomes and functional activity of the rat's liver. The latter was characterized by alanine aminotransferase level in blood. Increasing amounts of autophagosomes as well as lysosomal fusion disturbances were registered 24 and 48 hours after a single suramin administration. The combined suramin and CCl4 administration resulted even in a higher damage of hepatocytes. A decrease in the intralysosomal rate of proteolysis in hepatocytes, was also shown in addition to the impairment of liver functional activity. Some ultrastructural features of compensation of the insufficiency of the hepatocyte vacuolar apparatus were noted during suramin and CCl4 administration. Changes in the nucleolar structure were noticed in hepatocytes administered both suramin and CCl4. It is suggested that these changes may involve a compensatory increase in nucleologenesis due to the decrease in the activity of the protein-synthesizing apparatus in hepatocytes. |
