Correlations of intracellular and cellular regeneration of the epithelium of the kidney tubules in necronephrosis

: The study of radioautographs in ultrathin and semithin sections extracted from animal tissues and following the impulsive as well as long-term injection of 3H-thymidine was made. Intracellular regeneration processes (external cell membrane synthesis, DNA reparation, restoration of the lost albumin-synthesizing complex and cytoskeleton) turned to develop in proximal canals of epithelial cells. The processes were aimed at the liquidation of distortions preventing cell from entering mitosis.
