[Reparative processes in the liver and adrenal cortex of rats following an experimental vascular crisis].
Reparative processes in the liver and the adrenal cortex of hemiadrenalectomized female rats, which sustained an acute circulatory disturbance as a result of orthostasis, were investigated by means of quantitative methods (cytometry, kariometry, nucleolometry, determination of cell content calculation of nucleo-cytoplasmic, nucleolo-nuclear ratios). Common features in regeneration of the organs under study were found. During the first days of the experiments the count of the dying cells increased and simultaneously the quantity of amitoses and binucleated cells in the liver grew. The cell composition of the organs was stabilized by the 15th day in the adrenal gland and by the 45th day in the liver. During the first week after orthostasis mitotic activity of epithelial cells rose in both the organs. Later the regeneration took place at the intracellular level (activation of the nuclear apparatus and hypertrophy of the cell cytoplasm).
