[Circadian periodicity of the processes of hepatocyte proliferation and hypertrophy in intact rats].
In white noninbred rats hepatocytes have been studied morpho- and cytophotometrically. During evening-night time the volume of hepatocytes, their nuclei and cytoplasm increases, as do the amounts of benuclear and tetra- and octaploid cells. In the morning, on the background of maximal mitotic activity, the amount of the diploid cells increases, and the number of tetra- and octaploid hepatocytes, the volume of the nuclei and cytoplasm decreases.
