Summary

Diurnal variation in nuclear volumes of cells in the adrenal zona fasciculata was observed in adult male Wistar rats (200—230 g) with a peak level at 24.00—03.00 and the lowest level at 09.00. There was found a diurnal variation in mitotic index with a peak value at 06.00—09.00 and a trough at 18.00—24.00.

Key words

Diurnal variation - adrenal cortex - nuclear volumes - mitotic division
