Summary

In adult male Wistar rats (200—230 g), nuclear volumes of cells in the adrenal zona glomerulosa exhibit diurnal variation with the peak values at 12 p.m. — 3 a.m. and the nadir value at 12 a.m. Diurnal variation of the mitotic index is characterized by high values from 9 a.m. to 6 p.m. and low values from 12 p.m. to 6 a.m.
