title: Adrenal cortex of rat: diurnal variation of nuclear volumes and mitotic index of cells in zona fasciculata.
abstract: 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.
