title: Effect of constant light and darkness on the mitotic activity of adrenal cortex undergoing adrenal regeneration or compensatory growth in male Wistar rats.
abstract: The effect of constant light and darkness on the mitotic activity of the adrenal cortex in the course of adrenal regeneration and compensatory growth in male Wistar rats was investigated. Three separate experiments were performed in different seasons. It was found, that on the tenth day of both regeneration and compensatory growth, constant darkness decreased the mitotic activity of the adrenal cortex, and in contrast, constant light had no significant effect when compared with the controls.
