MORPHOMETRIC PARAMETERS OF ADRENAL GLANDS OF WHITE RATS BY KEEPING IN CONDITIONS OF NATURAL AND ARTIFICIAL PHOTOMODES

This article examines the morphometric parameters of the adrenal glands of male and female white rats in different seasons of the year. Sexual distinctions have been revealed both in the total area of the adrenal glands and in the areas of their zones. The area of the zones of the adrenal glands of the females was higher in comparison with the males. Especially strongly these distinctions revealed themselves during the winter period. In this season of the year all the examined morphometric parameters (volume of cells, volume of karyon, volume nucleolus) in all the zones of the adrenal cortex were higher in the females in comparison with the males. In the reticular layer the studied morphometric parameters were also higher in the females during the transitive seasons of the year (spring and autumn). In the adrenal medulla the studied morphometric parameters were higher in the females in comparison with the males in each season of the year. In conditions of dark deprivation in the animals of both sexes was observed an increase of the total area of the adrenal cortex and the adrenal medulla. In the zona glomerulosa and reticular layer of the males in conditions of dark deprivation was observed an increase in the volumes of the cells, karyon and nucleolus, and in the zona fasciculate there was only an increase in the nucleolus volumes. In conditions of light deprivation in the males there was a decrease in the area of the adrenal cortex. Light deprivation did not influence the total area of the adrenal cortex and adrenal medulla of the female adrenal glands. In the females by both types of deprivations there was an increase in all the studied parameters in the zona fasciculate, while in the zona glomerulosa there was only an increase in the nucleolus volumes. In the male adrenal medulla under the influence of dark deprivation there was an increase in all the studied morphometric parameters.
