CHANGES IN THE MORPHOMETRIC PARAMETERSOF THE ADRENAL CORTEX OF MARAL DOES DURING THE YEAR
The paper studies the histological structure of the adrenal cortex in non-pregnant sexually mature maral does in different seasons of the year (exemplified by animals living on the free-range farms of the Altai Republic). The greatest thickness of the adrenal cortex is observed during winter. The minimum thickness of the zona glomerulosa is typical of summer, while in autumn the cell size increases significantly. The zona fasciculata expands during winter, reaching minimum dimensions in spring. The minimum thickness of the zona reticularis is identified in winter; its cells and nuclei decrease statistically significantly in size during this season compared to autumn.
