title: MORPHOLOGICAL ASSESSMENT OF NATIVE MALE SUBJECTS' THYROID BODY IN THE REPUBLIC SAKHA (YAKUTIA) IN DIFFERENT SEASONS.
abstract: Morphological analysis of macro-, microstructures of native male subjects' thyroid gland in the Republic Sakha (Yakutia) in different seasons has been conducted. Macromorphometric indicators of native male subjects' thyroid gland (specific weight, total capacity, linear indicators were specified in summer and winter seasons. Micromorphometric characteristics of structural components of native male subjects' thyroid gland tissue was given in relation to different seasons. In this case native male subjects' thyroid gland was as curtained as normoplastic mixed type of structure, indicators of outer and inner thyroid gland follicles diameter in winter period were slightly bigger than in summer period. The same tendency was observed when thyroid gland follicular-colloidal index was calculated. On the data obtained the attempt to assess season temperature factor impact on the thyroid gland structural indicators were made. This assessment might be used as morphological equivalent of the body adaptation processes in northern regions.
