HISTOTOPOGRAPHIC AND STRUCTURAL FEATURES OF CANINE THYROID GLAND FOLLICLES UNDER SINGLE DYNAMIC MOTOR LOADS

The formation of urgent and long-term adaptation the organism under various modes motor loads is provided by a change in activity thyroid gland, functional unit which follicle. An accurate assessment morphological parameters follicles different histotopographic zones gland provides researcher with objective information about state organ. purpose study was to evaluate effect single training, starting limiting (treadmill running) on ​​the structural features dogs. On transverse sections right lobe dogs, stained hematoxylin-eosin, area were measured. measurements carried out (central, intermediate, peripheral), distinguished relative its geometric center. Animals studied control group (16 male dogs) experiment (31 animals), which, as result loads, response formed, manifested changes gland. studies showed that muscle leads activation units organ - follicles. transformation durations obligate involvement peripheral zone significant decrease ​​follicles, an increase number functionally more active small area, due predominantly large medium follicles, colloid-epithelial areas ratio. Depending dynamic two ways primary revealed: either (large, medium, small), or their ratio peripheral). Modeling can be used analyse influence reorganization experiment. constant variability found present may associated special conditions blood supply from capsule.
