- Abstract
The article presents the results of experimental studies of interscapular and peri-adrenal brown adipose tissue of rats kept at low temperatures. Experimental animals were kept at a temperature of + 50 °C for 1.3, 7, 15, 30, 90 days. The skin temperature of the lateral surfaces of the body, ears, paws, tail, interscapular and rectal regions was measured to assess the overall body reactions. The studies made it possible to clarify and detect some morphological features of brown adipocytes in the processes of adaptation to cold. Changes in cell structure occurred in three periods: acute (1 day), transient (3–15 days) and period of steady adaptation (30–90 days). Morphometric studies of brown adipocytes of interscapular and near-adrenal brown adipose tissue showed that with an increase in the duration of stay under conditions of low temperatures, the number of destructive types of brown adipocytes decreases, cells activity increase of types II and III is observed. Under low temperature conditions, brown adipose tissue cells are rapidly incorporated into the thermoregulation and heat production process. The findings show adaptive mechanism effect for brown adipose tissue cells.
