Morphofunctional features of lymph nodes, thyroid gland and testis of rats during adaptation reactions to stress and activation

The morphofunctional state of lymphatic nodes, thyroid gland and testis have been studied with morphometric, cell photometric and biochemical methods in experiments on adult white rats under the influence of nonspecific adaptation stress and activation reactions caused by small doses of adrenaline (125 mg/kg and 5 mg/kg). The research showed that the changes in the structure and function of the lymphatic organs under stress and activation were markedly different. If stress results in depression of functional state of these organs, the activation reaction, on the contrary, stimulates it.
