[The thymus in exposure to pain].
The effect of isotonic solution and microtrauma of the gastrocnemius muscle to the structure and cell composition in various zones of the thymus has been studied on mature white male rats on the first, 7th and 14th days of the experiment. At injection of the isotonic solution (sodium chloride) the part of small lymphocytes decreases and that of the large and middle ones--increases (it is mostly manifested on the 7th day of the experiment). The amount of immature plasma cells increases sharply at the same time, and that of mature cells--fluctuates during the experiment. The number of the mitotically dividing cells decreases. To some extent grows the part of the reticuloepitheliocytes; this demonstrates that migration of the lymphoid line cells from the thymus becomes greater. Pricks of the syringe needle do not produce any statistically significant changes.
