[Changes in the structural components of the thymus gland with different degrees of adaptation of the body to physical loads].
The thymus has been studied by means of histological and morphometrical methods in 167 male white rats subjected to various regimens of physical loadings. The physical loading is accompanied with certain changes in relationship of the thymus structural components. These changes are slightly depended on the loading regimen, but essentially vary in animals that differently adapt to the loading. When adaptation is sufficient, the areas occupied by the thymus connective tissue components decrease, while the part of the cortical substance increases. This demonstrates certain activation of immune processes in these animals. An insufficient adaptation produces an acceleration of age involution of the thymus and results in decreasing immunological reactions of the organism.
