[The ultramicroscopic characteristics of the cells of the thymus and of the inguinal lymph nodes in white rats subjected to intensive physical loading after preliminary training and without it].
Single physical load (fifty minutes long swimming with further increase) causes destructive changes in the immune system organs, demonstrated on the cellular level--increase of perinuclear space, appearance of vacuoles in the cell cytoplasm and destruction of mitochondria cysts. Five weeks long preliminary training of the animals with six times a week use of continuously increasing physical loads contributed in appearance of lymphocytes with altered shape of the nucleus: great number of mitochondria, many with destructed cysts was found. Besides, cells with signs of destruction were demonstrated. The use of the same volume physical load for a more long time during the training and correction of the diet with vegetable products, containing biologically active substances helped to prevent unfavorable changes on the cellular level.
