[Structural changes in the thymus and spleen of white rats during the recovery after long-term physical loading].
In the experiment on 30 outbred rats, subjected to systemic long term physical loads it was shown that unfavourable changes in immune system organs may arise not only affected by acting loads but also during repair after their finishing. 2 weeks after sharp ceasing of exercises increase of involutive changes in lymphoid organs (reduction of thymus and spleen sizes, disappearance of lymphoid nodules with germinative centers in spleen and great number of degenerating cells) so as decrease of the organism resistance were found. This was suggested by growth of pathogenic microflora colonies on the agar. In gradual reduction of physical load it was managed to escape from unfavourable changes in both organs.
