The inguinal lymph nodes (ILN) of 35 mature dogs were studied. Single individually dosed physical load causes destructive changes in ILN both on cell (widening of the perinuclear region, appearance of the great amount of vacuoles in cytoplasm, destruction of the mitochondria christal, rupture of the nuclear membrane) and tissue level (increase of the number of degeneratively changed cells, decrease of the number of the medium lymphocyte). Activity of succinate and lactate-dehydro-genases and alcaline phosphatase increases, with irregular distribution of the reaction products in the ILN section. Systematic training of the animals with such loads not only prevents unfavourable changes in ILN but also results in the increase of the proportion of blast cells, number of cells with the mitotic figures, appearance of the great amount of the lymph nodules with germinal centres. Enzyme activities in ILN of these animals were lower and had an even distribution of reaction products. |
