Training performed with the simultaneous correction with diucifon resulted in the changes that were indicative of the increased reserve capacity of the immune system (increase in the relative area of the cortex in thymus sections, augmentation of the number of blast cells, medium lymphocytes and mitotically dividing cells). The degree of these changes was different in animals with various adaptation capacity, which is indicative of the necessity of immunomodulator administration considering an individual organism response to physical loads. 5 weeks after cessation of the training, in 75% of animals that were trained without correctrion, the signs of thymic involution (increase in the amount of adipose tissue, thickening of interlobular septae) were more expressed than in the animals of control group. In rats that received diucifon, thymus structure and cellular composition were similar to those in the control group. | lld:pubmed |
