Cytological and morphometric peculiarities of blood cells of triton before and after the total resection of limbs

The results of cytologic and morphometric anal-ysis of cells of peripheral blood in needly newt be-fore and after the resection of limbs are given in the study. It was established that needly newts had lymphocytic profile of blood which did not change after total resection of limbs; neutrophil reaction after the loss of limbs at tritons was missing. The total number of erythrocytes and leukocytes de-pend on physiological condition of tritons and changes in the course of post-traumatic regenera-tion. Blood cells of needly newt have cytologic and morphometric features depending on the stage of post-traumatic regeneration. In erythrocytes of pe-ripheral blood nuclear and cytoplasmatic relation, thus the area of erythrocytes in the animals of re-generation stage significantly decreases three times. In the animals without limbs and being in process of post-traumatic regeneration, the sizes of lymphocytes considerably increase in comparison with the intact. After total loss of limbs erythrocytes, on the contrary, decrease in sizes, their form be-comes more various. Nuclear and cytoplasmatic ratio in erythrocytes in the course of post-traumatic regeneration increases testifying to the activation of hematopoietic stem cells in the red bone marrow
