[Morphological peculiarities of peripheral blood lymphocytes in arctic foxes after administration of various doses of vitamins A and E].

The aim of this work was to study the effect of various doses of vitamins A and E on the morphometric parameters and surface architectonics peculiarities of peripheral blood lymphocytes in veiled Arctic foxes. Using light microscopy, it was found that in the blood of veiled Arctic foxes (n=30) most of the lymphocytes had relatively smooth surface, and only in some cells cytoplasmic protrusions were observed. Large doses of vitamins A and E that were introduced into animal diet, caused significant reduction of morphometric parameters in relatively smooth forms of lymphocytes, while vitamin A changed the microrelief of their surface.
