[Comparative evaluation of morphofunctional organization of vertebrate nuclear blood cells].
Morphometrical parameters, osmoregulatory possibilities, and the membrane reserve value of nuclear hemocytes (leukocytes and erythrocytes) were studied in the main classes of vertebrates by using method of hypoosmotic loads. It has been established that in the fish--mammals line in erythrocytes the absolute reserve of the plasmalemma decreases and the relative area of the cell surface increases. Evolution of leukocytes is accompanied by an increase of the membrane reserve and of the surface area due to a decrease of volume and to a rise of folding of the plasmalemma.
