“…The large temperature diapason (from 0 to 38°C) of the functional activity of the frog biochemical systems implies the characteristic thermotropic properties of the cellular membranes, which pro vide a change of the ionic transport at adaptation to the seasonal temperature course [4]. The goal of this work was to study peculiarity of the frog erythrocyte electrophoretic mobility in relation to the seasonal course of temperatures.…”

Abstract-The peculiarities of frog erythrocyte electrophoretic mobility, coupled to the seasonal course of temperatures, have been studied. At the periods of anabiosis and of burst of hemopoiesis, in the vascular bed there increases the portion of functionally young erythrocytes (up to 22%) with increased values of the cell membrane surface charge. Preparation to winter is accompanied by a rise of the number of circulating functionally worn down blood cells (up to 60%) with low values of the superficial charge and low mobility in electrical field. Use of the cell microelectrophoresis method of evaluation of seasonal activity of frog erythrocytes allows obtaining objective data about the cel lular surface charge and its depending functional cell activity without submitting the erythrocytes to modifying actions.
