title: [Seasonal activity of frog Rana ridibunda erythrocytes by data of electrophoretic mobility].
abstract: The peculiarities of frog erythrocytes 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 28%) with increased values of the cell membrane surface charge. Preparation to hibernation 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 obtained objective data about the cellular surface charge and its depending functional cell activity without submitting the erythrocytes to modifying actions.
