[Electrochemical phenomena in autoregulatory reactions of the blood vessels].

Some physiological mechanisms being in the basis of autoregulatory reactions of blood vessels have been studied. It has been found that the rise in the difference of the potentials of electrochemical origin between inner and exterior vessel surfaces during blood movement facilitates to increase the vessel myogenic reaction at the intravascular pressure rise, to intensify spontaneous bioelectrical activity of smooth muscle cells and hydration of a vascular wall. These phenomena are reproduced by the application to a vessel a constant potential commensurable with one rising during blood movement.
