The influence of electrokinetic phenomena arising from blood movement on reactivity of blood vessels has been studied. The potential difference, as it has been established, occurs during blood movement along a vessel between its internal and external surfaces, being dependent upon the rate of blood movement, and the internal one becomes negatively charged. Blood movement facilitates penetration of molecules of dye with a positive charge into a vessel wall. The contractile response of a vessel to the stimulation of vasomotor nerves gradually increases with a start of blood movement and decreases after a blood stop. Artificially applied potential difference between the internal and external vessel surfaces results in the changes of contractile response and vessel tone. The role of electrokinetic phenomena in regulation of contractile ability and vessel tone is discussed.
