title: [Transmembrane potential and electrogenicity of thrombocyte Na, K-ATPase in different forms of hypertension in rats].
abstract: The fluorescent dye 3,3'-dipropylthiadicarbocyanine iodide, dis-C3-(5), was used to study the membrane potential of platelets in rats with renal, DOCA-induced and spontaneous hypertension. The magnitude of the transmembrane potential in platelets combines the activity of electrogenic Na, K-ATPase and the rate of ion diffusion across the plasma membrane. The basal potential is 12 = 14 mB as lowered only in spontaneously hypertensive rats. The decrease of the basal potential is made for electrogenicity of platelet Na, K-ATPase in spontaneously hypertensive rats.
