The ionic nature of membrane potential and electrical reactions to vasodilators and vasoconstrictors of intact endothelium of rabbit aorta have been investigated. It has been shown that K+ and Na+, but not Cl- permeability form membrane resting potential. The endothelium was hyperpolarized by ACh. ATP produced the triphasic reaction of short small depolarization, hyperpolarization followed by depolarization. Both noradrenalin and serotonin evoked depolarization.
