[The effect of adaptation to a course of stress-inducing electrostimulation on the reactivity of an isolated resistive artery].
Repeated stress adaptation made with a course of electrostimulation was found to result in changes in the responsiveness of the rat isolated tail artery taken from adapted animals. These changes appeared as decreased vasoconstrictive responses to norepinephrine and significantly higher endothelium-dependent vasodilation induced by acetylcholine and the beta-agonist isoproterenol. The regulatory shift occurred towards vasodilation of the resistive artery makes the studies of the impact of stress adaptation on blood pressures in hypertension promising.
