title: [Adaptation to periodic hypoxia decreases vasoconstrictor and increases vasodilator responses of resistant arteries].
abstract: Adaptation to intermittent hypoxia resulted in reduced vasoconstrictor responses of rat tail artery elicited by sympathetic nerve stimulation due to desensitization of alpha- and activation beta 2-adrenoceptors. Endothelium-dependent relaxation was enhanced under the impact of adaptation to intermittent hypoxia. These shifts may play a part in antihypertensive effect of adaptation to hypoxia which has been proved earlier.
