[The adrenergic mechanisms of intravascular pressure stabilization when the volume velocity of the blood flow is altered].
Experiments in cats revealed that the vasoconstrictor effect of norepinephrine and propranolol involved an increase in extensibility of vessels. Preliminary beta-adrenoceptor blockade decreased both the vessels' extensibility and their ability to resist against growing pressure in acceleration of the blood flow volume velocity. The role of adrenergic systems in intravascular pressure stabilisation in acceleration of the blood flow volume velocity is emphasized. pressure stabilisation in acceleration of the blood flow volume velocity is emphasized.
