title: [Mineralocorticoid-induced changes of vascular reactivity to noradrenaline and angiotensin II in baboons].
abstract: In experiments on normotensive baboons of both sex the vascular reactivity on angiotensin II and noradrenaline was studied after an 18-week administration of DOCA (2 mg/b.w./week i. m.) and of common sal (5 g/day with meals). Dosage and duration of DOCA administration was chosen to prevent hypertensive haemodynamic alterations. 40 to 240 seconds after an angiotensin II injection (0.5 micrograms/kg b.w.) the pressor, especially diastolic response in both narcotized and non-narcotized animals intensified markedly. Infusion of noradrenaline (1.0 micrograms/kg b.w./min for 5 min) called forth after 120 min a significant rise in diastolic BP. Described abnormal pressor response is considered to represent a suitable model of a vascular predisposition to hypertension.
