title: Cardiovascular reactivity to noradrenaline and angiotensin in normotensive, hypertensive and 6-hydroxydopamine treated rats.
abstract: Blood pressure responses to intravenous noradrenaline and angiotensin in the pithed rat preparations from normotensive, chronically hypertensive and 6-hydroxydopamine (6-OHDA) treated groups were found to follow different patterns. 6-OHDA treated rats were very sensitive to the effects of the two pressor agents and repeated administration of the two drugs invariably led to cardiovascular collapse.
