title: The renin-angiotensin system, dietary salt, and increased sensitivity to noradrenaline in mesenteric vasculature preparations from renal/salt hypertensive rats.
abstract: Exogenous angiotensin II causes noradrenaline supersensitivity in rat mesenteric vasculature preparations. The noradrenaline supersensitivity of tissues from renal/salt hypertensive rats, with low plasma renin activity, is not caused by endogenous angiotensin II since it was unaffected by Sar1 Ileu8 angiotensin II. Dietary salt-loading caused a small increase in noradrenaline sensitivity.
