Abstract

When spontaneously hypertensive rats (SHR) treated at a young age with an inhibitor of angiotensin-converting enzyme (ACE) are withdrawn from treatment, their blood pressure (BP) remains below that of untreated rats. We examined the effects of ACE inhibitor treatment and its withdrawal on angiotensin-(1-7) [Ang-(1-7)], angiotensin II (Ang II) and angiotensin I (Ang I) in plasma, kidney, adrenal, heart, aorta, brown adipose tissue, lung, and brain of male SHR and normotensive Donryu rats. Rats were administered either vehicle or perindopril (3 mg/kg/day) from 6 to 10 weeks, from 6 to 20 weeks, and from 6 to 10 weeks, followed by perindopril withdrawal from 10 to 20 weeks. Angiotensin peptides..
