Effects of angiotensin subtype 1 and subtype 2 receptor antagonists in normotensive versus hypertensive rats.
The purpose of this study was to examine in vivo the importance of angiotensin subtype 1 (AT1) versus subtype 2 (AT2) receptors in spontaneously hypertensive (hypertensive) versus normotensive Wistar-Kyoto (control) rats. Intravenous infusions of DuP 753, a selective AT1 receptor antagonist, abolished the pressor responses to intravenous infusions of angiotensin II in both strains, and the pote...
متن کاملInfluence of Angiotensin II Subtype 2 Receptor (AT2R) Antagonist, PD123319, on Cardiovascular Remodelling of Aged Spontaneously Hypertensive Rats during Chronic Angiotensin II Subtype 1 Receptor (AT1R) Blockade
Cardiac AT(2)R expression is upregulated in the normal process of aging. In this study we determined the contribution of AT(2)R to chronic antihypertensive and remodelling effects of AT(1)R blockade in aged hypertensive rats. Adult (20 weeks) and senescent (20 months) spontaneously hypertensive rats (SHRs) were treated with either the AT(1)R antagonist, candesartan cilexetil (2 mg/kg/day), the ...
متن کاملAngiotensin-converting enzyme and angiotensin II receptor subtype 1 inhibitors restitute hypertensive internal anal sphincter in the spontaneously hypertensive rats.
The present study determined the effects of the angiotensin-converting enzyme (ACE) inhibitor captopril and angiotensin II receptor subtype 1 (AT1-R) antagonist losartan on the internal anal sphincter pressures (IASP) in spontaneously hypertensive rats (SHR) versus normotensive Wistar-Kyoto rats (WKY). The SHR had significantly higher IASP (21.7 +/- 0.8 mm Hg) than the WKY (14.7 +/- 0.9 mm Hg),...
متن کاملAntiinflammatory effects of angiotensin II subtype 1 receptor blockade in hypertensive patients with microinflammation.
BACKGROUND Experimental studies revealed proinflammatory properties of angiotensin II. We evaluated antiinflammatory effects of the angiotensin II subtype 1 receptor antagonist olmesartan medoxomil alone and in cotherapy with the HMG-CoA reductase inhibitor pravastatin in patients with essential hypertension and microinflammation. METHODS AND RESULTS We measured a panel of vascular inflammati...
متن کاملHypothalamic angiotensin receptor subtypes in normotensive and hypertensive rats.
The binding of125I-labeled [Sar1,Ile8]angiotensin II to the hypothalamic membranes of the normotensive Wistar-Kyoto rat (WKY) and the spontaneously hypertensive rat (SHR) was studied. Displacement experiments with four centrally active angiotensins, losartan, and PD-123319 confirm the known existence of angiotensin AT1 and AT2 receptors in the rat hypothalamus. The values of the inhibitory cons...
