Angiotensin II AT1 receptor blockade prevents gastric ulcers during cold-restraint stress.

Abstract

Cold-restraint stress reduces gastric blood flow and produces acute gastric ulcers. We studied the role of Angiotensin II (Ang II) on gastric blood flow and gastric ulceration during stress. Spontaneously hypertensive rats, a stress-sensitive strain, were pretreated for 14 days with the AT(1) receptor antagonist candesartan before cold-restraint stress. AT… (More)
