Background: The vascular function of Angiotensin II-type-2 receptors in adults is controversial. We sought their location and function in mouse aortic rings at young and old mice. Materials and Methods: Male C57Bl mice (aged 4 and 14 months) were killed by CO2. The descending thoracic aorta was cleaned and dissected into rings. Aortic rings were mounted in Krebs’ solution at 37 °C an...
We review below published studies of endothelium-dependent vasodilation in vivo. Endothelium-dependent vasodilation has been demonstrated in conduit arteries in vivo and in the cerebral, coronary, mesenteric, and femoral vascular beds as well as in the microcirculation of the brain and the microcirculation of cremaster muscle. The available evidence, although not complete, strongly suggests tha...
We studied endothelium-dependent responses to substances released from aggregating platelets in spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY). Rings of thoracic aorta with and without endothelium were taken from adult rats and suspended for isometric tension recording in organ chambers containing modified Krebs-Ringer bicarbonate solution. Aggregating platelets ...
In the porcine coronary artery, regenerated endothelium is dysfunctional as regards the responses to endothelium-dependent agonists. The current study aimed to determine the possible involvement of histamine in such dysfunction. Pigs were treated chronically with pyrilamine (H1 receptor inhibitor, 2 mg·kg(-1)·day(-1)) with part of their coronary endothelium and allowed to regenerate for 28 days...
