Effect of quercetin on altered vascular reactivity in aortas isolated from streptozotocin-induced diabetic rats.
The present work examined ex vivo the acute effect of quercetin on diabetic rat aortic ring reactivity in response to endothelium-dependent (acetylcholine, ACh) and endothelium-independent (sodium nitroprusside, SNP) relaxants, and to the alpha(1)-adrenergic agonist phenylephrine (PE). Responses were compared to those of aortic rings from age- and sex-matched euglycemic rats. Compared to euglyc...
متن کاملVascular Reactivity Concerning Orthosiphon stamineus Benth-Mediated Antihypertensive in Aortic Rings of Spontaneously Hypertensive Rats
Orthosiphon stamineus Benth has been traditionally used to treat hypertension. The study aimed to investigate the vascular reactivity of water extract (WOS) and water : methanolic (1 : 1) extract (WMOS) of Orthosiphon stamineus Benth and AT1 receptors blocker in the mechanisms of antihypertensive mediated by α 1-adrenergic receptor and EDNO and PGI2 releases in the SHR aortic rings. SHR (230-28...
متن کاملGadolinium increases the vascular reactivity of rat aortic rings.
Gadolinium (Gd) blocks intra- and extracellular ATP hydrolysis. We determined whether Gd affects vascular reactivity to contractile responses to phenylephrine (PHE) by blocking aortic ectonucleoside triphosphate diphosphohydrolase (E-NTPDase). Wistar rats of both sexes (260-300 g, 23 females, 7 males) were used. Experiments were performed before and after incubation of aortic rings with 3 µM Gd...
متن کاملPotassium channels and vascular reactivity in genetically hypertensive rats.
In hypertension, membrane potassium permeability and vascular reactivity are increased. This study characterizes a potassium-selective channel and contractions to barium, a potassium channel inhibitor, in vascular smooth muscle (tail artery) from spontaneously hypertensive stroke-prone rats (SHRSP) and normotensive Wistar-Kyoto (WKY) rats. Smooth muscle cells were isolated by enzymatic digestio...
متن کاملThe peripheral vascular reactivity of potassium-deficient rats.
as yet, not clarified. Data2' obtained in this laboratory indicate that the myocardial damage which may follow potassium deficiency probably does not account for the hypotensive response that occurs in either normal or hypertensive rats. An alteration in the peripheral vascular system, however, might well be involved. The following experiments therefore were undertaken in order to test the imme...
