L-Arginine Evokes Both Endothelium-Dependent and -Independent Relaxations
This study was designed to investigate the effects of L-arginine (the substrate for the formation of endothelium-derived nitric oxide) in vascular tissues. Rat aortic rings, with or without endothelium, were suspended in organ chambers for the measurement of isometric tension; they were contracted with phenylephrine (10-6 M). After a short incubation period (0.5 hour) in physiological salt solu...
متن کاملSaffron Induced Relaxation in Isolated Rat Aorta via Endothelium Dependent and Independent Mechanisms
Crocus sativus L. (saffron) is a widely used food additive for its color and taste. The hypotensive effects of saffron have been shown in previous studies. The aim of this study was to evaluate the mechanism of vasodilatory effects induced by saffron on isolated rat aorta.To study the vasodilatory effects of saffron aqueous extract (0.5, 1 and 2 mg/mL), isolated rat thoracic aorta rings were co...

متن کاملAntihypertensive therapy augments endothelium-dependent relaxations in coronary arteries of spontaneously hypertensive rats.
BACKGROUND Coronary artery disease is an important complication of hypertension. Therefore, the effects of antihypertensive therapy on the endothelial nitric oxide (NO)/L-arginine pathway and vascular smooth muscle were studied in left anterior descending coronary arteries of Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHR). Angiotensin II (AT1) receptor antagonists CGP 48369 a...
متن کاملAntihypertensive treatment normalizes decreased endothelium-dependent relaxations in rats with salt-induced hypertension.
Endothelium-dependent responses are impaired in various models of hypertension. The effects of antihypertensive treatment on endothelium-dependent relaxations were studied in Dahl salt-sensitive (DS) and Dahl salt-resistant rats (DR) on a high or low sodium diet. The rats were given either a diet containing 8% NaCl or 0.1% NaCl for 8 weeks or a diet containing 8% NaCl and a combination of reser...
