Saffron 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 کاملA novel mechanism of vascular relaxation induced by sodium nitroprusside in the isolated rat aorta.
Sodium nitroprusside (SNP) is an endothelium-independent relaxant agent and its effect is attributed to its direct action on the vascular smooth muscle (VSM). Endothelium modulates the vascular tone through the release of vasoactive agents, such as NO. The aim of this study was to investigate the contribution of the endothelium on SNP vasorelaxation, NO release and Ca2+ mobilization. Vascular r...

متن کاملEndothelium-dependent relaxation in aorta of BB rat.
The study was undertaken to determine whether the phenomenon of endothelium-dependent relaxation was impaired in the spontaneously diabetic BB Wistar rat. Endothelium-dependent relaxation in the aorta of overtly diabetic animals was compared with that in nondiabetic BB rats. The relaxative responses were elicited in vitro to acetylcholine (-8.0 to -5.5 log M) and histamine (-7.0 to -3.0 log M) ...
متن کاملUridine adenosine tetraphosphate induces contraction and relaxation in rat aorta.
Uridine adenosine tetraphosphate (Up(4)A) has been recently reported as an endothelium-derived vasoconstrictor and plasma levels of this dinucleotide are increased in juvenile hypertensive subjects. This study aimed to evaluate the vascular actions of Up(4)A, typify the putative purinergic receptors that might mediate these effects and characterize the intracellular signaling pathways that may ...
