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 کاملEndothelium-Independent Vasorelaxant Effect of Ligusticum jeholense Root and Rhizoma on Rat Thoracic Aorta.
Ligusticum jeholense has been used as the traditional medicine 'Go-Bon' (Chinese name, Gao-ben) in China and Korea. Considering the increased use of medicinal herbs to treat hypertension, in this study, we aimed to investigate the mechanisms of the vasorelaxation effect caused by L. jeholense. We tested the methanol (MeOH) extract of L. jeholense root and rhizoma for vasorelaxant effects; while...
متن کاملPurinergic endothelium-dependent and -independent contractions in rat aorta.
The role of endothelium-derived contracting factor or factors in modulating relaxations and contractions to adenine nucleotides was examined in aortas from spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto (WKY) and Wistar rats. During contractions to phenylephrine, the relaxations to ATP were impaired significantly in SHR compared with WKY aortas with endothelium. In rings tr...
متن کاملPartially Endothelium-Dependent Vasodilator Effect of Adenosine in Rat Aorta
The vasodilator effect of adenosine on the contraction induced by phenylephrine, an ar adrenergic receptor agonist, was investigated in the isolated rat aorta. We found that the effect of adenosine was greater in intact aortas than in endothelium-denuded preparations. Denuding caused a parallel shift of the dose-response curve of adenosine to the right by a factor of five in comparison with int...
