dc.description.abstractResveratrol (RSV) is a natural phytoalexin with many biological effects, including antioxidant, anti- platelet, anti- atherogenic, anti- inflamatory, estrogenic properties, immunomodulation and chemoprevention. In the cardiovascular system, it has been shown to cause relaxation of vascular smooth muscle, and reports indicate that RSV induces vasodilatory effects in several vascular beds by acting in endothelium dependent and independent manners. The aim of the study was to determine the role of RSV on hypoxia induced vasoconstriction in precontracted isolated pulmonary arteries and veins. Isolated lamb pulmonary vessels were suspended in an organ bath filled with Krebs Heinseleit solution and isolated contractions were recorded continuously via an isometric transducer connected to a computerized polygraph system. The solution was aerated with room air or a gas mixture of 95% N2 + 5% CO2 (hypoxic). The oxygen concentration of the bathing medium was measured using an oxygen electrode. Serotonin (5-HT)(10-5 M) for arteries and U46619, a thromboxane analog (TXA2) for veins, were used as pre contractile agents. Our results showed that in the presence of RSV (20 ?M), hypoxia induced pulmonary vasoconstriction decreased in pulmonary veins pre contracted with U46619, but not in pulmonary arteries pre contracted with 5-HT.en_US
