The aim was to determine whether uptake of 5-hydroxytryptamine (5-HT) by the 5-HT transporter (SERT) modulates contractile responses to 5-HT in rat pulmonary arteries and whether this modulation is altered by exposure of rats to chronic hypoxia (10% oxygen; 8 h/day; 5 days). The effects of the SERT inhibitor, citalopram (100 nM), on contractions to 5-HT(More)
ODQ, (1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one, an inhibitor of soluble guanylate cyclase) inhibits vasorelaxant responses to nitric oxide (NO)-donor drugs, but the extent of the inhibition varies depending on the NO donor studied. The purpose of this study was to test the hypothesis that these variations in the effects of ODQ reflect differences in the(More)
