1 Thus, our main purpose for this study was to examine the effects of both big ET-1 and ET-1 to clarify the role of phosphoramidon in inhibiting the conversion of big ET-1 to ET-1, by investigating the systemic blood pressure, microvascular blood flow velocity, and diameters of arterioles and venules of the rat mesentery. phosphoramidon endothelin 1 Rattus norvegicus
2 In the second group of experiments, cumulative injections of phosphoramidon (30 mg/kg/10 min) were administered 10 min prior to the infusion of big ET-1. phosphoramidon endothelin 1 Rattus norvegicus
3 Phosphoramidon significantly suppressed the long-lasting significant pressor effect and significantly inhibited the dose-dependent increase and dose-dependent decrease in the microvascular blood flow velocity produced by big ET-1 in the rat mesenteric microcirculation. phosphoramidon endothelin 1 Rattus norvegicus
4 Moreover, phosphoramidon markedly inhibited the conversion of big ET-1 to ET-1 in the rat mesenteric microcirculation, which may suggest an inhibition of the enzyme which converts big ET-1 to ET-1. phosphoramidon endothelin 1 Rattus norvegicus
5 Moreover, phosphoramidon markedly inhibited the conversion of big ET-1 to ET-1 in the rat mesenteric microcirculation, which may suggest an inhibition of the enzyme which converts big ET-1 to ET-1. phosphoramidon endothelin 1 Rattus norvegicus
