Portal hypertension (PHT) is characterized by splanchnic hyperemia due to a reduction in mesenteric vascular resistance. The reasons for the decreased resistance include an increased responsiveness to a vasodilator substance. Because the activation of an inhibitory guanine nucleotide regulatory (Gi) protein can result in endothelium-dependent relaxation, we tested the hypothesis that exaggerated Gi-protein...
The hemodynamic effects of long-term administration of octreotide in portal hypertension has not been established. In addition, whether long-term octreotide treatment prevents the development of portosystemic shunts has not yet been evaluated. Hence, the current study was undertaken to evaluate the effects of long-term administration of octreotide in rats with portal vein stenosis. Immediately after...
