Enhanced cyclooxygenase‐1 expression within the superior mesenteric artery of portal hypertensive rats: Role in the hyperdynamic circulation
Ming‐Chih Hou, Paul A. Cahill, Shuangmin Zhang, Yi‐Ning Wang, Richard J. Hendrickson, Eileen M. Redmond, James V. Sitzmann – 30 December 2003 – Portal hypertension (PHT) is characterized by splanchnic hyperemia due to enhanced production of vasodilator substances. Enhanced vasodilation and increased splanchnic blood flow contribute to the elevated portal pressure characteristic of PHT. The aim of this study was to determine whether cyclooxygenase (Cox) expression is altered in PHT vessels and whether chronic inhibition of this enzyme impacts on splanchnic blood flow in PHT.
