Abstract
Release of endothelin-1 (ET-1) from the mesenteric arteries of Wistar rats with streptozotocin-induced diabetes (STZ-DM) rats and nondiabetic rats was measured by a specific enzyme immunoassay following purification using an immunoaffinity column. The mesenteric arteries from STZ-DM rats released a significantly higher amount of ET-1 as compared to control rats (35.8 +/- 2.8 vs 14.9 +/- 2.0 pg/1hr, p less than 0.05). The plasma level of ET-1 in STZ-DM rats was also elevated to a significant extent as compared to controls (5.1 +/- 0.4 vs 3.0 +/- 0.4 pg/ml, p less than 0.05). The systolic blood pressure of STZ-DM rats was significantly higher than of the controls (p less than 0.05). The increased level of plasma ET-1 as well as its release from the mesenteric artery of STZ-DM rats may suggest its release following damage to the endothelium caused by diabetes and/or by associated changes in blood pressure.Entities:
