      Abstract

      The effect of the specific alpha1-blocker prazosin (Adversuten) on the microcirculation in the region of the terminal ileum was examined on 10 rabbits. Before and after injection of prazosin into the superior mesenteric artery an isotope-clearance of a 133Xe-solution, applied into the intestinal wall, was performed. Because of the systemic blood pressure decreasing effect of prazosin the circulation of the examined part of the intestine was reduced in spite of the intended vasodilation of the intestinal vessels. The therapeutic applicability of alpha-blockers for intestinal diseases of vascular genesis remains questionable.
