摘要：

1. isolated aortic segments from transgenic rats for the mouse renin gene Ren-2 were more sensitive than those from control Sprague-Dawley ones to the vasoconstrictions induced by angiotensin II and to the potentiation of norepinephrine contractions by this peptide. 2. In transgenic, but not in control aorta, pretreatment with angiotensinogen potentiated norepinephrine-induced vasoconstrictions, this effect being abolished by captopril. 3. These results suggest that in the aorta of transgenic rats there is a higher functional tissue renin-angiotensin system that potentiates the vascular reactivity to norepinephrine.
