Abstract
Object of our study was to characterize the effects of elevated circulating NO on hemodynamics and vascular smooth muscle cell proliferation in rats. Administration of molsidomine (10, 25, 50 mg/kg, bid p.o.) was followed by pharmacodynamic effects: elevation of plasma nitrite/nitrate levels and reduction of blood pressure (25 and 50 mg/kg, bid p.o.). Under these conditions no antiproliferative activity occurred in a model of "air dried" carotid artery injury. From these results we conclude that NO does not act as an antiproliferative agent under conditions where smooth muscle cell injury predominates.
