Beneficial effect of coenzyme Q injection on nitric oxide -related dilation of the rat aorta.

This study examined whether coenzyme Q can improve nitric oxide (NO)-dependent vasodilatation in the rat aorta after pre-incubation or intravenous administration. In initial experiments, intact isolated aortic rings were incubated with coenzyme Q or L-arginine. In further experiments, coenzyme Q was administered intravenously in anesthetized rats, then in 2h aorta was isolated.
