Evidence for normal nitric oxide—mediated vasodilator tone in conscious rats with cirrhosis
Philippe Sogni, Richard Moreau, Masaru Ohsuga, Stephane Cailmail, Frederic Oberti, Antoine Hadengue, Eric Pussard, Didier Lebrec – 1 October 1992 – Because it has been hypothesized that the hyperkinetic circulation in portal hypertension is the result of increased synthesis of nitric oxide, we compared the hemodynamic effects of nitric oxide synthesis—specific agonist (L‐arginine) and antagonist between normal and cirrhotic conscious rats. The dose‐response curves showed that L‐arginine significantly decreased arterial pressure and increased heart rate.
