Background/Aims: The chronic bile duct-ligated rat is used to study hemodynamic changes in cirrhosis but suffers from total biliary obstruction and deep jaundice. The extent of reversibility of hemodynamics and histology following bile flow reconnection is controversial. We aimed to characterize the hemodynamics and histology of bile duct-ligated cirrhotic rats in which bile flow was reconnected by...
Background/Aims: The hyperdynamic circulation of cirrhosis and portal hypertension has been postulated to be due to the vasodilatory effects of nitric oxide. However, studies using pharmacological inhibitors of nitric oxide synthase have yielded conflicting results. We aimed to measure nitric oxide synthase activity in tissues from two different rat models of cirrhosis and portal hypertension.Methods:...
