Core Tip

Core tip: Endothelial dysfunction (ED) is a key and early relentless event in patients suffering from gastrointestinal bleeding in cirrhosis and involves in response to both vasoactive and vasoconstrictor substances. The one such vasoactive molecule, nitric oxide (NO) plays a prime role in maintaining normal hepatic vascular function and if there any defect in NO availability leads to ED and portal hypertension (PHT) could be of great utility in preventing and curing complications of PHT.
