Core Tip

Core tip: In cirrhosis, extrahepatic vascular hypocontractility leads to splanchnic vasodilation and decreased splanchnic vascular resistance. In this study, clear gender differences were observed in mesenteric vascular reactivity in carbon tetrachloride-induced cirrhotic and portal hypertensive rats. Conservation of estrogen can retain the sensitivity of mesenteric arterioles to vasoconstrictors and has a protective effect on splanchnic vascular function in portal hypertension.
