In this model of porcine GAS-induced septic shock, which was not associated with enhanced NO production, infusion of the NOS inhibitor AE-ITU prolonged survival, prevented hypotension, and improved cardiac contractility, organ perfusion, and tissue oxygenation. These beneficial effects of AE-ITU might be a result of the combined effect of ROS scavenging and modulation of local NO production, thus improving the balance of vasodilator and vasoconstrictor forces and reducing oxidative stress.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
