Fructose diphosphate attenuates the acetaminophen-induced liver injury in the rat evidence for involvement of nitric oxide.

We have previously shown that fructose-1,6-diphosphate (FDP) stimulates the synthesis of nitric oxide probably by stimulating the hepatic inducible nitric oxide synthase (iNOS). The aim of the present study was to evaluate the hepatoprotective role of FDP in acetaminophen-induced liver injury and whether this hepatoprotective effect is mediated by nitric oxide. Liver injury was induced in adult Sprague-Dawley rats by the administration of acetaminophen (1.
