Core Tip

Core tip: Ischemic preconditioning has been shown to reduce ischemia/reperfusion injury (IRI) in the liver. NO has been shown to be important in the preconditioning process as well as in IRI. This study shows that ischemic preconditioning (IPC) but not remote ischemic preconditioning (R-IPC) reduces inducible nitric oxide synthase and interleukin 1 receptor transcription during early reperfusion. As it has been shown that IPC protects the liver more than R-IPC, this reduction in inflammatory activation may be important. In addition, this study shows that nitrite and nitrate are consumed in the liver during ischemia, unlike the levels in peripheral blood.
