To Protect Fatty Livers from Ischemia Reperfusion Injury: Role of Ischemic Postconditioning.

ABSTRACT:

Background

The benefit of ischemic postconditioning (IPostC) might be the throttled inflow following cold ischemia. The current study investigated advantage and mechanisms of IPostC in healthy and fatty rat livers.

Methods

Male SD rats received a high-fat diet to induce fatty livers. Isolated liver perfusion was performed after 24 h ischemia at 4 °C as well as in vivo experiments after 90 min warm ischemia. The so-called follow-up perfusions served to investigate the hypothesis that medium from IPostC experiments is less harmful. Lactate dehydrogenase (LDH), transaminases, different cytokines, and gene expressions, respectively, were measured.

Results

Fatty livers showed histologically mild inflammation and moderate to severe fat storage. IPostC reduced LDH and TXB
