Abstract

The aim of this study is to explore the hepatoprotective effect of intraportal prostaglandin E1 (PGE1) on liver ischemia reperfusion (IR) injury using an extrahepatic cholestatic model, observing oxidative stress markers, proinflammatory factors, apoptotic marker proteins, and an adhesion molecule. The extrahepatic cholestatic model was induced by common bile duct ligation. After seven days, rats were subjected to ischemia by Pringle maneuver for 15 min, followed by 1, 6, or 24 h of reperfusion. Prostaglandin E1 (PGE group) or normal saline (NS group) was continuously infused from 15 min before liver ischemia to 1 h after reperfusion. After reperfusion, histopathological evaluation of the liver was performed, as were measurements of bilirubin, biochemical enzymes, oxidative stress markers (GSH and MDA), proinflammatory factors (MPO, TNF-α, and IL-1β), apoptotic marker proteins (Bcl-2 and Bax), and the adhesion molecule (ICAM-1). PGE1 pretreatment attenuated IR injury in extrahepatic cholestatic liver probably by suppressing MDA, MPO, TNF-α, IL-1β, ICAM-1, and Bax levels and improving GSH and Bcl-2 levels. In conclusion, PGE1 protects extrahepatic cholestatic liver from IR injury by improving hepatic microcirculation and reducing oxidative stress damage, intrahepatic neutrophil infiltration, and hepatocyte apoptosis.
