    Abstract:
    Effects of Lipo-PGE1, prostaglandin E1 incorporated in lipid microspheres on liver injury caused by ischemia reperfusion were investigated. Lipo-PGE1 (10 micrograms/kg or 3 micrograms/kg) or vehicle was gradually injected twice via portal vein 5 min prior to induction of ischemia and reperfusion. Rats died within 2 d after liver ischemia of 90 min from the group receiving injection of vehicle alone. Lipo-PGE1 had its most profound effect on the survival of animals subjected to liver ischemia followed by reperfusion when given in two doses, one prior to ischemia, and another prior to reperfusion. Lipo-PGE1 markedly suppressed both the increases in plasma PCOOH (phosphatidyl-choline hydroperoxide) levels and the leakage of GOT, GPT, and LDH from the liver during the ischemia reperfusion. These findings suggest that Lipo-PGE1 may have therapeutic applications in treatment of hepatic injury.
