RESUMO

The effect of prostaglandin El analogue in hepatic injury during cold ischenúa were evalueted in this study. The objective to verifY if occur attenuation in the ischemic liver damage. Thirty male rats were divided in two groups of 15 animaIs each: control, where was perfunded with University of Wisconsin solution and test group, which was perfunded with this solution added of prostaglandin El analogue (misoprostol). Biopsies were obtained immediately after perfusion and with 12, 18 and 24 hours after the perfusion. The variables analysed were tissular edema, hidropic changes, fatty changes, endothelium injury, bile duct injury, necrosis and inflammatory processo The Mann- Whitney test for non-parametric variables was used to compare the samples. In the period of 12 and 18 hours no statistical difIerences were found in biopsies. In the period of 24 hours necrosis, endothelium injury and inflammatory process were significant1y more (p <0,001) in control group. The author conc1ued that utilization of prostaglandin E 1 analogue in hepatic perfusion has a protective effect ofhepatic tissue injury during prolongated storage.
