Improved Hepatic Function in the 24-Hour Preserved Rat Liver With UW-Lactobionate Solution and SRI 63-441

The present study compares rat liver preservation for 9, 12, and 24 h in the standard Eurocollins solution with preservation for the same time periods in the new UW-Iactobionate solution. Pharmacologic manipulation with a potent plateletactivating factor antagonist, SRI 63-441, was also evaluated. After cold storage in each of the test solutions, the livers underwent 90 min of warm, oxygenated, sanguinous perfusion. A significant increase in liver weight was noted in Eurocollinsstored versus UW-Iactobionate-stored livers. After 90 min of perfusion, livers preserved in UW-lactobionate produced significantly more bile and liberated significantly less glucose and transaminases when compared with Eurocollins-stored livers. Significant augmentation of bile production was observed when donor animals were pretreated with SRI 63-441 and the livers were then stored in UW-lactobionate for 24 h. Eurocollins-stored livers demonstrated increased hepatocyte vacuolization and endothelial disruption when compared with UW-lactobionate-stored livers after 12 and 24 h of preservation. This study demonstrates the superiority of UW-lactobionate solution in liver preservation and suggests that SRI 63-441 may be beneficial in the further reduction of cold ischemic injury. © 1988, American Gastroenterological Association.
