Effect of fructose-1,6-bisphosphate in the cold storage solution after 12 and 36 hours of rat liver preservation.

Fructose-1,6-bisphosphate (FBP) has been reported to have a protective effect on liver injury following ischemic/reperfusion periods because it maintains ATP levels during cold preservation. In the present study, we evaluated the effects of addition of FBP to storage solutions for cold liver preservation during 12 or 36 hours. Adult male Wistar rats were randomly divided into three experimental groups. The hepatic perfusion and preservation were performed with these solutions: UW; UW plus 10 mmol/L FBP; and FBP 10 mmol/L (FBPS) alone. The biochemical measurements of AST and ALT were performed on samples of the cold storage solution after 12- or 36-hour preservation. UW and FBPS solutions showed similar preservation grades at 12 hours. Addition of 10 mmol/L of FBP to UW solution induced liver injury and a poor preservation grade during 12 or 36 hours. UW solution was better than FBPS after 36 hours preservation. UW solution continues to offer a superior performance for liver preservation during long times; however, FBPS may be an alternative for short cold preservation times.
