Small bowel tissue high-energy phosphate regeneration after 7 hr of cold ischemic storage: comparison of University of Wisconsin and Eurocollins solutions.

As adenine nucleotide content has been shown to correlate with post-transplant function of livers and hearts, it was the aim of our study to investigate the regeneration of rat small bowel tissue high-energy phosphates after 7 hr of cold storage followed by incubation of everted small bowel sacs in normothermic oxygenated KHB for 1 hr. We compared the University of Wisconsin (UW) and the Eurocollins (EC) solutions. Krebs-Henseleit-bicarbonate buffer (KHB) was used to point out the effect of simple cold ischemic storage. After 7 hr of cold storage only small bowel stored in UW and EC solutions retained the capacity for almost total regeneration of ATP necessary for optimal posttransplant function, whereas in the KHB group we found only minimal regeneration. A similar pattern was found for the energy charge. These data support the superiority of UW and EC solutions over simple cold storage in KHB for preservation of small bowel.
