Abstract

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 post-transplant 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.
