    Abstract:
    INTRODUCTION: Ischemia/reperfusion injury in organ transplantation is a multifactor process that may lead to organ damage and primary graft dysfunction. Perfusion is a process which creates a possibility of graft injury. Preservation solutions are thought to diminish the ischemic injury and an appropriate choice of the solution should guarantee a better graft function and good prognosis for graft survival. The aim of the study was to examine the effect of preservation solutions University of Wisconsin (UW) and Euro-Collins (EC) on purine concentration in rat kidney. MATERIAL AND METHODS: The study was carried out on Wistar rat kidneys divided into 3 groups: kidneys perfused with 0.9% NaCl (control group), kidneys perfused with UW preservation solution, kidneys perfused with EC preservation solution. After bilateral nephrectomy the right kidney was immediately frozen in liquid nitrogen and the left kidney was placed in 4 degrees C UW, EC or 0.9% NaCl solution for 24 hours. The concentrations of purine nucleotides were determined using high-performance liquid chromatography (HPLC) method. RESULTS: The concentrations ofpurine nucleotides in renal tissue without cold ischemia did not differ significantly between rats perfused with 0.9% NaCl, UW and EC solutions. The tissue concentrations of adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), total adenine nucleotides (TAN), guanosine monophosphate (GMP) and inosine monophosphate (IMP) were significantly increased, whereas the concentrations of adenosine (Ado), inosine (Ino), guanosine (Guo), hypoxanthine (Hyp) and xanthine (Xan) were significantly lower in rats perfused with EC solution in comparison to rats perfused with 0.9% NaCl. CONCLUSIONS: Purine concentration profile in rat kidney reflects a protective influence of EC and UW solutions on high-energy nucleotides in conditions when their depletion might be harmful to graft function.
