    Abstract:
    During ischemia-reperfusion, free oxygen radicals which directly affect renal cells may cause delayed graft function. We investigated whether there was a difference regarding antioxidant enzyme content between use of Ringer's lactate (RL) versus University of Wisconsin (UW) perfusion solutions in kidney transplantation. Ischemia was achieved by clamping the renal pedicle for 20 minutes followed by perfusion with either solution for 20 minutes and reperfusion for another 20 minutes. A parenchymal biopsy was taken before and after the ischemia, perfusion, and reperfusion (IPR) process. The levels of superoxide dismutase (SOD), glutathione peroxidase (GPx), and malondialdehyde (MDA) were investigated in the biopsy specimens. We used paired t tests within groups and t tests for comparisons between groups. The results were expressed as mean values +/- SEM with P < .05 accepted as statistically significant. After IPR, SOD, GPx, and MDA were decreased in all groups: only GPx (P = .001) and MDA (P = .04) for the RL group and SOD (P = .001) and MDA (P = .05) for the UW group were statistically significant. In the control group, we did not observe any difference (P > .05). Comparisons between groups did not reveal differences (P > .05). In our study, no difference was observed between RL and UW regarding their effects on antioxidant enzymes following renal I/R injury in pigs. More investigations are needed to evaluate graft function in this setting.
