Obstructive urologic diseases may cause renal injury related to intensty and duration of occlusion. In experimental studies, many pharmacological agents were used to decrease the harmful effects of obstruction on kidney. This study was designed to investigate effects of caffeic acid phenethyl ester (CAPE) on the parsial ureteral obstruction in rabbits. Twenty-one New Zealand rabbits were divided randomly into 3 groups each containing 7 animals. Group 1, 2 and 3 were defined as control (sham), partially obstructed, and partially obstructed plus CAPE treatment, respectively. All animals were sacrified at the end of 3 weeks. Malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase (SOD) and myeloperoxidase (MPO) levels were measured. In addition, kidney tissues stained with Hematoxylin-eosine were evaluated using Cleasson's histopathological criteria. MDA, NO and SOD levels were not significantly different among all groups. Mean MPO levels of groups 1, 2 and 3 were 0.22±0.07 U/g protein, 0.36±0.09 U/g protein, 0.27±0.10 U/g protein respectively. A significant increase was found in group 2 when compared to group 1(p<0.05). Kidneys of group 3 were significantly protected in terms of 2 out of 9 histopathologic criteria when compared to group 2 (p<0.05). There was significant difference between group 2 and group 3 in terms 2 out of 9 histopathologic criteria (p<0.05); injury of kidneys in group 3 was less than in group 2. MDA, NO and SOD levels which are used to detect renal injury in complete ureteral obstruction model, did not show any significant difference in partial obstruction model in our study. In the light of our biochemical and histopathologic findings, we can say that CAPE treatment has a tendency to decrease the degree of renal injury in the partial obtruction model. © 2009 OMÜ Tüm Haklari Saklidir.
