To investigate the effect of the tadalafil in experimental renal I/R injury and to evaluate these changes with IMA (nonspesific early biomarker of ischemia), NO and MDA levels. Twenty four female Wistar rats were randomly divided into 3 groups (n=8): Group I, sham; Group II, 60 min I/R; Group III, 60 min I/R plus tadalafil. Tadalafil was administered via an orogastric tube (10 mg/kg) 24 h prior to the procedure. After ischemia of the left kidney and 1 h of reperfusion, blood samples were obtained, and the kidney was removed. Statistically significant histopathologic changes were exist between groups, with the most severe injury was determined in group II in comparison to the others (X(2)=21,803, P=0.000). Also mean serum IMA levels were higher in group II, but not statistically significant (19.83±7.81 U/ml, 22.26±7.14 U/ml and 19.82±7.77 U/ml, P=0.613). In addition, NO values were lower in I/R groups (P=0.049). There were no differences among the groups in terms of MDA. IMA may be used as a nonselective biomarker for IR injury before the occurrence of necrosis. Decreased IMA levels may indicate the nephroprotective effect of tadalafil in renal IR injury.
