Özet
Background and Aim: This study aims to establish unilateral intermittent and unintermittent partial nephrectomy-like renal ischemia-reperfusion (I-R) model in rats and to compare the results with biochemical findings. Material and Methods: The study was conducted on 24 adult 8-week-old male Wistar-Albino rats, each weighing s200-250 g. The rats were divided into three groups. In the Sham group (n = 8), the kidney was surgically exposed and closed. We designed experimental I-R models in the second group (n = 8, a total of 30-min ischemia model in the manner of 3 intermittent sets 8 minutes clamping and 2 min unclamping) and in the third group (n = 8, one session of 30-min unintermittent ischemia). In postoperative day 1, the rats were sacrificed, and the effects of I-R models on the renal tissue were comparatively assessed by evaluating serum Neutrophil Gelatinase-Associated Lipocalin (NGAL), serum kidney injury molecule-1 (KIM-1), urinary NGAL, urinary KIM-1, and serum creatinine levels. Results: Urinary NGAL and KIM-1 levels were significantly higher in the continuous ischemia group when compared to those in the sham and intermittent ischemia groups (P < 0.05). In the intermittent ischemia group, urinary NGAL and urinary KIM-1 levels were significantly higher than those in the sham group (P < 0.05). Although the results of serum NGAL, serum KIM-1, and serum creatinine levels seemed to be in parallel to the results of urinary markers, no statistically significant difference was found. Conclusion: Renal injury was significantly less in the intermittent I-R model when compared to that in the unintermittent I-R model in our experimental rat study.
