Effects of butein on renal ischemia/reperfusion injury: An experimental study.

Abstract

Renal ischemia/reperfusion (I/R) injury is a common cause of acute kidney injury. The aim of this study was to investigate the effect of butein on renal I/R injury. Twenty-seven rats were randomly allocated to three groups (n = 9): a sham group, a renal I/Runtreated (control) group, and a renal I/R-butein group. The sham group underwent only opening and closing of the peritoneum. In the control group, an experimental I/R model was created and 1 cc isotonic saline was applied to the peritoneum. In the butein group, the experimental I/R model was created and 1 mg/kg butein was administered intraperitoneally 15 minutes before the beginning of ischemia. The left kidneys of the rats were histopathologically examined for tissue damage caused by I/R. Histopathological examination of the tissue damage revealed that all kidneys in the sham group were normal. By contrast, 2 in the control group (22.2%) had small focal damaged areas, 1 (11.1%) had < 10% cortical damage, 5 (55.6%) had 10-25% cortical damage, and 1 (11.1%) had 25-75% cortical damage. The butein group had 1 (11.1%) normal kidney, 2 (22.2%) with small focal damaged areas, 4 (44.4%) with < 10% cortical damage, and 2 (22.2%) with 10-25% cortical damage. Tissue damage was significantly lower in the sham group than in the control and butein groups (p < 0.01). No statistically significant differences were observed in the histopathology of the control and butein groups (p > 0.05). Intraperitoneal administration of butein had no significant effect on renal tissue injury.
