Efecto protector de la naringina en modelo de rata con lesión por reperfusión de isquemia renal

Objective: We aimed to research that naringin whether protects from renal ischemia/reperfusion induced renal damage in rats. Methods: Twenty-four Wistar albino female rats randomly were divided into three groups: 1) control group, in which the rats were only performed right nephrectomy; 2) a second group received right nephrectomy and left kidney ischemia (1 h) and reperfusion (24 h) group ischemia/reperfusion (I/R); 3) a third group received 50 mg/kg naringin orally once a day for two weeks before ischemia/reperfusion (I/R/N). Expression of cyclooxygenase-2 (COX-2), cytosolic phospholipase A2 (cPLA2), inducible nitric oxide synthase (iNOS), caspase-3, B-cell lymphoma-2 (Bcl-2), Bcl-2 associated x protein (Bax), serum creatinine (Cr), tumor necrosis factor α (TNF-α), interleukin 6 (IL-6) were measured by using enzyme-linked immunosorbent assay (ELISA). Results: Naringin-treated rats that performed renal ischemia/reperfusion demonstrated significant decrease in Cr, IL-6 and TNF-α levels when compared to the only renal ischemia/reperfusion performed rats. While renal ischemia/reperfusion caused a decrease of bcl-2 (1.72 ± 0.20 pg/ml) levels, while an increase of COX-2 (11882 ± 642 pg/ml), cPLA2 (2448 ± 139 pg/ml), iNOS (4331 ± 438 IU/ml), cleaved caspase-3 (7.33 ± 0.76 ng/ml) and Bax (2.33 ± 0.44 ng/ml) levels. The treatment of naringin reversed these kidney effects (7.47 ± 60.35 pg/ml; 9299 ± 327 pg/ml; 2001 ± 78 pg/ml; 3112 ± 220 IU/ml; 3.38 ± 0.54 ng/ml; 2.33 ± 0.44 ng/ml, respectively) (p
