In this experimental study, we evaluated the effect of trimetazidine (TMZ) on renal ischemia-reperfusion (IR) injury in Sprague-Dawley rats. Renal IR was achieved by a 75-min clamping of the left renal pedicle and subsequent 24 h reperfusion, after right nephrectomy was performed. The rats were randomly divided into three groups: group 1 (sham-operated: no IR injury), group 2 (ischemic control: saline treatment), and group 3 (3 mg/kg TMZ before ischemia). After 24 h of reperfusion, blood samples and renal tissue samples were taken to measure the levels of creatinine, tissue malondialdehyde (MDA), and glutathione peroxidase (GSH-Px) activity. Histopathological changes were evaluated. In addition, the 7-day survival rates in each group were evaluated. We found significant increases in the levels of creatinine and tissue MDA, severe acute tubular necrosis, and a significant decrease in the activity of the GSH-Px in group 2. There were significant decreases in the levels of creatinine and tissue MDA, mild acute tubular necrosis, and a significant increase in activity of the GSH-Px in group 3 when compared with the control group (p <0.05). Statistically significant differences (p <0.05) in survival were noted between the ischemic control and sham-operated and TMZ groups. We have concluded that TMZ is able to protect the kidney from warm IR injury.

This study was performed to investigate the protective effect of combined use of Vitamins E and C on colistin-induced tubular damage in rat. Animals were treated with sterile saline, colistin methanesulfonate (CMS), CMS + Vitamin E + Vitamin C, and Vitamin E + vitamin C, respectively, for seven days. Thereafter, animals were sacrificed and the urine N-acetyl-b-D-glucosaminidase (NAG) and gamma-glutamyl transferase (GGT) levels, plasma level of creatinine (Cr), vitamin E and vitamin C, and renal tissue levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), as well as renal histology were performed. CMS induced acute tubular necrosis, increased the NAG, GGT, and MDA levels, and reduced the Vitamin E, Vitamin C, SOD, CAT, and GPx activities. Co-treatment with vitamins E and C restored all biochemical parameters cited above and improved the histopathological damage. Tubular damage induced by colistin is at least partly due to oxidative stress. Nephroprotective effect of Vitamins E and C is partially mediated through its antioxidant properties, and the higher protection by the combination of these vitamins is related to its synergistic effects.
