Effects of magnesium sulfate administration on ischemia-reperfusion kidney in rat

This study designed to determine protective effect of magnesium sulfate on kidney function followed by ischemia-reperfusion in rat. A total 25 Wistar male rat randomly divided into 5 experimental groups (n=5). Control group: had no received medicine and gavage water for 1 week, then peritoneum opened and left kidney nephrectomy was created. The IR group: not received medicine until ischemia-reperfusion, the peritoneum opened and the renal ischemia done using clamp for 45 min, then 8 h later left nephrectomy was done. Group 3: received magnesium sulfate (25 mg/kg) for 1 week, then peritoneum opened and the renal ischemia done using clamp for 45 min, then 8 h later left nephrectomy was done. Groups 4 and 5 were similar to group 3, except rats received 50 and 100 mg/kg of magnesium sulfate, respectively. At the end of the study, tissue samples collected for histopathological evaluation and malondealdeide, Superoxide dismutase and Glutathione peroxidase levels. According to the results, the necrosis and degeneration of the nephrons was lower in magnesium sulfate treated groups compared to control grouse. Also, administration of magnesium sulfate (100 mg/kg) significantly normalized the elevated levels of malondealdeide and increased Superoxide dismutase and Glutathione peroxidase levels (P
