Long-term HRSS treatment prevented delayed injury after renal I/R injury. In the STT group, delayed renal injury, such as renal edema, epithelial cell loss and increased red blood cells in the renal tubule, occurred once the treatment stopped and were suppressed by long-term HRSS treatment. Histological changes observed after renal I/R injury included tubular cell necrosis, cytoplasmic vacuole formation, hemorrhage and tubular dilatation. Injury scores are expressed as mean ± SD. Semi-quantitative injury scores ranged from 0 to 5 (0: normal kidney; 1: 0–10% injury; 2: 11–25% injury; 3: 26–45% injury; 4: 46–75% injury; 5: 76–100% injury).
