Ischemia leads to mild acute tubular injury. Histologic changes were assessed in the left kidneys 10 minutes after either 32 or 60 minutes of left unilateral ischemia AKI (UiAKI) or sham procedure. (A) Representative images of PAS (×200 magnification) staining and (B) acute tubular necrosis scoring demonstrate tubular injury in the ischemic kidneys was mild and without significant difference between ischemia times. n=5; P<0.05. * indicates a statistical difference between the UiAKI group and its paired sham control (e.g., UiAKI³² versus sham³²); ** indicates a statistical difference between the 32-minute and 60-minute ischemia times.
