Progressing pathohistological injury with increasing ischemia time after reperfusion for 24 h and 5 weeks. a: After 24 h reperfusion any treatment group revealed histological injury, whereas reperfusion for 5 weeks allowed histological healing according to the tubular injury score only in the treatment group of ischemia for 15 min. Unilateral ischemic injury for 25 min, 35 min and 45 min induced persistent (5 weeks) histopathological lesions. b: Representative images of PAS stained sections (50x magnification) of renal cortices of kidneys undergone unilateral ischemia for 15 min, 25 min, 35 min and 45 min and reperfusion for 24 h and 5 weeks. Displayed are means with s.e.m. *P < 0.05 versus control
