Effect of ischemic conditioning on blood urea nitrogen (BUN) and plasma creatinine (Creatinine) in the kidney with ischemia/reperfusion injury. In the I30 × 2 group (n = 6), BUN and Creatinine levels at 4 hours and 24 hours of reperfusion were significantly lower than those of I60 group. BUN and Creatinine levels in I15 × 4 treatment were not significantly different from I30 × 2 (n = 6) and I60 (n = 6) groups. Data are expressed as mean ± standard error mean. *, P < 0.05 vs. C group. #, P < 0.05 vs. I60 group.
