Effect of IPoC on the mRNA expression levels of (A) ICAM-1, (B) IL-6 and (C) TNF-α in the kidney after 45 min of ischemia, followed by 24, 72 and 120 h of reperfusion. The mRNA expression levels were standardized against β-actin. The data are presented as the mean ± standard error of mean. *P<0.05, vs. sham; #P<0.05, vs. I/R at 24 h; •P<0.05, vs. I/R at 72 h; P<0.05, vs. I/R at 120 h. TNF-α, tumor necrosis factor-α; IL-6, interleukin-6; ICAM-1, intercellular adhesion molecule-1; sham, sham-operated; I/R, ischemia and reperfusion; IPoC, ischemic postconditioning.
