Immunolabelling of endothelial nitric oxide synthase (eNOS) in the jejunal tissue in sham-operated animals, vehicle-treated I/R animals, and I/R animals treated with EPO five minutes before ischemia and at the onset of reperfusion. Note that mild immunolabelling of eNOS is detected in jejunal specimens from sham animals, strong immunoreactivity is detected in I/R animals and moderate immunoreactivity is detected in rHuEPO administered groups. (A) Sham: Intestinal I/R was not induced, (B) I/R: Intestinal I/R, (C) EPO + I/R: rHuEPO administered five minutes before ischemia, (D) I + EPO + R: rHuEPO administered onset of reperfusion (40×).
