Photomicrographs of apoptotic cells in the jejunal tissue stained by the TUNEL method 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. The dark brown dots correspond to representative TUNEL-positive nuclei. (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 (200×).
