Figure 5 Assessment of cleaved caspase-3 expression in the liver parenchyma: The sham group had no cleaved caspase-3-positive cells in the hepatic parenchyma. In the ischemia-reperfusion (IR) group, cleaved caspase-3 was expressed in the cytoplasm of the hepatocytes (black arrows) around the necrotic area (*) in the pericentral zone (zone 3). The IR+milrinone group had fewer cleaved caspase 3-positive hepatocytes (A). The IR group had significantly more cleaved caspase-3-positive hepatocytes in zone 3 than in the periportal zone (zone 1). The IR+milrinone group had significantly fewer cleaved caspase-3-positive hepatocytes in zone 3 than did the IR group (B). * Significantly different (P<0.05) from zone 1 of the IR group. # Significantly different (P<0.05) from the IR group of the same zone.
