Protective effects of apocynin and allopurinol on ischemia/reperfusion-induced liver injury in mice

Figure 2 Representative micrographs of in situ TUNEL staining of apoptotic cells in liver tissue after the hepatic ischemia/reperfusion procedure. A-D: The TUNEL staining assay was performed as described in the text, and the positive apoptotic cells were stained in red (× 100). A: Control; B: I/R procedure plus N.S. (6 h after starting reperfusion); C: I/R plus apocynin; D: I/R plus allopurinol. E-H: The corresponding liver sections stained with DAPI to illustrate nuclei as a cell number control.
