(a) Control group: Positive TNF-α reaction in a small number of macrophage cells and Kupffer cells in the periphery of the sinusoidal area, TNF-α immunostaining Bar 50 μm, (b) Carvedilol group: Positive TNF-α expression in some degenerated hepatocytes cells, endothelial cell and Kupffer cells, TNF-α immunstaining, Bar 50 μm, (c) I/R group: A significant increase in the expression of TNF-α in hepatocyte cells, endothelial and Kupffer cells, inflammatory cells in the portal and peri-portal space, TNF-α immunstaining, Bar 50 μm, (d) I/R+Carvedilol: Mild TNF-α expression in hepatocyte cells, endothelial and Kupffer cells, TNF-α immunostaining, and Bar 50 μm.
