Protection of the liver against CCl4-induced injury by intramuscular electrotransfer of a kallistatin-encoding plasmid

Figure 3 Protective effects of kallistatin expression against carbon tetrachloride-induced liver injury in mice. HE staining was performed on paraffin embedded sections of the liver tissues. Representative sections are shown for each group. A: Control; B: Carbon tetrachloride (CCl₄); C: pLac + CCl₄; D: pKal (100 μg) + CCl₄; E: pKal (50 μg) + CCl₄; F: pKal (25 μg) + CCl₄; G: Necroinflammatory scores. ^bP < 0.01 vs control group; ^cP < 0.05, ^dP < 0.01 vs CCl₄ group.
