Serum AST, ALT and LDH levels and histological examinations of hepatic injury at 6 h after reperfusion. a The increased enzymes levels in the UW preservation group were significantly suppressed in the UW + H2 preservation group (n = 3–12 per group). b Hematoxylin-eosin staining of liver tissues. The ischemia-reperfusion injury scores of the UW + H2 group were significantly lower (× 100 magnification. n = 12–18 per group). c, d Neutrophil infiltration and ED-1-positive macrophage infiltration were significantly decreased in the UW + H2 group (× 200 magnification. n = 3 for each group). e TUNEL-positive cells tended to be fewer in the UW + H2 group (× 200 magnification. n = 3 for each group); *P < 0.05
