Reduction of hepatocellular apoptosis after liver IR through LPS preconditioning.

<p>(A) Liver apoptosis by TUNEL stainning: (a) sham group; (b) IR group and (c) LPS PC+IR group. (B) Apoptotic cells were quantified in six high-power fields (400×), and expressed as percentages of apoptotic cells among total cells. Mean±SD, **P<0.001 versus sham group; ^#P<0.05 versus IR group. (C) Caspase-3 activity, Mean±SD, **P<0.001 versus sham group; ^##P<0.001 versus IR group.
