Abstract | BACKGROUND: METHODS: 129S1/SvImj mice were subjected to thoracic aortic occlusion followed by 48 hours of reperfusion. Normal saline was administered to 25 untreated control mice and PJ34 to 21 mice before and immediately after thoracic aortic ischemia-reperfusion. Sham mice (n = 13) underwent median sternotomy alone. At 48 hours, all animals were euthanized and tissues harvested for quantitative analysis. RESULTS:
PJ34 improved intestinal (P < .05) but not hepatic mitochondrial activity following reperfusion. CD14 messenger ribonucleic acid levels in liver (P < .004), kidney (P < .003), and spinal cord (P < .03) tissue were less in PJ34-treated mice. CONCLUSIONS:
PJ34 preserved the metabolic function of intestinal but not hepatic tissue during reperfusion. PJ34 uniformly decreased the expression of an important marker of inflammatory cell activation and tissue inflammation in visceral tissue following VI. PARP inhibitors may serve as a therapeutic modality to abrogate the stress response to VI.
