Nitric Oxide Synthase and Postischemic Liver Injury

The objective of this study was to determine what roles the endothelial cell and inducible isoforms of nitric oxide synthase (eNOS, iNOS) play in ischemia and reperfusion (I/R)-induced liver injury in vivo in mice genetically deficient in each isoform of NOS. We found that 45 min of partial (70%) liver ischemia and 5 h of reperfusion induced substantial liver injury as assessed by the release of large and significant amounts of the...
