Open Access Abstract Introduction Acute lung injury ALI may arise both after sepsis and non-septic inflammatory conditions and is often associated with the release of fatty acids including oleic acid OA . Infusion of OA has been used extensively to mimic ALI. Recent research has revealed that intravenously administered recombinant human activated protein C rhAPC is able to counteract ALI. Our aim was to find out whether rhAPC dampens OA-induced ALI in sheep. Methods Twenty-two yearling sheep underwent instrumentation. After 2 days of recovery animals were randomly assigned to one of three groups a an OA rhAPC group n 8 receiving OA mL kg infused over the course of 30 minutes in parallel with an intravenous infusion of rhAPC 24 mg kg per hour over the course of 2 hours b an OA group n 8 receiving OA as above or c a sham-operated group n 6 . After 2 hours sheep were .
