Hypothesis
Does recombinant human activated protein C (rhAPC) antagonize endotoxin-induced lung injury in sheep?
Conclusion
In awake sheep, rhAPC alleviates endotoxin-induced lung injury by improving oxygenation, coagulation, and inflammation.
Supporting Evidence
- Infusion of endotoxin caused lung injury, which was reduced by rhAPC.
- rhAPC improved oxygenation and reduced inflammatory markers.
- Histological examination showed less lung injury in rhAPC-treated sheep.
Takeaway
This study shows that a special protein can help sheep breathe better when they are sick from bacteria.
Methodology
Sheep were divided into groups receiving either endotoxin alone, rhAPC alone, or both, and various lung function and blood parameters were measured.
Potential Biases
Use of human kits may introduce bias due to species differences.
Limitations
Some coagulation and inflammatory markers had missing values, and human kits were used for sheep samples.
Participant Demographics
Twenty-five yearling sheep weighing approximately 44.1 kg.
