Extravascular lung water assessed by transpulmonary single thermodilution and postmortem gravimetry in sheep
(Journal article; Tidsskriftartikkel; Peer reviewed, 2004-10-19)
Introduction:
Acute lung injury is associated with accumulation of extravascular lung water (EVLW). The aim of the present study was to compare two methods for quantification of EVLW: transpulmonary single thermodilution (EVLWST) and postmortem gravimetric (EVLWG).
Methods:
Eighteen instrumented and awake sheep were randomly assigned to one of three groups. All groups received Ringer's ...
Tezosentan-induced attenuation of lung injury in endotoxemic sheep is associated with reduced activation of protein kinase C
(Journal article; Tidsskriftartikkel; Peer reviewed, 2005-03-04)
Introduction:
Studies in vitro reveal that endothelin-1 (ET-1) activates the α isoform of protein kinase C (PKC-α) in cultures of endothelial cells, thereby deranging cellular integrity. Sepsis and endotoxemia are associated with increased plasma concentrations of ET-1 that induce acute lung injury (ALI). We recently reported that non-selective ET-1 receptor blockade attenuates ALI in sheep by ...
Tezosentan reduces the microvascular filtration coefficient in isolated lungs from rats subjected to cecum ligation and puncture
(Journal article; Tidsskriftartikkel; Peer reviewed, 2005-10-18)
Introduction:
We recently demonstrated that the non-selective endothelin-1 (ET-1) receptor blocker tezosentan antagonizes ovine acute lung injury (ALI) following infusion of endotoxin or ET-1 by reducing the enhanced lung microvascular pressure, although we could not exclude the possibility of a simultaneous decline in microvascular permeability. In the present study, our aim was to find out if ...
Inhaled aerosolised recombinant human activated protein C ameliorates endotoxin-induced lung injury in anaesthetised sheep
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-04-08)
Introduction We recently demonstrated that intravenously
infused recombinant human activated protein C (APC)
attenuates ovine lipopolysaccharide (LPS)-induced lung injury.
In this study, our aim was to find out whether treatment with
inhaled aerosolised APC (inhAPC) prevents formation of
increased lung densities and oedema and derangement of
oxygenation during exposure to LPS.

Recombinant human activated protein C attenuates endotoxin-induced lung injury in awake sheep
(Journal article; Tidsskriftartikkel; Peer reviewed, 2008-08-15)
Introduction: Acute lung injury often complicates severe sepsis.
In Gram-negative sepsis, bacterial endotoxin activates both
coagulation and inflammation. Enhanced lung vascular
pressures and permeability, increased extravascular lung water
content and deteriorated gas exchange characterize ovine
endotoxin-induced lung injury, a frequently used model of acute
lung injury. Recombinant human ...
Recombinant human activated protein C ameliorates oleic acid-induced lung injury in awake sheep
(Journal article; Tidsskriftartikkel; Peer reviewed, 2008-11-20)
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 ...
