Haematological and biochemical reference intervals in healthy Ragdoll cats.

Objectives: Breed-specific reference intervals (RIs) may be necessary to avoid misinterpretation of laboratory results. The main aim of this study was to establish haematobiochemical RIs for Ragdoll cats.

Methods: Forty-two clinically healthy adult (0.

Mechanical ventilation and volutrauma: study in vivo of a healthy pig model.

Mechanical ventilation is essential in intensive care units. However, it may itself induce lung injury. Current studies are based on rodents, using exceptionally large tidal volumes for very short periods, often after a "priming" pulmonary insult.

Activated protein C protection from lung inflammation in endotoxin-induced injury.

We studied the protection of recombinant human activated protein C (rhAPC) in endotoxin-induced lung inflammation and injury and whether this effect is correlated with modulation of lung matrix metalloproteinase (MMP) activity. We randomly assigned 12 Large White pigs to receive intravenous Escher-ichia coli lipopolysaccharide (LPS; 40 mu g/kg/hr), rhAPC (24 mu g/ kg/hr), or both. We monitored respiratory mechanics and function, cell counts, and cytokine concentrations in bron-choalveolar lavage fluid (BALF).
