Fig. 3From: The endogenous capacity to produce proinflammatory mediators by the ex vivo human perfused lungImpact of exogenous blood on biomarker change after 4 h of ex vivo lung perfusion. a Comparison of change in perfusate biomarker levels after 4 h of ex vivo perfusion in control lungs in the presence (n = 21) or in the absence (n = 17) of exogenous blood, and in IV S. pneumoniae exposed lungs in the presence (n = 19) or in the absence (n = 22) of exogenous blood. b Comparison of change in airspace biomarker levels after 4 h of ex vivo perfusion in control lungs in the presence (n = 16) or in the absence (n = 13) of exogenous blood, and in IV S. pneumoniae-exposed lungs in the presence (n = 13) or in the absence (n = 14) of exogenous bloodBack to article page
