ALB and acute respiratory distress syndrome: Intraperitoneal injection of LPS is an established experimental model of ALI characterized by histological changes (interstitial thickening, alveolar and interstitial neutrophil infiltration, and the presence of proteinaceous debris in the alveolar spaces), altered lung mechanics (increased elastance of the respiratory system), and effects on the alveolar-capillary barrier (increased lung wet/dry weight ratio and elevated albumin concentration in the BAL).14
