Figure 1From: Disaturated-phosphatidylcholine and Surfactant protein-B turnover in human acute lung injury and in control patientsSP-B leucine and DSPC-palmitate enrichment curves in ARDS/ALI and in control patients. The 13C-leucine (top panels) and deuterium-palmitate (bottom panels) enrichment curves of SP-B and DSPC obtained from tracheal aspirates. Each symbol represents a different subject. MPE: mole percent excess; Delta (2H/1H vs smow).Back to article page
