Quantification of surfactant phospholipids in the dog lung.
We quantified total phospholipid (PL), total and disaturated phosphatidylcholine (PC and DSPC), phosphatidylglycerol (PG), and total protein in alveolar washings and lung tissue in 22 dog lungs. Quantitative recovery of alveolar material and assessment of its possible contamination by blood lipids were important determinants of methodology. To remove blood, the vessels of half the lungs were pe...
متن کاملQuantification of surfactant pool sizes in rabbit lung during perinatal development.
Methods are presented for the quantitative isolation of surfactants from fetal and newborn rabbit alveolar lavage returns and post-lavaged lung tissue homogenates. The phospholipid content of both fractions progressively increased between 27 days gestation and term (31 days). The tissue-stored fraction increased approximately 16-fold (from 0.48 +/- 0.13 to 7.83 +/- 0.86 mg/g dry lung) and the a...

متن کاملSurfactant sputtering
Sputter erosion of materials is among the most important techniques for fabricating advanced thin film coatings. Sputter processes are also of considerable relevance for surface polishing down to an atomic scale, nanostructuring of surfaces as dot and ripple patterns and micromachining of materials using focused ion beams or reactive ion etching. We present a new, versatile sputter technique ut...
متن کاملSurfactant, mechanical
At present, exogenous surfactant replacement therapy and mechanical ventilation (MV) remain the ‘Standard of Care’ while treating such infants. However, this requires endotracheal intubation – an invasive procedure associated with complications. Moreover, the skills required to intubate very small babies are not universally available and may vary among the healthcare professionals even in devel...
