50 Years Ago in THE JOURNAL OF PEDIATRICS Surface Properties and Lipids from Lungs of Infants with Hyaline Membrane Disease Adam FH, Fujiwara T, Emmanouilides G, Scudder A. J Pediatr 1965;66:357-46
ollowing the seminal report from Avery and Mead in 19591 that saline extracts of lungs of infants who had died of respiratory distress syndrome (RDS) had high surface tensions, other investigators explored in more detail surfactant and its relationship to RDS. In this 1965 study, Adams et al measured surfactant lipid amounts, lipid compositions, and surface tensions for saline and organic solvent extracts of lungs of preterm infants. In general, samples from infants with very low birth weights had less lipids and high surface tensions. The lecithin (phosphatidylcholine) content also was low. However, two infants with RDS had high amounts of lipids with good surface properties. The authors described the cases: one with 4½ weeks rupture of membranes (probably infected) and the other with intraventricular hemorrhage. They discuss the possibility that other substances lost in the extraction procedures could interfere with surfactant function, a now well-known phenomenon that was not appreciated at the time. This article is an early report that contributed to an understanding of surfactant deficiency. Dr Adams published 48 reports in The Journal from 1946 to 1975, many on fetal lung development. Dr Fujiwara was a visiting scientist with Dr Adams at University of California, Los Angeles in 1965, and he subsequently published the first report of the successful treatment of RDS with animal source surfactant in 1980.2 The techniques he used to recover and purify that surfactant were similar to those used in 1965 for these studies with premature infant lungs.
