[Intraamnial application of 14C-labeled lecithine at man 13 hrs. ante partum (author's transl)]

It was examined, whether by intraamnial applicated lecithine an approaching respiratory distress syndrome could be prevented. This possibility of therapy was tested on a fetus unviable of life. It was shown by examining the lavage-fluid of the fetal lung, as well as the organ homogenates of lung; liver and gut, that the intraamnial applicated lecithine was metabolised and resynthesised in the organism. In the lung the lecithine was present as a complete molecule.
