ABSTRACT
Dipalmitoyllecithinic (DPL) is the quantitatively largest and most active portion of the surfactant system. Hence only a quantitative DPL determination allows a relevant statement of fetal lung maturity. The antenatal prophylaxis of RDS should result in an increase of the DPL-level in a fetal lung. A new gaschromatographical method for determination of DPL was developed. The results were secured by gaschromatography-mass-spectrometry-couplings. After treatment with betamethasone an increase of the relative DPL-amount in fetal rat lung lecithin species was found, but not an increase of the lecithin-level in the lung-tissue. Corticosteroids probably induce transesterification of the lecithins.
