the proportion of dipalmitoylphosphatidylcholine in the phosphatidylcholine species increased from 20.9 +/- 2.1 % in the foetal lungs of the control group to 22.6 +/- 5.0 % in the l-carnitine group , to 24.3 +/- 3.3 % ( p less than 0.01 ) in the betamethasone-l-carnitine ( 20 mg/kg ) group , to 25.2 +/- 3.5 % ( p less than 0.01 ) in the betamethasone group , to 27.1 +/- 2.6 % ( p less than 0.01 ) in the betamethasone-l-carnitine ( 40 mg/kg ) group , and to 28.4 +/- 3.7 % ( p less than 0.01 ) in the betamethasone-l-carnitine ( 80 mg/kg ) group , while the palmitic acid portion in the phosphatidylcholine fatty acids was nearly unchanged .
