[Serum lipids and electrophoresis of lipoproteins in the normal newborn infant].
The levels of plasma lipids and the values of the different electrophoretic fractions of lipoproteins were measured in cord blood of 300 new borns selected at random. The value found are expressed as me +/- S.D. (limits X +/-2s) and were the following: total cholesterol 80.4 +/- 17.5 (limits 45-115) mg./100 ml., LDL cholesterol (by precipitation) 33+/-11 (limits 11-55) mg./100 ml., betalipo-protein (by immunodifusion) 142.7+/-26.4 (limits 90-195) mg./100 ml. and triglycerides 35+/-13 (limits 9-61) mg./100 ml. The figures for the different electrophoretic fractions of lipoproteins were expressed in per cent of the total area and were the following: betalipoproteins 42.9+/-10.3 (limits 22-63%), prebetalipoproteins 3.09+/-2.79 (limits 0-8.6%) and alphalipoproteins 53.8 +/- 9.5 (limits 35-73%). The beta/alpha ratio was 0.91+/-0.33 (limits 0.25-1.6).
