[Comparison of lipoprotein spectrum and lipids in maternal blood and in umbilical cord blood of newborn infant].

Content of beta- and pre-beta-lipoprotein fractions, total cholesterol and triglycerides was distinctly lower in blood serum of infant than in maternal one. In serum of funicular blood content of free fatty acids was 2.5-fold higher than in maternal blood serum; in erythrocytes of infant content of cholesterol was found to be higher by 40%, as compared with maternal erythrocytes. In blood serum of infant content of free cholesterol amounted to 28% of the total cholesterol at the same time in maternal blood it was equal to 37%. The highest proportion of cholesterol was found in alpha-lipoproteins of infant, in mother it was observed in beta-lipoproteins. In blood of infant and mother the same types of lipoproteins were present but their quantitative ratio was different. The main lipoproteins of infant were shown to be alpha-lipoproteins. Relationship between the content of cholesterol in pre-beta-lipoproteins (correlation coefficient 0.64) was noted in blood of mother and infant.
