| Abstract |
|
Lipid consumption in early life has been implicated with atherosclerosis in later life. It has been also claimed that lipids contents of serum in early life would reflect coronary atherosclerosis in later life. Present study has undertaken to look for the composition of serum HDL and fatty acid composition of serum cholesteryl esters in newborns. Levels of high density lipoprotein (HDL) cholesterol, HDL-triglycerides, and HDL-phospholipids were determined after elimination of low density and very low density lipoproteins by sodium phophotungstate-Mg
precipitation procedure. Fatty acid composition of serum cholesteryl esters was measured by gas-liquid chromatographic method. In comparison with adults, HDL-G, HDL-TG, concentration were decreased, but HDL-PL
was significantly increased. However HDL-C/TC, HDL-TG/TG, and HDL-PL/PL ratio were significantly increased compared with those of adults. The statistically significant decrease in 18 : 2/18 : 2 ratio was observed in serum cholesteryl esters of newborns.
