title: [The spectrum of fatty acids during lactation in women].
abstract: The large spectrum of fatty acids (expressed in relative values) was studied in the breast-human milk during the first three weeks of the lactation (3rd, 5th, 10th and 20th day after delivery). All women passed the pregnancy and the delivery without any pathological syndrome and their neonates were found as a healthy and physiological too. No drug dependency was registered. Fatty acids were measured as methyl-esters (FAME) using the method of gas chromatography (1). During the 20 days after delivery and of lactation period, summarising the groups of fatty acid (saturated, monoenoic, PUFA n-3, n-6 and n-9) only few changes could be detected: the increase of the participation of saturated fatty acids of short-medium chain (8:0, 10:0 and 12:0) and of PUFA n-9. Compared with the most administered commercial formula Feminar, the visible differences in the participation of fatty acids were described. Finally: during the lactation we could obtain a large number of significant differences of such individual fatty acids as palmitic acid, arachidonic acid, eicosopentaenoic acid, linoleic acid ect. The possible reasons of such changes during the lactation are discussed and these results are compared with our previous data concerning the fatty acid- spectrum in blood plasma of healthy newborns and preterm or hypoxic infants.
