[The content of amino acids in the breast milk of nursing women].

Comparative quantitative and qualitative identification of free amino acids in the breast milk and plasma of puerperas (healthy individuals and those who had experienced gestosis during pregnancy) was made on a KNAUER-Aminosis A 200 amino acid analyzer on postpartum day 6. Clear direct correlations were found between the levels of essential amino acids in the breast milk and plasma; as well as the total content of all amino acids. When adequate sampled (on fasting) and processed (centrifugated and deproteinized), breast milk, a biological fluid, compares well with plasma samples in its diagnostic informative and biological value and it may be used as a subject for the noninvasive evaluation of the amino acid status of nursing mothers.
