[Free amino-acids of the plasma in atherosclerotic patients (author's transl)].

18 free amino-acids have been valuated in a group of patients recovering from myocardial infarction dating more than one year back and in another group of healthy active athlets. In the group of the ill persons the mean values of the following amino-acids were significantly higher: Arginine, asparagine-acid, phenylalanine, valine, lysine, serine, threonine, leucine, proline and tyrosine. While in the group of the healthy persons the following amino - acids proved to have significantly higher values: alpha -- aminobutter-acid, glycine and cystine. No significant differences between the mean values of both groups were to be found of the following amino - acids: Alanine, methionine, ornithine, isoleucine and histidine. In the group of the patients correlations of the free amino acids to both serumlipids and blood -- glucose could be calculated with significant results in a certain number of amino-acids. The results may suppose that the changes in the metabolism of atherosclerotic patients do not only effect the lipids and carbohydrates, but as well the free amino-acids.
