[The plasma amino acid profile of women with a normal pregnancy and in pre-eclampsia].
The authors studied the level of some amino acids in the plasma of 10 women with normal pregnancy as well as of 16 women with moderate form of pre-eclampsia. 21 amino acids were determined by a liquid chromatograph, consisting of an automatic controller of the gradient, nonautomatic injector, fluorimetric detector and recording device. The results showed that there were differences in amino-amides of women with normal pregnancy and of nonpregnant women. Concentrations of a large part of amino acids were not changed, but some of them increased--aspargic acid, glutamate, threonine and phenylalanine or reduced--cytroline, methionine, ornithine, glycine, aspargine, alpha-amino acid during pregnancy. The values of amino-acids in women with normal pregnancy and in women with moderate form of preeclampsia did not differ. Ethanol-amine is the only exception and it is found in almost half of the women with preeclampsia. This is an original finding, which deserves further study.
