作者分析了43名妊娠20—30周妇女的血浆游离氨基酸含量,并与婴儿出生体重间的相关进行了分析。33个足月分娩正常婴儿,10个为胎生营养不良婴儿(简称 FM),他们的出生体重/胎令比值在正常的68%以下;在10个中有3个因母亲有妊娠毒血症而早产,7个为足月 FM 婴儿。结果表明,妊娠26周母血浆中天门冬氨酸、丝氨酸、丙氨酸、酪氨酸、鸟氨酸、精氨酸的水平与校正的新生儿大小有显著正相关,而蛋氨酸与之有显著的负相关。校正的新生儿大 The authors analyzed plasma free amino acid levels in 43 women 20-30 weeks of gestation and analyzed their association with infant birth weights. Thirty-three full-term deliveries of normal infants, 10 of them were maternal malnutrition infants (FMs) whose birth weight / births ratio was below normal 68%; of 10 out of 10 mothers with gestational toxemia Preterm birth, 7 full term FM infants. The results showed that the levels of aspartate, serine, alanine, tyrosine, ornithine and arginine in maternal plasma were significantly positively correlated with corrected neonatal size at 26 weeks of pregnancy, while methionine was significantly associated with it The negative correlation.
