精脒和精胺是天然多胺中研究得最多的两种物质。本文作者利用LKB4151自动化氨基酸分析仪对43名足月适于胎龄儿出生时脐血、出生后第三天静脉血及其母亲分娩时静脉血内精脒、精胺指标进行了研究;同时还对脐血内多胺指标与胎盘组织内DNA和RNA含量间的关系进行了探讨。
Spermidine and spermine are two of the most studied natural polyamines. The authors used the LKB4151 automated amino acid analyzer to study cord blood levels at the age of 43 gestational age at birth, venous blood on the third day after birth, and intravenous spermine and spermine levels at delivery of their mothers; meanwhile, The relationship between polyamine in cord blood and DNA and RNA content in placenta was explored.
