测定足月和妊娠各个阶段胎盘组织中的多胺和核酸水平。足月时胎盘中腐胺亚精胺和精胺的浓度在 9 至 13 nM/g 组织范围内，低于妊娠第 1 个月期间的多胺水平。精胺和亚精胺的浓度差异具有统计学显着性（p 小于 0.01），但腐胺的浓度差异不显着。 RNA/DNA 比率从妊娠第 1 个月的 1.03 降至 9 个月时的 0.59。
The levels of polyamines and nucleic acids were determined in placental tissue at full term and at various stages of gestation. The concentrations of putrescine spermidine and spermine in the placenta at full term were in the range of 9 to 13 nM/g tissue and were lower than polyamine levels during the 1st trimester of pregnancy. The differences in concentration were statistically significant (p less than .01) for spermine and spermidine but not for putrescine. The RNA/DNA ratio decreased from 1.03 during the 1st trimester to .59 at 9 months.
