Thyroid hormones of amniotic fluids give informations about their presence in the fetus. T3 and T4, determined by radioimmunoassay, are found as soon as 12 weeks of gestation. Their amounts are higher at 17 weeks than at 30-40 weeks of gestation. Thyroid tissues of premature and full term neonates were analysed by chromatography after hydrolysis and 127I determined. T3 amount was very low near birth and increased with duration of survival. These results may be related to hormonal serum changes observed in the early neonatal period.
羊水甲状腺激素可提供其在胎儿体内存在的信息。通过放射免疫测定法测定的T3和T4在妊娠12周时即可检测到。其含量在妊娠17周时高于妊娠30 - 40周时。对早产和足月新生儿的甲状腺组织进行水解后通过色谱分析并测定127I。出生时T3含量非常低，并随存活时间延长而增加。这些结果可能与新生儿早期观察到的血清激素变化有关。
