本文报道了母体缺碘对甲状腺功能始发前后大鼠胚胎组织中T_4和T_3含量的影响。作者将出生两个月的Wister雌鼠分为两组,分别饲以低碘食物(LID)和补充KI的低碘食物(LID+I)。饲养3个月后,两组雌鼠分别与正常雄鼠交配,在胚胎的甲腺功能始发前。即孕11、17及21天取出母体及胚胎的组织,用放免法测定,其中T_3和T_4的浓度。 结果发现,LID组雌鼠的血浆、肝和肺及取自该组雌鼠的所有胚胎样品,即孕11天的胚胎滋养层 This paper reports the effect of maternal iodine deficiency on the contents of T_4 and T_3 in rat embryos before and after thyroid function onset. The authors divided two-month-old Wister female rats into two groups: low-iodine (LID) and low-iodine (LID + I) supplemented with KI, respectively. After 3 months of feeding, the two groups of female mice were mated with normal males, respectively, before the onset of thyroid function in the embryos. That pregnant 11,17 and 21 days to remove the maternal and embryonic tissue, using radioimmunoassay, where T_3 and T_4 concentration. As a result, it was found that the plasma, liver and lungs of the females in the LID group and all the embryos taken from the females group, that is, the embryonic trophoblast
