在89份不同年龄甲状腺正常人的检查材料 mortem 后的甲状腺组织标本中测定了碘浓度。22周前胎儿甲状腺几乎不储存碘(平均24μg/g 湿重,范围0～27μg/g),从第23周始浓度明显的较高(p=0.004)。在出生 Iodine concentrations were measured in thyroid tissue samples from 89 mortem specimens of normal-aged thyroid glands at various ages. Twenty-two weeks ago, almost no iodine was stored in the fetal thyroid (mean 24 μg / g wet weight, range 0-27 μg / g), with significantly higher concentrations starting at week 23 (p = 0.004). At birth
