We measured concentrations of thyroxine, triiodothyronine, reverse triiodothyronine, thyroxine-binding globulin, and thyrotropin in pooled samples of cord sera from normal newborns. Sera collected in winter contain significantly (p less than 0.05) higher concentrations of the first tour--14.9, 13.4, 9k9, and 7.5%, respectively--than do sera collected in summer; thyrotropin concentrations are similar in samples collected during winter and summer (p greater than 0.05). With storage, the values for the thyronines and thyrotropin decreased progressively at rates between 0.9 and 5.3% per year; those for thyroxine-binding globulin did not change significantly.
我们测定了正常新生儿脐带血清混合样本中甲状腺素、三碘甲状腺原氨酸、反三碘甲状腺原氨酸、甲状腺素结合球蛋白和促甲状腺激素的浓度。冬季采集的血清中，前四种物质的浓度分别比夏季采集的血清显著（p<0.05）高14.9%、13.4%、9.9%和7.5%；冬季和夏季采集的样本中促甲状腺激素浓度相似（p>0.05）。随着储存时间的延长，甲状腺素和促甲状腺激素的值以每年0.9%至5.3%的速率逐渐下降；甲状腺素结合球蛋白的值没有显著变化。
