The study comprised 12 lactating (L) women, 26 women who interruped the lactating during study (IL) and 6 women failing to lactate (NL). All women gave birth to normal fullterm infants after uneventfull pregnancy and vaginal delivery. Sampling was done during the 2nd day and 10th week after parturition. Lactating women showed more pronounced decrease of thyroxine, decreased thyroxine: triiodothyronine ratio and increased TSH level during the 10th week after parturition in comparison to IL group. The women on NL group showed similar changes as L women, but without increased level of TSH in comparison to IL ones. Results suggest the effect of lactation on the thyroid activity. This effect could be due to the loss of iodine and thyroid hormones to the milk.
该研究包括12名哺乳期（L）妇女、26名在研究期间中断哺乳的妇女（IL）和6名未泌乳的妇女（NL）。所有妇女均在妊娠和阴道分娩顺利后产下足月正常婴儿。在产后第2天和第10周进行采样。与IL组相比，哺乳期妇女在产后第10周时甲状腺素下降更为明显，甲状腺素：三碘甲状腺原氨酸比值降低，促甲状腺激素（TSH）水平升高。NL组妇女与L组妇女表现出相似的变化，但与IL组相比，TSH水平没有升高。结果表明哺乳对甲状腺活动有影响。这种影响可能是由于碘和甲状腺激素流失到乳汁中所致。
