摘要
观察了长期供应１／４～１／２万碘盐的ＩＤＤ病区妊娠妇女在孕前服与未服碘油丸（２００ｍｇ）对纠正体内碘代谢动态变化的影响。发现服碘油的孕妇血清ＴＳＨ、Ｔｇ值在孕３、５个月时降低，然后升高，Ｔ４、ＦＴ４升高持续到怀孕７个月，Ｔ３与ＦＴ３在３、５个月时恒定在孕前水平，然后下降，ｒＴ３在孕５个月时明显升高，揭示碘油仅能保护孕妇在妊娠期的前５个月不缺碘，在此时应再服一次小剂量碘油丸。碘盐组孕妇缺碘程度较未妊娠妇女对照组重，说明碘盐浓度偏低。
This pater demonstrated the dynamic canges of iodine metablism of the pregant women who took or didn't take iodized oil capsule(200mg) in IDD areas where one of forty thousand to one of twenty thousand iodized salt was applied for a long-term.The results showed:In the blood serum of the pregnant women who took iodized oil capsule before pregnancy,TSH and Tg were declined at the first five months,then increased;T 4 and FT 4 were increased during the seven months;T 3 and FT 3 during the first five months were as the same levels as before pregnancy,then declined;rT 3 was obviously increased after teh fifth months;iodine deficiency of pregnant women who didn't take iodized oil capsule was much severe than that of women who weren't pregnant.The results suggested that iodized oil capsule was effective only during the first five months of pregnancy,so the pregnant women should take low-dose iodized oil once again at the beginning of the sixth month of pregnancy;and the concentration of iodized salt was too low to guarantee the people who required specially for iodine.
