作者从前的研究已经证明:正常人短期服用1500μg/d～250mg/d 碘化物,有抑制其甲状腺激素分泌的作用。在美国,碘化物摄入量高达800μg/d。因此,本文作者研究了补充很小剂量碘化物对正常人甲状腺功能的影响。病例及方法 30名年龄在22～40岁(平均27岁)的正常人,随机分成3组。分别摄入碘化物500、2500及4500μg/d共2周。试验前一天,所有试验者禁食8h 后,收集共24h 尿标本以测定尿碘及尿肌酐含量。服碘化物前先测定血清甲状腺素(T_4)、三碘甲腺原氨酸(T_3)、T_3摄取率(T_3U)、甲状腺刺激激素
The author’s previous studies have shown that: normal short-term use of 1500μg / d ~ 250mg / d iodide, inhibit its role in thyroid hormone secretion. In the United States, iodide uptake of 800μg / d. Therefore, the authors investigated the effect of supplementing small doses of iodide on normal thyroid function. Cases and Methods 30 normal subjects aged 22-40 years (average 27 years old) were randomly divided into 3 groups. Iodine 500, 2500 and 4500 μg / d were consumed for 2 weeks respectively. On the day before the test, all subjects were fasted for 8 hours and collected a total of 24 hours urine samples to determine urinary iodine and urinary creatinine. Serum thyroxine (T_4), triiodothyronine (T_3), T_3 uptake (T_3U), thyroid stimulating hormone
