对６６例食碘盐１年以上，初发、典型、未经治疗的Ｇｒａｖｅｓ病伴甲亢患者（Ａ组）的甲状腺吸１３１Ⅰ率及其它临床特征与应用碘盐前的３４例甲亢患者（Ｂ组）进行了比较研究，发现如下特点：①甲状腺吸１３１Ⅰ率，４、６及２４小时均值，Ａ组略低于Ｂ组，两组间无显著性差异，两组吸１３１Ⅰ率高峰前移发生率亦无明显性差异（ｐ＞００５）；但４与２４小时吸１３１Ⅰ率的比值，Ａ组明显低于Ｂ组均值，两组间有显著性差异（ｐ＜００１）。②血清ＴＴ４、ＦＴ３、ＦＴ４均值及ＴＳＨ受抑（＜００３ｍｕ／Ｌ）的发生率，Ａ组均值明显高于Ｂ组，两组间有显著性差异（ｐ＜００１），但两组间ＴＴ３改变无显著性差异。③Ａ组的平均心率、突眼及甲状腺震颤发生率均明显高于Ｂ组（ｐ＜００１）。④ＭＣＡ及ＴＧＡ均值，两组间无显著性差异（ｐ＞００５）。结果表明，应用碘盐后，对甲亢患者及甲状腺吸１３１Ⅰ率和甲状腺功能以及甲状腺震颤、突眼的发生率都有显著影响。 Of 66 patients with iodized salt for more than 1 year, initial, typical, untreated Graves’ disease with hyperthyroidism (group A) 131I and other clinical characteristics of thyroid suction and iodized salt before the application of 34 patients with hyperthyroidism (group B ) Were compared and found the following characteristics: ① Thyroid 131I rate, 4,6 and 24-hour mean, A group slightly lower than the B group, no significant difference between the two groups, 131I rate of peak premature ejaculation in both groups There was no significant difference (p> 005). However, the ratio of 4 to 24 hours of 131 I absorption rate was significantly lower in group A than in group B, with significant difference between the two groups (p <001). (2) The mean of TT4, FT3, FT4 and TSH suppression (<003mu / L) were significantly higher in group A than in group B, with significant difference between the two groups (p <001) There was no significant difference in TT3 between groups. ③ The average heart rate, exophthalmos and thyroid tremor in group A were significantly higher than those in group B (p <001). ④MCA and TGA mean, no significant difference between the two groups (p> 0  05). The results show that the application of iodized salt, the patients with hyperthyroidism and thyroid suction 131I rate and thyroid function, as well as the incidence of thyroid tremor and exophthalmos have a significant impact.
