碘硒联合补充控制碘缺乏病效应的研究

Studies on effects of IDD control by supplying iodine and selenium

为了探讨联合补充碘硒控制碘缺乏病的效应，作者在外环境缺碘地区，对实验组小学生在供应碘盐的同时每月口服一次２００ｍｇ亚硒酸钠片，对照组小学生单纯食用碘盐，２年后观察小学生甲状腺肿大率、尿碘、发硒和血清ＴＳＨ、Ｔ４、Ｔ３和ＦＴ３变化。结果表明，实验组小学生尿碘水平与对照组相当，发硒显著高于对照组，甲状腺肿大率显著低于对照组，血清ＴＳＨ、Ｔ４无显著差异，血清Ｔ３和ＦＴ３稍高于对照组但无统计学意义。

To study the effects of IDD control by supplying both iodine and selenium, we chose primary school pupils to observe in iodine and selenium deficient area Pupils. in experiment group were supplied with iodized salt and 1 tablet(200mg) of sodium selenite every month, all Pupils in contrast were supplied supplied with iodized salt alone. The variances of TGR, urinary iodine and serum TSH,T4,T3, FT3 in these pupils were observed after 2 years .TGR of pupils in experiment group was significantly We ho that of pupils in contrast group. Urinary iodine level in two groups was equal .Serum TSH,T4,T3 and FT3 showed no significant difference between two groups .So ,supplying both iodine and selenium was helpful to IDD control in the iodine - selenium deficient area.
