摘要
柞水县地处秦岭深山,经济文化落后。地方性克汀病用碘盐预防得到控制之后,弱智儿童发病率仍然很高。通过对病区48名原因不明的弱智儿童追踪考察,发现患儿大脑额叶较小,脑电信号显示大脑发育幼稚,心脏各部比例异常。弱智与高锰和多基因遗传关系密切。
Zhashui county is located in the Qinbamountains which are backward in economyand culture.While.endemic cretinism hasbeen controlled with the administration ofsodium iodide,the incidence of low intel-ligence is still high.After trace explora-tion of 48 cases those causes were unkno-wn,we discovered that the frontal lobe oftheir brains were small;their electroence-phal development was poor and the propor-tion of the different parts of the heartwas abnormal.Obviously the causes of lowintelligence in this region are closely rela-ted to high manganese and polygenic inhe-ritance.
