本文报道用中子活化分析法(NAA)测定了29例10～24岁的的克汀病人和11例当地健康学生头发的22种元素的含量,结果发现Fe、Cr、Br、As、V等元素的含量,克汀病人组低于正常人组;Mn、Se、Zn、Cu等含量克汀病人组高于正常人组。经t检验,必需微量元素Cr、Se、Br、As和其它宏量元素或主要元素Cl、Ca、Sb、Hg、Au两组均值差异非常显著(P<0.01),Mg、Na两组均值差异显著(P<0.05)。
In this paper, we measured the content of 22 elements in 29 cases of cretinism patients and 11 cases of local healthy students using neutron activation analysis (NAA). It was found that Fe, Cr, Br, As, V, etc. The content of elements, cretinism patients group is lower than that of normal people group; Mn, Se, Zn, Cu and other content cretinism patients group is higher than normal people group. After t test, the mean values of essential trace elements Cr, Se, Br, As and other macroelements or main elements Cl, Ca, Sb, Hg and Au were significantly different (P <0.01) Significant (P <0.05).
