摘要
作者曾于1982年对云南小儿克山病患者头发中微量元素铜、锌、锰、铁、钼、铬、钴及常量元素钙含量进行了测定,结果表明,克山病区的患儿头发中锰、铁、钼含量极其显著地高于非病区正常儿童,而锌含量又显著低下。多元逐步判别分析揭示,在有差异的元素中,锰是一个主要因子。生物体受种种因素制约,单次的分析测定未必能提供某些规律性的结果。
Six elements(Cu,Zn,Mn,Fe,Mo,Ca)in hair,which was collected fromresidents in the endemic and non-endemic area of the Keshen disease inYunan province Dali Country,were fur-ther determinated by atomic absorptionspectrophotometry and polarography.The result is in agreement with thatpublished by us previouly.There are highly significant difference betweenchildren with disease and those in non-endemic area with respect to concentr-ation of Mn,Fe,Mo in the hair.But nodifference was found between patientsand normal children in endemic area.Discriminant function can not be sig-nificantly established for patients andnormal children in endemic area.But fornormal children in endemic area andnon-endemic area,larger contributiverate for discriminant function is conte-nts of Fe,Mo,Mn in hair.The conten-ts of Zn and Ca are lower in hair fromchildren than from adults.The largestcontributive rate for discriminant fun-ction of children and adults in endemicarea is contents of Fe and Zn in hair.It is suggested that in the light of theseresults of the survey,the influnce ofFe and Mn on metabolism of Se shouldbe further investigated.
