云南克山病病区和非病区儿童头发中微量元素硒的对比分析

本文分析了四组儿童发硒,其含量高低依次为:非病区农户儿童>病区城镇职工户儿童>病区农户儿童>新发克山病的患者,差别均非常显著。病区农户儿童和克山病患者均处于贫硒状态状;学龄前和学龄儿童发硒无差异,而克山病却多发于学龄前儿童。因此认为低硒可能不是引起克山病发病的唯一病因;病区或非病区儿童发硒在性别上无差异,与克山病发病性别无差异相吻合。

A COMPARATIVE ANALYSIS OF THE TRACE ELEMENT SELNIUM IN CHILDREN''''S HAIR FROM AFFECTED AND NON-AFFECTED AREAS OF KESHAN DISEASE IN YUNNAN

Hair samples from four groups of children were analysed for selenium, its contetnt is arranged in order of amount as follows: that of children of peasant households in non - affected areas being highest, followed in turn by that of children of staff and workers in cities and towns in affected areas, that of children of peasant households in disease areas, and that of new sufferers of Keshan disease, with significant differences among them. Both children of peasant households in disease areas and those newly affected with Keshan disease were in a state poor in selenium. There was no difference between selenium levels in hair from preschool and school children. It is suggested that low level of selenium may not be the only cause for the pathogenesis of Keshan disease. No sex difference was found between hair selenium contents of children of affected and non - affected areas, being consistent with the observation that the pathogenesis of Keshan disease is unrelated to sex.
