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。
In this paper, four groups of children were analyzed for their selenium content. The order was as follows: non-ward children> ward town staff children> ward farmers children> patients with new-onset keshan disease, the difference was very significant. Children in Ward and children in Keshan disease were in the condition of selenium deficiency; selenium in pre-school and school-age children showed no difference, while Keshan disease occurred frequently in preschool-age children. So that low selenium may not be the only cause of Keshan disease incidence; ward or non-ward children selenium did not differ in gender, consistent with the incidence of Keshan disease no difference.
