本文系根据1984、1985年云南克山病重病区(1984年含四川西昌部分病区)及非病区居民主食稻米、小麦和黄豆的氨基酸、蛋白质和微量元素 Cu、Zn、Mn、Se 的测定结果,又进一步对必需氨基酸、蛋白质和 Mn、Se 等12项指标,采用两个均值向量比较及两类逐步判别分析方法进行了综合分析,并讨论了它们的病因学意义。结果提示:此病区大米中蛋氨酸、硒低的复合作用可能最有意义。深入研究硒和蛋氨酸等复合因素的作用,在病因和发病机制研究中,会有所启示。
This article is based on the determination of amino acids, proteins and trace elements Cu, Zn, Mn and Se in rice from 1984 to 1985 in the Keshan Severe Ailments Region of Yunnan Province (including part of the Xichang Ward in 1984) and non-ward residents’ rice, wheat and soybean As a result, 12 amino acid, protein, Mn, Se and other 12 indexes were further analyzed by two mean value vectors and two kinds of stepwise discriminant analysis methods, and their etiological significance was discussed. The results suggest that the combined effects of methionine and selenium in rice in this ward may be most significant. In-depth study of the role of selenium and methionine and other complex factors in the etiology and pathogenesis, there will be some inspiration.
