白血病(血癌)发病率国内外均有逐年增高的趋势。为研究该病与微量元素谱的关系,本文据马氏(Mahalanobis)距离判别法,用BASIC语言编制适用于普通微型计算机用的多元判别程序,对74例急性白血病(简称急白)和30例健康人血清中Mn、Zn、Ni和Cu含量进行判别分类研究。对上述四元素进行显著性检验,急白患者与健康人相比,其锰、锌含量明暴偏低,有非常显著性差异,镍、铜含量虽高,但仅镍有显著性差异,铜无统计学意义。在任两元素间的浓度比值中,锰镍比、锰铜比有非常显著性差异,锰锌比、镍铜比、镍锌比和铜锌比也有显
The incidence of leukemia (leukemia) both at home and abroad have increased year by year trend. In order to study the relationship between the disease and the trace element spectrum, this paper based on the Mahalanobis distance discrimination method, using BASIC language for multivariate discriminant program for ordinary micro-computer, 74 cases of acute leukemia (referred to as acute white) and 30 cases Study on the Classification of Mn, Zn, Ni and Cu Contents in Healthy Human Serum. Significant test of the above four elements, acute white patients compared with healthy people, the manganese, zinc content of the low storms, there is a very significant difference, although the nickel and copper content is high, but only significant differences in nickel, copper No statistical significance. In any concentration ratio between two elements, the ratio of manganese to nickel, manganese and copper ratio has a very significant difference, Mn-Zn ratio, nickel-copper ratio, nickel-zinc ratio and copper-zinc ratio also significant
