该项研究确定分析了 1 2 4个案例 (其中有 73例糖尿病人和 5 1例对照组健康人 )血清和头发样品中的微量元素铁 (Fe) ,铜 (Cu) ,锌 (Zn) ,硒 (Se)和宏量元素钙 (Ca) ,镁 (Mg)含量水平。头发样品中的这 6种矿物元素和血清中的Se是采用催化极谱方法分析的 ,血清中的其余 5种矿物元素则是用火焰原子吸收方法分析的。结果显示 ,如取显著性水平α =0 .0 5 ,则糖尿病人头发样品中的Cu(9.2± 2 .7ppm)显著低于对照组头发样品中的Cu(1 0 .4± 2 .9ppm) ,而发Fe(1 9± 9ppm)则显著高于对照组的发Fe(1 6± 8ppm)。但糖尿病人头发样品中的Mg ,Ca ,Zn和Se含量水平并未显示出显著变化。对于血清样品 ,显著性水平仍取α =0 .0 5 ,糖尿病人血清中的Zn(1 .0± 0 .4 μg/ml)显著低于对照组血清中的Zn(1 .3± 0 .6 μg/ml) ,而糖尿病人血清Cu(1 .0 2± 0 .2 3μg/ml)则显著高于对照组血清Cu(0 .92± 0 .1 8μg/ml)。对于血清样品中的Mg ,Ca ,Fe和Se含量水平病人与健康人之间的差别不显著。这些结果与其他一些研究者所得的结论是基本一致的。特别应该加以注意的是 ,铜在糖尿病患者的头发、血清中高低显著变化的不一致性 ,同时应注意铁在头发中的异常变化。若要通过头发分析来探讨矿物元素与糖尿病的关联性 ,铁和铜是两个值得
The study identified the presence of trace elements such as Fe, Cu, Zn, and Zn in serum and hair samples of 124 cases (73 of them diabetes and 51 healthy controls) Se and Ca, Mg. The six mineral elements in the hair sample and Se in the serum were analyzed by catalytic polarography and the remaining five mineral elements in the serum were analyzed by flame atomic absorption spectrometry. The results showed that Cu (9.2 ± 2 .7 ppm) in diabetic hair samples was significantly lower than Cu (104 ± 2 .9 ppm) in control hair samples if the significance level α = 0.05 was used Fe (1 9 ± 9 ppm) was significantly higher than Fe (16 ± 8 ppm) in the control group. However, levels of Mg, Ca, Zn and Se in diabetic hair samples did not show significant changes. For the serum samples, the significance level still took α = 0. 05, and the serum Zn (1. 0 ± 0. 4 μg / ml) in diabetic patients was significantly lower than that in the control group (1. 3 ± 0. 6 μg / ml), while serum Cu of patients with diabetes was significantly higher than that of the control group (0.92 ± 0.18 μg / ml). There was no significant difference between patients and healthy individuals for levels of Mg, Ca, Fe, and Se in serum samples. These results are basically consistent with the conclusions obtained by some other researchers. In particular, it should be noted that there is significant inconsistency between the levels of copper and copper in the hair and serum of diabetic patients. At the same time, attention should be paid to the abnormal changes of iron in the hair. To explore the relevance of mineral elements to diabetes through hair analysis, iron and copper are two worthwhile
