我们应用原子吸收光谱法测定了４０例急性脑梗塞患者头发中Ｃａ，Ｍｇ，Ｃｕ，Ｚｎ的含量并与５０例正常老年人对照。患病组头发中Ｍｇ、Ｚｎ明显降低（二者均Ｐ＜０００１），Ｃｕ降低（Ｐ＜００５），Ｃａ无明显变化（Ｐ＞００５）。患病组男女病人差异不大。这些结果显示在急性脑梗塞的发生发展中Ｍｇ，Ｃｕ，Ｚｎ微量元素的变化具有重要临床参考价值，可能是发生急性脑梗塞的原因之一。
We measured the content of Ca, Mg, Cu, Zn in hair of 40 patients with acute cerebral infarction by atomic absorption spectrometry and compared with 50 normal controls. The levels of Mg and Zn in the diseased group were significantly lower (both P <0001), Cu decreased (P <005), and Ca did not change significantly (P> 005). There was no significant difference between male and female patients in the diseased group. These results show that the changes of trace elements of Mg, Cu and Zn in the development of acute cerebral infarction have important clinical reference value and may be one of the causes of acute cerebral infarction.
