本文采用放免法和ＧＦＵ－２０２原子吸收分光光度计测定５７例脑梗塞病人的ＳＯＤ和血清Ｃｕ~(２＋)、Ｚｎ~(２＋)含量。５７例脑梗塞的ＳＯＤ和血请Ｃｕ~(２＋)、Ｚｎ~(２＋)含量与２５例正常对照组比较有显著差异（Ｐ＜０．０１）；Ｃｕ２＋、Ｚｎ２＋含量与ＳＯＤ活性下降呈十分显著正相关性（Ｐ＜１％）。提示脑梗塞病人随着病程的延长ＳＯＤ活性下降。梗塞后血清Ｃｕ~(２＋)、Ｚｎ~(２＋)含量下降显示微量元素与ＳＯＤ一样对脑梗塞后脑细胞损害有着密切关系。
In this paper, the determination of SOD and serum Cu ~ (2 +) and Zn ~ (2+) in 57 patients with cerebral infarction were measured by radioimmunoassay and GFU-202 atomic absorption spectrophotometer. The contents of Cu ~ (2 +) and Zn ~ (2+) in 57 cases of cerebral infarction were significantly different from those of 25 cases of normal control (P <0.01), and the contents of Cu2 +, Zn2 + and SOD decreased significantly Positive correlation (P <1%). Tip of patients with cerebral infarction with prolonged course of SOD activity decreased. The decrease of serum Cu ~ (2 +) and Zn ~ (2+) contents after infarction showed that trace elements and SOD were closely related to brain cell damage after cerebral infarction.
