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和血清铜锌含量。１７例发病７天内、４０例８～２０天内测定ＳＯＤ，与正常对照组（２５例）比较有显著和极显著差异。５７例血清铜，锌含量与正常对照组比较有显著差异；铜，锌含量与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增长ＳＯＤ活性下降，梗塞后血清铜、锌含量下降，显示微量元素与ＳＯＤ一样对脑梗塞后的脑细胞损害有着密切关系。
In this paper, radioimmunoassay and GFU-202 atomic absorption spectrophotometer determination of 57 patients with cerebral infarction in patients with SOD and serum copper and zinc content. Within 17 days of onset of disease, SOD was detected in 40 cases within 8-20 days after onset, and there were significant and extremely significant differences compared with the normal control group (25 cases). 57 cases of serum copper, zinc content compared with the normal control group were significantly different; copper, zinc content and SOD activity was significantly decreased (P <1%). It suggested that the activity of SOD decreased with the increase of course of disease. The level of serum copper and zinc decreased after infarction. It showed that trace elements and SOD were closely related to the damage of brain cells after cerebral infarction.
