| 摘 要： | 目的：探索老年性白内障与超氧化物歧化酶（superoxide dismutase,SOD)及血清中微量元素的相互关系。方法：检测61例老年性白内障患者血中红细胞SOD活性及患者血清微量元素（Cu、Zn、Ca、Fe），121例健康者作为SOD对照组，微量元素对照组为48例。结果：老年性白内障患者血中SOD活性较正常对照组明显下降，血清中微量元素C u、Zn、Ca并不降低，Fe元素高于正常对照组。结论：老年性白内障形成与眼部抗氧化能力下降有关。

| Abstract: | Purpose: To investigate the relation of senile cataract with superoxide disrautase(SOD) and trace elements.Methods: Superoxide dismutase of red blood cells and trace elements (Cu, Zn, Ca, Fe) of serum in 61 patients with senile cataract and 121 normal persons were investigated. Results: The activity of superoxide dismutase in patients with senile cataract decrease dramatically in comparison with normal control, and there was no statistical difference about trace elements of Cu, Zn, Ca between senile cataract and control group. But Fe element in patients is higher than that of the normal group.Conclusion: The results support the hypothesis that the formation of senile cataract is capable of antioxidative scavenger system of lens decreases with age.
