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Cu、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。眼科学报2000;16:246～248
Objective: To explore the relationship between senile cataract and superoxide dismutase (SOD) and trace elements in serum. Methods: The activity of erythrocyte superoxide dismutase (SOD) and serum trace elements (Cu, Zn, Ca, Fe) in 61 senile cataract patients were detected, and 121 healthy controls were used as SOD control group. The trace element control group was 48 cases. Results: The activity of SOD in the blood of senile cataract patients was significantly lower than that of the normal control group. The contents of trace elements Cu, Zn and Ca in serum were not decreased, while the content of Fe was higher than that of the normal control group. Conclusion: The formation of senile cataract is related to the decrease of anti-oxidative ability in the eyes. Journal of Ophthalmology 2000; 16: 246 ~ 248
