铜丝置入兔眼玻璃体内,原子吸收分光光度法检测房水和玻璃体内微量元素铜,发现随着房水和玻璃体铜离子浓度的升高,视网膜脂质过氧化反应增强,并伴有视网膜电流图和超微结构的异常。实验结果表明,铜离子诱发的脂质过氧化反应是视网膜损伤的重要因素。 Copper wire was placed in the vitreous of rabbit eyes, and the atomic absorption spectrophotometry was used to detect the trace elements copper in aqueous humor and vitreous. It was found that the retinal lipid peroxidation increased with the increase of aqueous humor and vitreous copper ion concentration, Current diagrams and ultrastructural abnormalities. The experimental results show that copper ion-induced lipid peroxidation is an important factor of retinal damage.
