A study was undertaken to evaluate oxidative stress and oxidative defense mechanisms in 14 cases of Eales disease with retinal periphlebitis and 10 controls. Alterations in activity of the enzymes sueeroxide dismutase and catalase in platelets and the lipid peroxidation product malondialdehyde were estimated biochemically. Enhanced oxidative stress (significantly increased malondialdehyde levels and decreased superoxide dismutase enzyme activity) was detected. Results suggest involvement of free radicals in the pathogenesis of Eales disease.
开展了一项研究,评估14例伴有视网膜静脉炎的Eales病病例和10例对照组的氧化应激及氧化防御机制。通过生化方法估算了血小板中超氧化物歧化酶和
过氧化氢酶的活性变化,以及脂质过氧化产物
丙二醛的
水平。检测到氧化应激增强(
丙二醛水平显著增加,超氧化物歧化酶酶活性降低)。结果表明自由基参与了Eales病的发病机制。
