某些疾病致血清过氧化脂质水平增高,最终导致细胞结构和功能改变,特别是动脉硬化性血管改变。Glavind等已首先报道动脉病变的程度与动脉壁中含有的过氧化脂质之间有着高度相关性。Yoshitak等观察,白内障的形成和过氧化脂质有关,且糖尿病性白内障晶体内过氧化脂质更比老年性白内障为高;老年性和糖尿病性白内障晶体内超氧化物歧化酶(SOD)都低于正常值;因此认为,糖尿病性白内障的生成主要是由于抗氧化酶,特 Some diseases cause an increase in serum lipid peroxidation levels, eventually leading to changes in cellular structure and function, especially atherosclerotic vascular changes. Glavind et al. Have first reported a high degree of correlation between the degree of arterial lesions and lipid peroxides contained in the arterial wall. Yoshitak observed that the formation of cataracts and lipid peroxidation, and diabetic cataract crystal lipid peroxide more than senile cataract is high; senile and diabetic cataract lens superoxide dismutase (SOD) are low At normal values; so that the formation of diabetic cataracts is mainly due to antioxidant enzymes, especially
