白内障是目前全球范围内致盲的最主要原因,其中老年性白内障患者很多,老年性白内障的病因之一是眼晶状体受到氧化损害,这种氧化性损害中,尤以活性氧自由基的损害为重。当人们衰老时,保护人体免受自由基侵害的功能有所降低,活性氧自由基在眼内产生过量,因而引起眼内蛋白质尤其是α-和β-晶体蛋白的交联,同时眼内酶及膜蛋白中SH基受到氧化损害。此外,晶状体血浆膜脂质的过氧化更是一个重要的促发因素。尽管可以手术治疗,但在广大发展中 Cataracts are the most important cause of blindness in the world at present, among them there are many patients with senile cataract. One of the causes of senile cataract is that the lens of the eye is oxidatively damaged. Among these oxidative damages, the damage of reactive oxygen species weight. When people are aging, the function of protecting human body from free radical is reduced. Active oxygen free radicals are produced in the eye excessively, thus causing cross-linking of intraocular proteins, especially alpha- and beta-crystallin, while intraocular enzymes And SH protein in the membrane by the oxidative damage. In addition, the lipid peroxidation of the lens plasma membrane is an important contributor. Although surgery can be, but in the majority of development
