老年性白内障占我国白内障的63.1％,也是我国致盲眼病的第1～2位,且南方明显高于北方。其发病原因可为外因(主要是紫外线辐射)及内因如血脂、营养、内分泌与遗传等多方面因素而使透明晶状体变为混浊。晶状体蛋白主要是传递、吸收光线及光的折射,而水合作用与粘多糖对晶状体透明性亦起作用。因此,晶状体蛋白的合成与水合作用障碍便使晶状体混浊。研究晶状体蛋白成份,将有利于探讨白内障的发病机制。近年来由于生化与免 Senile cataract accounts for 63.1% of China’s cataracts, which is also the first to the second of China’s blind eye, and the south is significantly higher than the north. Its causes may be due to external factors (mainly UV radiation) and internal factors such as blood lipids, nutrition, endocrine and genetic factors make the transparent lens becomes cloudy. Crystalline protein is mainly transmitted, absorbing light and light refraction, and hydration and mucopolysaccharides also play a role in lens transparency. Therefore, the lens protein synthesis and hydration disorders make the lens turbid. The study of the lens protein components, will help to explore the pathogenesis of cataract. In recent years due to biochemistry and immunity
