为了深入探讨老年性白内障的发病机理及其与硒的关系，本文利用美国Ｐ－Ｅ公司生产的电感耦合等离子体光谱仪（ＩＣＰ）对３７例老年性白内障的患者进行血清硒含量的测定。根据临床检查晶体混浊部位将患者分为：①以后囊混浊为主的后囊型白内障。②以核混浊为主的核型白内障。③以皮质混浊为主的皮质型白内障三种。结果发现：①本实验室正常人血中硒含量为８９±１７．２ｕｇ／１。而患老年性白内障患者血清硒含量明显高于正常人；②后囊型白内障与核型白内障者血清硒含量亦明显高于皮质型白内障，但前二者之间比较，血清硒水平相差不显著，皮质型白内障患者血硒水平显著低于正常值；③性别不同，血清硒水平无明显差异。结论：①过高和过低的血清硒水平均可与老年性白内障的发生有关；②后囊型和核型白内障血清硒含量过高。而皮质型白内障与血清硒含量过低有关。
In order to investigate the pathogenesis of senile cataract and its relationship with selenium, the selenium content in sera of 37 patients with senile cataract was determined by inductively coupled plasma spectrometer (ICP) manufactured by American P-E company. According to the clinical examination of the opacity of the lens will be divided into patients: ① posterior capsule opacification-based posterior capsular cataract. ② nucleus-dominated nuclear cataracts. ③ mainly cortical cortical cataract three. The results showed: ① The selenium content of normal human blood in our laboratory was 89 ± 17.2ug / 1. Selenium content in patients with senile cataract was significantly higher than that in normal people. ② Selenium content in posterior capsular cataract and karyotypic cataract was also significantly higher than cortical cataract, but the difference between the former two groups was not significant , Selenium in patients with cortical plasma blood levels were significantly lower than normal; ③ gender, serum selenium levels were no significant differences. Conclusions: ①Overly high and low serum selenium levels may be related to the occurrence of senile cataract. ② The serum selenium content of posterior capsule and karyotype are too high. The cortical cataract and serum selenium content is too low.
