我们测定了３０位老年性白内障患者眼房水内及血清内的超氧化物歧化酶（ＳＯＤ－Ｉ）和脂质过氧化物（ＬＰＯ）。结果表明老年性白内障患者眼房水内超氧化物歧化酶含量较血清内低（Ｐ＜０．０１）。而房水内的脂质过氧化物含量却高于血清（Ｐ＜０．０５）。本文还分析了房水内超氧化物歧化酶含量减少，脂质过氧化物增多对老年性白内障的发生。发展的影响。推测由于外界因素诸如阳光、紫外线、辐射、外界温度等是造成房水内活性氧增多，破坏了房水内氧化──抗氧化系统间的平衡的主要原因之一。
We measured superoxide dismutase (SOD-I) and lipid peroxides (LPO) in 30 patients with cataract and aqueous humor. The results showed that the content of superoxide dismutase in aqueous humor of cataract patients was lower than that in serum (P <0.01). However, the content of lipid peroxidation in aqueous humor was higher than that in serum (P <0.05). This article also analyzed the aqueous humor content of superoxide dismutase, lipid peroxidation increased the incidence of senile cataract. Impact of development. It is speculated that due to external factors such as sunlight, ultraviolet radiation, the outside temperature is caused by an increase in reactive oxygen species in aqueous humor, destroying the oxidation of aqueous humor - one of the main reasons for the balance between antioxidant systems.
