Activity of superoxide dismutase obtained from senile cataract lens - effect of diabetes mellitus.
The activity of Cu,Zn superoxide dismutase in the fluid obtained from eye lens capsules after cataract surgery was investigated in samples obtained from patients with senile cataract and with senile cataract combined with diabetes mellitus. Two parameters were measured and compared: the frequency of occurrence of detected superoxide dismutase activity and the relative activity of the enzyme in ...
متن کاملEffects of histone acetylation on superoxide dismutase 1 gene expression in the pathogenesis of senile cataract
Histone acetylation plays key roles in gene expression, but its effects on superoxide dismutase 1 (SOD1) expression in senile cataract remains unknown. To address this problem, the study was to investigate the influence of histone acetylation on SOD1 expression and its effects in the pathogenesis of senile cataract. Senile cataract was classified into three types-nuclear cataract (NC), cortical...
متن کاملThe effect of metal deposition on antioxidant enzymes of lens in smokers of Karachi, Pakistan
Background: Blindness due to cataract is a major and important problem in Pakistan. The problem is expected to increase in future due to increase in tobacco smoking. The aim of study was to look for the mechanism associated with metal deposition and its effect on antioxidant enzymes in lens of smokers in Karachi, Pakistan. Methods: 20 cataract patients were randomly selected from Out Patient De...
متن کاملOestradiol levels and superoxide dismutase activity in age-related cataract: a case–control study
BACKGROUND It has been suggested that the higher prevalence of cataract in women is caused by a withdrawal effect of oestrogen at menopause. In vitro studies have demonstrated protection of serum oestradiol (E2) against oxidative stress through upregulation of antioxidant enzymes, including superoxide dismutase (SOD). The purpose of the present study was to investigate E2 levels and SOD erythro...
متن کاملLens superoxide dismutase and catalase activities in diabetic cataract.
OBJECTIVE Biochemical evidence suggests that the oxidative damage of the lens proteins is involved in the genesis of senile cataract and the development of diabetes-related pathologic changes such as the formation of cataracts. In particular, lens proteins are subject to extensive oxidative modification. Oxidative damage either decreases the antioxidant capacity or decreased antioxidant capacit...
