Abstract
Some evidence suggests the neuroprotection of estrogen provided by the antioxidant activity of this compound. The main objective of this study was to determine the level of estradiol and its correlation with the activity of antioxidant enzymes, total antioxidant status and ferritin from ischemic stroke subjects. The study population consisted of 30 patients with acute ischemic stroke and 30 controls. There was no significant difference between estradiol in stroke and control group. The activity of superoxide dismutase and level of ferritin was higher in stroke compared with control group (P < .05, P < .001, resp.). There was no significant correlation between estradiol and glutathione peroxidase, glutathione reductase, catalase, total antioxidant status, and ferritin in stroke and control groups. We observed inverse correlation between estradiol with superoxide dismutase in males of stroke patients (r = −0.54, P = .029). Our results supported that endogenous estradiol of elderly men and women of stroke or control group has no antioxidant activity.Keywords
