Antioxidant enzyme activities and malondialdehyde levels related to aging

Clinica Chimica Acta, 2001
Free oxygen radicals have been proposed as important causative agents of aging. We have evaluated age-related changes in antioxidant enzyme activities and lipid peroxidation.We measured erythrocyte superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and plasma malondialdehyde (MDA) levels.

The Changes in Endogenous Antioxidant Enzyme Activity After Postconditioning

Cellular and Molecular Neurobiology, 2006
1. The aim of this work was to study potential mechanisms participating in postischemic protection of selectively vulnerable CA1 neurons in the hippocampus. Experiments were focused on measuring changes in endogenous antioxidant enzyme activity. 2. Forebrain cerebral ischemia was induced in a rat by four-vessel occlusion.

Upregulation of Antioxidant Enzyme Activities by Deprenyl

Annals of the New York Academy of Sciences, 1996
In order to elucidate the exact role of antioxidant enzyme activities such as superoxide dismutase (SOD) in the aging process of animals, we compared various enzyme activities in different brain regions and in the liver of young (6-8 mo) and old (28-30 mo) Fischer-344 (F-344) rats.

Antioxidant enzyme activities and oxidative stress in affective disorders

International Clinical Psychopharmacology, 2004
Recent data from several reports indicate that free radicals are involved in the biochemical mechanisms underlying neuropsychiatric disorders in human. The results of several reports suggest that lower antioxidant defences against lipid peroxidation exist in patients with depression and that there is a therapeutic benefit from antioxidant ...

Lipoperoxidation and antioxidant enzymes activity in pregnancy complicated with hypertension

European Journal of Obstetrics & Gynecology and Reproductive Biology, 1996
To assess maternal circulating levels of lipid peroxidation breakdown products and antioxidant enzymes activity in pregnancies complicated with hypertension.Ten women with uncomplicated pregnancies and nine women with hypertension antedating pregnancy were prospectively sampled.

Activities of antioxidant enzymes and lipid peroxidation in endometrial cancer

European Journal of Cancer, 1993
Antioxidant enzyme activities and lipid peroxidation were analysed in normal endometrium and endometrial cancer tissues from Finnish and Japanese patients. The catalase and glutathione peroxidase activities of normal endometrium were significantly lower in Finns than in Japanese.

Ozone tolerance and antioxidant enzyme activity in soybean cultivars

Photosynthesis Research, 2000
The current study confirmed earlier conclusions regarding differential ozone (O(3)) tolerances of two soybean cultivars, Essex and Forrest, and evaluated antioxidant enzyme activities of these two varieties based on their performance under environmentally relevant, elevated O(3) conditions. The experiment was conducted in open-top chambers in the field

[Platelet antioxidant enzyme activities in arteriopathy].

Pathologie-biologie, 1988
Some publications have pointed out that oxygen free radicals can induce injury of vessel wall and increase platelet aggregation and clotting, which can suppose a dependent relationship with arteriosclerotic process. We therefore studied the hypothesis of a possible abnormal platelet antioxidant enzymatic equipment in arteriopathic patients.

Antioxidant Enzymes Activity in Diabetic Patients

2003
A group of 109 patients with type 2 diabetes mellitus (DM), subdivided in insulin treated (N=56) and non-insulin treated (N=53) subgroups, and 102 non-diabetic control subjects were assessed for key antioxidant enzymes activity in the serum: superoxide dismutase (SOD), catalase and glutathione peroxidase (GLPX) as well as for total antioxidant status ...
