Species variation in lung antioxidant enzyme activities

Journal of Applied Physiology, 1987
Exposure of several different animal models to O2-induced lung injury has revealed marked differences in sensitivity of various species to O2 damage. These differences may be due in part to variation of cellular antioxidant defenses. To characterize lung antioxidant enzyme activities in different species, we measured lung activities of glutathione ...

ERYTHROCYTE ANTIOXIDANT ENZYME ACTIVITIES IN CHILDREN WITH MYELOMENINGOCELE

Developmental Medicine & Child Neurology, 1995
SUMMARYErythrocyte free radical scavenging enzyme activities and their cofuctor trace elements in plasma were assessed in 26 selected patients with myelomeningocele, both parents from 10 selected families, and 14 healthy adult controls. All index children except one were deficient in erythrocyte glutathione peroxidase (GSH‐Px).

Serum antioxidant enzyme activity in Parkinson's disease

Molecular and Cellular Biochemistry, 1992
The activities of superoxide dismutase (SOD; EC 1.15.1.1) and glutathione peroxidase (GSHPx; EC 1.11.1.9), the enzymes that metabolize the superoxide anion and hydrogen peroxide, respectively, were measured in serum from healthy subjects and patients with Parkinson's disease (PD).

Antioxidant Enzyme Activity in the Maturing Rat Testis

Journal of Andrology, 1992
Abstract: Developmental profiles of the activity of the antioxidant enzymes superoxide dismutase (SOD), catalase, glutathione peroxidase (GSH‐Px), glutathione transferase (GSH‐Tr), and hexose monophosphate shunt (HMS) were measured in the rat testis and liver.

The antioxidant enzymes activity in the conditions of systemic hypersilicemia

Biological Trace Element Research, 1994
The effect of an excessive inorganic silicon oral intake on the activity of basic antioxidant enzymes was studied in rats. Activities of superoxide dismutase, catalase, and glutathione peroxidase were measured in liver and kidney tissues of animals receiving per os sodium metasilicate nonahydrate (Na2SiO3.9H2O) (Sigma, [St.

Lipid Peroxidation and Antioxidative Enzyme Activities in Childhood Epilepsy

Journal of Child Neurology, 2002
This study aimed to investigate the relationship among lipid peroxidation, subsequent activation of scavenger enzymes (superoxide dismutase and glutathione peroxidase), and the presence of structural abnormality in 52 epileptic children receiving monotherapy (medically responsive) or polytherapy (medically intractable).

Antioxidative enzyme activities in wheat genotypes

Cereal Research Communications, 2006
Activities of superoxide dismutase (SOD), guaiacol peroxidase (PX), glutahione peroxidase (GPX) and catalase (CAT) as well as formation of malondialdehyde (MDA) and liposoluble fluorescent compounds (LFC) in leaves of 20 wheat genotypes, parents and hybrids of F1 and F2 generation were examined.

Enzyme-Catalyzed Change of Antioxidants Content and Antioxidant Activity of Asparagus Juice

Journal of Agricultural and Food Chemistry, 2006
A pectolytic enzyme preparation from Aspergillus niger (pectinase AN) decreased most rutin content and antioxidant activity of asparagus juice. To investigate the mechanism of such loss, we analyzed several possible related enzyme activities in pectinase AN.

Activities of conjugating and antioxidant enzymes following endotoxin exposure

Journal of Biochemical and Molecular Toxicology, 1999
Endotoxin exposure elicits various responses in mammals including the acute phase response that has been shown to cause changes in the activity of several forms of cytochrome P450s and other enzymes. Therefore, the hepatic conjugating enzyme, glutathione S-transferase (GST), and UDP-glucuronosyltransferase (UDPGT), the antioxidant enzymes, glutathione ...

Antioxidant enzymes and sport activity

2019
Strenuous physical exercise generates intracellular free radicals which may impair the pro-oxidant to antioxidant balance thus resulting in an oxidative stress which led to cell biomolecules damage. In this paper a survey of the main antioxidant enzyme systems involved in the sport activity is presented.
