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 ...

Effects of Calpain on Antioxidant Enzyme Activities

Free Radical Research, 1994
The activities of superoxide dismutase, catalase and glutathione reductase were not affected by in vitro incubation with the intracellular proteinase calpain, suggesting that these enzymes are not in vivo substrates of calpain. In contrast, the activity of another important antioxidant enzyme, glutathione peroxidase, is stimulated in vitro by calpain ...

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).

Pre-exercise antioxidant enzyme activities determine the antioxidant enzyme erythrocyte response to exercise

Journal of Sports Sciences, 2005
Free radical production increases during exercise and oxidative damage occurs in several tissues. We examined the effects of three different exercise tests on the pattern of change of erythrocyte enzyme antioxidant activities. The tests were a short maximal exercise test, a submaximal prolonged exercise test and a cycling stage during competition.

Antioxidant erythrocyte enzyme activities during oral contraception

Contraception, 1993
Nineteen healthy young women, non-smokers and of normal weight, used a combined oral contraceptive, consisting of 20 micrograms ethinylestradiol and 150 micrograms desogestrel, for 9 cycles and were investigated before starting oral contraceptive use, and during the 3rd, 6th and 9th cycle.

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.

Blood antioxidant enzymes during epileptic activity

Bulletin of Experimental Biology and Medicine, 1987
It has been shown that the development of generalized epileptic activity in rats led to the decrease in superoxide dismutase (SOD) activity without affecting glutathione peroxidase (GP) and glutathione reductase (GR) activity. Long-term examination of 13 patients suffering from generalized forms of epilepsy has shown an about 30% decrease in SOD and GP

Phenolic Acids and Antioxidants Profile, Antioxidative Enzymes and Antioxidant Activity of Mango

International Journal of Bio-resource and Stress Management, 2022
In an effort to evaluate the antioxidative property in mango, a laboratory study was conducted at BCKV, Mohanpur during 2019 with ten varieties of mango selected on the basis of popularity and area coverage. The pulp of the fruit samples harvested at the firm ripe stage showed wide genotypic variability in the contents of antioxidants and activity of ...
