Protecting antioxidative effects of vitamins E and C in experimental physical stress
TLDR
A protective effect against oxidative stress produced by swimming in animals treated with vitamins E and C is pointed out, which is expressed through the diminution of the malondialdehyde quantity both in erythrocytes and in the heart, and through the conservation of GSH content in both products. Expand
Characterization of some extractive fractions isolated from raw Allium cepa L. bulbs.
TLDR
Both investigated extracts possess interesting antioxidant properties which are significantly influenced by their chemical composition. Expand
Effects of dietary flaxseed supplementation on renal oxidative stress in experimental diabetes.
TLDR
Dietary flaxseed supplementation in diabetes mellitus may have beneficial effects on diabetic nephropathy evolution by reducing the levels of oxidative stress and increasing the antioxidant defense systems. Expand
Influence of light-dark cycle alteration on free radical level in rat cns.
TLDR
Redox system spatio-temporal versatility and complementarity suggested the existence of a possible biochemical radical cell clock gear in the central nervous system regions investigated. Expand
Antioxidant activity in rat models of nociceptive stress.
TLDR
This experiment has revealed that in the model of nociception stress, many reactive oxygen species (ROS) were generated, which reduced the enzymatic defense mechanisms and activated lipid peroxidation mechanisms. Expand
Antioxidant action of a new flavonic derivative in acute carbon tetrachloride intoxication
TLDR
Results suggest that TR-1722 acts by curtailing both lipid peroxidation and alkylation processes, using CCl4 as a free radical generating model. Expand
[The involvement of vitamins C and E in changing the immune response].
TLDR
The results suggest that these vitamins with their known antioxidant properties may be used together with other immunomodulators for the adapting defence of organism. Expand
[The effect of the combination of vitamin E and C on the oxidative stress parameters in physical exercise].
TLDR
Malondialdehyde concentration revealed a slightly pro-oxidative behaviour of this couple of vitamins that explained the only partial recovery of enzymatic activity to normal values as well as a moderate lipid peroxidation process. Expand
Direct detection of the antioxidant activity of a new flavonic derivative using the chemiluminescence method.
TLDR
The results obtained reveal that theophylline rutoside (TR-1722) has antioxidant action comparable to that of quercetin, the highest efficacity being registered at the concentration of 2 mumol/l, the conditions being: H2O2 16,2 mmol/l; luminol 2 mumoled; Tris-HCl buffer 20 mmol/L, pH 8.3. Expand
