The reactions of steroid hormone biosynthesis are accompanied by formation of oxygen radicals. We determined the levels of some antioxidants and antioxidative enzymes at different developmental stages of bovine corpora lutea to examine their correlation with steroidogenic status. Plasma progesterone concentrations of estrous cycle synchronized cows increased until day 16, and then decreased rap...
BACKGROUND Silver fir trunk extract (SFTE) is a complex mixture of antioxidative polyphenols (lignans and phenolic acids) from the trunks of silver fir trees (Abies alba, lignum). In our previous study, we have shown that SFTE exerts strong antioxidative and protective effects against atherogenic, diet-induced arterial wall damage. OBJECTIVE The aim of the present study was to test the potent...
Nine compounds, 3-hydroxy-4,5-dimethoxyphenyl-beta-D-glucopyranoside (1), beta-D-fructfuranosyl-alpha-D-(6-vanilloyl)-glucopyranoside (2), beta-D-fructfuranosyl-alpha-D-(6-syringyl)-glucopyranoside (3), 3-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-2-[4-(3-hydroxy-1-(E)-propenyl)-2-methoxyphenoxy]propyl-beta-D-glucopyranoside (4), 3-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-2-[4-(3-hydroxy-1-(E)-propenyl...
Tea is a beverage consumed widely throughout the world. The existence in tea of chemopreventing compounds possessing antimutagenic, anticarcinogenic and antioxidative properties has been reported. High intakes of tea and foods containing flavonoids have recently been shown to be negatively correlated to the occurrence of CHD. However, tea may contain other compounds with similar activities. Usi...
The aim of the study was to determine the activity of antioxidative enzymes GPH-Px and SOD as well as selenium concentration and distribution in mice treated with selenium compounds. Organic selenium compounds obtained in our laboratory: 4-(o-tolyl-) selenosemicarbazide of p-chlorobenzoicacid and 3-(p-chlorobenzoylamino-)-2-(o-tolylimino-) 4-phenyl-4-selenazoline were administrated to mice in a...
The objective of the present study was to investigate the beneficial properties lignan compounds obtained from the fruits of Forsythia suspensa (Thunb.) Vahl (Oleaceae) for protecting human high-density lipoprotein (HDL) against lipid peroxidation. The isolated compounds (1-8) inhibited the generation of thiobarbituric acid-reactive substances (TBARS) in a dose-dependent manner with IC50 values...
Many dietary compounds are known to have health benefits owing to their antioxidative and anti-inflammatory properties. To determine the molecular mechanism of these food-derived compounds, we analyzed their effect on various genes related to cell apoptosis, DNA damage and repair, oxidation and inflammation using in vitro cell culture assays. This review further tests the hypothesis proposed pr...
