Antioxidative enzyme activities in human erythrocytes.

Reliable and standardized methods are necessary to determine the expression of antioxidative enzymes and their role in maintaining health. In addition, the variability of the enzyme activities within the general population caused by age, gender, and life-style factors must be described. This study describes methodological conditions that are suitable for analyzing copper-zinc superoxide dismuta...

Mitochondrial respiratory and antioxidative enzyme activities in turkey meat.

Meat quality and (anti)oxidative metabolism of m. pectoralis superficialis (MPS), m. gastrocnemius (MG) and m. iliotibilialis lateralis (MIL) from turkey toms were analysed. After slaughter, pH of MPS and MG decreased and electrical conductivity of the MPS increased. The MG had generally higher pH values. The meat lightness (L) and redness (a) increased in MG and MPS after slaughter. The MPS al...

Effect of atypical antipsychotics on antioxidant enzyme activities in human erythrocytes (in vitro study).

OBJECTIVE This study was set out to examine the impact of atypical antipsychotic drugs: aripiprazole, clozapine, ziprasidone, olanzapine, quetiapine, sertindole and amisulpride on the activity of antioxidant defence enzymes in human erythrocytes in vitro. METHODS Cu,Zn-superoxide dismutase (SOD1), catalase (CAT), selenium-dependent glutathione peroxidase and glutathione reductase activities w...

Age-correlated modifications of copper-zinc superoxide dismutase and glutathione-related enzyme activities in human erythrocytes.

To obtain a comprehensive profile of the erythrocyte antioxidant defense potential during aging, we investigated copper-zinc superoxide dismutase (CuZn-SOD), seleno-dependent glutathione peroxidase (GSH-Px), glutathione reductase (GSSG-RD), and glutathione-S-transferase (GSH-S-T) activities in human erythrocytes from 167 apparently healthy subjects, ages one month to 63 years (102 females, 65 m...

Lipid peroxidation and antioxidative enzyme activity in erythrocytes of workers occupationally exposed to aluminium.

Current research indicates that lipid peroxidation could have a role in aluminium toxicity. The aim of this study was to asses lipid peroxidation and antioxidative enzyme activity in erythrocytes of workers occupationally exposed to aluminium. We investigated a group of 59 workers (Al group) exposed to aluminium fumes (contamination factor F=8.07 to 13.47, national maximal allowed concentration...
