sodium valproate and tomato extract have been studied in different experimental models of epilepsy individually. the aim of the present study was to evaluate the effect of lycopene on the antiepileptic effects of sodium valproate against pentylenetetrazol-induced kindling in mice. swiss albino mice of either sex were randomly divided into 5 groups, with each group containing 8 mice. these group...

The goal of this work was the research chondroitin sulfate prophylactic action on glutathione system state in rat blood serum during acute joint inflammation. performed white non-linear pubertal males weighting 160-240 grams compliance to all general ethical principles animal research. All animals were divided four experimental groups. first group – control: injected with 0,1 ml 0,9 % NaCl solu...

Chitosan membrane with glutathione reductase and sulfhydryl oxidase (SOX) was subsequently integrated onto the surface of spectrographic graphite rods for obtaining a glutathione biosensor. The working principle was based on the monitoring of O(2) consumption that correlates the concentration of glutathione during the enzymatic reaction. A linear relationship between sensor response and concent...

To find out whether systemic glutathione deficiency is associated with human immunodeficiency virus (HIV) infection, thus contributing to the immunodeficiency state, glutathione concentrations in venous plasma and lung epithelial lining fluid (ELF) of symptom-free HIV-seropositive and normal individuals were measured. Total and reduced glutathione concentrations in the plasma of the HIV-infecte...

Glutathione peroxidase was extracted from calf trabecular meshwork. The kinetics of this enzyme were examined, varying the substrates hydrogen peroxide (H2O2), tert- butylhydroperoxide ( tBHP ), and glutathione. The activity of the enzyme in nonpurified homogenates was 596 nmole H2O2 reduced/min/gm wet weight and 680 nmole tBHP reduced/min/gm wet weight (27-28 nmole peroxide reduced/min/mg prot...

1. Erythrocytes (RBC) from control and marginally riboflavin-deficient subjects were fractionated into nine fractions using a discrete density gradient. 2. Glutathione reductase (NAD(P)H: glutathione oxidoreductase; EC 1.6.4.2) activity and aspartate aminotransferase (EC 2.6.1.1) activity (with and without the appropriate co-enzymes) reduced glutathione, methaemoglobin, sulphaemoglobin and oxy...

We detected no difference in the reduced glutathione content of erythrocytes obtained from patients with rheumatoid arthritis (RA) and controls. The stability of glutathione to oxidative stress (cumene hydroperoxide) was also the same. Although measured in the erythrocyte, our results indicate that changes in intracellular reduced glutathione are not involved in the aetiology of RA. Serum from ...

Changes in telomerase activity have been associated either with cancer, when activity is increased, or with cell cycle arrest when it is decreased. We report that glutathione, a physiological antioxidant present at high intracellular concentrations, regulates telomerase activity in cells in culture. Telomerase activity increases in 3T3 fibroblasts before exponential cell growth. The peak of tel...

Reduced glutathione (GSH) and Glutathione S-transferase (GST) play important roles in the detoxification of several xenobiotic compounds, including pesticides. This study was carried out to access the effect of the organophosphate pesticide, dichlorvos on the activities of GSH, GST as well as lipid peroxidation of egg laying hens. Seven weeks old pullets weighing between 400-600 g divided into ...
