The effects of hypoxia of different durations (8, 12 or 15 min) and of subsequent reoxygenation were studied in rat hippocampal slices by measuring enzyme activities related to oxidative stress: superoxide dismutase (SOD), cytochrome c oxidase and lactate dehydrogenase (LDH). Simultaneously the degree of lipid peroxidation was estimated by measuring(More)
1. In nonanesthetized rabbits temporal occlusion of the abdominal aorta was used to induce oxidative stress in the lower part of the body including distal segments of the spinal cord. 2. Spinal cord samples were taken from the animals exposed to 25-min aortic occlusion (AO) or to occlusion followed by 1- or 2-hr reperfusion (AO/R1 or AO/R2, respectively) or(More)
The effect of two natural standardized plant extracts, Pycnogenol(®) and EGb 761, on sarcoplasmic reticulum Ca(2+)-ATPase (SERCA) activity and posttranslational modifications induced by peroxynitrite was investigated to assess their possible protective role. EGb 761 was found to have a protective effect on SERCA activity in the concentration range of 5-40(More)
OBJECTIVES Effects of phenolic antioxidants, synthetized (trolox, pyridoindole stobadine) and plant extracts (EGb 761 and Pycnogenol) were investigated on the activity of Ca(2+)-ATPase from sarcoplasmic reticulum (SR) of rabbit skeletal muscle to examine their potency to modulate the activity of this calcium level regulating enzyme. METHODS SR vesicles(More)
