    • AIM: The present study was designed to investigate a complex of oxidative stress (OS) markers in patients with chronic renal failure (CRF) and to study the relationship between different OS markers and degree of renal failure. The following indices of OS were measured in plasma: oxidized glutathione (GSSG), reduced glutathione (GSH), total glutathione (TGSH), glutathione redox ratio (GSSG/GSH) and resistance of lipoprotein fraction to oxidation (lag phase of LPF). Baseline diene conjugation level of lipoprotein fraction (BDC-LPF), total antioxidative activity (TAA), diene conjugates (DC), lipid hydroperoxides (LOOH) and thiobarbituric acid-reactive substances (TBARS) were measured in serum. All markers in plasma and serum were measured both in patients with CRF and in healthy controls. SUBJECTS AND METHODS: Blood samples were obtained from 38 patients with CRF and from 61 healthy controls. Routine biochemical analyses were performed by using commercially available kits. RESULTS: Levels of DC, BDC-LPF, LOOH, GSSG and GSSG/GSH ratio were significantly increased and lag phase of LPF was significantly shortened in patients with CRF compared with healthy controls. Serum creatinine and urea levels correlated significantly with GSSG level and GSSG/GSH in patients with CRF. A significant inverse correlation was found between glutathione redox ratio and lag phase of LPF and between GSSG level and BDC-LPF. CONCLUSIONS: The findings suggest that renal patients are in a state of oxidative stress compared with healthy controls. The most informative indices to evaluate the degree of OS in CRF were: GSSG level, GSSG/GSH status, lag phase of LPF and BDC-LPF.

    • To evaluate the level of oxidative stress (OS) in familial Alzheimer’s disease (FAD), we analysed four cerebrocortical areas from patients with Swedish FAD bearing the APP670/671 mutation. The temporal inferior cortex (TIC) from Swedish FAD patients revealed a striking 2- to 3-fold increase in diene conjugates, lipid peroxides and protein carbonyls, compared to sporadic Alzheimer’s disease (AD). Compared with TIC from sporadic AD patients, the mutation carriers showed a markedly decreased activity of catalase (CAT) in the same area, and the same trend was found for another antioxidant enzyme, superoxide dismutase. These results are consistent with the deep oxidative injury of TIC in Swedish FAD. In the frontal inferior cortex (FIC), sensory postcentral cortex (SPCC) and occipital primary cortex (OPC) from Swedish FAD, the parameters of oxidative injury tended to be higher than in sporadic AD. Only the increase in the levels of lipid hydroperoxides in SPCC and of protein carbonyls in OPC was significant. Compared to sporadic AD, Swedish FAD showed a significant increase in GSSG levels and the GSSG/2GSH ratio in the FIC, SPCC and OPC. A significantly decreased activity of CAT was detectable for the SPCC and OPC in Swedish FAD. Increased OS might play a crucial role in the rapid progression of Swedish FAD from the associative temporal cortex to the primary cerebrocortical areas.
