This study was designed to determine the effect of diphenyl diselenide and ebselen, synthetic organoselenium compounds with antioxidant properties, in diabetic rats. Diabetes was induced by the administration of streptozotocin (STZ) (45mg/kg, intravenous). In experimental trials, diphenyl diselenide, but not ebselen, caused a significant reduction in blood(More)
Selenium compounds, like diphenyl diselenide (Ph(2)Se(2)), possess glutathione peroxidase (GSHPx)-like activities and other antioxidant properties. The aim of this study was to evaluate the effects of a long-term oral supplementation with Ph(2)Se(2) on various toxicological parameters in rabbits. Adult New Zealand male rabbits were divided into four groups:(More)
Recently, we have described the beneficial effects of Diphenyl diselenide, an organochalcogen with glutathione peroxidase-like activity, on reserpine-induced orofacial dyskinesia in old rats. In this study, our aim was to examine the effects of diselenide on haloperidol-induced orofacial dyskinesia in rats. Male wistar rats received one single dose of(More)
The concept that selenium-containing molecules may be better antioxidants than classical antioxidants, has led to the design of synthetic organoselenium compounds. The present study was conducted to evaluate the potential toxicity of long time oral exposure to diphenyl diselenide (PhSe)2 in rabbits. Male adult New Zealand rabbits were divided into four(More)
This paper evaluates the ability of organoselenium compounds [ebselen, selenocystine N-ethyl-carbamate (SeCis), bis-4-isopropyl-2-oxazolinyl phenyl diselenide (AASe)] to prevent HgCl(2) toxicity. Rats were injected with HgCl(2) (0 or 17 micromol/kg, sc) 6 h after organoselenium compounds had been injected (0 or 50 micromol/kg, sc). In vivo, HgCl(2)(More)
It is known that lead is toxic to several species of animals, and growing data support the participation of oxidative in lead toxicity. Selenium compounds, like diphenyl diselenide and Ebselen have a thiol-peroxidase like and other antioxidant properties. In this work, we determine whether these non-thiol-containing compounds with antioxidant properties(More)
This study evaluated the effect of possible synergic interaction between high fat diet (HF) and hydrochlorothiazide (HCTZ) on biochemical parameters of oxidative stress in brain. Rats were fed for 16 weeks with a control diet or with an HF, both supplemented with different doses of HCTZ (0.4, 1.0, and 4.0 g kg(-1) of diet). HF associated with HCTZ caused a(More)
The present study evaluates the effects of Na(2)SeO(3) and HgCl(2) on kidney and liver of adult rats. In vivo, HgCl(2) (17 micromol/kg, sc) reduced ascorbic acid levels in liver ( approximately 15%), whereas in kidney it reduced ALA-D activity ( approximately 60%) and ascorbic acid levels ( approximately 35%) and increased TBARS content ( approximately(More)
Changes in sulfhydryl status have been shown to be involved with the ethanol-induced hepatotoxicity. In addition, evidence shows the importance of replenishing thiols in patients with alcoholic liver disease. This study was undertaken to examine the possible beneficial effects of the individual and simultaneous treatments with two antioxidant drugs(More)
The aim of this study was to investigate the effects caused by subchronic exposure to diphenyl diselenide in rats. Adult Wistar rats were exposed to diphenyl diselenide (5-300 micromol kg(-1), subcutaneously) once a day for 14 days. The subchronic administration of diphenyl diselenide at a dose of 300 micromol kg(-1) significantly increased aspartate(More)
