title: Ebselen attenuates cadmium-induced testicular damage in mice.
abstract: This study was designed to examine if ebselen, an organoselenium compound with antioxidant and glutathione peroxidase-mimetic properties, attenuates testicular injury caused by intraperitoneal administration of CdCl(2). A number of toxicological parameters were evaluated in the testes of mice, such as delta-aminolevulinic acid dehydratase (delta-ALA-D) activity, lipid peroxidation, ascorbic acid levels and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities. Ebselen attenuated lipid peroxidation levels altered by CdCl(2). delta-ALA-D activity inhibited by the highest dose of CdCl(2) was attenuated by ebselen. A significant negative correlation between lipid peroxidation levels and delta-ALA-D activity was observed. Ebselen restored ascorbic acid levels reduced by CdCl(2). A significant negative correlation between ascorbic acid levels and delta-ALA-D activity reinforces the idea that ebselen attenuated the damage induced by CdCl(2) via its antioxidant property. The significant correlation between ALT and delta-ALA-D activity supports the assumption that ebselen prevented damage caused by CdCl(2). The results show that ebselen attenuated oxidative stress, a process important for CdCl(2) toxicity.
