Glutatione peroxidase in bovine semen.
The roles ofselenium (Se) and glutathione peroxidase in reproductive function are poorly understood, but it is possible that they may be important for normal reproduction in the male. In rats fed a Se-deficient diet, the testes accumulated and retained more 75Se than did other tissues 1 week after injection (Brown & Burk, 1972; Burk, Brown, Seely & Scaief, 1972). Autoradiographic studies (Brown...
متن کاملProtective role of glutathione in buck semen cryopreservation
The aim of this study was to determine the effect of low levels of glutathione on post-thawed buck sperm quality. In this experiment, different concentrations of glutathione [0 (LG-0), 0.5 (LG-0.5), 1 (LG-1), 1.5 (LG-1.5), and 2 (LG-2) mM] were added in a soybean lecithin-based extender. A total of 16 ejaculates from four bucks were collected and pooled. Each pooled sample was divided into five...
متن کاملSuperoxide dismutase and glutathione peroxidase activities in bovine placenta : spectrophotometric and electrophoretic analysis
Reactive oxygen species are unavoidable products of metabolism and in excess they can be dangerous for tissues and cells. Superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), among others, protect tissues and cells against reactive oxygen species. The aim of the study was the description of SOD and GSH-Px from bovine placenta by use of spectrophotometric and electrophoretic analysis ...
متن کاملGlutathione Peroxidase Potentiates the Inhibition
GSH peroxidase (Px) catalyzes the reduction of lipid hydroperoxides (LOOH), known metabolic products of platelets and vascular cells. Because interactions between these cells are modulated by nitric oxide (NO) and LOOH inactivate NO, we investigated the effect of GSH-Px on the inhibition of platelet function by the naturally occurring S-nitrosothiol, S-nitroso-glutathione (SNO-Glu). Concentrati...
متن کاملPlasma glutathione peroxidase in pediatric stroke families.
BACKGROUND/OBJECTIVES Promoter polymorphisms in the plasma glutathione peroxidase gene (GPX3), which encodes a major antioxidant enzyme implicated in post-translational modification of fibrinogen, have been implicated as risk factors for arterial ischemic stroke (AIS) and cerebral sinovenous thrombosis (CSVT) in young adults. However, the contribution of these polymorphisms could not be confirm...
