This trial describes the effect of intraruminal infusion of sodium selenite on the in-sacco rumen degradability of a legume, Centrosema pubescens and a grass, Pennisetum purpereum in West African dwarf (WAD) sheep. A total of sixteen WAD sheep of an average body weight, 16.19 ± 2.63 kg were used for this study. A 4 x 4 Latin square design of four sheep and four sodium selenite treatments (doses...

In a recent issue of the Journal, Taylor et al. (1) argued that selenium appears to play an important role not only in preventing various cancers but also in some degenerative diseases. Most of the data on the cancer prevention and cancer reduction effects of selenium are derived from epidemiologic studies (2). However, despite strong evidence for the importance of selenium in carcinogenesis, v...

This article presents the results of therapeutic efficacy in application sodium selenite antioxidant drug and sorbent additive montmorillonite their influence on nonspecific resistance reproductive functions cows. The prevalence gynecological diseases farm, including retention afterbirths non-infectious origin, with relative well-being conditions feeding housing, was reason for search methods p...

Sodium selenite and sodium selenate are approved inorganic Se (selenium) compounds in human and animal nutrition serving as precursors for selenoprotein synthesis. In recent years, numerous additional biological effects over and above their functions in selenoproteins have been reported. For greater insight into these effects, our present study examined the influence of selenite and selenate on...

The effects of selenium exposure were studied in LNCaP human prostate cancer cells, and this same cell line adapted to selenium over 6 months to compare acute versus chronic effects of sodium selenite, the latter most closely resembling human clinical trials on the effects of selenium in cancer prevention and therapy. Our results demonstrated that oxidative stress was induced by sodium selenite...

Two chelating agents meso-2,3-dimercaptosuccinic acid (DMSA) and sodium 2,3-dimercapto-propane-1-sulphonate (DMPS) were tested for their efficiency in mercury removal from the body of rats in the presence and in the absence of selenium. Female Wistar rats were given a single intraperitoneal injection of mercuric chloride or an equimolar mixture of mercuric chloride and sodium selenite (1.5 micr...

This study investigated bioreduction of selenite by anaerobic granular sludge in the presence of heavy metals and analyzed the fate of the bioreduced selenium and the heavy metals. Selenite bioreduction was not significantly inhibited in the presence of Pb(II) and Zn(II). More than 92% of 79 mg/L selenite was removed by bioreduction even in the presence of 150 mg/L of Pb(II) or 400mg/L of Zn(II...

Isotope dilution analysis of the sub-microg l(-1) levels of selenite and selenate in natural water samples by microwave-induced nitrogen plasma mass spectrometry (MIP-MS) was performed. An appropriate amount of a spike solution containing 78Se-selenite and 78Se-selenate was added to the natural water sample to be analyzed. Both analytes in the water were then concentrated simultaneously by pass...

Selenium (Se) is an essential element for many organisms but also toxic at higher levels. The objective of this study was to identify accessions from the model species Arabidopsis thaliana that differ in Se tolerance and accumulation. Nineteen Arabidopsis accessions were grown from seed on agar medium with or without selenate (50 microM) or selenite (20 microM), followed by analysis of Se toler...
