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 aim of this study was to assess the radioprotective effects of sodium selenite on parotid glands in rats by ultrastructural analysis of acinar cells. Four experimental groups were assessed; control, irradiated, selenium, and selenium/irradiated. The sodium selenite dose was 0.5 mg/kg, administered intraperitoneally 24 h before irradiation in the head and neck region with a single 15-Gy dose...

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...

Echium amoenum is an Iranian indigenous medicinal plant. In this research the effect of hydroalchoholic extract of this plant on sodium-selenite induced cataract formation was evaluated. Fifty five white rat pups were selected and divided into six groups. In first group (control 1) no elements injected. Second group (control 2) was received normal saline on 11-18 postpartum. Hydroalchoholic ext...

Excess consumption of selenium (Se) accumulator plants can result in selenium intoxication. The objective of the study reported here was to compare the acute toxicosis caused by organic selenium (selenomethionine) found in plants with that caused by the supplemental, inorganic form of selenium (sodium selenite). Lambs were orally administered a single dose of selenium as either sodium selenite ...

Background: Portulaca oleracea (PO) plant, omega-3 fatty acids and combination of sodium selenite and vitamin E can limit negative impacts on testicular tissue and function which may be caused by compensating for defective insulin release, enhancing antioxidant status and decreasing in blood glucose levels. Materials and Methods: A total of 96 adult male Sprague Dawley (SD) rats (weighing appro...

Weiss, K. F. (Iowa State University, Ames), J. C. Ayres, and A. A. Kraft. Inhibitory action of selenite on Escherichia coli, Proteus vulgaris, and Salmonella thompson. J. Bacteriol. 90:857-862. 1965.-The resistance of three microorganisms, Escherichia coli (ISU-41), Proteus vulgaris (ISU-37c), and Salmonella thompson (ISU-86-2), to increasing concentrations of selenite was determined. E. coli w...

background: successful therapy of leishmaniasis depends on effective cellular immune response. we evaluated the effectiveness of sodium selenite and zinc sulphate as known immunomodulator materials, in combination with glucantime® in treatment of cutaneous leishmaniasis lesions resulting from leishmania ma­jor in susceptible animal model. methods: thirty three female mice weighing 18-20 g at th...

Sodium selenite is a trace element essential for many physiological functions in the body. It is involved in various biological processes; it acts as a cofactor for antioxidant enzymes that protect against free radicals and is reported to limit metal-mediated oxidative DNA damage. In the present study, we investigated the effect of sodium selenite on neomycin ototoxicity in wild-type and transg...

This study was carried out to investigate the preventive effects of galactoglucomannan (GGM), a homogeneous polysaccharide from Dendrobium huoshanense, on liver injury and fibrosis induced by sodium selenite. Sprague-Dawley rats injected subcutaneously with sodium selenite at the dosage of 3.28 mgkg(-1) b.wt. were set as the model groups. Rats treated with sodium selenite at the dosage of 3.28 ...
