Objectives. The aim of the present study was to investigate the protective role of selenium against cisplatininduced oral mucositis in rats. Methods. Healthy wistar albino rats (n=21) were randomly divided into three groups: Cisplatin (Cis), cisplatin and selenium (Cis+Se) and control (C). Cisplatin was administered for 3 days to Cis and Cis+Se groups. Cis+Se group received selenium 5 days befo...

For 8 wk 5 groups of 10 men each were given 0.5 g/day DL-methionine, 150 micrograms Se/day as sodium selenite with or without methionine or 150 micrograms Se/day as selenomethionine with or without methionine. Twenty subjects received placebo as controls. Initially plasma Se rose more rapidly than RBC Se. Increases in Se levels were significantly greater with selenomethionine than with the sele...

An experiment was conducted in order to evaluate the effects of Se spraying on yield and growth indices of wheat under drought stress condition, in agriculture and natural resource research center of Tehran province in 2011-12. A split plot layout within randomized complete block design with three replications were used. main plots were three irrigation treatments (normal irrigation, non-irriga...

Selenium is an essential trace mineral that is required for many physiological functions in animals and the potential relevance of selenium to the reproductive system of livestock has been considered by many researchers. The objective of this study was to examine the effect of selenium supplementation on the spermatogenic cells of goat. Eight young male crossbred (Katjang x Boer) goats, aged be...

the objective of this study was to determine the effects of supplemented selenium (se) on plasma cortisol, red blood cell glutathione peroxidase activity (rbc gsh-px-1), concentration of immunoglobulin g (igg) and body weight in pneumonic suckling calves. ten holstein suckling male calves were randomly allocated to two groups and fed either unsupplemented milk (control) or with milk supplemente...

The goal of the experiment was to compare the effect of four different forms of selenium (Se) − sodium selenite (SS), lactate-protein selenium complex (SL), selenium enriched yeast (SY), and seleniumproteinate (SP) supplemented to pregnant goats on Se concentration and glutathione peroxidase (GSH-Px) activity in the blood of goats on the day of delivery and also on Se concentration and GSH-Px a...

Selenium is an essential element for humans, animals and some species of microorganisms. The biological function of selenium shows dual characteristics. The selenium content range between toxic and deficient concentration is very narrow. The present paper discusses the geographical distribution of two forms (total and water-soluble) of selenium in topsoil (plough layer for cultivated soils, elu...

For more than sixty years lithium carbonate has been used in medicine. However, during its administration different side effects including oxidative stress can occur. Selenium belongs to essential elements possessing antioxidant properties. This study aimed at evaluating if selenium could be used as a protective adjuvant in lithium therapy. The experiment was performed on four groups of Wistar ...

Introduction Selenium (Se) is a group VI element with chemical properties very similar to those of sulfur, it has been demonstrated as an essential element for ruminants. Selenium is required to prevent deficiency diseases such as white muscle disease, maintain growth rates of young animals and promote reproductive performance. Camel sensitivity to trace element imbalances has been reported (Fa...

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...
