“…These findings suggest that GPx activity may be enhanced at relatively low Se concentrations in the diet, 1.0 ppm or less, and that the activity may be reduced following administration of a higher Se concentration in the diet, for example, 2.4 ppm Se. In the experiments previously reported, Se concentrations of diets administered to control rats were set extremely low 13,14,29,36) , and might have been insufficient for enhancing GPx activity, while the concentration in our study was 0.67 ppm in the basal diet, which might have been sufficient for enhancing GPx activity. In regard to the relationship between tissue Se concentration and GPx activity, hepatic GPx activity increased at the hepatic Se concentration of 2.5 ppm compared to that at 0.2 ppm levels 14) .…”

Recently, Yoshida et al reported that administration of diet including Se-enriched JRS at a Se concentration of 0.15 ppm increased hepatic GPx activity 36) .

Selenium-enriched Japanese Radish Sprouts Influence Glutathione Peroxidase and Glutathione S-Transferase in an Organ-specific Manner in Rats: Hidetoshi HAMA, et al. Department of Preventive Medicine, Shinshu University School of Medicine-Selenium-enriched Japanese radish s p r o u t s ( S e -e n r i c h e d J R S ) , i n w h i c h S emethylselenocysteine accounted for 80% of Se compounds, inhibited mammary tumorigenesis induced by 7,12-dimethylbenz[a]anthracene in rats. The effects of Se-enriched JRS on the oxidative stress-scavenging enzymes were investigated in rats. F344 female rats were fed test diets, in which Se-enriched JRS was added at 0, 2.4, 5.0, 8.8 or 12.5 ppm Se to commercial rodent chow for 3 wk. Glutathione peroxidase (GPx) and glutathione S-transferase (GST) in rat livers, kidneys and lungs were measured. Tissue Se concentrations at the highest Se dose (12.5 ppm) were high in order as follows: kidney > liver > lung. The diet at 12.5 ppm Se reduced the increase in body weight and, conversely, increased the liver weight. The Se test diets decreased hepatic and renal GPx activity at more than 2.4 ppm and 5.0 ppm, respectively. In contrast, the test diets increased pulmonary GPx activity at more than 2.4 ppm Se. The diets increased hepatic GST activity at more than 2.4 ppm Se dose dependently, whereas they reduced pulmonary GST activity at more than 2.4 ppm. The diet of 12.5 ppm Se induced GST Yp in all 3 organs and GST Yb1 in the liver. Thus, Se-enriched JRS influenced GPx and GST activity in a symmetrical manner in the livers and lungs of rats, with hepatic GST possibly affected, in part, by the induction of GST Yb1.

“…Various studies have confirmed that Se-enriched edible plants such as broccoli sprouts (Finley et al 2001), green onions (Kapolna & Fodor 2006), garlic (Tsuneyoshi et al 2006) or tritordeum (Tufarelli et al 2016b) can be successfully produced for human and animal nutrition. Additionally, these selenised plants have anticarcinogenic properties (Finley et al 2001;Yoshida et al 2007). Special freshwater selenium-enriched algae (genus Chlorella) represent another possible form of selenium addition to the diet (Skřivan 2009;Surai & Fisinin 2014).…”

In the last few years, interest in the supplementation of selenium (Se) to animal feed has increased. The results of various studies have shown that eggs with defined selenium content may be used as a new potential source of this scarce element in human nutrition. The selenium content in eggs after dietary supplementation in organic form is about 22-27 µg/egg. This amount represents up to 40-50% of the Recommended Dietary Allowance, which is 55 µg of Se for the adult human. Additionally, due to its antioxidant properties, selenium contributes to the oxidation stability of fat and protein in the eggs of laying hens fed a selenium-supplemented diet. Therefore, selenium addition can affect certain properties of eggs and improve their shelf life. The results of investigations into the physico-chemical properties of different forms of Se have proven that dietary supplementation in the organic form shows higher biological availability than inorganic selenium.

“…Selenium is also an element regulated by gene expression, and it participates directly in life activities. One third of the total selenium inside body exists in the form of selenium enzymes that fulfill essential functions such as preventing cell from lipids peroxidation, preserving the elasticity of blood vessels, and ensuring healthy brain and bone development (Yoshida et al 2007).…”

Selenium species in enriched garlic (Allium Sativum L) sprouts were determined by high-performance liquid chromatography coupled with inductively coupled plasma-mass spectrometry (HPLC-ICP-MS). The garlic was grown in a 10 mg/L selenite nutrient solution, and the total selenium accumulated by the sprouts was 250 lg/g. Three mobile phase systems were investigated and a buffer of 20 mmol/L ammonium acetate/5% methanol was chosen for subsequent analysis. Comparative experiments were performed to determine the selenium species in the garlic sprouts with four extraction solutions: 0.1 mol/L HCl, 0.1 mol/ L NaOH, 20 mmol/L ammonium acetate/5% methanol and protease XIV. The most suitable results were obtained using 0.1 mol/L HCl as the extracting solution. Validation was performed; all selenium compounds had recoveries of 102.5% to total selenium, with good linearity and precision. The major compound accumulated in the garlic sprouts was methylselenocysteine, which accounted for 65.01% of the selenium.
