Abstract:
Bioavailability of selenium in Se enriched mushroom, Pleurstus ostreatus, was assayed with Se depleted rats. The selenium status in rats including blood, liver Se levels and erythrocyte glutathione peroxidase (GSH-Px) activity was evaluated. Young male SD rats were first fed with basal Se deficient diet for 4 weeks, followed by either continued depletion or repletion for another 3 weeks with 0.51, 0.75, 1.91, 3.18?g Se as sodium selenite, and 0.45, 0.72, 1.59, 3.41?g Se as Se enriched mushrooms per gram of diet for each group of rats respectively. Both Se levels in blood and in liver and erythrocyte GSH-Px activity were enhanced significantly with the increasing dietary Se contents. The relative bioavailability of selenium (taken selenite as 100%) in the Se enriched mushroom (P.ostreatus) was 66.66% based on the criteria of blood Se level, or 125.0% of liver Se level, or 123.42% of erythrocyte GSH-Px activity respectively. These results demonstrated that Se enriched mushroom (P.ostreatus) was an excellent dietary Se source.
