Abstract:
15 rat dams were divided into 2 groups: selenium treated group drank water containing 2 ppm selenium during pregnancy and breast-feeding period, control group drank tap water. The concentration of selenium in brain tissue for dams were 0.73 ?0.11 (Se-treated) and 0.54 ?0.09 ug/g wet tissue (control), for neonates 0.32?0.02 (Se-treated) and 0.25 ? 0.03 (control), and for 20 days old pups 0.53?0.04 (Se-treated) and 0.44?0.06 (control). The results showed that the selenium administered orally could be transfered through placenta or blood-brain barrier of fetus, young pup and adult rat.
