OSTI ID:4306890
In a series of three tests the metabolism of/sup 75/ Se was studied as well as the effect of addition of different levels of vitamin E and selenium dioxide on the same. In the chickens 4 millicurie /sup 75/Se/kg live weight was administered orally in the form of Na/sub 2/SeO/sub 3/ and blood was taken from the wing vein at predetermined intervals. The liver, kidneys, pancreas, muscles, brain, spleen, testis, and bones were investigated for radioactivity. The amount of /sup 75/Se excreted in the feces and urine was investigated in the 24th, 48th, and 72nd hour after the administration of radioselenium. The resomption of radioselenium in the alimentary system of the chickens was most intensive between the 4th and 7th hour, after which it decreased. The highest rate of /sup 75/Se accumulation was observed in the liver and kidneys between the 2nd and 4th and between the 5th and 7th hour respectively. The highest radioactivity was observed in the muscles. The addition of 20, 60, and 200 IU Vitamin E to the basic ration did not cause noticeable alteration of the radioactivity of the blood, the organs investigated and of the excreted /sup 75/Se with the feces and urine as compared to the control group. The blood radioactivity decreased with the increase of the amount of selenium in the basic ration, as its lowest level was observed in the group with highest dose of selenium dioxide (6 mg/kg fodder).
