Abstract: | The influence of selenium on the disposition of nickel and on Ni induced metallothionein levels was studied in female rats. Concomitant administration of Se (6.3 mumol/kg, intraperitoneally) and 63Ni (0.12 mmol/kg subcutaneously) lowered the Ni burden of all the soft organs and the plasma ceruloplasmin levels. Selenium caused no potentiating effect on the Ni induced hepatic MT. However, 3 days later, the lowered MT levels appeared related to the corresponding decrease in hepatic Ni content at day 6. The Ni selenide excretable complex and Ni-selenide protein complex appear to be probable mechanisms of the Ni-Se interaction in the present study. |
