The effects of bicarbonate and its combination with the chelating agents, deferiprone (L1), 4,6-dimethyl-1-hydroxypyrimidin-2(1H)-one (AK-4), catechol-3,6-bis(methyleneimino-diacetic-acid) (CBMIDA), and ethane-1-hydroxy-1,1-bisphoshonate (EHBP) in removing depleted uranium (DU) for radiation emergency medicine were examined. After the intramuscular injection of DU in rats, various time schedules of bicarbonate and chelating agent administration were tested. The results indicate that the bicarbonate helps increase significantly the effects of LI and AK-4, while there were no effects of using bicarbonate alone. The effects of bicarbonate on CBMIDA were unclear, and the effects of EHBP were negative. Further studies are necessary to obtain distinctly synergic effects by the combination of chelating agents with bicarbonate.
