[The metabolic interaction of cobalt and silver in the body during their combined action].

Mixtures of cobalt and silver in ratio (0.2:0.4), (0.2:0.2) and (0.2:0.1) mg/kg were once administrated intraperitoneally and intratracheally to white rats. Metabolism of the metals was studied. Combined exposure to metals appeared to influence greatly on their toxicokinetics. The co-action between metals appears during their absorption into the blood--the elevated peritoneal absorption of cobalt depresses that of silver. The reverse relationship is demonstrated during the intratracheal insertion. Such peculiarities of co-action exist during the further stages of metabolism.
