Cobalt (Co) is an essential trace element and its accumulation affects the concentrations of other elements. Co(II) is shown to compete with iron (Fe) for the transferrin receptor and to form a stable complex with hemoglobin thus affecting hematopoiesis. There are lack of data regarding the effect of chronic exposure to Co compounds and Fe content in spleen and liver of mice. The study investigates the effect of long-term treatment with cobalt-EDTA (Co-EDTA) on iron content in the spleen and liver of immature mice. Pregnant ICR mice were subjected to chronic treatment with daily dose of 75 mg/kg Co-EDTA which continued until d25 of the newborn pups. Results show accumulation of Co(II) in the organs of treated mice compared to age-matched controls. Fe content in the spleen and liver was affected as well. Significantly increased concentrations of Fe ions were measured in the livers of treated mice. The changes could explain impaired hematopoiesis and immune responses of exposed to Co(II) immature mice.

The structure of the title compound, tetrakis(2-amino-1,5-dihydro-1-methyl-4H-imidazol-4-one-N 3 )platinum(II) dithiocyanate, [Pt(C 4 H 7 N 3 O) 4 ](SCN) 2 , consists of [Pt(creat) 4 ] 2+ (creat is 2-imino-1-methyl-4-imidazolidinone) complex cations possessing approximate D 2 symmetry and thiocyanate anions. The Pt atom is coordinated in a square-planar manner by four creatinine ligands bonded through their endocyclic N atoms. The Pt-N bond distances range from 1.980(6) to 2.034(7)A. The creatinine molecules are planar and participate in inter- and intramolecular hydrogen bonds. The ligands are almost perpendicular to the equatorial PtN 4 plane.
