THE DISTRIBUTION OF PARENTERAL IRON HAEMATINICS IN NONPREGNANT, PREGNANT AND LACTATING RATS.

The distribution of (59)Fe has been investigated in nonpregnant, pregnant and lactating rats and their young after injection of solutions containing a high molecular weight iron-dextrin complex (iron-dextrin, intravenously), and a low molecular weight complex of iron, sorbitol and citric acid (iron-sorbitol, intramuscularly), each labelled with (59)Fe. At different times after injection of a dose corresponding to 1.5 mg of iron per kg of body weight, the quantity of (59)Fe was determined in different organs, urine and carcass, and for pregnant rats also in foetuses and placentas.
