Animal and clinical studies were performed to establish a criterion for diagnosis of Fe-deficiency anemia and a standard dose of the i.v. Fe treatment, based on properties of serum transferrin (Tr) in Fe metabolism during gestation. 59Fe-labeled large molecular colloid Fe-solution (CSA[chondroitinsulfate]-Fe) was injected in pregnant rats: the Fe transferring to the fetuses originated from the mothers' serum Fe isolated from CSA-Fe. There was no difference of Fe supplying abilities of Tr across to maternal and fetal tissues of rat, in anemia in the latter stage of gestation (A) and in non-pregnant Fe-deficiency anemia (B), but there was significant difference in nature of Tr between rat and woman. There was no difference in 59Fe-uptake into the rat reticulocytes from Tr between A and B. In the clinical study, Fe utilization rate was correlated with serum Fe saturation rate both in A and B. CSA-Fe was clinically given for A and B according to the original formulas, and utility of the formulas were confirmed.
