Analysis of serum iron indexes was performed as described in Materials and Methods. Monocyte Ft was measured by a radioimmunoassay based on an antihuman liver Ft antibody. IRP activity was determined by liquid scintillation counting of regions of the gels corresponding to the IRE/IRP complexes as reported in Materials and Methods. All values represent mean ± SD.
