Item Iron storage in the neonatal period of the human infant(1950) Van Dongen, L. G. R.Iron is one of the vital elements of the human body. Without it respiration would be quite impossible. Haemoglobin, the transporter of oxygen throughout the body, has iron as an essential constituent, and it is in this protein complex that the greatest bulk of the metal is found. Iron also plays a very essential part in the respiration of the tissues, as it is a vital element in intracellular respiratory enzymes such as catalase, cytochrome, cytochrome oxidase, etc. Further it is found in the chromatin material of nuclei in the cells of all the tissues.Item Radioiron absorption studies in idiopathic haemochromatosis, malnutritional cytosiderosis, and transfusional haemosiderosis(1953-05) Bothwell, T. H.The quantity of iron in the body is regulated largely by the amount absorbed from the gut as the body's capacity to excrete it seems to be very limited. However three conditions have been described in which enormous amounts of iron may accumulate. Such a finding is characteristic of idiopathic haemochromatosis, it is present in a proportion of malnourished South African and is seen also in cases of refractory anaemia treated over long periods with blood transfusions.
