    The role of ferritin in iron absorption
    (1967-01) Torrance, J. D.
    Although reports of the medicinal use of iron date back to ancient times it was not until the present century that the many functions of iron in the body were studied. Once started, the investigation received impetus from the seriousness of iron deficiency anaemia, a major cause of ill health throughout the world. The introduction of radio-isotope tracer techniques in 1939 greatly facilitated investigation of absorption, excretion and the metabolic pathways of iron. The tremendous amount of work already carried out has led to a fairly comprehensive knowledge of the various aspects of iron metabolism. Nevertheless, there remain wide gaps in the overall picture.

    The relationship between iron nutrition and the factors present in vegetable and cereal foods that affect iron absorption
    (1986) Gillooly, Mary . A.
    The iron nutrition of populations is largely determined by the quality of the diet consumed. As this is frequently cereal or vegetable based, the interplay of the different enhancers and inhibitors that influence iron absorption from the "common pool" of non-haem iron assumes a profound significance in iron nutrition. This thesis took advantage of the widespread occurrence of iron deficiency among Indian women in Natal to establish more clearly the factors in frequently consumed foods which affect iron absorption.

    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.

    Some physiological aspects of iron transport - studies on the fortification of sugar with iron
    (1976) Disler, Peter, Barry
    An attempt was made to fortify sugar with iron in order to prevent the development of iron deficiency. It was possible to add various iron salts and ascorbic acid to sugar without discolouring the vehicle even after storage for many months under hot humid conditions. The absorption of iron from fortified sugar and cereal meals was then measured in human volunteers using either an "extrinsic tag" to label the iron compound or intrinsically labelled food iron.

    Aspects of iron metabolism - factors affecting iron absorption
    (1983) Bezwoda, Werner, Robert
    The investigations which make up the body of this thesis touch on various aspects of iron absorption. Although many of the factors governing iron absorption have been elucidated specific problems remain to be defined in greater detail. The aim of these investigations was therefore to define more fully some of the quantitative and qualitative aspects of dietary iron absorption
