The first part of this study deals with well known as well as new data on normal iron metabolism. The second part will concern Genetic Haemochromatosis, a recessively transmitted disease principally determined by a gene located on the sixth chromosome near the A locus of HLA system: phenotypic expression of the gene, clinical features, iron overload assessment, mechanism of iron toxicity, pathogenesis of iron overload. The third part considers iron overload secondary to anaemias, to chronic alcoholic liver diseases, to porphyria cutanea tarda, to chronic haemodialysis... and their relation to the Genetic Haemochromatosis. Beyond what is already well established still lies a large number of questions with answers, at this stage, uncertain or incomplete.

Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...
Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
