Clinical InformationClinical

  • Hemosiderosis

    conditions in which there is a generalized increase in the iron stores of body tissues, particularly of liver and the mononuclear phagocyte system, without demonstrable tissue damage. the name refers to the presence of stainable iron in the tissue in the form of hemosiderin.

  • Hemosiderosis, Pulmonary

    iron deposition within the lung. primary pulmonary hemosiderosis is characterized by hemoptysis; iron-deficiency anemia, and diffuse pulmonary hemorrhage as seen as transient pulmonary infiltrates on radiography. even though large amounts of iron are laid down in the lung, with normal or increased total body iron, anemia occurs because of inability of the erythron to use iron sequestered in pulmonary macrophages.

  • Iron Overload

    an excessive accumulation of iron in the body due to a greater than normal absorption of iron from the gastrointestinal tract or from parenteral injection. this may arise from idiopathic hemochromatosis, excessive iron intake, chronic alcoholism, certain types of refractory anemia, or transfusional hemosiderosis. (from churchill's illustrated medical dictionary, 1989)

  • Mononuclear Phagocyte System

    mononuclear cells with pronounced phagocytic ability that are distributed extensively in lymphoid and other organs. it includes macrophages and their precursors; phagocytes; kupffer cells; histiocytes; dendritic cells; langerhans cells; and microglia. the term mononuclear phagocyte system has replaced the former reticuloendothelial system, which also included less active phagocytic cells such as fibroblasts and endothelial cells. (from illustrated dictionary of immunology, 2d ed.)

Patient EducationClinical

Metabolic Disorders

Metabolism is the process your body uses to get or make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Chemicals in your digestive system break the food parts down into sugars and acids, your body's fuel.
