reticuloendothelial

[rĕ-tik″u-lo-en″do-the´le-al]

pertaining to the reticuloendothelium or to the reticuloendothelial system.

reticuloendothelial system a network of cells and tissues found throughout the body, especially in the blood, general connective tissue, spleen, liver, lungs, bone marrow, and lymph nodes. They have both endothelial and reticular attributes and the ability to take up colloidal dye particles. Some of the reticuloendothelial cells found in the blood and in the general connective tissue are unusually large in size. These cells are concerned with blood cell formation and destruction, storage of fatty materials, and metabolism of iron and pigment, and they play a role in inflammation and immunity. Some of the cells are motile—that is, capable of spontaneous motion—and phagocytic—they can ingest and destroy unwanted foreign material.

The reticuloendothelial cells of the spleen possess the ability to dispose of disintegrated erythrocytes. They do not, however, destroy hemoglobin, which is liberated in the process.

The reticuloendothelial cells located in the blood cavities of the liver are called Kupffer cells. These cells, together with the cells of the general connective tissue and bone marrow, are capable of transforming into bile pigment the hemoglobin released by disintegrated erythrocytes.

Tf incorporates iron coming from two major sources: dietary iron (both inorganic and heme iron) absorbed in the duodenum to compensate for daily iron loss and iron derived from destruction of old and effete erythrocytes by reticuloendothelial cells in the spleen and liver (Figure 3).

Pseudomonas aeruginosa is a predominant pathogen associated with chronic pulmonary infection and mortality in CF.[sup.17] Extrapulmonary spread of infection is quite rare, likely owing to enhanced immune complex formation and reticuloendothelial clearance in CF patients.[sup.3,4] However, there have been case reports of extrapulmonary spread of Pseudomonas aeruginosa in immunocompetent CF patients chronically infected with the mucoid strain of this organism with bacteremia, endopthalmitis and pericarditis.[sup.18]-[sup.21] In most cases, patients had poor outcomes, ranging from enucleation to death, despite prompt diagnosis and treatment for their extrapulmonary infections.
