The balance of phagocytic function among Kupffer cells, hepatic endothelial cells and splenic macrophages in the chronically ethanol-fed rats has been investigated. Clearance of latex particles in the blood was measured to estimate the function of the reticuloendothelial system. Phagocytosis of latex particles by Kupffer cells, hepatic endothelial cells or splenic macrophages in vivo was measured by counting the number of ingested particles in a cell after isolation of hepatic nonparenchymal cells or spleen cells following injection of different amounts of latex particles. Latex particle clearance was suppressed in the ethanol-fed rats, demonstrating a decreased phagocytic capacity of the reticuloendothelial system. Markedly decreased phagocytic function was found in 40% of Kupffer cells of the chronically ethanol-fed rats. In contrast, the number of latex particles in hepatic endothelial cells and in splenic macrophages was increased after injection of a triggering dose of latex particles. From these results it may be concluded that an increased phagocytosis of hepatic endothelial cells and splenic macrophages could compensate for the decreased phagocytic function of Kupffer cells.

UI MeSH Term Description Entries
D007728 Kupffer Cells Specialized phagocytic cells of the MONONUCLEAR PHAGOCYTE SYSTEM found on the luminal surface of the hepatic sinusoids. They filter bacteria and small foreign proteins out of the blood and dispose of worn out red blood cells. Kupffer Cell,Cell, Kupffer,Cells, Kupffer
D007840 Latex A milky, product excreted from the latex canals of a variety of plant species that contain cauotchouc. Latex is composed of 25-35% caoutchouc, 60-75% water, 2% protein, 2% resin, 1.5% sugar & 1% ash. RUBBER is made by the removal of water from latex.(From Concise Encyclopedia Biochemistry and Molecular Biology, 3rd ed). Hevein proteins are responsible for LATEX HYPERSENSITIVITY. Latexes are used as inert vehicles to carry antibodies or antigens in LATEX FIXATION TESTS. Latices,Latice
D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008264 Macrophages The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.
