| continuous ambulatory peritoneal dialysis | Method of peritoneal dialysis performed in ambulatory patients with influx and efflux of dialysate during normal activities. (05 Mar 2000) |

| superior recess of lesser peritoneal sac | Pneumoenteric recess, a recess of the embryonic celom between the right lung bud and the gut; it is normally largely obliterated before birth, leaving only the superior recess of the vestibule of the lesser peritoneal sac as a vestige. (05 Mar 2000) |
| dialysis, peritoneal | Technique that uses the patient's own body tissues inside of the belly (abdominal cavity) to act as a filter. The intestines lie in the abdominal cavity, the space between the abdominal wall and the spine. A plastic tube called a dialysis catheter is placed through the abdominal wall into the abdominal cavity. A special fluid is then flushed into the abdominal cavity and washes around the intestines. The intestinal walls act as a filter between this fluid and the blood stream. By using different types of solutions, waste products and excess water can be removed from the body through this process.

| tuberculosis, peritoneal | Tuberculosis of the serous lining of the abdomen. (12 Dec 1998) |
| lesser peritoneal cavity | <anatomy> An isolated portion of the peritoneal cavity lying dorsal to the stomach and extending craniad to the liver and diaphragm and caudad into the greater omentum; it opens into the general peritoneal cavity at the epiploic foramen. Synonym: bursa omentalis, lesser peritoneal cavity, lesser peritoneal sac, omental sac. (05 Mar 2000) |
| lesser peritoneal sac | <anatomy> An isolated portion of the peritoneal cavity lying dorsal to the stomach and extending craniad to the liver and diaphragm and caudad into the greater omentum; it opens into the general peritoneal cavity at the epiploic foramen. Synonym: bursa omentalis, lesser peritoneal cavity, lesser peritoneal sac, omental sac. (05 Mar 2000) |
| activated macrophage | A mature macrophage, in an active metabolic state, that is cytotoxic to tumour/target cells, usually following exposure to certain cytokines. Synonym: armed macrophage. (05 Mar 2000) |
| alveolar macrophage | Macrophage found in lung and that can be obtained by lung lavage, responsible for clearance of inhaled particles and lung surfactant. Metabolism slightly different from peritoneal macrophages (more oxidative metabolism), often have multivesicular bodies that may represent residual undigested lung surfactant. (18 Nov 1997) |
| alveolar macrophage elastase | <enzyme> Metalloproteinase found in human alveolar macrophages Registry number: EC 3.4.24.- Synonym: elastase, alveolar macrophage, metalloproteinase elastase, human macrophage metalloelastase, mmp12 gene product, mmp-12 gene product, mme gene product, macrophage metalloelastase (26 Jun 1999) |
| armed macrophage | A mature macrophage, in an active metabolic state, that is cytotoxic to tumour/target cells, usually following exposure to certain cytokines. Synonym: armed macrophage. (05 Mar 2000) |
| associated macrophage | A mature macrophage in an active metabolic state that is cytotoxic to tumour/target cells, usually following exposure to certain cytokines. (05 Mar 2000) |
| macrophage | Relatively long lived phagocytic cell of mammalian tissues, derived from blood monocyte. Macrophages from different sites have distinctly different properties. Main types are peritoneal and alveolar macrophages, tissue macrophages (histiocytes), Kupffer cells of the liver and osteoclasts. In response to foreign materials may become stimulated or activated. Macrophages play an important role in killing of some bacteria, protozoa and tumour cells, release substances that stimulate other cells of the immune system and are involved in antigen presentation. May further differentiate within chronic inflammatory lesions to epithelioid cells or may fuse to form foreign body giant cells or Langhans giant cells. (18 Nov 1997) |
| macrophage-1 antigen | An adhesion-promoting leukocyte surface membrane heterodimer. The alpha subunit consists of the CD11b antigen and the beta subunit of the CD18 antigen (antigens, CD18). The antigen, which is an integrin, functions both as a receptor for complement 3 and in cell-cell and cell-substrate adhesive interactions. (12 Dec 1998) |
| macrophage-activating factor | An agent that stimulates macrophages to attack and ingest cancer cells. They are secreted by stimulated lymphocytes that prime macrophages to become non-specifically cytotoxic to tumours. They also modulate the expression of macrophage cell surface ia antigens. One maf is interferon-gamma (interferon type II). Other factors antigenically distinct from ifn-gamma have also been identified. (12 Dec 1998) |
| macrophage activation | The process of altering the morphology and functional activity of macrophages so that they become avidly phagocytic. It is initiated by lymphokines, such as the macrophage activation factor (maf) and the macrophage migration-inhibitory factor (mmif), immune complexes, c3b, and various peptides, polysaccharides, and immunologic adjuvants.
