We have found that activated resident peritoneal macrophages from Wistar-Furth and Sprague-Dawley rats produce significantly more superoxide (2.2 +/- 0.4 and 3.6 +/- 0.8 nmol of cytochrome c reduced/10(6) cells/10 min respectively) than those from Lewis rats (1.0 +/- 0.3 nmol of cytochrome c reduced/10(6) cells/10 min). Similar results are found in macrophages elicited with intraperitoneal thioglycolate. Furthermore, nitrate excreted in the urine increased greatly when either Wistar-Furth or Sprague-Dawley rats are injected i.p. with iota carrageenan (0.25 g), a response that did not occur with Lewis rats. This strain difference in the manifestations of the inflammatory response correlates with previous observations that Wistar-Furth and Sprague-Dawley rats, but not Lewis rats, develop suture-line colonic tumors when the ureters and bladder base are implanted into the colon.

UI MeSH Term Description Entries
D008262 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. Activation, Macrophage,Activations, Macrophage,Macrophage Activations
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.
