The role of monocyte chemoattractant protein-1 (MCP-1) in the recruitment of blood-derived monocytes in a model of zymosan peritoneal inflammation was investigated. After zymosan injection (1 mg) a rapid influx of polymorphonuclear leukocytes (PMN) and monocytes into the peritoneal cavity associated with mouse MCP-1 (JE) gene activation and protein secretion in the exudates occurred. MCP-1 prod...

Neospora caninum was isolated from the brain of an aborted 4-month-old fetus from a dairy cow herd with endemic neosporosis in Porto, Portugal. The fetal brain homogenate was inoculated interperitoneally first into outbred Swiss Webster mice given dexamethasone and then the peritoneal exudates from these mice was co-inoculated with mouse sarcoma cells in the peritoneal cavity of mice given dexa...

Understanding of spatiotemporal profiling of inflammatory mediators and their associations with MΦ accumulation is crucial to elucidate the complex immune properties. Here, we used murine thioglycollate elicited peritonitis to determine concentrations of 23 inflammatory mediators in peritoneal exudates and plasma before (day 0) and after (days 1 and 3) thioglycollate administration to peritonea...

background: accumulation of pleural and peritoneal fluid is seen in some diseases. in order to diagnose the disease and start the treatment, one of the most important actions will be to differentiate between exudates and transudates. the objective of this study was to determine the diagnostic value of measuring the specific gravity of the fluid through refractometer and strip in differentiation...

BACKGROUND AND PURPOSE Chemokines orchestrate neutrophil recruitment to inflammatory foci. In the present study, we evaluated the participation of three chemokines, KC/CXCL1, MIP-2/CXCL2 and LIX/CXCL5, which are ligands for chemokine receptor 2 (CXCR2), in mediating neutrophil recruitment in immune inflammation induced by antigen in immunized mice. EXPERIMENTAL APPROACH Neutrophil recruitment...

the term is used to denote a condition where free tumor cells or cell complexes multiply in the peri toneal fluid, and, accompanied by the gradual ac cumulation of ascites, there attain a nearly pure culture. The 42 tumors surveyed showed three dis tinctly different patterns of behavior: (a) Six tu mors, mainly malignant lymphomas, grew readily in the ascites form when adequate numbers of cells...

Lymphocytes obtained from spleens or peritoneal exudates of immune donor mice were evaluated for their ability to passively confer protection on recipients subsequently challenged with virulent scrub typhus rickettsiae. Peritoneal exudate lymphocytes (PELs) injected intraperitoneally were able to transfer complete protection against rickettsial challenge by 5 days after immunization, whereas sp...

Anthocyanins are flavonoids which demonstrated biological activities in in vivo and in vitro models. Here in the anti-inflammatory properties of an anthocyanin-enriched fraction (AF) extracted from wild mulberry and the cyanidin-3-glucoside (C3G), the most abundant anthocyanin in diet, were studied in two acute inflammation experimental models, in the peritonitis and in the paw oedema assays, b...

Interleukin-10 (IL-10) is a cytokine that regulates various macrophage functions. To elucidate the involvement of endogenous IL-10 in the early stage of murine salmonellosis, we examined the effect of anti-IL-10 monoclonal antibody (mAb) administration on the host defence mechanism against Salmonella choleraesuis infection. The in vivo administration of anti-IL-10 mAb significantly enhanced hos...
