Peritoneal effusion in a dog secondary to visceral mast cell tumor: A case report
(2001-02-14)
BACKGROUND: Mast cell tumor, one of the most common skin tumors in dogs, may also be found in visceral sites (mainly spleen and liver). When a visceral mast cell tumor is present, neoplastic mast cells may be found in any ...
Mast Cells and Ethanol Consumption: Interactions in the Prostate, Epididymis and Testis of UChB Rats
(Wiley-Blackwell, 2011-09-01)
ProblemAlcoholism has reached alarming proportions while fertility rates slowing in populations. The assessment of inflammatory effects with emphasis on the variation of the mast cells comparing ethanol chronic ingestion ...
Mast cells modulate the inflammatory process in endotoxin-induced uveitis
(2011-05-30)
Purpose: To investigate the role of mast cells and annexin-A1 (Anxa1) in endotoxin-induced uveitis (EIU). Methods: EIU was induced by injection of lipopolysaccharide (LPS) into the paws of rats, which were then sacrificed ...
Immunocytochemical localization of heparin in secretory granules of rat peritoneal mast cells using a monoclonal anti-heparin antibody (ST-1)
(Histochemical Soc Inc, 1997-02-01)
We performed immunogold labeling with an ST-1 monoclonal antibody (IgM), specific for intact heparin, to define the subcellular localization of heparin in mast cells. Rat peritoneal mast cells were fixed by a modified ...
Gap junctions between mast cells and fibroblasts in the developing avian eye
(1995-12-01)
Mast cells are present in the eye of chick embryos from the 14th day onward, displaying metachromatic granules, mainly in the iris anterior surface and pectinate ligament. Ultrastructurally these cells show electron-dense ...
Mast cells and MMP-9 in the lamina propria during eruption of rat molars: quantitative and immunohistochemical evaluation
(Wiley-Blackwell, 2010-08-01)
During the active tooth eruption process, structural changes in the lamina propria are necessary to provide extracellular matrix remodelling and for the establishment of the eruptive pathway. A large number of resident ...
Pharmacological modulation of allergic inflammation in the rat airways and association with mast cell heterogeneity
(Elsevier B.V., 2001-08-24)
Administration of ovalbumin by aerosol to sensitised rats produced a rapid (15 min) protein exudation in different airway tissues, as determined by Evans blue staining. This was associated with marked mast cell degranulation ...
Differential effect of plant lectins on mast cells of different origins
(Associação Brasileira de Divulgação Científica (ABRADIC), 2005-06-01)
Histamine release induced by plant lectins was studied with emphasis on the carbohydrate specificity, external calcium requirement, metal binding sites, and mast cell heterogeneity and on the importance of antibodies bound ...
Characteristics of the histamine release from hamster cheek pouch mast cells stimulated by lectins from Brazilian beans and concanavalin A
(1996-10-10)
We have characterized the histamine releasing effects of lectins extracted from Brazilian beans, in comparison to concanavalin A, in hamster cheek pouch cell suspensions containing mast cells. The lectins from Dioclea ...
ULTRASTRUCTURAL SIMILARITY BETWEEN BAT AND HUMAN MAST-CELL SECRETORY GRANULES
(Karger, 1993-01-01)
Mast cells in the tongue of the bat (Artibeus lituratus) show a well-developed Golgi area and abundant mitochondria in the granule-free perinuclear cytoplasm. Rough endoplasmic reticulum profiles, free ribosomes, mitochondria, ...
