Morphological alteration of peritoneal mast cells and macrophages in the mouse peritoneal cavity during the early phases of an allergic inflammatory reaction
(Academic Press Ltd, 2001-01-01)
We investigated the presence of mast cell granules in macrophages following an in vivo model of an allergic reaction. Injection of ovalbumin (100 mug) into the peritoneal cavity of sensitised mice produced a rapid (within ...
Annexin 1: differential expression in tumor and mast cells in human larynx cancer
(Wiley-Blackwell, 2007-06-15)
Annexin 1 protein (ANXA1) expression was evaluated in tumor and mast cells in human larynx cancer and control epithelium. The effect of the exogenous ANXA1 (peptide Ac 2-26) was also examined during the cellular growth of ...
Mast cells in the developing avian eye
(Wiley-Blackwell, 1996-12-01)
Mast cells are present in the eye of Gallus domesticus, appearing in the anterior uvea in embryos at stage 39 HH (13th day). In hatching and adult birds, they are present in the sclera, uvea, pectinate Ligament, and ...
Mast cells in the eyes of Calomys callosus (Rodentia : Cricetidae) infected by Toxoplasma gondii
(Springer, 2002-06-01)
The mast cell is a powerful effector cell for the innate immune system, acting through the secretion of several distinct mediators. Few studies have demonstrated the relationship between mast cells and toxoplasmosis. In ...
Relationship between Mast Cells and the Colitis with Relapse Induced by Trinitrobenzesulphonic Acid in Wistar Rats
(Hindawi Publishing Corporation, 2009-01-01)
The present study aimed to clarify the role of mast cells in colitis with relapse induced in Wistar rats by trinitrobenzenosulphonic acid. Colitis induction increased the histamine concentration in the colon, which peaked ...
Visceral mast cell tumor in a captive black jaguar (Panthera onca)
(2003-03-01)
Little is known about neoplasia in the jaguar (Panthera onca), the largest American feline. A captive black jaguar was diagnosed at necropsy with a mastocytic form of visceral mast cell tumor similar to that which occurs ...
Fluctuation of annexin-A1 positive mast cells in chronic granulomatous inflammation
(Birkhauser Verlag Ag, 2008-10-01)
Objective: We have applied here a model of chronic granulomatous inflammation to study the profile of mast cell activation and their expression of annexin-A1 in the nodular lesion.Materials: Granulomatous inflammation was ...
Dermal mast cell counts in F2 Holstein x Gir crossbred cattle artificially infested with the tick Boophilus microplus (Acari : Ixodidae)
(Blackwell Publishing, 2006-01-01)
The role of dermal mast cells (DMC) in the host resistance to ticks has been studied but it is not totally explained yet. Studies have proposed that zebuine cattle breeds, known as highly resistant to ticks, have more DMC ...
Visceral mast cell tumor and mastocythemia in a dog
(2012-11-01)
Mast cell tumor manifests as a localized proliferation of mast cells in the skin, or less frequently as a systemic disorder, which may be accompanied by the presence of neoplastic mast cells in the peripheral blood ...
Quantification of fibrosis and mast cells in the tissue response of endodontic sealer irradiated by low-level laser therapy
(Springer London Ltd, 2011-11-01)
Low-level laser therapy (LLLT) accelerates tissue repair. Mast cells induce the proliferation of fibroblasts and the development of local fibrosis. The objective of this study was to quantify fibrosis rate and mast cells ...
