13. Adenosine: an endogenous mediator in the pathogenesis of psoriasis
Abstract: It is known that inflammatory and immune responses protect us from the invasion of micro-organisms and eliminate "wastes" from the injured sites, but they may also be responsible for significant tissue damage. Adenosine, as a purine nucleoside, which is produced in inflamed or injured sites, fulfills its role in limiting tissue damage. Although, it

14. Mast cell concentration and skin wound contraction in rats treated with Brazilian pepper essential oil (Schinus terebinthifolius Raddi)
PURPOSE:To evaluate wound contraction and the concentration of mast cells in skin wounds treated with 5% BPT essential oil-based ointment in rats.METHODS:Twenty rats, male, of adult age, were submitted to skin surgery on the right (RA) and left antimeres (LA) of the thoracic region. They were divided into two groups: control (RA - wounds receiving daily topi

15. Systemic mastocytosis - a diagnostic challenge
Mastocytosis refers to a group of disorders characterized by the infiltration of clonally derived mast cells to the skin or extracutaneous tissues resulting in a heterogeneous clinical picture. It is a rare hematologic disorder in all its forms. The exact incidence is unknown; it affects patients of any age and males and females equally. Its molecular pathog

16. Adult mastocytosis: a review of the Santo António Hospital 's experience and an evaluation of World Health Organization criteria for the diagnosis of systemic disease
BACKGROUND: Mastocytosis is a clonal disorder characterized by the accumulation of abnormal mast cells in the skin and/or in extracutaneous organs. OBJECTIVES: To present all cases of mastocytosis seen in the Porto Hospital Center and evaluate the performance of World Health Organization diagnostic criteria for systemic disease. METHODS: The cases o

17. The putative role of ovary removal and progesterone when considering the effect of formaldehyde exposure on lung inflammation induced by ovalbumin
OBJECTIVE: Formaldehyde exposure during the menstrual cycle is known to affect the course of allergic lung inflammation. Because our previous data demonstrated that formaldehyde combined with an ovariectomy reduced allergic lung inflammation, we investigated the putative role of ovary removal and progesterone treatment when considering the effect of formald

18. Amitriptyline, clomipramine, and maprotiline attenuate the inflammatory response by inhibiting neutrophil migration and mast cell degranulation
Objective: Despite the recognized anti-inflammatory potential of heterocyclic antidepressants, the mechanisms concerning their modulating effects are not completely known. Thus, we evaluated the anti-inflammatory effect of amitriptyline, clomipramine, and maprotiline and the possible modulating properties of these drugs on neutrophil migration and mast cell

19. Stimulated mast cells promote maturation of myocardial microvascular endothelial cell neovessels by modulating the angiopoietin-Tie-2 signaling pathway
Angiopoietin (Ang)-1 and Ang-2 interact in angiogenesis to activate the Tie-2 receptor, which may be involved in new vessel maturation and regression. Mast cells (MCs) are also involved in formation of new blood vessels and angiogenesis. The present study was designed to test whether MCs can mediate angiogenesis in myocardial microvascular endothelial cells

20. Evaluation of anti-allergic and anti-anaphylactic activity of ethanolic extract of Zizyphus jujuba fruits in rodents
The present study reports the anti-allergic activity of ethanolic extract of Zizyphus jujubaMill., Rhamnaceae, and its possible mode of action. The effect of extract of Z. jujuba at different doses (250, 500 and 1000 mg/kg, orally) was simulated on studied animal models of asthma and allergy: a) milk induced eosinophilia and leukocytosis; b) compound 48/80 i

21. Behavior of the P1.HTR mastocytoma cell line implanted in the chorioallantoic membrane of chick embryos
The P1.HTR cell line includes highly transfectable cells derived from P815 mastocytoma cells originating from mouse breast tissue. Despite its widespread use in immunogenic studies, no data are available about the behavior of P1.HTR cells in the chick embryo chorioallantoic membrane model. The objective of the present investigation was to study the effects o

22. Estudo comparativo dos efeitos da dexametasona e do diclofenaco sódico sobre o processo reparativo de feridas induzidas no ventre lingual de ratos / Comparative study of the effects of dexamethasone and diclofenac sodium on the repair process of induced wounds in the ventral tongue of rats
Inflammation is a protective response to rid the body of the initial cause of cell damage and its consequences, but when excessive and unmodulated, may cause progressive destruction of tissue. The aim of this study is to clarify the influence of two anti-inflammatory, diclofenac sodium and dexamethasone on the inflammatory phase of tissue repair process, as

23. O impacto da exposição pré-gestacional à poluição atmosférica sobre o processo de implantação embrionária em camundongos / The impact of pre-gestational exposure to air pollution on embryonic implantation process in mice
Nós humanos estamos inevitavelmente expostos a uma mistura de poluentes, e evidências nos mostram que estes poluentes aumentam a incidência de desordens reprodutivas. Já se sabe que camundongos cronicamente expostos a níveis de poluentes ambientais em São Paulo apresentam: mudanças no ciclo estral, alteração no número de folículos ovarianos, aumen

24. Renal macrophage infiltration is associated with a poor outcome in IgA nephropathy
OBJECTIVES: The objectives of our study were as follows: 1) to analyze the prognostic value of macrophage infiltration in primary IgA nephropathy (IgAN) and 2) to study the relationship between macrophages and other factors associated with the development of renal fibrosis, including mast cells, TGF-β1, α-SMA and NF-kB. METHODS: We analyzed 62 patients who
