background and aims. mast cells play an important role in allergic reactions, host defense, local homeostasis, inflammation and angiogenesis. the aim of this study was to evaluate the relationship between mast cell counts and different types of periodontitis. materials and methods. gingival specimens were taken from 20 moderate-to-advanced chronic and 19 moderate-to-advanced aggressive periodon...

BACKGROUND Recent studies have suggested that mast-cell activation and inflammation are important in obesity and diabetes. Plasma levels of mast cell proteases and the mast cell activator immunoglobulin E (IgE) may serve as novel inflammatory markers that associate with the risk of pre-diabetes and diabetes mellitus. METHODS AND RESULTS A total of 340 subjects 55 to 75 years of age were group...

in vitro culture systems using bone marrow cells from balb/c mice were set up in medium supplemented with spleen-derived medium. bone marrow cells grown in spleen-derived medium gave rise to cultures containing >97% mast cells. the cells were used in polarisation chemotaxis assays with the intention of determining the effect of nerve tissue-derived neurotransmitters on mast cell migration. some...

the occurrence of mast cells is studied in the normal facial nerve and in the facial nerve post mortem exam of patients with chronic suppurative otitis media without associated facial paralysis. a small number of mast cells were found in the normal facial nerve. these cells were usually located in close proximity to the endoneural and epineural blood vessels. the number of mast cells was increa...

fcεri, the high affinity receptor for ige plays a critical role in triggering the allergic reactions. it is responsible for inducing mast cell degranulation and deliberation of allergy mediators when it is aggregated by allergen and ige complexes. fcεri on the mast cells consists of three subunits; α chain directly binds ige, β chain and dimmer of γ chains together mediate intracellular signali...

Background: Male infertility is a widespread problem and increased number of mast cells-induced by some drugs like sulpiride atipycal antipsychotic drug, ara described in the testis of males, exhibiting impaired sper-matogenesis and fertility disorders. In this study number of mast cells and sertoli cells, thickness of seminiferous tubule’s lamina propria and sperm concentration and viability i...

background & purpose: a stroke occurs when blood flow to a region of the brain is interrupted by the blockage or rupturing of a blood vessel or artery. the most prevalent cause of aphasia is stroke. a brain damage that can effect on receptive & expressive language skills is aphasia. intensive language therapy is the most effective means of treating aphasia. the ciat is one of the novel intensiv...

Introduction: Positive effects of topical application of honey on open skin wounds have been observed, Mast cell are playing role in normal wound healing and its disturbances but the role of mast cells in wound healing in existence of honey is uncertain. Objective: The aim of this investigation was to study the effects of two times per day topical application of honey on the number of mas...

Exhibitionism has historically been viewed as more of a nuisance than a serious criminal justice matter. Research has demonstrated that the number of exhibitionists who are detected re-offending is a significant under-representation of the number who actually re-offend. The objective of this study was to extend a previous study conducted on exhibitionists, while attempting to solve the limitati...
