the immunopathology of sarcoidosis remains elusive despite years of research into this multiorgan disease.however, recent studies have provided new insights into the genetics and immune components involved in the clinical manifestation of the disease. granulomatous inflammation is due to the host immune response to a persistent poorly degradable unknown antigen.mycobacterium tuberculosis (mtb) ...

this study investigated the presence of mast cells in inflammatory aural polyps using light microscopy. the number of mast cells was increased in all examined cases and varied from 2.33 to 41.54 per mm2• the cells were located most commonly around small blood vessels. occurrence of mast cells was not different in various types of polyps, but their density was severely increased in active inflam...

this study evaluated the effects of mesobuthus eupeus (me) scorpion venom on inflammatory response following injection. additionally, the present study examined whether immunotherapy at specific time intervals would be effective on inflammatory response after me venom inoculation. animals were divided randomly into four groups: the first group received ld50 of venom and the second and third gro...

activated macrophages have been classified into classical (m1) and alternative (m2) macrophages. we aimed to establish a method to yield enough number of macrophages to analyze their molecular, biological and immunological functions. we used drugs; adjuvant albumin from chicken egg whites—imject alum (ova- alum) and ova complete freund adjuvant (ova-cfa), to induce macrophages to m2 and m1 resp...

gastroesophageal reflux disease (gerd)  is defined with clinical symptoms  of  heart burning and regurgitation. it may be associated with external esophageal symptoms such as chronic cough, asthma, laryngitis, chronic lung disease, sinusitis and pulmonary fibrosis. in the present study, rats with chronic aspiration of gastroduodenal contentswere studied for  cellular phenotypes  and  cytokine c...

background and objective: inflammatory pseudotumor  is a lesion composed of proliferating spindle cells with mixed inflammatory infiltrates. some authors have proposed the name inflammatory myofibroblastic tumor as a proper descriptive term rather than the vague inflammatory pseudotumor. the aim of this study was to verify the myofibroblastic origin of spindle cells in idiopathic orbital inflam...

background: accumulating evidence indicates that inflammatory cells migrate into the pancreas tissue and play an important role in the pathogenesis of acute pancreatitis (ap). the aim of this study was to establish a flow cytometric method to enumerate these infiltrating cells in the pancreas of an experimental ap. materials and methods: twelve hours after inducing of ap, mice pancreatic tissue...

multiple sclerosis (ms) is an autoimmune disease characterized by recurrent episodes of demyelination and axonal lesion mediated by cd4+ t cells with a proinflammatory t helper (th)1 and th17 phenotypes, macrophages, and soluble inflammatory mediators. the overactive  pro-inflammatory  th1  cells  and  clonal  expansion  of  b  cells  initiate  an inflammatory cascade with several cellular and ...
