Background :Cell proliferation is one of the most critical factors in metastasis and prognosis of the malignant tumors.Recent investigations show that the eosinophil granolosytes have an important role in developing of malignant tumors. The relation between cell proliferation and eosinophilic infiltration in oral squamous cell carcinoma (OSCS) with prognosis is unclear.The aim of this study w...

Asthma symptoms include wheezing, coughing, dyspnea, and chest tightness, as well variable degrees of airway blockage hyper-responsiveness. Many biomarkers have been widely studied in asthmatic children for asthma diagnosis monitoring. Clinical decisions related to control status traditionally based on subjective symptoms, rescue medication use, lung function changes. Biomarkers reflecting rema...

Eosinophils are potent inflammatory cells with numerous immune functions, including antigen presentation and exacerbation of inflammatory responses through their capacity to release a range of largely preformed cytokines and lipid mediators. Thus, timely regulation of eosinophil activation and apoptosis is crucial to develop beneficial immune response and to avoid tissue damage and induce resol...

Background Blood eosinophil measurements may help to guide physicians on the use of inhaled corticosteroids (ICS) for patients with chronic obstructive pulmonary disease (COPD). Emerging data suggest that COPD patients with higher blood eosinophil counts may be at higher risk of exacerbations and more likely to benefit from combined ICS/long-acting beta2-agonist (LABA) treatment than therapy wi...

Background: The role of tumor-associated tissue eosinophils and mast cells in the biological behavior tumors remains unclear. Objectives: This study was performed to compare eosinophil cell counts cutaneous squamous carcinoma (cSCC) basal (BCC) head neck evaluate their relationship with clinicopathologic factors. Methods: current descriptive-analytical conducted on histopathologic slides 46 BCC...

Stimulation of unfractionated or nonadherent human marrow cells in agar culture by pokeweed-mitogen-stimulated BALB/c mouse spleen cell conditioned medium (SCM) led, in most cultures, to the exclusive formation of eosinophil colonies. The culture system exhibited linearity of eosinophil colony formation with varying numbers of cells cultured, and the absolute numbers and size of SCM-stimulated ...

A purified murine lymphokine, eosinophil differentiation factor (EDF), was found to be a selective stimulus for the clonal proliferation and differentiation of murine eosinophil progenitor cells, establishing it as the murine eosinophil colony-stimulating factor (Eo-CSF). EDF was also active on human eosinophil progenitors and mature blood eosinophils, but had no effect on neutrophil or macroph...

Myeloid progenitor cell cultures (CFU-C) were established in a double-layer agar system with peripheral blood mononuclear cells from 13 patients with the hypereosinophilic syndrome (HES). Normal controls produced 49% +/- 3.5% eosinophil colonies; results in 7 of the 13 HES patients were within the normal range, while in 5, the proportion of eosinophil colonies was greater than 3 standard deviat...
