Introduction: Leukocytes causing a wide variety of side effects after transfusion are present in all blood products prepared by standard methods. As a consequence, the use of filter technology for leukoreduction has been widely practiced .According to AABB accreditation in 1996, leukoreduced blood components must contain less than 5×106 leukocytes per unit, but sometimes this value is higher ev...

a case of mycobacterium marinum infection of the nasal cavity is described. a 57 years old man was being on infliximab for 2 years for severe psoriasis presented with five months history of epistaxis, nasal blockage and snoring. local examination revealed bilateral nasal mass. the diagnosis of mycobacterial infection was suspected based upon the histopathological finding of granuloma in the bio...

background and objectives: sub-minimum inhibitory concentration (s-mic) can induce changes in morphology, virulence factors and biochemical properties ofbacterial pathogens. the goal of this study is to determine the sub-mic effect of ciprofloxacin and ampicillin on the haemotytic activity of e. coli. material and methods:two clinical isolates of e. coli with high heamolytic activity was select...

We investigated in vivo neutrophil and lymphocyte function in a patient who lacks Sialyl-Lewis-X, a ligand for the selectin family of leukocyte adhesion molecules (leukocyte adhesion deficiency 11, LAD If). As assessed by skin chamber and skin window techniques, in vivo chemotaxis of neutrophils was markedly impaired (less than 6% of normal values). A marginal pool was present as determined by ...

BackgroundAppendicitis is the most common indication for an emergency operation in children's age. Although none of the laboratory values has not high sensitivity and specificity for the diagnosis of appendicitis, leukocyte count and the percentage of segmented neutrophils are most commonly used. The aim of this study was to determine whether there is a statistically significant correlation bet...

Markedly elevated111 In labeled leukocyte activity suggestive of acute osteomyelitis was observed in a region of a composite mandibular allograft that was photon deficient on 99mTc MDP bone scintigraphy. This finding was later confirmed by surgical pathology. The patient was treated with intravenous antibiotics and returned two months later with persistent bone infection. The foHow-up thr...

The purpose of this study was to investigate the characteristics of pulmonary inflammation caused by Mycobacterium avium-intracellulare (MAI) in individuals with neither predisposing lung disease nor immunodeficiency. We reviewed the records of 20 patients with pulmonary MAI infection (including 19 female patients) whose past history and previous chest radiographs revealed no predisposing lung ...
