Giant cell tumor of the tendon sheath is a tumor, which affects mainly hands people aged 30 to 50 years with female prevalence. Magnetic resonance imaging (MRI) essential for diagnosis and treatment planning. The aim this study evaluate efficacy multiecho gradient-echoes (MeGE) sequence in detecting hemosiderin hallmark tumor. MRIs were performed sample 11 patients mean age 45. With proposed pr...

Hemosiderin deposition is not often recognized on routine examination with hematoxylin and eosin staining; however, iron stains may be helpful in the evaluation of hemosiderin deposition in infant autopsies. This report describes the data obtained from autopsy of 86 infants and children whose deaths were investigated at the Forensic Medicine Council Bursa Morgue Department from January 2000 to ...

BACKGROUND AND PURPOSE Subarachnoid hemorrhage (SAH) is very difficult to diagnose several months after its onset. We thus investigated subarachnoid hemosiderin deposition well after SAH by T2*-weighted MRI, a sensitive method for hemosiderin detection. METHODS To investigate how hemosiderin deposition as confirmed by T2*-weighted MRI contributes to the determination of prior SAH and how the ...

We attempted to clarify the mechanism of the storage iron metabolism. A new program of serum ferritin kinetics was applied for studying the increasing and decreasing phases of ferritin and hemosiderin iron in iron addition and removal in patients with a normal level of iron stores or iron overload. The change of ferritin iron in response to iron addition and removal was rapid in the initial sta...

BACKGROUND Infective exacerbations of COPD are common and are accompanied by neutrophilic bronchitis in sputum. Increased respiratory iron content has been associated with respiratory tract infection, though it is unclear if this represents a predisposing factor for infection or the sequelae of inflammation. Iron overload, as assessed in the airways, may be an important biomarker for recurrent ...

Injections of hemoglobin were given to rats in order to produce hemosiderosis, and selected hemosiderin granules in sectioned cells of proximal convoluted tubules were studied by means of electron microscopy. When examined at high resolution, many of the dense particles that were present in hemosiderin granules proved to have the structure that characterizes the iron hydroxide micelles of molec...

Direct microscopic estimation of the amount of hemosiderin in an unstained bone marrow smear is of great value in the clinical evaluation of iron deficiency and iron excess.' Usually, the highly refractile golden or amber crystals of hemosiderin are easily identified and need be differentiated only from particulate artifacts in the unstained marrow preparation. In the course of evaluating sever...

Ferritin and hemosiderin are two forms of storage iron of strikingly similar chemical and physical characteristics (1). Ferritin is present in dispersed form. within the cell, while hemosiderin is present as insoluble particles which are visible microscopically. The separation of these subst.ances has not been heretofore performed on a quantitative scale, although methods for the extraction of ...

Using three different methods of cells fractionation, hemosiderin granules were isolated from tissues (liver and/or spleen) of three patients. The samples were obtained from a case of idiopathic hemochromatosis, a case of thalassemia major with secondary (transfusional?) hemosiderosis, and a case of transfusional hemosiderosis associated with an unclassified anemia. Iron, nitrogen, and protein ...
