In the last few years, notable technical progress has taken place in ultrasound elastography. Qualitative methods have been replaced by quantitative ones, such as: transient elastography, acoustic radiation force impulse and shear wave elastography. Owing to the fact that the spleen is superficially located, it is possible to obtain reliable measuring accuracy of its hardness using sonoelastography. Lately, many researchers have been investigating how spleen elasticity changes in patients

Introduction
The left upper quadrant is most frequently assessed with sonography in patients with enlarged spleen or in the case of trauma(1). The advantages of sonography over other imaging modalities include: portability of the equipment, which allows the sonographer for rapid evaluation of the patient at the bedside, the non-invasive nature of ultrasound, negligible bioeffects, etc.(1) The rapid development and modernization of modalities is another great advantage of ultrasonography(2

Introduction
Littoral cell angioma (LCA) is a rare vascular neoplasm of the spleen, composed of littoral cells, i.e. cells that line the splenic red pulp sinuses(1). Previous case studies have suggested an association of LCA with neoplasms of the colon, kidney, pancreas, lung, and ovary(2). Nevertheless, reports on imaging findings are rare, and the final diagnosis is made by histology and immunohistochemistry. In recent years, contrast-enhanced ultrasound (CEUS) has emerged as a reliable tool

PurposesThe normal limits of spleen size must be known in order for pathological changes to be noticed. The aim of this retrospective study is to determine the normal limits of spleen size in healthy children and to reveal their relation to sex, age, body height and weight.Patients and methodsThree hundred and ten children (150 girls and 160 boys) between 0–16 years of age in Eastern Anatolia Region who had normal spleen ultrasound appearances were included in this study. The greatest

dissected to investigate the presence of nematode larvae. Thirty fish (42.9%) of the total were parasitized by nematode larvae which were morphologically identified as Anisakis spp. Type II (L3) according to light and scanning electron microscopy. The pathogenic potential of oral inoculation of fresh, frozen, and thermally treated larvae into Wistar rats was elucidated by histological examination of their thymus and spleen. Results obtained indicated that neither cooling nor freezing of the parasite

Immune thrombocytopenic purpura (ITP) is an acquired disease in which autoantibodies to platelets cause their sequestration and destruction by mononuclear macrophages, principally in the spleen. If increased production of platelets by megakaryocytes does not compensate for platelet destruction, the number of circulating platelets decreases (thrombocytopenia), resulting in a characteristic bleeding tendency (purpura). While most children with the disease experience a relatively short and benign

In patients with immune thrombocytopenic purpura (ITP), IgG autoantibody-coated platelets are phagocytized by mononuclear macrophages, primarily in the spleen. Intravenous Rh immune globulin (IV RhIG) has been used since 1983 to treat D+, nonsplenectomized patients with ITP. The beneficial therapeutic effect of IV RhIG is attributed to competitive inhibition of phagocytosis of IgG-coated platelets by IgG anti-D-coated D+ red blood cells (reticuloendothelial or Fc receptor blockade).

From each group, three animals were investigated 42 days after injection, and the remaining four animals were studied after one year. All animals were tested for learning abilities and memory. Finally, samples from blood, brain, heart, kidney, liver, colon and spleen were examined. In the experimental group, the size of amyloid plaques were increased significantly after one year

The resulting Mabs were tested serologically, by flow cytometry, and by immunoblotting. The specificity of each antibody was determined after excluding specificities to common antigens in the Rh, Kell, Duffy, Kidd, MNS, Lewis, Lutheran, P1, Colton, Diego, Xga, and Dombrock blood group systems. In each case only the Ok(a–) RBC sample was nonreactive. The Mabs and the

. Pancreas adiposis is best defined in Computed Tomography and Magnetic Resonance Imaging. However, a series of works proved the usefulness in the diagnostics of that pathology of transabdominal and endoscopic ultrasonography. In that method, the degree of adiposis was based on the comparison of echogenicity of the pancreas and the liver, renal parenchyma, spleen and/or retroperitoneal adipose. Recently, the evaluation was expanded by the evaluation of the degree of pancreatic adipose with the pancreas
