It is generally accepted that the spleen contraction is a consequence of humoral stimulation but recent data suggest a role of neural mechanisms. This study tested the hypothesis that the reduction in spleen size in response to low dose epinephrine infusion is a consequence of neurally mediated unloading of baroreceptors. Continuous ultrasonic measurements of spleen volume in response to intrav...
In schistosomiasis japonicum, the major pathologic lesion is the granulomatous inflammation that occurs around parasite eggs trapped in the liver. The size of these granulomas and their major sequela, a rise in portal pressure, both peak between 8 and 10 weeks after infection and then spontaneously decrease. We have shown that the adoptive transfer of the serum, but not lymphoid cells, of 30-we...
Background: Congenital hepatic fibrosis (CHF) is an autosomal hereditary disorder affecting the porto-biliary system. It is a rare hereditary disorder often presenting in childhood or adolescence with hepatomegaly, splenomegaly, and gastrointestinal bleeding. A timely diagnosis of organomegalies by sonography can prevent esophageal varices. Liver transplantation is now the only...
BACKGROUND Patients with cirrhosis usually have thrombocytopenia in discrete levels. The mechanism of thrombocytopenia is thought as splenic sequestration and destruction of platelets, impaired bone marrow generation and diminished hepatic thrombopoietin synthesis. OBJECTIVES The aim of this study was to evaluate serum thrombopoietin levels and its relationship with thrombocytopenia at patien...
Splenomegaly is one of the common complications malaria most commonly associated with Plasmodium Vivax. Due to inadequate treatment, spleen can harbor parasite, which causes recurrent infection leading splenomegaly and splenic rupture. Spleen more prone rupture in acute phase infection. The exact mechanism still unknown but trauma, pressure abdominal muscles on due sneezing coughing plays impor...
Most common tumors of the spleen are hematologic and lymphoid malignancies. Non-lymphoid and non-hematologic tumors of the spleen are very rare, the most common of which are vascular tumors. This group of tumors in the spleen is composed of heterogeneous tumors such as hemangioma, angioendothelioma (AE), littoral cell angioma, and angiosarcoma. There are several histologic forms of AE such as e...
The infection of Yankassa rams with three important trypanosome species affecting livestock, namely, Trypanosoma congolense, T. vivax and T. bruceiproduced both acute and chronic fatal conditions. Chronic infections were induced in the three infections by the application of subcurative doses of diaminazene aceturate (Berenil). Pathological changes in the infected animals included splenomegaly a...
Of 11 children with juvenile myelomonocytic leukemia (JMML) carrying RAS mutations (8 with NRAS mutations, 3 with KRAS2 mutations), 5 had a profound elevation in either or both the white blood cells and spleen size at diagnosis. Three patients had no or modest hepatosplenomegaly and mild leukocytosis at presentation but subsequently showed a marked increase in spleen size with or without hemato...
