  • Erythropoietin (EPO), a glycoprotein hormone produced from primarily cells of the peritubular capillary endothelium of the kidney, is responsible for the regulation of red blood cell production. We have been investigating the roles of glycosylation site added in the biosynthesis and function of recombinant protein. In this study, we analyzed by immunohistochemical methods adaptive mechanisms to excessive erythrocytosis in transgenic (tg) mice expressing dimeric human erythropoietin (dHuEPO) gene. Splenomegaly was observed over 11~21 times in the tg mice. The 2,672 candidate spleen-derived genes were identified through the microarray analysis method, and decreased genes were higher than increased genes in the spleen. The specific proteins in the increased and decreased genes were analyzed by immunohistochemical methods. Our results demonstrate that problems of abnormal splenomegaly would solve in tg mice overexpressing dHuEPO gene.

  • The purpose of this study was to assess the usefulness of radiographic examination of the splenomegaly associated with drug-induced splenic congestion and to establish the standard goal of the splenomegaly in dogs. Radiographic images of spleen in normal dogs were collected to determine the maximum diameter prior to, and 15 minutes after, administration of acepromazine, ketamine/diazepam combination, or propofol. Significant splenic enlargement was seen after administration of acepromazine, but statistical signalficant was found in a ventrodorsal view only. Splenic size tended to decrease after administration of ketamine/diazepam combination. Significant splenic enlargement was not found after administration of propofol. These results suggest that measurable splenomegaly can be detected by radiographic examination after some kind of drug administration and the evaluation of splenomegaly is more useful at ventrodorsal view than lateral view.

  • An intact male, 3-year old, Sapsari, weighing 29 kg with a history of respiratory distress, anorexia, abdominal distension, and depression for 1 day was referred. Radiographic findings included a C-shaped soft tissue mass in the mid-abdominal cavity and loss of serosal detail. Ultrasonographs showed splenomegaly with hypoechoic coarse parenchyma, loss of venous flow in the dilated splenic veins, and thrombi. Based on image findings, acute isolated splenic torsion was diagnosed. Splenectomy and prophylactic gastropexy was performed. Another case was a spayed female, 8-year old, Shih-tzu, weighing 3.7 kg with a history of intermittent abdominal pain and a palpable abdominal mass for 1 year. Radiographic findings showed splenomegaly characterized by a soft tissue round mass. Ultrasonographs revealed displaced splenic hilum and absence of venous flow in the dilated splenic vein. Chronic isolated splenic torsion was diagnosed and also splenectomy and gastropexy was performed. Two dogs were recovered normally after surgery without any complications. Acute form of isolated splenic torsion showed acute systemic clinical signs, severe C-shaped splenomegaly on radiographs, and loss of all of splenic venous flow, perivenous hyperechoic triangle sign, and thrombi on ultrasonographs. Chronic form of isolated splenic torsion showed chronic obscure clinical signs, moderate splenomegaly on radiographs, and partial loss of splenic venous flow on ultrasonographs.

  • Objectives : To observe the therapeutic effects of an oriental herbal prescription in a hepatocellular carcinoma patient with splenomegaly and pancytopenia. Methods : Modified Sipjeondaebo-tang was prescribed three times a day to a hepatocellular carcinoma patient with splenomegaly and pancytopenia. Laboratory tests were carried out regularly to observe the therapeutic effects of the oriental herbal prescription for pancytopenia. Results : When treated with modified Sipjeondaebo-tang including Cinnamomi Cortex, the levels of white blood cells, red blood cells, hemoglobin, and hematocrit increased. However, aspartate transaminase, alanine transaminase, alkaline phosphatase, gamma-glutamic transpeptidase, total bilirubin, direct bilirubin levels also increased. Conclusions : Administering modified Sipjeondaebo-tang with Cinnamomi Cortex showed effect in improving pancytopenia but an increase in liver enzyme levels was also observed.

  • Visceral leishmaniasis or kala-azar is an endemic parasitic disease in some parts of the world which is characterized by fever, splenomegaly, and pancytopenia in most of the cases. Herein we report an 11 month-old male infant with diagnosis of kala-azar who presented with pallor, hepatosplenomegaly, failure to gain weight, and no history of fever. Surprisingly, fever started after beginning of meglumine antimoniate treatment in this patient. As far as we are aware of, this is a rare presentation of visceral leishmaniasis. Therefore, clinicians especially in endemic areas are highly recommended to include kala-azar among differential diagnosis of unexplained anemia without fever to prevent misdiagnosis of this potentially fatal, but treatable condition.

  • In an endeavor to help understand some typical scan findings and portal hemodynamics in liver cirrhosis, several commonly occurring scan changes and esophageal varices as demonstrated by esophagram were correlated one another from quantitative and qualitative stand points. Clinical materials consisted of 34 patients with proven diagnosis of liver cirrhosis and esophageal varices. Liver scan was performed with colloidal 198-Au and the changes in the size and internal architecture of the liver, splenic uptake and splenomegaly were graded and scored by repeated double-blind readings. The variceal changes on esophagrams were also graded according to the classification of Shanks and Kerley following modification. Of 34 patients, 91% showed definite reduction in liver volume (shrinkage) constituting the most frequent scan change. The splenic uptake and splenomegaly were noted in 73.5 and 79.4%, respectively. The present study revealed no positive correlation between the graded scan findings including shrinkage of the liver, splenic uptake or splenomegaly and severity of variceal changes of the esophagus. Exceptionally, however, apparently paradoxical correlation was noted between the severity of mottlings and varices. Thus, in the majority (73.5%) of patients mottlings were either absent or mild. This interesting observation is in favor of the view held by Christie et al. who consider the mottlings to be not faithful expression of actual scarring of the cirrhotic liver. This also would indicate that variceal changes are to be the results of intrahepatic arteriovenous shunting of blood with hypervolemic load to the portal system rather than simple hypertension secondary to fibrosis and shrinkage.

  • Malaria, caused by any of four species of protozoan parasites of the genus Plasmodium, is charaterized by high fever, anemia and splenomegaly. Although malaria is a cause of significant morbidity and mortality worldwide, in Korea indigenous malaria has been believed to be eradicated by 1984. However, since the case report of native malaria in 1993, reported cases have been increased annually, reaching more than 300 cases in 1996. We experienced a 2 years-old male with fever, severe anemia and splenomegaly who resided in Inchon city. He had the history of travelling to the area (Yunchon) near western Demilitarized Zone for 1 month this summer. After more than 2 weeks without special attention, he was presented with pallor, anemia and splenomegaly. He was diagnosed to have malaria by Plasmodium vivax with the help of peripheral blood smears which showed various forms of malaria, i.e., ring form, trophozoites, shizonts and gametocytes. He was treated successfully with hydroxychloroquine and primaquine. We report this case with brief review of related literature.

  • Isolated splenic torsion is a rare disease, which is usually produced in deep-chest large breed dogs. A five-year old Pitbull terrier and a four-year old Yorkshire terrier were diagnosed as isolated splenic torsion with chronic form. Leukocytosis, anemia and elevated hepatic enzyme level were found in blood test and a large amount of ascites was observed. Abdominal radiography revealed splenomegaly and ascites and ultrasonography showed diffuse hypoechoic change of spleen in case 1 and hyperechoic change of spleen with focal hypoechoic regions in case 2, thromboembolism of splenic vein and abnormal direction of spleen. To identify the underlying disease of isolated splenic torsion, the histopathologic examination of excised spleen is essential and splenic neoplasia was found in case 2. Chronic isolated splenic torsion shows nonspecific clinical signs and laboratory results. Through diagnostic procedure, particularly ultrasonography, prompt diagnosis may be achieved and improve the prognosis of the patient.
