The intranephron distribution of two major cysteine S-conjugate β-lyases was determined in order to clarify the role of these enzymes in promoting the nephrotoxicity associated with certain halogenated xenobiotics. Various nephron segments [i.e., glomerulus, early, middle, and terminal portions of the proximal tubule (S1, S2, and S3 respectively), the thick(More)
Serial MRI findings of changes in corpus callosum lesions in two cases of Marchiafava-Bignami disease are presented. In both, MRI displayed diffuse swelling of the corpus callosum in the acute stage, thought to represent oedema and demyelination. In the chronic stage, in addition to atrophy of the corpus callosum with presumed focal necrosis, previously(More)
Mesenchymal stem cells (MSCs) are often known to have a therapeutic potential in the cell-mediated repair for fatal or incurable diseases. In this study, canine umbilical cord MSCs (cUC-MSCs) were isolated from umbilical cord matrix (n = 3) and subjected to proliferative culture for 5 consecutive passages. The cells at each passage were characterized for(More)
Bacterial meningitis remains a serious cause of morbidity and mortality in childhood. Epidemiologic investigations have shown variability in disease risks among different populations and races. In Korea, however, basic epidemiologic information on bacterial meningitis in children is limited. The main purpose of this study was to analyze bacteriologically(More)
Glomus tumor occurs only rarely in the stomach. This benign intramural mass is located most frequently in the distal half of the stomach. We experienced two cases of glomus tumor of the stomach which were examined with helical CT and were confirmed pathologically. Both tumors were well-marginated solitary lesions, located in the gastric antrum. On the(More)
Inflammatory myofibroblastic tumors are lesions that most often affect young adults and children. These tumors have been found in numerous extrapulmonary sites but rarely in the stomach. It is unknown whether this process is reactive or neoplastic. They are infiltrative lesions and often extend through the gastric wall, sometimes reaching adjacent organs(More)
US, portal venous phase CT, and MRI-CSE (MRI with conventional spin-echo sequence) findings in three cases of hepatic involvement in hypereosinophilic syndrome are presented. These showed varied imaging findings, but portal venous phase CT showed multiple, poorly marginated, and hypodense hepatic lesions in all three cases. The result suggested that portal(More)
Serotypings have been used as markers for epidemiological surveys of Streptococcus pyogenes infections. Seventy-seven strains of S. pyogenes isolated from the throats of elementary school children in Kangwon Province in Korea in March and April 1992 were serotyped with M and/or opacity factor (OF) antisera. Sixty-eight strains of S. pyogenes from healthy(More)
Nephritis associated with a chronically infected ventriculoatrial shunt is known as shunt nephritis. A 6-year-old girl with prior history of a ventriculoatrial shunt presented complaining of fever and gross hematuria. Serum complement levels were decreased and a coagulase-negative S. epidermidis was cultured from her blood. The renal biopsy specimen showed(More)
Background: To establish the value of saline-filled appendiceal ultrasonography in the the diagnosis of clinically equivocal acute appendicitis. Methods: Saline-filled ultrasonography was performed in 43 patients with an equivocal clinical diagnosis of acute appendicitis. Results: Sonography diagnosed 31 of 32 patients without acute appendicitis (97%). A(More)
