A cytogenetic study was performed on 4,117 Korean patients referred for suspected chromosomal abnormalities. Chromosome aberrations were identified in 17.5% of the referred cases. The most common autosomal abnormality was Down syndrome and Turner syndrome in abnormalities of sex chromosome. The proportions of different karyotypes in Down syndrome (trisomy(More)
The prevalence studies on specific IgE to toluene diisocyanate (TDI)-human serum albumin (HSA) conjugate in TDI-induced asthma have shown variable results. In this study, we attempted to compare specific IgE bindings to TDI-HSA conjugate and its specificity using 3 different conjugates. Sera were collected from 20 TDI-induced asthma and 10 controls.(More)
The matrix metalloproteinases (MMPs) have been associated with tumor cell invasion and metastasis of human cancers by mediating the degradation of extracellular matrix components. Therefore, these enzymes and their inhibitor (TIMP-2) constitute promising targets in the development of anticancer therapies. In order to investigate the correlation between(More)
Histiocytic necrotizing lymphadenitis (HNL) or Kikuchi's disease is a distinctive, self-limited disorder characterized by necrotizing cervical lymphadenopathy in young individuals. HNL is more prevalent among Asians and is a relatively common disorder among Koreans. A preceding fever, lymphopenia, and occasional skin rashes suggest a viral etiology and(More)
A rare case of gastric cancer associated with gastrojejunal and gastrocolic fistula is presented. A 56-year-old man who had been diagnosed with advanced gastric cancer(Borrmann's type III) 5 months previously was admitted due to watery diarrhea and frequent vomiting for 2 weeks. Fluoroscopic examination was visualized two abnormal passage of contrast medium(More)
Interoperability between different metadata schemas and data is an important issue for various semantic Web-related applications. The definitions and MPEG-7 data for multimedia content instances can't be used with other metadata standards in a semantically interoperable way. As part of an attempt to build a retrieval system that uses various metadata(More)
Allergic response to common environmental agents has been regarded as a main pathogenetic mechanism of bronchial asthma. However, allergic sensitization (atopy) can not be detected in a siginificant number of adult asthmatic patients. The etiology of nonatopic asthma has not yet been defined. To evaluate the possible involvement of autoimmune response(More)
The pathogenetic mechanism of nonatopic asthma has not yet been defined. The idea of a possible involvement of autoimmunity in the pathogenesis of nonatopic asthma has been proposed by earlier studies. To evaluate the possible involvement of autoimmune response against bronchial epithelial cell in the pathogenesis of nonatopic asthma, we measured(More)
