High homocysteine serum level has been regarded as one of the important factors that influence the development of schizophrenia. Genetic variations of methylenetetrahydrofolate reductase, which is a main enzyme reducing homocysteine level, are reported in schizophrenic patients. We measured the serum level of homocysteine/folate and(More)
PURPOSE Retinal neovascularization in diabetes has been thought to follow the release of local angiogenic factors in the retina. We hypothesize that neovascularization of diabetic retinopathy is a systemic vasculogenesis rather than a local angiogenesis. Thus, we evaluate the concentrations of circulating endothelial progenitor cells (EPCs) and stem cell(More)
Recent investigation using the Sysmex XE-2100 hematology analyzer (Sysmex Corporation, Japan) has demonstrated erroneously high eosinophil counts and abnormal white blood cell (WBC) scattergrams in malaria cases. This study was conducted to assess the diagnostic efficiency of the Sysmex XE-2100 analyzer for malaria. One hundred forty-four patients initially(More)
This study was done to evaluate the therapeutic effects of naltrexone on smoking behaviors and to measure the changing of brain substances for elucidating the mode of action by naltrexone. Twenty-five voluntarily participated healthy male smokers were randomly assigned to naltrexone group or placebo group for 2 weeks. In this study, naltrexone group showed(More)
Colistimethate sodium (CMS) is increasingly used to treat multidrug-resistant Gram-negative bacilli infections. However, the incidence of CMS-associated nephrotoxicity has not been evaluated in patients with carbapenem-resistant Acinetobacter baumannii (CRAB) pneumonia. This retrospective study included 120 patients with CRAB pneumonia treated with(More)
BACKGROUND The aims of our study were to determine the correlation of the strain variation and degree of homogeneity of infecting Helicobacter pylori (H. pylori) with their disease outcomes, and the relevance of duodenal H. pylori expression of cagA and/or vacA gene to the development of duodenal ulcer in Korean patients. METHODS One hundred and twenty(More)
BACKGROUND We compared the LightCycler MRSA advanced test (Roche Diagnostics, Germany) with enrichment culture methods to evaluate the relative diagnostic performance of the LightCycler MRSA advanced test for active surveillance in a high-prevalence setting. METHODS A total of 342 nasal swab specimens were obtained from patients in the intensive care unit(More)
Standardization of medical terminology is essential in data transmission between health care institutes and in maximizing the benefits of information technology. The purpose of this study was to standardize medical terms for laboratory observations. During the second year of the study, a standard database of concept names for laboratory terms that covered(More)
BACKGROUND Standardization of medical terminology is essential for data transmission between health-care institutions or clinical laboratories and for maximizing the benefits of information technology. Purpose of our study was to standardize the medical terms used in the clinical laboratory, such as test names, units, terms used in result descriptions, etc.(More)
