Multiple antibiotic resistance threatens successful treatment of Acinetobacter baumannii infections worldwide. Increasing interest in the well-known activity of sulbactam against the genus Acinetobacter has been aroused. The purpose of this study was to compare the outcomes for patients with Acinetobacter bacteremia treated with cefoperazone/sulbactam(More)
Dendritic cell-based cancer immunotherapy requires tumour antigens to be delivered efficiently into dendritic cells and their migration to be monitored in vivo. Nanoparticles have been explored as carriers for antigen delivery, but applications have been limited by the toxicity of the solvents used to make nanoparticles, and by the need to use transfection(More)
PURPOSE Colistin is used for the treatment of pneumonia associated with multidrug- resistant Acinetobacter baumannii and Pseudomonas aeruginosa. However, the best route of administration and dosage is not known. We report our experience with aerosolized colistin in twelve patients with pneumonia caused by colistin-only-susceptible (COS) A. baumannii. (More)
PURPOSE To identify the clinical features and outcomes of endogenous endophthalmitis in Korea. MATERIALS AND METHODS We reviewed 18 patients with endogenous endophthalmitis at 2 Korean hospitals, treated over a 14 year period between January 1993 and December 2006. RESULTS The comorbidities observed in these cases were diabetes mellitus and liver(More)
OBJECTIVE Haemorrhagic fever with renal syndrome (HFRS), caused by hantavirus infection, develops into acute renal failure (ARF) of variable degrees of severity. We investigated the early predictive markers for oliguric ARF in HFRS patients. METHODS A retrospective cohort study was performed of 61 patients with HFRS between 2000 and 2004. These patients(More)
Aptamers, single-stranded nucleic acids, provide a unique opportunity as amplifiable molecules using polymerase chain reaction (PCR) as well as recognition molecules like antibodies. We report a highly sensitive detection of Escherichia coli by taking advantage of the aptamer amplification as well as the specific binding of aptamers onto E. coli. This(More)
BACKGROUND A well-constructed and properly operating influenza surveillance scheme is essential for public health. This study was conducted to evaluate the distribution of respiratory viruses in patients with influenza-like illness (ILI) through the first teaching hospital-based surveillance scheme for ILI in South Korea. METHODS Respiratory specimens(More)
Amphiphilic α-tocopherol oligochitosan conjugates were constructed by conjugating α-tocopherol succinate to water soluble oligochitosans with various molecular weights. In aqueous medium, the tocopherol oligochitosan conjugates self-assembled to single layered oligomersomes. The sizes of α-tocopherol-oligochitosan-based oligomersomes (TCOsomes) could be(More)
We explored the feasibility of magnetite (Fe(3)O(4))-gold (Au) core-shell nanocrystals as a useful vehicle for biomedical application such as cell separation. Streptavidin-fluorescein isothiocyanate (STA-FITC) was conjugated to the surface of the Fe(3)O(4)-Au core-shell nanocrystals using a carbodimide activation protocol. These nanocrystals were further(More)
Delta neutrophil index (DN) is the immature granulocyte fraction provided by a blood cell analyzer (ADVIA 2120; Siemens Healthcare Diagnostics, Deerfield, Ill), which is determined by subtracting the fraction of mature polymorphonuclear leukocytes from the sum of myeloperoxidase-reactive cells. The purpose of this study was to define the role of DN in(More)
