Rifaximin has been reported to be effective for the treatment of hepatic encephalopathy (HE) in Europe. However, it is unknown whether Rifaximin is effective for the treatment of HE in Koreans, therefore we conducted a open-label prospective randomized study to evaluate the efficacy of rifaximin versus lactulose in Korean patients. Fifty-four patients with(More)
Multidrug and toxin extrusion 1 (MATE1, SLC47A1), an organic cation transporter, plays an important role in the renal and biliary elimination of various clinical drugs, including the anti-diabetic drug metformin. The goal of this study was to identify and characterize novel genetic variants of MATE1. Five variants in the promoter region and two(More)
BACKGROUND Atypia or follicular lesions of undetermined significance (AUS/FLUS) is a broad cytological category in the Bethesda system for classifying thyroid cytology. This study investigated the diagnostic accuracy of ultrasound (US) analysis of thyroid nodules with AUS/FLUS. PATIENTS AND METHODS Of 5062 subjects with nodules subjected to fine-needle(More)
CONTEXT There are still some controversies regarding the cutoff value and the influential factors of thyroglobulin (Tg) concentration in washout fluid from fine-needle aspiration (FNA) biopsy (FNA-Tg) on cervical lymph nodes (LNs) in patients with papillary thyroid cancer (PTC). OBJECTIVE Our aims were to validate the cutoff value of FNA-Tg in diagnosing(More)
PURPOSE In contrast to the Western population, the prevalence of Barrett's esophagus (BE) is rare in the Korean population. However, the recent increase in prevalence of gastroesophageal reflux disease (GERD) may affect the prevalence of BE. The aim of this study was to survey the prevalence of BE and evaluate its risk factors. METHODS Patients between 18(More)
The use of an (18)F-labeled radiopharmaceutical for positron emission tomography (PET) imaging of sympathetic neuronal activity has a tremendous clinical impact because it circumvents the substantial drawbacks of the prototypical imaging agent, (123)I-metaiodobenzylguanidine (MIBG). We describe a 14-year-old male patient who had neuroblastoma and underwent(More)
BACKGROUND It has been unclear as to whether the Rome II criteria could be applied to patients in the Asia region with functional gastrointestinal (GI) diseases. The aim of the present study was to determine if symptoms of Asian patients with functional gastrointestinal disorders formed groups which corresponded to the Rome II diagnostic criteria. METHODS(More)
Gastro-oesophageal reflux disease (GORD) occurs more frequently in Europe and North America than in Asia but its prevalence is now increasing in many Asian countries. Many reasons have been given for the lower prevalence of GORD in Asia. Low dietary fat and genetically determined factors, such as body mass index and maximal acid output, may be important.(More)
Induction of antigen-specific T cell tolerance would aid treatment of diverse immunological disorders and help prevent allograft rejection and graft versus host disease. In this study, we establish a method of inducing antigen-specific T cell tolerance in situ in diabetic humanized mice and Rhesus monkeys receiving porcine islet xenografts. Antigen-specific(More)
AIM To investigate the roles of lymphocytes in the development of dextran sulfate sodium-induced colitis. METHODS Using various doses of dextran sulfate sodium (DSS), we induced colitis in wild-type B6 control and Rag-1 knockout (H-2b haplotype) mice, and evaluated the colitis in terms of symptomatic and histologic parameters, such as weight loss,(More)
