BACKGROUND Endoscopic sphincterotomy (EST) to remove bile-duct stones is the most frequently used endoscopic technique. Few reports exist regarding application of large-balloon dilation (LBD) after EST for treatment of patients with bile-duct stones. OBJECTIVE To compare the effect of EST plus LBD with that of EST alone. DESIGN A prospective randomized(More)
PURPOSE To assess technical feasibility, efficacy, and complications of percutaneous computed tomography (CT)-guided transthoracic radiofrequency (RF) ablation for treating inoperable non-small cell lung cancer (NSCLC) and lung metastases. MATERIALS AND METHODS Twenty-six patients with 27 NSCLCs and four patients with five lung metastases underwent RF(More)
Up-regulation of fractalkine is involved in vascular and tissue damage in inflammatory conditions. Resveratrol has been shown to have anti-inflammatory, antioxidant, and antitumor activities. Its regulatory effects on expression of fractalkine in vascular endothelial cells and fractalkine receptor CX3CR1 in monocytes have not been studied. We evaluated the(More)
We investigated the ectomycorrhizal (ECM) fungal colonization status of Pinus thunbergii mature trees and regenerating seedlings varying in age in coastal pine forests on the east coast of Korea. We established one 20 x 20-m plot at each of two study sites at P. thunbergii coastal forests in Samcheok. Fifty soil blocks (5 x 5 x 15 cm) were sampled at(More)
OBJECTIVE Our objective was to determine the therapeutic efficacy and safety of radiofrequency ablation in the treatment of hepatocellular carcinoma (HCC) in patients with decompensated cirrhosis. SUBJECTS AND METHODS Nineteen patients with 26 HCC nodules (range, 0.8-5 cm; mean, 1.96 cm) and decompensated liver cirrhosis (mean Child score, 10.7) were(More)
Fractures of the tibial spine usually occur in children aged 8 to 14 years. Usually, radiographs will demonstrate a tibial spine fracture, with the degree of displacement. Tibial spine fractures in younger children have not been reported in the previously published literature. We report a tibial spine fracture that occurred in 5-year-old girl. The(More)
Nephrotoxicity is one of the important dose-limiting factors during cisplatin treatment. There is a growing body of evidence that activation of p53 has a critical role in cisplatin-induced renal apoptotic injury. The nicotinamide adenine dinucleotide-dependent protein deacetylase SIRT1 decreases apoptosis through deacetylating of p53, and resveratrol is(More)
PURPOSE To determine the characteristics of horizontal components of partial-thickness tears of the rotator cuff at magnetic resonance (MR) arthrography and to determine whether use of the abduction and external rotation (ABER) position improved detection of a horizontal component in partial-thickness tears. MATERIALS AND METHODS MR studies in 16 patients(More)
INTRODUCTION During distraction osteogenesis, new and highly vascularized bone is formed, with angiogenesis preceding osteogenesis. We investigated the possibility that COMP-Ang1, an angiogenic factor, may facilitate bone formation. METHODS Rats were divided into three groups. Control rats underwent tibial distraction without treatment. In the two(More)
The purpose of this study was to evaluate the feasibility, safety, and effectiveness of radio-frequency (RF) ablation using an internally cooled-tip electrode on renal VX2 tumors implanted in rabbits. Thirty-three rabbits with implanted renal VX2 tumors were divided into two groups: an RF ablation (RFA) group ( n=27) and a control group ( n=6). In the RFA(More)
