PURPOSE To evaluate the feasibility of MR imaging to depict the in vivo recruitment of superparamagnetic iron oxide (SPIO)-labeled macrophages and to aid diagnosis of graft rejection in kidney transplantation. MATERIALS AND METHODS This study was approved by the institution's committee on animal research. Eighteen male Lewis rats received a kidney(More)
Since the blood and thymus of patients with myasthenia gravis may contain inhibitors of neuromuscular transmission that affect acetylcholine receptors of striated muscle, we used denervated rat muscle to test for inhibitors in 43 serums and 18 thymus glands from such patients. Seven per cent of serums inhibited the binding of 125l alpha-bungarotoxin to(More)
The genetic status of cagA, vacA subtype, iceA1, and babA, and the relationship to gastroduodenal diseases were assessed in Helicobacter pylori isolates in Korea. Seventy-six strains of H. pylori were isolated from the antrum and the corpus of 41 adult patients (22 with peptic ulcer and 19 with gastritis). The cagA, iceA1, and babA genes were assessed by(More)
The iliolumbar ligament is one of the three lumbopelvic ligaments. Recent study has shown that the ligament is not present at birth and is formed from metaplasia of the quadratus lumborum muscle at the end of the first decade. To study the biomechanical functions of this ligament, an apparatus was developed using linear variable differential transformers.(More)
The CCR2 antagonist is a receptor antagonist for monocyte chemoattractant protein-1 and is known to be a potential anti-inflammatory therapeutic agent. Recently used optimized labeling techniques for superparamagnetic iron oxide, macrophage homing, and recruitment toward the infection site can be observed on in vivo MRI. This study details the effect of the(More)
Previous study has shown that the iliolumbar ligament is important in restraining flexion, extension, and lateral bending of L5 on S1, and its effect on axial rotation was not apparent at 6 N-m of loading. An apparatus was devised to further evaluate its role in relation to the torsional stability of the lumbosacral junction. Torque-rotation characteristics(More)
PURPOSE To evaluate the potential of high-resolution magic angle spinning (HR-MAS) 1H nuclear magnetic resonance (NMR) spectroscopy for metabolite characterization and the differentiation of acute rejection after heart transplantation in rat models. METHODS We transplanted syngeneic heart grafts from Lewis rats (n = 4) and allogeneic heart grafts from(More)
PURPOSE We assessed the effects of anti-angiogenic therapy (AAT) on radiation therapy (RT), evaluating the tumor growth and perfusion patterns on dynamic contrast enhanced MR (DCE-MR) images. METHODS Thirteen nude mice with heterotopic xenograft cancer of human lung cancer cell line were used. To observe the interval change of the tumor size and(More)
OBJECTIVES This study determined the effect of alginate adhesive on various bond strengths of alginate to stainless steel. METHODS Three test assemblies were designed and machined in stainless steel for tension, shear and cleavage tests. Alginate adhesive (Fix) was applied thinly and dried for 5 min. Alginate (Blueprint) was then loaded and allowed to set(More)
=Abstract=The DNA (deoxyribonucleic acid) content in 111 samples from 14 renal cell carcinomas (8 samples per one tumor specimen) was analyzed by flow cytometry to investigate DNA heterogeneity in renal cell carcinomas and DNA ploidy patterns were also compared with histologic grade and tumor stage. Of the 50 grade I and 22 grade I1 tumor samples, 46 (92%)(More)
