The present study described the case of a 24-year-old man who was diagnosed with multiple gastric hyperplastic polyps in 2004. Repeated Helicobacter pylori tests were negative, and colonoscopy revealed no specific findings. The patient started taking a proton-pump inhibitor and iron supplements as a result of anemia caused from the occasional bleeding from(More)
Although the anterolateral and anteromedial thigh flaps have such disadvantages as anatomical variations in the lateral circumflex femoral system and its cutaneous perforators, they have a sufficient number of cutaneous perforators on the anterior aspect of the thigh in many cases, meaning double anterior thigh flaps can be elevated from the ipsilateral(More)
OBJECTIVE In a rat monoiodoacetic acid (MIA)-induced arthritis model, the amount of MIA commonly used was too high, resulting in rapid bone destruction. We examined the effect of MIA concentrations on articular cartilage and infrapatellar fat pad (IFP). We also established an original system for "macroscopic cartilage and bone score" and "IFP inflammation(More)
OBJECTIVE Lubricin expression in the superficial cartilage will be a crucial factor in the success of cartilage regeneration. Mesenchymal stem cells (MSCs) are an attractive cell source and the use of aggregates of MSCs has some advantages in terms of chondrogenic potential and efficiency of cell adhesion. Lubricin expression in transplanted MSCs has not(More)
Eleven patients who had been surgically treated from 1988 to 1999 were retrospectively reviewed in order to evaluate the efficacy of ventilation tube insertion and mastoidectomy with, or without, mastoid obliteration for intractable middle-ear cholesterol granuloma. The mean age registered was 17.2 years at the time of surgical treatment. All cases were(More)
INTRODUCTION Complete spontaneous necrosis of hepatocellular carcinoma (HCC) without any pretreatment or angiography is rare. We present a rare case of spontaneous complete necrosis of HCC, as confirmed after hepatectomy. PRESENTATION OF CASE The patient, a 74-year-old man with a history of alcoholic hepatitis, was referred to our hospital for(More)

The primary site of mesothelioma was not detected in the thoracic cavity. One year later, he was again removed a mediastinal lymph node metastasis, but the primary site was not detected. Eight months later, he was performed(More)
To clarify the correspondence between Shielding Effectiveness (SE) of shielding materials and their physical property, we propose an equivalent circuit for a shielding effectiveness test apparatus using a dual TEM cell, and show its validity. By considering the structure of dual TEM cell that consists of a pair of cells coupled via an aperture in their(More)
