    Notes: Abstract  In this study the clinical usefulness of ultrasonography in the diagnosis of rotator cuff tears was assessed. One hundred twenty-two patients undergoing preoperative ultrasonography were evaluated surgically. Three different ultrasonographic machines were applied with a 7.5-MHz linear-array transducer. Surgery confirmed a sensitivity of 79% for full-thickness tears and 50% for partial thickness tears. In 73 patients with negative ultrasonographic findings, the specifity was 100% for full-thickness tears and 90% for partial-thickness tears. The diagnostic sensitivity for full-thickness tears of the Hitachi EUB-340 system was significantly lower than those of Hitachi EUB-415 and EUB-515, and thus the former cannot be recommended for detection of rotator cuff tears. The sensitivity with regard to partial-thickness tears was also significantly lower with the Hitachi EUB-340 system as compared to the Hitachi EUB-515. There were no significant differences in false-positive rate among the three machines used. In conclusion, accurate ultrasonographic diagnosis of rotator cuff tear requires a high-resolution machine, as well as considerable experience in interpretation.

    Evaluated of the γ-Ray Radiosterilized Cross-Linked PLLA and PLLA/HA In Vivo (2006)

    Notes: There are still some existing problems that are common to all absorbable materials; 1) It cannot be subjected to radiosterilization, 2) Sufficient strength cannot be maintained until the complete bone union is obtained. To solve these problems, PLLA and PLLA/HA were mixed with cross-bridge supplementary agent, Triallyl Isocyanurate (TAIC). Using these materials in vivo, we created andtested γ-ray radiosterilized absorbable bone fixation materials

    Thyroid hormone-induced chondrocyte terminal differentiation in rat femur organ culture (1998)

    Notes: Abstract  Thyroid hormone plays a role in skeletal maturation. The present study was undertaken to investigate the effect of thyroid hormone on growth and maturation of the epiphyseal cartilage in the rat femur organ culture system. The femora increased in both weight and size over time in culture in the absence of serum. The growth rate was suppressed by thyroxine treatment. Thyroxine induced chondrocyte hypertrophy in the area adjacent to the articular surface in the femoral condyle. In this area, the expression of type X collagen, a marker of chondrocyte terminal differentiation, was detected after 21 days in culture by immunohistochemistry and reverse transcription/polymerase chain reaction. These data suggest that thyroxine suppresses cartilage growth by stimulating chondrocyte terminal differentiation.
