STUDY DESIGN A preliminary report of a new operative method termed selective laminoplasty after the preoperative diagnosis of the responsible level using spinal cord evoked potentials (SCEPs) in elderly patients with cervical spondylotic myelopathy. OBJECTIVE To introduce the method and clinical results for selective laminoplasty. SUMMARY OF BACKGROUND(More)
Recently, arginase is suggested to regulate nitric oxide production by competing with nitric oxide synthase for the same substrate, L-arginine, in experimental asthma. We investigated the role of arginase and its relationship to nitric oxide production after spinal cord injury. Rats were subjected to laminectomy and complete transection of their spinal(More)
Previous studies have revealed that cell therapy using bone marrow stromal cells (BMSCs) could promote motor functional recovery in animals with spinal cord injury (SCI). We describe here the development of cell biology technique and the experimental study of regeneration in SCI. The aim of this study was to investigate the potential for neurological(More)
Calcific myonecrosis is a rare condition characterized by a calcified lesion. Because this lesion sometimes presents as a huge mass with unique radiographic characteristics, it can be confused with soft tissue sarcoma. The appropriate treatment is still controversial. We report here three cases diagnosed as calcific myonecrosis of the lower leg and discuss(More)
(Di)bromotyrosine is formed by the specific reaction of eosinophil peroxidase and can be used as an eosinophil activation marker. In the present study, an antibody for (di)bromotyrosine in proteins was prepared to investigate the pathogenesis of eosinophil-related diseases such as allergic responses. A rabbit polyclonal antibody was raised against(More)
This report describes a case of Staphylococcus aureus infection following open wedge high tibial osteotomy, which was successfully treated with by implant removal and replacement with antibiotic-impregnated calcium phosphate cement along with external fixation. The infection occurred 7 months after primary surgery and was treated by implant removal,(More)
OBJECTIVE Back and buttock pain during pregnancy and the postpartum period generally improves spontaneously and rarely causes problems. However, such pain is infrequently induced by pyogenic sacroiliitis. CASE REPORT We herein present a 37-year-old female patient with no previous medical history who developed pyogenic sacroiliitis with severe right(More)
I In nt tr ro od du uc ct ti io on n: : Oxidative and nitrosative stresses are important for mediating secondary damage following spinal cord injury (SCI). A key player in this process is likely to be nitric oxide (NO) because of its various physiological and pathological roles in the CNS. Arginase, a major metabolic enzyme of the liver, is involved in the(More)
The clinical effects of cefoxitin (CFX) were evaluated in the prophylaxis of postoperative infections in the field of orthopaedics. The clinical response was good in 46 out of 50 patients; an efficacy rate of 92%. Four patients (8%) who did not respond to CFX were suffering from infections due to Mycobacterium tuberculosis (1), suspected Pseudomonas(More)
In patients with rheumatoid arthritis who had symptomatic knee joints at the start of anti-tumor necrosis factor (TNF) therapy, the relationship between local symptoms and knee joint destruction at 94 weeks was retrospectively investigated. Among the patients with rheumatoid arthritis and received anti-TNF therapy, the 32 patients (52 joints) having swollen(More)
