We retrospectively reviewed 31 hips with massive bone defect because of aseptic loosening of the acetabulum treated with impacted bone allografts with the Kerboull-type acetabular device. Mean age at surgery was 67.9 years, and mean duration of follow-up was 6.3 years. Thickness of the bone graft was evaluated by postoperative radiography. Seven hips showed(More)
Increased oxidative stress is considered one of the main causes of steroid-induced osteonecrosis of the femoral head (ONFH). The aim of this study was to evaluate the effects of a steroid hormone and pentosan polysulfate sodium (pentosan), a heparin analog, in stroke-prone spontaneously hypertensive rats (SHRSP) as a model of ONFH. One hundred twenty-three(More)
BACKGROUND High-dose administration of a steroid hormone has been associated with a major risk of osteonecrosis. In this study we investigated the effects of a steroid hormone on the incidence of osteonecrosis of the femoral head in stroke-prone spontaneously hypertensive rats/Nagasaki (SHRSP/Ngsks). METHODS A total of 71 SHRSP/Ngsks were divided into two(More)
BACKGROUND Pentosan polysulfate sodium (pentosan) is a semi-synthetic drug manufactured from beech-wood hemicellulose by sulfate esterification of the xylopyranose hydroxyl groups. From in vitro and animal model studies, pentosan has been proposed as a disease modifying osteoarthritis drug (DMOAD). The objective of this study was to assess the efficacy,(More)
The average life span of stroke-prone spontaneously hypertensive rats (SHRSP) is about eight months. Male SHRSPs at 40 weeks old were used to study the idiopathic osteonecrosis of the femoral head (ION). The control group showed about 40% old necrosis and 20% early necrosis. The group administered with steroid hormone showed an increasing degeneration of(More)
BACKGROUND AND PURPOSE Although the definite cause of steroid-induced osteonecrosis of the femoral head (ONFH) is unknown, peripheral circulatory failure, lipid metabolism disturbance, and increased oxidative stress are considered to be possible causes. We investigated whether pravastatin as a statin treatment reduces (1) the incidence of ONFH, (2) the(More)
*1 Hiroshima Machinery Works *2 Hiroshima Research & Development Center, Technical Headquarers In the present container yard, container boxes are mainly handled manually with a rubber-tired gantry crane (RTG). Terminal operators have strongly requested automated handling equipment to save on labor, raise productivity with information, management and enable(More)
Container handling at harbor is conducted using container cranes and rail-mounted gantry cranes (RMGCs). To attain high handling efficiency, an automatic crane operation system needs to adopt a load anti-sway control. On the other hand, safe handling operation not colliding a load with stacked containers in the yard is required. To this point, we applied a(More)
Our previous study has shown that plasminogen activator inhibitor 1 (PAI-1) gene expression and secretion from bone marrow adipocytes increased markedly with dexamethasone administration. The purpose of the present study was to measure the secretion of various adipokines from human bone marrow and blood, and investigate how adipokine secretion changes in a(More)
In recent years, high speed and automation have been promoted to provide higher efficiency for container handling in cranes handling containers such as container cranes and transfer cranes. To bring about automation in these cases, it is important to detect the positioning of hoisting loads accurately. In 1996, Mitsubishi Heavy Industries, Ltd.(MHI)(More)
