Osteomyelitis is generally treated by the systemic administration of antibiotics and continuous irrigation after curettage of the lesion, and bone graft is performed secondarily to treat any bone defect. This treatment is associated with major invasion, and also has adverse effects on other organs. If a superior bone filling material were to be developed(More)
The purpose of the present study was to evaluate the profiles of the bone strength of rats treated from infancy with various drugs. Young female Sprague-Dawley rats were classified into five groups according to the composition of their diets. They underwent resection of their femurs for a three-point flexion test and an impaction test at 6, 8, 12, and 16(More)
It is difficult to repair tears of the meniscus at the white zone by suturing. We considered that there might be an optimal tissue welding temperature when thermally welding the meniscal white zone, so we conducted a thermal welding experiment using bovine and human menisci. The samples prepared after thermal welding were investigated by measuring the(More)
A total of 127 patients with involutional osteoporosis were randomly divided into two groups. The elcatonin group consisted of 67 patients who received 20 units of elcatonin per week administered intramuscularly, together with 0.6g calcium lactate (100mg as calcium) given orally three times daily for 24 weeks. The other 60 patients were assigned to a(More)
Using 168 female Sprague-Dawley rats, we determined whether the peak bone mass could be increased, and which drugs would be effective in suppressing the rate of decrease in bone mass by continuous administration from childhood. At the age of 3 months, these 168 rats were divided into five groups depending on the type of diet that they were fed (control,(More)
We have designed and implemented a scripting environment called "Kumoi" for managing collective VMs in a large-scale data center. Kumoi is unlike other scripting environments because it exploits strong typing with type inference and high-level description. Kumoi introduces several advancements, including treating virtual machines as first-class objects and(More)
The plica synovialis mediopatellaris, a so-called shelf, is found in 20%-50% of normal knees. A shelf syndrome with pain or functional injury is uncommon, however, and cases that occur during the adolescent growth phase are rare. We report a rare case of a bilateral shelf syndrome that developed simultaneously in both knees. The patient was a 13-year-old(More)
In the present clinical trial, interference screws, made of poly-L-lactic acid and applied in 46 knees, were compared to titanium screws employed in 45 knees for reconstructing the anterior cruciate ligament using bone-patellar tendon-bone. An identical surgical technique was applied to both groups; and neither group disclosed apparent side effects such as(More)
We developed a calcium phosphate cement containing arbekacin sulfate and polylactic acid (CPC95AP) and examined its effects on bone strength by injecting the CPC95AP into the femoral medullary cavity in model rats with osteoporosis. Favorable cortical bone strength was maintained for more than 6 months when CPC95AP was injected into the femoral cavities.(More)
