Objectives: The aim of this study was to investigate the combined effects of bone allograft and lowintensity pulsed ultrasound (LIPUS) on osteogenesis using a bone allograft model. Methods: Femora and tibiae were harvested from 8 Wistar rats. These long bones were used for bone allografts. Subsequently, two groups were studied. In the bone allograft group, freeze-dried bone was fixed unilateral...

Enchondroma of the hand is a common lesion with a recurrence rate of up to 13.3% after curettage and bone grafting. Pathologic fractures often occur. Although allograft bone chips are widely used in the surgical treatment of enchondroma, the use of structural allograft bone has not been reported before. This case report presents a recurrent enchondroma of the fifth metacarpal with pathologic fr...

purpose: to investigate the outcomes of keratolimbal allograft (klal) for treatment of total limbal stem cell deficiency (lscd). method: patients with total lscd and adequate tear production were included. a total of 27 klal procedures were performed in 21 eyes of 20 patients with lscd. immunosuppression was achived using mycophenolate and cyclosporine. main outcome measure was improvement in v...

background: successful pregnancy in allopregnant women depends upon the control of graft rejection mechanisms. it has been suggested that some immunosuppressive cytokines contribute to successful pregnancy and transplantation. transforming growth factor beta (tgf-   β) exhibits potent immunoregulatory and anti-inflammatory properties which might prolong graft survival. recent studies suggest a ...

We carried out a prospective study to determine whether the addition of a recombinant human bone morphogenetic protein (rhBMP-2) to a machined allograft spacer would improve the rate of intervertebral body fusion in the spine. We studied 77 patients who were to undergo an interbody fusion with allograft and instrumentation. The first 36 patients received allograft with adjuvant rhBMP-2 (allogra...

CONTEXT Several observational studies have investigated the significance of hypertension in renal allograft failure; however, these studies have been complicated by the lack of adjustment for baseline renal function, leaving the role of elevated blood pressure in allograft failure unclear. OBJECTIVE To examine the relationship between blood pressure adjusted for renal function and survival af...

OBJECTIVE Cryopreserved allograft tissue used in the Norwood procedure for infants with hypoplastic left heart syndrome (HLHS) has the potential to cause marked immunologic sensitization which may complicate potential future heart transplantation, if required. The purpose of this study was to assess the anti-HLA antibody response to allograft patches used in the initial repair of HLHS. METHOD...

OBJECTIVES Despite increased use of diabetogenic immunosuppressive drugs and increased incidence of new-onset diabetes after transplant in renal allograft recipients, there are few case studies on the subject of de novo allograft diabetic nephropathy and interstitial fibrosis/tubular atrophy without specific glomerular changes. We sought to study the outcomes of allograft diabetic nephropathy a...

BACKGROUND Recognition of the symbiotic relationship between the meniscus and articular cartilage is critical to the success of meniscal allograft transplantation. Simultaneous combined meniscal allograft transplantation and cartilage restoration procedures have been proposed for patients with a symptomatic postmeniscectomy knee with a focal chondral defect that would have traditionally been co...

Lung transplantation is a therapeutic option for patients with end-stage lung disease. Acute allograft rejection is a major complication of lung transplantation and is characterized by the infiltration of activated mononuclear cells. The specific mechanisms that recruit these leukocytes have not been fully elucidated. The CC chemokine, RANTES, is a potent mononuclear cell chemoattractant. In th...
