Microbial contamination of femoral head allografts.
OBJECTIVE To study the incidence of microbial contamination at the bone bank of the United Christian Hospital. DESIGN. Retrospective study. SETTING Regional hospital, Hong Kong. PATIENTS A total of 151 patients (33 men and 118 women) who underwent hip arthroplasty surgery and from whom femoral head allografts were retrieved between January 1994 and March 2000; and 81 patients in whom allogr...
متن کاملHistological features of large bone allografts.
We performed biopsies during reoperation for minor complications in two active young patients 9 and 19 months after massive bone allograft implantation for bone tumour. The grafts were dead and resorption-apposition activity, when present, was predominantly in subperiosteal areas. Inflammatory infiltration was very seldom found. Features considered as 'microfractures' or 'microcracks' were note...
متن کاملPeculiar Immunobiology of Bone Marrow Allografts
Mice are capable of rejecting H-2-incompatible bone marrow grafts after a single lethal exposure to X-rays. The onset of rejection begins 18-24 hr after transplantation and is completed by 96 hr. Maturation of this type of allograft reactivity does not occur until the 22nd day of life. In adult mice, the resistance to marrow allografts can be weakened by administration of cyclophosphamide or de...
متن کاملModerate heat treatment of bone allografts. Experimental results of osteointegration.
The use of bone allografts is often essential in orthopedic surgery. Strict donor screening, including HIV testing 3 months postoperatively, is mandatory before a transplant may be used. Yet these measures do not definitely rule out the possibility of HIV transmission, as there is a window period before infection is revealed by blood testing. Accordingly, there is a need for virus inactivation ...
متن کاملPerioperative donor bone marrow infusion in recipients of organ allografts.
D ESPITE its attended complications. immunosuppression for graft acceptance and the impending threat of chronic rejection are two of the many overwhelming factors that have necessitated the implementation of strategies aimed at inducing donor-specific tolerance (OST). With the postulation that persistence of donor cell chimerism after organ transplantation (Tx) may play a notable role in allogr...
