BACKGROUND Citrulline concentrations have been proposed as a marker for intestinal allograft rejection. We instituted dried blood spot (DBS) specimen monitoring of citrulline to simplify sample collection posttransplant. This study demonstrates the correlation between plasma and dried blood spot specimen citrulline concentrations after intestinal(More)
We introduced the heterotopic vascularized sternum transplant as a more simple and pure alternative to allogeneic hind limb transplantation for the study of bone marrow transplantation. We report the clinical and histopathological manifestations after transplantation of syngeneic and allogeneic sternal grafts with and without immunosuppression with FK-506.(More)
The creation of successful vascular anastomoses is of primary importance in many surgical fields. Numerous attempts to automate this process have been made. These techniques have slowly gained acceptance, but their use is still limited. This report details feasibility testing of a new prototype stapler that automates the rollover sleeve technique for venous(More)
Replacement of donor lymphoid tissue by lymphocytes of recipient origin is an established phenomenon in small bowel transplants. However, replacement of donor epithelial cells of bowel grafts by host cells has not been demonstrated. The objective of our study was to determine whether donor enterocytes are replaced by host-derived enterocytes in the(More)
A technical innovation of a novel ureter implantation technique on rat kidney allograft transplantation is described. The left kidney graft is transplanted heterotopically into the left infrarenal position, using vascular conduits from donor abdominal aorta and inferior vena cava in continuity to renal vessels, to perform arterial and venous end-to-side(More)
BACKGROUND Histopathologic examination (HP) is the primary method of monitoring intestinal graft rejection. Alterations in mucin levels have been demonstrated in bowel diseases. The aim of this study was to detect early markers of intestinal graft rejection based on mucin and cytokine levels. METHODS Allogeneic and syngeneic orthotopic intestinal(More)
Methods to enhance natural microchimerism, which occurs after any successful organ transplant, are currently explored using unmodified donor bone marrow both in experimental and in clinical trials. Because of the potential immunomodulatory effects of donor bone marrow cells, we performed this study to evaluate the effect of single and multiple(More)
The implantation of fragmented rat intestinal epithelium into the omentum of syngeneic animals results in the formation of a cyst containing neointestine. The purpose of our project was to study the evolution of this neointestine-containing cyst over time. Harvested jejunum and ileum of neonatal DA rats (6 to 8 days old) was digested with collagenase type(More)
