Replacement of donor lymphoid tissue in small-bowel transplants

Replacement of donor lymphoid tissue in small-bowel transplants.

The presence of recipient lymphocytes in grafts is thought to equate with rejection. Thus, we wished to follow the fate of lymphocytes after transplant of the small bowel. Three complete small-bowel transplants, two with the liver from the same donor also transplanted, were done successfully. Patients were immunosuppressed with FK 506. 5 to 11% of lymphocytes in the recipients' peripheral blood...

Detection of Postoperative Intestinal Ischemia in Small Bowel Transplants

Small bowel transplantation is acknowledged as auto- and allotransplantation. In both instances, there is up to a 4%-10% risk of postoperative ischemia, and as the small bowel is extremely susceptible to ischemia, the timely diagnosis of ischemia is important. The location of the transplant, whether it is buried in the abdominal cavity or in the neck region, increases the challenge, as monitori...

The effect of alphamune and biomin on histomorphological structure of small intestine and caecal tonsil lymphoid tissue in broiler chicken

This study was conducted because of influence of prebiotics (alphamune) and symbiotic (biomin) on histometrical development of small intestine and lymphatic tissue of caecal tonsil have been not reported on broiler chicken. In this study, different parts of small intestine and caecal tonsil, which is a major area of gut associated lymphatic tissue (GALT) in chicken were selected. One hundred an...

Ileal mucosa-associated lymphoid tissue lymphoma presenting with small bowel obstruction: a case report

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT Lymphoma) of the gastrointestinal tract commonly involves the stomach in the setting of concurrent Helicobacter pylori (H. pylori) infection. Primary ileal MALT lymphoma is rare, and has not been associated with a specific infectious disease. We report a case of a 58-year-old man who presented to the emergency departme...
