Abstract

Colon transplantation has been proposed as a method to improve the function of an intestinal allograft. The present study examined the risk of colon rejection and the effect of FK506 on colon rejection in BN-->LEW rats with orthotopic bowel transplants. The first 4 groups included rats with untreated allografts (group 1), rats with isografts treated with 0.6 mg/kg FK506 (group 2), rats with allografts treated with 0.6 mg/kg FK506 (group 3), and rats with allografts treated with 0.4 mg/kg FK506 (group 4). In each of these groups (10-12 rats), half of the animals received a small bowel graft only (SB), while the other half received a small bowel, ascending colon, and cecum graft (SBC). The animals were followed daily until they died or were killed at 4 weeks. In group 5, an additional 18 untreated rats with SBC allografts were randomly killed on the third, fifth, seventh, and tenth postoperative days to study the sequential histopathologic and immunopathologic changes of colon rejection. There was no difference in survival, body weight, nutritional parameters, or bacterial contamination after SB and SBC transplantation. Intestinal transit was slower after SBC than SB transplantation (P < 0.05). Sequential histopathologic studies ...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
