[Allogeneic small intestine transplantation in inbred rats. Transplantation technic and morphological findings].

In a RtH-1-incompatible in-bred rat strain combination (Brown Norway leads to LEWIS), small intestinal transplantations were carried out using the bypass technique. 5, 10 and 12 days after grafting, the transplanted intestines were histologically examined. On the 5th day primarily granulocyte cell infiltration was found. On day 10 and 12 there was an increase of lymphocyte plasma cellular infiltration. The small intestine showed increasing congestion of the lymphatic vessels, an edematous saturation of the stroma as well as loss of the small intestinal-specific epithelial layer.
