[Heterotopic homograft of the rat stomach: microsurgical technic]

More than by a practical viewpoint, the experimental graft of stomach is very useful like model for the study of gastrointestinal physiopathology. Starting from these considerations the AA. have set up a new method for the execution of stomach heterotopic homograft in rat and they have studied the secretory activity without immuno-suppressed therapy. Not inbred rats have been used; their middle survival has been of 9,3 days. The secretion has been regular up to 5th-6th day; in the same time the AA. have made histopathologic studies on the transplanted stomachs of animals that had been sacrificed at programmed intervals of time, which have outlined the progressive growth of a reaction of intense immunological rejection.
