title: [Employment of the antigen-specific rosette test in the diagnosis of rejection following allogeneic orthotopic kidney transplantation in the pig].
abstract: Investigations of the course were performed by means of an antigenspecific rosette test using a poolantigen from tissue samples of approximately 100 pigspleens with the help of the model of allogenic renal transplantation in 26 female pigs. The animals received no immunosuppressive treatment. In our study with this test 75% all of the rejection episodes by clinical acute and chronic rejection were predictably. In acute rejection a maximum rosette forming cell response was examined in general 2-3 days before a pathological rise of serum creatinine or in the course of a bad clinical state. Under chronic rejection this reaction can be seen 5-14 days before the kidney function will go poor. In spite of the high individuality of original curves statistical analyses indicate a good correlation of the number of antigenbinding cells toward pathological deviation of serum creatinine, as long as blocking factors not protect the transplant against the attack of persisting immunocompetent cells or their effectors. These blocking factors can be monitored in a rosette inhibition test with autolog serum.
