Local graft versus host reaction in the xenogeneic system.

The injection of viable rat spleen cells beneath the renal capsule of cyclophosphamide (CY)-treated adult mice produced a localized graft versus host reaction (GvHR), manifested by the kidney enlargement index (KI). The optimal xenogeneic GvHR was obtained after injection of 30-50 million rat spleen cells into mouse recipients treated 24 hr before with CY, 200 mg/kg intraperitoneally (i.p.), and killed 7 days later. Splenomegaly in recipient mice suggested systemic dissemination of the local GvHR.

Reduction of the graft-versus-host reactivity of mouse and rat spleen cells by 5alpha-androstane-3,17-dione.

The local graft-versus-host reaction as evaluated by the popliteal lymph node enlargement was used for studying the immunosuppressive potency of placental steroid 5alpha-androstane-3,17-dione. Spleen cells from virgin female mice and rats injected subcutaneously with this steroid compound produced in appropriate F1 recipients a significantly weaker reaction (P less than 0.001) than spleen cells from untreated or medium-treated control animals. On the other hand, the pretreatment of cell donors either with 5beta-androstane-3,17-dione or testosterone, the compounds which are not present in the mouse and rat placenta, did not influence the normal graft-versus-host reactivity.
