[Single lung allotransplantation of Japanese monkeys--an immunohistological appraisal of the acute rejection].
Eleven orthotopic single lung allotransplantations of Japanese monkeys (Macaca fuscata) were done without immunosuppression. In the 7 monkeys acute rejection was obvious on chest X-ray and hematoxyline-eosin (HE) staining of the biopsied specimen. On the chest X-ray film, progressive interstitial shadow of the grafts became apparent at the third postoperative day, and they turned out completely radiopaque at the 6th- or 7th postoperative day. The HE staining revealed prominent perivascular edema at the second postoperative day. Perivascular round cell infiltration appeared at the third day and the massive round cell infiltration was observed in the perivascular region, vascular wall and alveolar wall with the thickening of the alveolar wall. Immunostaining with human antilymphocyte monoclonal antibodies was also performed. CD8 positive cells (suppressor/cytotoxic T cell) were observed in the perivascular region at the second postoperative day, and CD8 positive cells and CD4 positive cells increased in number as the rejection progressed. Judging from the positive immunological cross reactivity between Japanese monkey and human, the early diagnosis of the acute rejection of the grafted lung may be possible by detecting the perivascular CD8 cells, even in the human-beings.
