Alveolar lavages were performed repetitively on the normal and transplanted
lungs of dogs that had recieved autografts or allografts without
immunosuppression. One half of the lavage returns was fixed as a cytologic
smear; the other half was subjected to semi-thin section or electron
microscopic examination. Of the staining methods was used, the periodic
acid-Schiff (PAS) and Giemsa techniques were best for differentiating and
counting cells. The Ladewig technique was best for evaluating the presence
and location of fibrin. After autotransplantation, the proportion of
so-called alveolar marcophages increased, reached a peak in 4 to 7 days,
and then returned to normal. Phagocytized fibrin increased for the first
postoperative week, but not extracellular fibrin was ever observed. After
allotransplantation, a progressive decrease in the proportion, size, and
vacuolization of so- called alveolar macrophages was noted along with an
increase in extracellular fibrin. Intracellular fibrin could be detected
only up to the third day. These findings define adequate methods for
preparing and staining material obtained from diagnostic alveolar lavages,
and they suggest that the procedure may serve as an index of lung allograft
rejection.
