Graft-versus-host-disease was produced in newborn Brown Norway (BN) rats with an intravenous (iv) injection of adult allogeneic Lewis (L) lymph node cells (experimental) and the response was compared to littermates injected with adult syngeneic BN cells (control). By 4 days the reaction in the spleen of experimental animals was such that the spleen index was 1.70 and 2.58 on day 7, and continued to increase until death. A one hour iv pulse of tritiated deoxythymidine (3HdT) administered to experimental and control animals revealed a whole organ peak incorporation of3HdT on day 6 in experimental spleens. A second larger peak occurred on day 10 in the experimental spleen as compared to a single peak at days 6 or 7, respectively, in the experimental mesenteric and combined superficial lymph nodes. However, analysis of the incorporation of3HdT with respect to organ weight revealed a peak incorporation in animals receiving L cells on day 4–6 with a second smaller peak on day 10 in the experimental spleen and again a single peak on days 5 or 6 in the lymph nodes. Total3HdT incorporation within both experimental lymph node compartments became less than controls by day 15 even though experimental nodes had a larger mass.3HdT incorporation per milligram tissue weight decreased in all tissue compartments of experimental animals by day 13–14. The contribution of donor and host cell proliferation to the various peaks observed is discussed. |
