Histopathological examination of liver and lung in guinea pigs experimentally intoxicated by 3HMI, a degradation product of an allelochemic of Brassica spp, showed the harmful effects of this compound on these organs. The 3HMI produces a hepatic steatosis and interstitial pneumonia with septal hyperemia. These results suggest that the 3HMI could develop a synergic toxic action together with skatole (3MI) as inducing agents of different forms of some diseases detected in cattle grazing Brassica pasture.

MRL/MP-Ipr/Ipr (MRL/Ipr) mice possess radioresistant (9.5 Gy) abnormal stem cells and show a recurrence of autoimmune diseases within 5 mo of conventional allogeneic bone marrow transplantation. We recently have found that the MHC preference exists between hemopoietic stem cells and stromal cells; when bones are engrafted, donor-derived stromal cells present in the engrafted bones can migrate into the recipient bone marrows, which are replaced with both donor-derived stromal cells and hematopoietic cells. Based on these findings, we attempted to prevent the recurrence of autoimmune diseases in MRL/Ipr mice by the transplantation of both bone marrow cells and bone (as a source of stromal cells). MRL/Ipr mice were irradiated (8.5 Gy) and then reconstituted with C57BL/6 bone marrow cells plus bone grafts. The mice survived more than 48 wk after this treatment. Immunohistologic studies revealed that the mice were completely free from both lymphadenopathy and autoimmune diseases such as lupus nephritis and rheumatoid arthritis. Sera from these mice showed normal levels of circulating immune complexes and rheumatoid factors. Normal functions of both T cells and B cells were noted. Abnormal T cells such as Thy-1+B220+ cells present in nontreated MRL/Ipr mice could not be seen in the thus-treated mice. In addition, to our surprise, spleen cells from treated mice showed completely normal in vitro primary anti-SRBC responses. These results indicate that stromal cells in allogeneic bone marrow transplantation play a crucial role not only in the prevention of graft failure but also in the successful cooperation among APCs, T cells, and B cells. Although MRL/Ipr mice are radiosensitive and usually die of interstitial pneumonia or fatty liver due to the side effects of radiation, it should be noted that this strategy allows a reduction in the radiation dose (9.5 Gy-->8.5 Gy), and that these mice can survive more than 48 wk without showing any symptoms of autoimmune diseases.

Cynomolgus macaques were exposed to the Angola strain of Lake Victoria Marburg virus (MARV) by aerosol to examine disease course and lethality. Macaques became febrile 4 to 7 days postexposure; the peak febrile response was delayed 1 to 2 days in animals that received a lower dose; viremia coincided with the onset of fever. All 6 macaques succumbed to the infection, with the 3 macaques in the low-dose group becoming moribund on day 9, a day later than the macaques in the high-dose group. Gross pathologic lesions included maculopapular cutaneous rash; pulmonary congestion and edema; pericardial effusion; enlarged, congested, and/or hemorrhagic lymphoid tissues; enlarged friable fatty liver; and pyloric and duodenal congestion and/or hemorrhage. Fibrinous interstitial pneumonia was the most consistent pulmonary change. Lymphocytolysis and lymphoid depletion, as confirmed by TUNEL (terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling), were observed in the mediastinal lymph nodes and spleen. MARV antigen was detected in the lungs, mediastinal lymph nodes, spleen, and liver of all animals examined. In infected macaques, nuclear expression of interleukin-33 was lost in pulmonary arteriolar and mediastinal lymph node high endothelial venule endothelial cells; interleukin-33-positive fibroblastic reticular cells in the mediastinal lymph node were consistently negative for MARV antigen. These macaques exhibited a number of features similar to those of human filovirus infections; as such, this model of aerosolized MARV-Angola might be useful in developing medical countermeasures under the Animal Rule.
