Treatment of mice with 0.5, 2.0 and 5.0 mg\/kg MAPA for 7 days prior to infection significantly stimulated myelopoiesis in a dose-dependent manner. Moreover, treatment with 0.5 and 5.0 mg\/kg MAPA resulted in 30%\/6 and 40% cures of mice lethally infected with Listeria, respectively. MAPA added directly to the culture dishes hardly affected colony formation by bone marrow cells, suggesting an indirect effect ofthis compound on myelopoiesis in vivo. In summary, the data show that MAPA can modulate the CFU-GM generation and antibacterial resistance in listeriosis. As the ability of hematopoietic tissues to produce phagocytes is of particular significance to mediate resistance to Listeria, the promotion ofbone marrow CFU-GM by MAPA may contribute to a rapid restoration of phagocyte numbers in infected sites, thus mitigating the course of infection.<\/jats:p>","DOI":"10.1191\/096032701669333804","type":"journal-article","created":{"date-parts":[[2003,4,3]],"date-time":"2003-04-03T19:38:43Z","timestamp":1049398723000},"page":"38-45","source":"Crossref","is-referenced-by-count":10,"title":["Stimulation
