Tissue distribution studies revealed that the intraperitoneal administration of liposomal CPT was efficient for the delivery of high drug levels to the liver and spleen. Treatment of infected mice with intraperitoneal injections of free and liposomal CPT significantly reduced the parasite loads in the livers by 43 and 55%, respectively, compared with the loads for untreated controls. However, both treatments caused normochromic anemia and neutropenia.\n          <\/jats:p>","DOI":"10.1128\/aac.45.9.2623-2627.2001","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T10:06:42Z","timestamp":1027764402000},"page":"2623-2627","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":31,"title":["Treatment of Visceral Leishmaniasis with Sterically Stabilized Liposomes Containing Camptothecin"],"prefix":"10.1128","volume":"45","author":[{"given":"Marie-Eve","family":"Proulx","sequence":"first","affiliation":[{"name":"<!--label omitted: 1-->Centre de Recherche en Infectiologie, Universite\u0301 Laval, Que\u0301bec, Que\u0301bec, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andre\u0301","family":"De\u0301sormeaux","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Centre de Recherche en Infectiologie, Universite\u0301 Laval, Que\u0301bec, Que\u0301bec, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Franc\u0327ois","family":"Marquis","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Centre de Recherche en Infectiologie, Universite\u0301 Laval, Que\u0301bec, Que\u0301bec, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Olivier","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Centre de Recherche en Infectiologie, Universite\u0301 Laval, Que\u0301bec, Que\u0301bec, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michel G.","family":"Bergeron","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Centre de Recherche en Infectiologie, Universite\u0301 Laval, Que\u0301bec, Que\u0301bec, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1016\/0165-6147(94)90314-X","article-title":"Long-circulating (sterically stabilized) liposomes for targeted drug delivery.","volume":"15","author":"Allen T.
