Eighty-four BALB\/c mice were divided in seven groups: group A (negative control), and groups B to G (infected). Blood and liver samples were collected on days 4 and 20 post infection (p.i.). Levels of thiobarbituric acid (TBA) reactive substances and advanced oxidation protein products (AOPP) were assessed in liver samples. Both biomarkers were significantly increased in infected groups on day 4 p.i., while they were reduced on day 20 p.i., compared with group A. Glutathione reductase (GR) activity significantly (<jats:italic>P<\/jats:italic>&lt;0\u00b701) increased on day 4 p.i., in group G, compared with group A. INF-<jats:italic>\u03b3<\/jats:italic>was significantly increased (<jats:italic>P<\/jats:italic>&lt;0\u00b7001) in both periods, day 4 (groups B, C, F and G) and 20 p.i. (groups C, F and G). IL-10 significantly reduced (<jats:italic>P<\/jats:italic>&lt;0\u00b7001) on day 4 p.i. in group B; however, in the same period, it was increased (<jats:italic>P<\/jats:italic>&lt;0\u00b7001) in groups C and G, compared with group A. On day 20 p.i., IL-10 increased (<jats:italic>P<\/jats:italic>&lt;0\u00b7001) in groups F and G. Therefore, our results highlighted that these forms of selenium, associated with the chemotherapy, were able to reduce lipid peroxidation and protein oxidation, providing a beneficial immunological balance between the production of pro- and anti-inflammatory cytokines.<\/jats:p>","DOI":"10.1017\/s0031182014001073","type":"journal-article","created":{"date-parts":[[2014,8,11]],"date-time":"2014-08-11T13:23:27Z","timestamp":1407763407000},"page":"1761-1768","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":14,"title":["Diphenyl diselenide and sodium selenite associated with chemotherapy in experimental toxoplasmosis: influence on oxidant\/antioxidant biomarkers and cytokine modulation"],"prefix":"10.1017","volume":"141","author":[{"given":"CLEBER F.","family":"BARBOSA","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ALEXANDRE A.","family":"TONIN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ALEKSANDRO S.","family":"DA SILVA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MARIA I.","family":"DE AZEVEDO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"DANIELI U.","family":"MONTEIRO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"EMILY P.","family":"WACZUK","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"THIAGO","family":"DUARTE","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CARINE","family":"HERMES","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GIOVANA","family":"CAMILLO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"FERNANDA F.","family":"VOGEL","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"LUCIANA","family":"FACCIO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PAULA T.","family":"TONIN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PATRICIA","family":"WOLKMER","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MARTA R.","family":"LEAL","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MARTA M.
