Even though rifampicin is an effective drug in the management of tuberculosis, it has been documented to have some toxic effects in humans. Therefore, this study intends to investigate the modulatory effect of vitamins C and E on the hepatotoxicity, sperm quality and brain toxicity of Rifampicin. Forty Wistar albino rats were used, 10 animals per group. Group 1 animals received 0.3 mL of distilled water, the Group 2 animals received the therapeutic dose of rifampicin, Group 3 animals received therapeutic doses of rifampicin plus vitamin E, while Group 4 received therapeutic doses of rifampicin and vitamin C. The administration was performed orally during three months; the animals were sacrificed by cervical dislocation at the end of that period. Blood samples were collected and liver function and lipid profile was analyzed using fully automated clinical chemistry device. The liver, brain and reproductive organs underwent histopathological examination. Sperm samples were collected from the epididymis to achieve count and motility and morphological analysis. Results showed rifampicin alone to raise (p &lt; 0.05) liver function enzymes (Aspartate amino transferase [AST], Serum alanine amino transferase [ALT] and Total Bilirubin) when compared with controls. While the vitamin E treated group showed remarkable protection, the vitamin C treated group showed questionable protection against the rifampicin induced liver damage. Sperm count results showed an important (p &lt; 0.05) increase in the sperm quality in vitamin E and C treated groups. However, the vitamin E plus Rifampicin treated group showed increased lipid peroxidation. The histopathological findings revealed structural damages by rifampicin in liver, brain and epididymis while some remarkable architectural integrity was observed in the antioxidant-treated groups. It can be concluded that vitamin E or C improved sperm quality and protected against the brain damage caused by rifampicin. Moreover, vitamin E demonstrated remarkable hepatoprotection against rifampicin induced damage while vitamin C shows a questionable hepatoprotection.<\/jats:p>","DOI":"10.1590\/s0036-46652010000100007","type":"journal-article","created":{"date-parts":[[2010,3,17]],"date-time":"2010-03-17T08:55:24Z","timestamp":1268816124000},"page":"43-46","source":"Crossref","is-referenced-by-count":37,"title":["Modulatory activity of antioxidants against the toxicity of Rifampicin in vivo"],"prefix":"10.1590","volume":"52","author":[{"given":"Olufunsho","family":"Awodele","sequence":"first","affiliation":[{"name":"University of Lagos-Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alade","family":"Akintonwa","sequence":"additional","affiliation":[{"name":"University of Lagos-Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincent O.","family":"Osunkalu","sequence":"additional","affiliation":[{"name":"University of Lagos-Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Herbert A.B.","family":"Coker","sequence":"additional","affiliation":[{"name":"University of Lagos-Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"112","DOI":"10.1016\/j.tox.2007.03.011","article-title":"Chromosomal composition of micronuclei in mouse bone marrow treated with rifampicin and nicotine, analysed by multicolor fluorescence in situ hybridization with pancentromeric DNA probe","volume":"235","author":"Attia SM","year":"2007","journal-title":"Toxicology","ISSN":"https:\/\/id.crossref.org\/issn\/0300-483X","issn-type":"print"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"270","DOI":"10.1055\/s-0028-1095655","article-title":"Influence of Rifampicin on testosterone metabolism in the rat prostate","volume":"7","author":"Castellanos JM","year":"1975","journal-title":"Hormone Metabol Res"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"237","DOI":"10.1016\/S1382-6689(98)00006-4","article-title":"Modulation of rifampicin toxicity by 6 MFA an interferon inducer obtained from fungus Aspergillus ochraceus","volume":"5","author":"Dhuley JN","year":"1998","journal-title":"Environm Toxicol Pharmacol"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"671","DOI":"10.1080\/10715760500104025","article-title":"When is an antioxidant not an antioxidant?
