These xenobiotics interact individually or in combination with biological systems and act as carcinogen or produce other toxic effects including reproductive and degenerative diseases.

In vivo study was also undertaken daily oral administration of flubendiamide (200\u2009mg\/kg) or copper (33\u2009mg\/kg) and both these in combination, and also all these concurrently with of \u03b1-tocopherol to Wistar rats for 90\u2009days.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Flubendiamide and copper produced concentration-dependent cytotoxic effects on splenocytes and at median lethal concentrations, flubendiamide (40\u2009\u03bcM) and copper (40\u2009\u03bcM) respectively produced 71 and 81% nonviable cells, higher number of Tunel+ve apoptotic cells, 7.86 and 9.16% micronucleus and 22.90 and 29.59 comets\/100 cells and DNA fragmentation.

All four tested natural antioxidants (resveratrol, catechin, curcumin and \u03b1-tocopherol) reduced flubendiamide and copper-induced cytotoxic effects in rat splenocytes. Rat splenocytes are very sensitive to flubendiamide and copper-induced cytogenotoxicity, therefore, these can be effectively employed for screening of compounds for their cytogenotoxic potential. \u03b1-tocopherol was effective in restoring alterations in oxidative stress biomarkers and preventing histoarchitectural lesions in spleen.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s40360-020-00405-6","type":"journal-article","created":{"date-parts":[[2020,4,23]],"date-time":"2020-04-23T07:02:48Z","timestamp":1587625368000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["In vitro and in vivo effects of flubendiamide and copper on cyto-genotoxicity, oxidative stress and spleen histology of rats and its modulation by resveratrol, catechin, curcumin and \u03b1-tocopherol"],"prefix":"10.1186","volume":"21","author":[{"given":"Rajesh","family":"Mandil","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atul","family":"Prakash","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anu","family":"Rahal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
