	Hexavalent chromium (CrVI) compounds are potent toxicants commonly used in numerous industries. Thus, potential toxic effects and health hazards are of high relevance. Selenium (Se) and zinc (Zn) are known for their antioxidant and chemoprotective properties. However, little is known about their protective effects against CrVI-induced renal damage during pregnancy. In this context, the present study aimed to investigate the protective efficacy of these two essential elements against potassium dichromate-induced nephrotoxicity in pregnant&amp;nbsp;&lt;i&gt;Wistar Albino&lt;/i&gt;&amp;nbsp;rats. Female rats were divided into control and four treated groups of six each receiving subcutaneously on the 3rd day of pregnancy, K&lt;sub&gt;2&lt;/sub&gt;Cr&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;7&lt;/sub&gt;&amp;nbsp;(10&amp;nbsp;mg/kg, s.c. single dose) alone, or in association with Se (0.3&amp;nbsp;mg/kg, s.c. single dose), ZnCl&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;(20&amp;nbsp;mg/kg, s.c. single dose) or both of them simultaneously. The nephrotoxic effects were monitored by the evaluation of plasma renal parameters, oxidative stress biomarkers, DNA damage, and renal Cr content. The obtained results showed that K&lt;sub&gt;2&lt;/sub&gt;Cr&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;7&lt;/sub&gt;&amp;nbsp;disturbed renal biochemical markers, induced oxidative stress and DNA fragmentation in kidney tissues, and altered renal histoarchitecture. The co-administration of Se and/or ZnCl&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;has exhibited pronounced chelative, antioxidant, and genoprotective effects against K&lt;sub&gt;2&lt;/sub&gt;Cr&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;7&lt;/sub&gt;-induced renal damage and attenuated partially the histopathological alterations. These results suggest that Se and Zn can be used as efficient nephroprotective agents against K&lt;sub&gt;2&lt;/sub&gt;Cr&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;7&lt;/sub&gt;-induced toxicity in pregnant&amp;nbsp;&lt;i&gt;Wistar Albino&lt;/i&gt;&amp;nbsp;rats.

Se and Zn are essential trace elements, known to play a crucial role in thyroid homeostasis. However, there is a lack of data reporting thyrotoxicity during gestation. In this study, we investigated the protective effects of selenium and zinc against potassium dichromate–induced thyrotoxicity in pregnant Wistar rats. Thirty pregnant Wistar rats were divided into control and four treated groups receiving subcutaneously (s.c) on the 3rd day of pregnancy, K2Cr2O7&amp;nbsp;(10 mg/kg, s.c) alone, or in association with Se (0.3 mg/kg, s.c), ZnCl2&amp;nbsp;(20 mg/kg, s.c), or both of them simultaneously. The hormonal profile, oxidative stress biomarkers, DNA damage, and histological modifications were evaluated. Our main findings showed that K2Cr2O7&amp;nbsp;promoted hypothyroidism, oxidative stress, genotoxicity, and histological alterations in the thyroid gland. The co-treatment with Se or ZnCl2&amp;nbsp;has mitigated K2Cr2O7-induced thyrotoxicity in pregnant Wistar rats by exhibiting antioxidant and genoprotective effects. However, the combined co-treatment of both of them was less thyroprotective, and therefore, further investigations on the synergetic interaction of Se and Zn against CrVI toxicity using different doses and exposure routes are required.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Fedala, Anfal</style></author><author><style face="normal" font="default" size="100%">Adjroud, Ounassa</style></author><author><style face="normal" font="default" size="100%">Abid-Essefi, Salwa</style></author><author><style face="normal" font="default" size="100%">Timoumi, Rim</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Protective effects of selenium and zinc against potassium dichromate–induced thyroid disruption, oxidative stress, and DNA damage in pregnant Wistar rats</style></title><secondary-title><style face="normal" font="default" size="100%">Environmental Science and Pollution ResearchEnvironmental Science and Pollution Research</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2021</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2021</style></date></pub-dates></dates><number><style face="normal" font="default" size="100%">18</style></number><volume><style face="normal" font="default" size="100%">28</style></volume><pages><style face="normal" font="default" size="100%">22563-22576</style></pages><isbn><style face="normal" font="default" size="100%">1614-7499</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language></record></records></xml>
