“…Administration of NiCl 2 male Wistar rats resulted in an increase in the reduced glutathione content (GSH), glutathione-S-transferase (GST), glutathione reductase (GR), LPO, H 2 O 2 generation, with a concomitant decrease in the activity of glutathione peroxidase (GPx) ( Prasad et al, 2006 ). Several studies reported oxidative damage in brain of rats exposed to nickel with significantly induced increase of LPO, and reduction of GSH level as well as the decrease of superoxide dismutase (SOD) and catalase (CAT) activities ( Ijomone et al, 2020a , Wang et al, 2020 , De Sousa et al, 2019 , Deniz and Altun, 2020 ). In treated male Wistar albino rats, nitric oxide (NO) and LPO levels in whole brain tissue and plasma increased following nickel sulfate (NiSO 4 , 6 H 2 O) treatment ( Ridnour et al, 2004 , Das and Saha, 2010 ).…”
