Argan oil reduces oxidative stress, genetic damage and emperipolesis in rats treated with acrylamide

Acrylamide (AA), a well-known toxicant, is present in high-temperature-processed foods in heated foods. Argan oil (AO), a natural vegetable oil, is receiving increasing attention due to its powerful biological properties. However, limited information is available about its effects in lymphoid organs and bone marrow. The aim of this study is to investigate the effects of AO on hematological parameters, 8-hydroxydeoxyguanosine (8-OHdG), thiobarbituric acid reactive substances (TBARs), protein carbonyl (PCO), glutathione (GSH), myeloperoxidase (MPO) levels, the formation of micronucleus (MN) and megakaryocytic emperipolesis (ME) against AA-induced toxicity in rats. The animals were treated with AA (50 mg/kg/day), AO (6 ml/kg/day per day) and AA + AO (50 mg + 6 ml/kg/day) for 30 days. Treatment of rats with AA significantly decreased the hematological parameters, GSH and MPO activity and PCEs ratio while it increased TBARs, PCOs and 8-OHdG levels and formation of MN and ME. No significant differences were observed in the animals received the AO alone. Co-treatment with AA + AO ameliorated almost all of the alterations caused by AA and exhibited protective effect in rats. Based on the obtained results, we suggest that integration of AO in diet or using its supplements may be a good strategy for improving tissue injury in many diseases. (C) 2017 Elsevier Masson SAS.
