ABSTRACT

This study sought to assess the protective effects of resveratrol and avocado oil in relation to paracetamol-induced hepatotoxicity in rats. The rats were divided into five groups, namely the control, paracetamol (600 mg/kg), resveratrol (RES; 10 mg/kg) + paracetamol, avocado oil (AVO; 200 mg/kg) + paracetamol, and RES + AVO + paracetamol groups. The hepatoprotective activity was evaluated by measuring biochemical parameters such as the total antioxidant status (TAS) and the total oxidant status (TOS) in each rat’s liver homogenates. Any DNA damage was assessed by means of a comet assay. The results showed that the TOS levels were significantly increased in the paracetamol group when compared with the control group. The TOS levels were found to be significantly lower in the paracetamol groups, in comparison with the RES, AVO, and RES + AVO groups. Moreover, the TAS levels significantly increased in the RES and RES + AVO groups when compared with the paracetamol group. The histopathological examination revealed necrotic areas in the rats’ livers. Pretreatment with both RES and RES + AVO was found to reverse the oxidative stress parameters, DNA damage, and necrosis induced by paracetamol. These results suggest that a combination of REV and AVO may protect against paracetamol-induced hepatotoxicity due to their antioxidant properties.
