    Abstract:
    BACKGROUND AND AIMS: High fat diet (HFD) can lead to liver injury, through oxidative stress and inflammation. The use of natural compounds with antioxidant and anti-inflammatory properties can have a protective potential. We aimed to investigate the effects of Cornus mas (CM) and gold nanoparticles phytoreduced with CM (GNPsCM) on hepatic alterations induced by HFD in rats. METHODS: Female Sprague Dawley rats were randomly divided into four groups: control, HFD, HFD +CM and HFD + GNPsCM. The high fat diet was administered for 32 weeks and CM and GNPsCM were administered for 4 weeks after the HFD period. The high fat diet induced oxidative stress in liver, with lipid peroxidation and decreased antioxidant capacity, inflammation and minimal histological alterations. RESULTS: The administration of CM and GNPsCM reduced lipid peroxidation produced by HFD and increased antioxidant potential in liver homogenates, while increasing inflammatory markers. Histological alterations were slightly improved by the intervention of compounds, and hyaluronic acid content of the liver without statistical significance as compared to HFD group. CONCLUSION: These findings support the potential of these treatments in addressing liver oxidative stress, mitigating liver damage induced by a high-fat diet. This investigation sheds light on the oxidative stress dynamics and histological alterations associated with high-fat diet-induced liver injury, contributing to our understanding of potential therapeutic interventions.
