Popis: Background and objectives N-(4-hydroxyphenyl) acetamide (NHPA) is the most commonly used analgesic and antipyretic agent worldwide; however, it remains the leading cause of drug-induced acute liver failure. This study explored the potential impact of curcumin (Curc) and/or α-lipoic acid (Lip acid) on liver damage induced by NHPA overdose. Materials and Methods Male Wistar rats were intoxicated with a single oral dose of NHPA (1000 mg/kg) and treated with Curc (200 mg/kg p. o.) and/or Lip acid (100 mg/kg i. p.). These treatments were given in 2 doses at 2 hours and 10 hours post-NHPA-administration. Animals were sacrificed 24 hours post-NHPA-administration. Results Treatment with Curc and/or Lip acid showed effective reduction of NHPA-induced liver injury, demonstrated by reducing serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin, as well as hepatic nitric oxide and malondialdehyde. Curc and/or Lip acid treatments counteracted these changes. They also ameliorated NHPA-induced centrilobular hepatocellular necrosis, evidenced by histopathological examination. Moreover, Curc and Lip acid reduced the expression of alpha-smooth muscle actin and collagen III, upregulated by NHPA intoxication in response to oxidative stress and inflammation. Discussion and Conclusion Curc and Lip acid can be considered as promising natural therapies against liver injury, induced by NHPA, through their antioxidant and antifibrotic actions.
