Abstract
Background: Pomegranate fruit has high contents of various polyphenols and antioxidants due to which it possesses variety of therapeutic properties. In particular, pomegranate fruit peel and flowers have exhibited high antioxidant activity in different studies. Acetaminophen (APAP) overdose is the most common cause of drug induced liver toxicity including both accidental and intentional types. In our study, we investigated the protecting mechanism of pomegranate fruit juice (PJ) against toxicity caused by APAP in Wistar rats.
Methods: Rats were fed with 0.2% (w/v) pomegranate fruit extract as prophylaxis to counter single dose of APAP (2 g/kg, p.o). After that variation in levels of glutathione, glutathione peroxidase (GPx), and glutathione reductase (GR) were marked.
Results: A single dose of APAP elevated serum toxicity markers including lipid peroxidation. A simultaneous sharp depletion of glutathione and its metabolizing enzymes glutathione peroxidase (GPx), glutathione reductase (GR) was observed. Oral doses of PJ at (0.1% & 0.2% w/v) caused a significant (P<0.001) reduction in toxicity marker enzymes. A striking elevation in antioxidant armory was seen as in response to PJ.
Conclusion: The results provide a clear picture of the defensive effect of PJ against APAP induced hepatic toxicity.
