Berberis integerrima hydro-alcoholic root extract and its constituent berberine protect against cisplatin-induced nephro- and hepato-toxicity

This study determined the potential hepato- and renal protective role of berberine and hydroalcohol extract of Berberis integerrima (barberry) against cisplatin-induced acute liver and kidney injury.Animals were dedicated into six groups (n = 7 per group): control, control+Ber (berberine, 0.4 mg/kg/day during 10 days, i.p.), control+B.E (barberry extract, 160 mg/kg/day during 10 days, i.p.), Cis (cisplatin, 8 mg/kg on 7th day, i.p.), Cis+Ber (berberine, 100 mg/kg/day during 10 days; cisplatin, 8 mg/kg on 7th day), Cis+B.E (barberry extract, 160 mg/kg/day during 10 days; cisplatin, 8 mg/kg on 7th day). After placing the rats in metabolic cages for 24 h, blood, urine, liver and kidney tissue samples were collected.Compared to control, control+Ber and control+B.E groups, cisplatin administration led to kidney and liver dysfunction. These happened with diminished activities of antioxidant enzymes, increased levels of malondialdehyde, Toll-like receptor 4 gene expression and histological damages in hepatic and renal tissues. Berberine and barberry extract administration decreased all the changes.An intensification in enzymatic oxidant status, decrease in lipid peroxidation with decrease in TLR4 gene expression level indicate that barberry extract may be a potential candidate in combating cisplatin-induced oxidative stress and inflammation in liver and kidney tissues through its constituent berberine.
