RESUMO
BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
