Abstract

Objective: Adriamycin (ADR) is an important anti-cancer drug which can cause renal toxicity. Given the known anti-inflammatory and antioxidant effects of Plantago major (P. major), the aim of this study was to determine the effects of hydroalcoholic extract of P. major on ADR- induced nephropathy in rats. Methods: Fifty male Wistar albino rats were randomly divided into 5 groups including: control, ADR (5 mg/kg), ADR + P. major (600 and 1200 mg/kg) and P. major (1200 mg/kg). The animals were treated with P. major extract for 5 consecutive weeks and ADR was intravenously injected on the 7th day of the study. Urine and serum samples were collected on days 0, 14, 21, 28, and 35 for the measurement of serum cholesterol and albumin levels and urine protein excretion rate. At the end of the study, the left kidneys were removed for apoptosis assessment. Results: Administration of ADR significantly decreased serum albumin level and increased serum cholesterol and urine protein excretion rate as well as, apoptotic cell numbers compared to the control group (P < 0.001) while had no effect on glomerular filtration rate (P > 0.05). Treatment with P. major, in both 600 and 1200 mg/kg doses, increased serum albumin level and decreased serum cholesterol concentration, urine protein excretion rate and as well as the number of apoptotic cell compared to the ADR group (P < 0.001). Conclusion: Our results showed that the P. major extract effectively protects against ADR- induced nephropathy by reducing kidney apoptosis and improving renal functioning in rats.
