protective effects of the morus alba l. leaf extracts on cisplatin-induced nephrotoxicity in rat
نویسندگان
چکیده
cisplatin (cp) as an important anti-tumor drug causes nephrotoxicity mainly by oxidative stress and renin-angiotensin system (ras). since flavonoids have high antioxidant activity and probable role in the inhibition of ras, this study was designed to investigate the protective effect of hydroalcoholic extract and flavonoid fraction of morus alba leaves on cisplatin-induced nephrotoxicity in rat. extracts of morus alba leaves were prepared and analyzed phytochemically. male rats (160-200 g) were used in this study (n=7-9). normal group received 0.2 ml normal saline intraperitoneally (i.p.) once daily for ten days. control animals received cp on the third day and saline in the remaining days. other groups received either hydroalcoholic extract (200, 400 and 600 mg/kg, i.p.) or flavonoid fraction (50, 100 and 200 mg/kg, i.p.) for two days before cp administration and thereafter until tenth day. serum concentrations of blood urea nitrogen (bun), creatinine (cr) and nitric oxide were measured using standard methods. also left kidneys were prepared for pathological study. the serum levels of bun and cr increased in animals received cp. hydroalcoholic extract was ineffective in reversing these alterations but flavonoid fraction (50 and 100 mg/kg) significantly inhibited cp-induced increases of bun and cr. none of the treatments could affect serum concentration of nitric oxide. flavonoid fraction could also prevent cp-induced pathological damage of the kidney. it seems that concurrent use of flavonoid fraction of morus alba with cp can protect kidneys from cp-induced nephrotoxicity.

Protective effects of ethyl pyruvate in cisplatin-induced nephrotoxicity
This study was performed to investigate the effect of ethyl pyruvate on changes in renal functions and oxidative stress related renal injury caused by cisplatin (cis-dichlorodiammine platinum-II; CDDP). Male Wistar albino rats were divided into four groups (n = 8): (1) control group (1 ml Ringer's lactate solution i.p.); (2) ethyl pyruvate (EP) group (50 mg/kg Ringer's EP solution (REPS) i.p.);...

Introduction: Bromobenzene is an environmental toxin whose metabolites cause renal toxicity. The mechanism involved in toxicity includes oxidative stress. The aim of this study was to investigate the protective effects of berberine against bromobenzene-induced renal toxicity in male NMRI mice. Materials and Methods: In this experimental study, subjects were divided into five groups. Group I...
