Title: Protective Effect of Berberine on Cyclophosphamide-Induced Haemorrhagic Cystitis in Rats
Abstract: The urotoxicity of cyclophosphamide and the protective effect of the herb berberine were investigated in this study. Administration of 150 mg/kg cyclophosphamide intraperitoneally caused a serious haemorrhagic cystitis in rats after 12 hr, including bladder oedema, haemorrhage, and dramatic elevation of nitric oxide metabolites (nitrite+nitrate) in urine and in plasma. To explore whether cyclophosphamide-induced cystitis could be prevented by berberine, rats were pretreated with a single dose or two doses of berberine at 50, 100, or 200 mg/kg intraperitoneally then challenged with cyclophosphamide (150 mg/kg, intraperitoneally). The results indicated that pretreatment of rats with berberine could reduce cyclophosphamide-induced cystitis in a dose-dependent manner. Furthermore, we found that two doses of berberine showed greater protection against cyclophosphamide urotoxicity than when given a single dose. In addition, our data shows that a single dose of 200 mg/kg berberine, or two doses of 100, and 200 mg/kg berberine could completely block cyclophosphamide-induced bladder oedema and haemorrhage, as well as nitric oxide metabolites increase in rat urine and plasma. In conclusion, our findings suggest that berberine could be a potential effective drug in the treatment of cyclophosphamide-induced cystitis, and provides us with the bright hope in the prevention and treatment of cyclophosphamide urotoxicity.
