Özet

Introduction: The protective and/or therapeutic potential of tadalafil (TDL) on cyclophosphamide (CP)-induced hemorrhagic cystitis (HC) and testicular dysfunction in rats was evaluated. Materials and Methods: The animals except from the control group were divided into four groups and treated with saline, or 1, 5 or 10 mg/kg TDL orally (CP, TDL1, TDL5 and TDL10 groups, respectively) before and after CP injection. Body and organ weights, sperm count, cGMP, nitric oxide (NO), IL-6 and IL-10 levels in serum and bladder tissue, and serum testosterone (T), LH and FSH levels were determined. The histological analysis of bladder and testis was performed and the number of apoptotic cells was determined. Results and Conclusion:The CP group had decreased cGMP and NO levels in the bladder, serum T level (p < 0.05) and sperm count (p < 0.001) and higher IL-6 levels in serum and bladder (p < 0.01). Treatment with TDL resulted in increased cGMP (p < 0.001), NO (p < 0.05) and serum T (p < 0.05) levels. Histological analysis of the CP group showed severe HC in bladder and testicular damage. TDL-treated animals showed a dose-dependent improvement in all of these histological impairments. In conclusion, a selective inhibitor of phosphodiesterase-5 enzyme, TDL, showed a protective and/or therapeutic effect on CP-induced HC and testicular dysfunction in rats. (C) 2013 S. Karger AG, Basel
