Objective: To investigate the therapeutic effect of pentosan polysulfide sodium (PPS) on chronic non-bacterial prostatitis (CNP) in rats.
Methods: Based on Robinette's method, we established a CNP model in 80 male SD rats, aged 6 months and weighing 315 - 450 g, by castration followed by subcutaneous injection of estradiol at 0.25 mg / (kg x d) for 30 consecutive days.
