RESUMEN
A pilot study evaluated the efficacy of the drug afalaza (mixture of affinity purified antibodies to PSA and endothelial NO-synthase) compared with the Serenoa repens extract in a model of chronic abacterial prostatitis in Wistar rats caused by suturing of prostate tissue by silk thread. Except for the animals of intact group, rats (n = 13 in each group) underwent intraperitoneal injection of distilled water (10 ml/kg), afalaza (at a doses of 5, 7.5 and 10 ml/kg) or an Serenoa repens extract (50 mg/kg) 1 month after surgery for 45 days. After infusion, the mass, volume, and prostate weighting factor were evaluated, and prostate tissue was examined histologically. 2.5 months after surgery, development of chronic abacterial prostatitis was observed in the control group. Compared with intact group, significant increase in weight, weighting factor, and volume of prostate were detected in control group. Against the background of administration of Serenoa repens extract and afalaza, these parameters were not significantly different from control values. The use of Serenoa repens extract prevented the development of atrophic processes and slowed the development of sclerotic processes. Administration of afalaza at all studied doses prevented the development of sclerotic changes, and a dose of 7.5 ml/kg prevented the development of atrophic processes with the effectiveness matching to Serenoa repens extract. Taking into account the high safety of afalaza, this drug is a promising treatment for chronic prostatitis.
