OBJECTIVE: To establish an animal model of chronic nonbacterial prostatitis (CNP) using different doses of purified prostate protein with Freund's complete adjuvant (FCA), and to investigate the relationship of the doses with the success of the model construction.
METHODS: Thirty male Wistar rats were divided into a control (A) and 4 experimental groups (B, C, D and E) of equal number. The latter 4 groups were given multi-loci intracutaneous injection of 1.0 ml of a 1:1 mixture of purified prostate protein at 20, 40, 60 and 80 mg/ml with Freund's complete adjuvant (FCA), and meanwhile intraperitoneally injected with 0.5 ml of pertussis-diphtheria-tetanus vaccine at 0 and 30 days. On the 45th day, the rats were sacrificed for observation of the pathomorphological changes in the prostate glands with the naked eyes and microscope.
RESULTS: Different degrees of chronic inflammation were observed with different degrees of lymphocyte infiltration and interstitial hyperplasia in the experimental rats. More obvious changes were found in Groups C and D than in A, and even more significant in Group E (P < 0.05).
CONCLUSION: The rat model of CNP can be successfully established by multi-loci intracutaneous injection of 1.0 ml of a 1: 1 mixture of purified prostate protein at 40 - 60 mg/ml with FCA, and simultaneously intraperitoneal injection of 0.5 ml of pertussis-diphtheria-tetanus vaccine twice within 30 days.
