Abstract:
Objective To investigate the therapeutic effect and mechanism of ursolic acid on carrageenan-induced chronic nonbacterial prostatitis (CNP) of SD rats. Methods Forty-two SD rats were randomly divided into five groups:normal control group, model control group, Pushitai group, ursolic acid high-dose group, and low-dose group.Except for normal control group, chronic nonbacterial prostatitis model was established using carrageenan. The rats of Pushitai group were treated with the solution of Pushitai at the dose of 148 mg??kg-1??d-1 for twenty days.The rats of ursolic acid high-dose and low-dose groups were administered with ursolic acid at the doses of 100 and 50 mg??kg-1??d-1 for twenty days, respectively. The rats of normal and model control groups were treated with isometric 5% CMC-Na for twenty days.The prostate index (PI) was calculated from the ratio of isolated rat prostate weight and body weight of rat.The expressions of IL-1β, TNF-α, and IL-10 were detected by ELISA. The histology and morphology of the prostate was observed with the aid of hematoxylin-eosin staining. Results Compared with the model control group, PI and the levels of IL-1β, TNF-α, and IL-10 in serum were significantly decreased in ursolic acid high-dose,and low dose groups ( P<0. 05 ) . Moreover, the pathological changes of prostate were improved significantly. Conclusion Ursolic acid has certain therapy effects on chronic nonbacterial prostatitis, which may be related to its regulating the expressions of IL-1β, TNF-α, and IL-10.
