Abstract

Abstract: To evaluate the effect of resveratrol in rats with chronic prostatitis, 24 rats were randomly divided into the negative control, vehicle‐treated and resveratrol groups. The rats in the vehicle‐treated group and the resveratrol group were injected subcutaneously with 17‐β‐oestradiol (0.25 mg/kg) daily for 6 weeks while the rats in the control group were injected with equivalent normal saline. From the 45th day, the rats in the resveratrol group were given resveratrol (10 mg/kg) by gavage per day while the rest rats were given normal saline. After 55 days, all the rats were sacrificed and the prostatic tissue was removed. Morphological changes were examined by light microscope after H&E staining. The expressions of IL‐6, IL‐8 and TNF‐α were determined through ELISA and immunohistochemical staining. As a result, significant inflammatory cell infiltration and fibroblastic hyperplasia were observed in prostatic stroma in the vehicle‐treated group compared with the negative control group, as well as the high expression of IL‐6, IL‐8 and TNF‐α. After resveratrol treatment, inflammatory cell infiltration and fibroblastic hyperplasia were shown prominently reduced. Meanwhile, the expression of IL‐6, IL‐8 and TNF‐α was significantly suppressed. For conclusion, resveratrol could attenuate the prostatic inflammation and downregulate the expression of IL‐6, IL‐8 and TNF‐α in rat with oestradiol‐induced chronic prostatitis.
