[Detection of interleukin-8 and nitric oxide in chronic prostatitis]

We detected levels of interleukin-8(IL-8) and nitric oxide(NO) in 62 prostatic fluids. The results were that microbiologic exam, IL-8 content, and NO level in control group were all negative; there was not significant difference on the microbiologic exam and NO level between the chronic prostatitis group and non-prostatitis group; there was significant difference between two groups of IL-8 positive ratio. These results suggest that the IL-8 detected in the prostatic fluid of patients with prostatitis may be a diagnostic indicator of prostatic infection.
