Abstract

PURPOSE
Chronic bacterial prostatitis(CBP) is one of the most common urological diseases in adult males, for which antibiotic therapy is the gold standard treatment. However, long-term therapy has many side effects and results in antibiotic resistance. For these reasons, a new treatment modality, which can replace the traditional antibiotic therapy, is required. Ginsenoside has various confirmed bacterial clearance effects in the respiratory system and on immune modulation. Urovaxom(R) also has confirmed effects on immune modulation, with a preventive effect on recurrent urinary tract infection(UTI). Therefore, the anti-bacterial and synergistic effects of ginsenoside and Urovaxom(R) were evaluated for the treatment of CBP in an animal model.
MATERIALS AND METHODS
The 60 rats demonstrating CBP were randomly divided into 6 groups; the control, ciprofloxacin, ginsenoside, Urovaxom(R), ciprofloxacin with ginsenoside, and ciprofloxacin with Urovaxom(R) groups. All drug treatments were conducted for 2 weeks. After treatment, the results were analysed microbiologically and histopathologically.
RESULTS
The microbiological cultures of the prostate and urine samples and the histological findings of the prostate demonstrated reduced bacterial growth and improved inflammatory responses in all the experimental groups compared with the control group. The ciprofloxacin, and Urovaxom(R) with ciprofloxacin groups showed statistically significant decreases in bacterial growth and improvements in inflammatory responses compared to the control group(p<0.05). The ginsenoside with ciprofloxacin group showed no statistical significance(p>0.05), but the mean difference was very large.
CONCLUSIONS
Ginsenoside and Urovaxom(R) may be effective materials in CBP treatment, and has synergistic effects as a combination treatment. Therefore, the combination therapy of ginsenoside with ciprofloxacin or Urovaxom(R) with ciprofloxacin will be effective treatments of CBP.

  Fig. 1. Prostate section of a rat with chronic bacterial prostatitis obtained 2 weeks after PBS treatment. The acinar structures are severely shrunken and obliterated. Marked chronic inflammatory cell infiltration and interstitial fibrosis are seen (H&E, Bar=200μm). PBS: phosphate buffered saline.

• 

  Fig. 2. Prostate section of a rat with chronic bacterial prostatitis obtained 2 weeks after ciprofloxacin treatment. The acinar structures are partially atrophied, and mild lymphocytic infiltration, with partial interstitial fibrosis, is seen (H&E, Bar=200μm).

• 

  Fig. 3. Prostate section of a rat with chronic bacterial prostatitis obtained 2 weeks after ginsenoside treatment. The acinar structures are moderately atrophied, shrunken and obliterated. Lymphocyte infiltration, with interstitial fibrosis, is clearly seen (H&E, Bar= 200μm).

• 

  Fig. 4. Prostate section of a rat with chronic bacterial prostatitis obtained 2 weeks after UrovaxomⓇ treatment. The acinar structures are moderately atrophied and obliterated. Chronic lymphocytic infiltration, with moderate interstitial fibrosis, is seen (H&E, Bar= 200μm).

• 

  Fig. 5. Prostate section of a rat with chronic bacterial prostatitis obtained 2 weeks after ginsenoside with ciprofloxacin treatment. The acinar structures are slightly atrophied and obliterated. A few chronic lymphocytic infiltrations, with minimal interstitial fibrosis, are seen (H&E, Bar=200μm).

• 

  Fig. 6. Prostate section of a rat with chronic bacterial prostatitis obtained 2 weeks after UrovaxomⓇ with ciprofloxacin treatment. The acinar structures are almost normal in appearance. Minimal interstitial fibrosis, with focal lymphocytic infiltrations, is seen (H&E, Bar=200μm).
