1 만성세균성전립선염모델쥐에서 Ginsenoside 혹은 Urovaxom R 과 Ciprofloxacin 의상승효과 Synergistic Effect between Ginsenoside or Urovaxom R with Ciprofloxacin on Chronic Bacterial Prostatitis Rat Model Yong-Sun Choi, Yong-Hyun Cho, Chang-Hee Han From the Department of Urology, College of Medicine, The Catholic University of Korea, Seoul, Korea 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 ananimal 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.

7 최용선외 : 만성세균성전립선염모델쥐에서 Ginsenoside 혹은 Urovaxom R 과 Ciprofloxacin 의상승효과 855 전체남성인구중에서 50% 정도가적어도한번은이에이환되는것으로알려져있으나, 임상양상이비특이적이며, 아직까지명확히알려진병인론이없어진단과치료에있어서어려움이많은실정이다 이러한만성세균성전립선염은비록생명을위협하는중대한질환은아니지만, 발병시수개월동안지속될수있으며, 재발이잦아환자의삶의질에지대한영향을미칠수있다. 그럼에도불구하고아직정확한통계는없는실정이다. 20 만성세균성전립선염의임상적특징은하부요로에서기인한상행감염이라는점이다. 이를기초로저자들은본실험에서만성세균성전립선염실험모델을만들어시행하였으며, 상기실험모델은인간의만성세균성전립선염과발생및경과의유사성이많으므로이를통해향후만성세균성전립선염의자연경과에대해설명이가능할것으로기대된다. 14 저자들은실험모델에서세균을인위적으로요도를통해전립선에주입하여급성혹은아급성전립선염을유발시켰으며, 급성, 아급성시기가지나면서숙주의방어기제에의한세포면역기전에의해세균이사멸되지않으면만성세균성전립선염을유발시킨것으로정의하였다. 만성세균성전립선염을유발하는원인은세균감염이며이중가장흔한것은 E. coli로알려져있다. 만성세균성전립선염의가장적절한치료는보존적치료로서항생제를사용하는것이다. 그러나만성세균성전립선염에서모든항생제치료가효과가있는것은아닌것으로알려져있다. 이는일반적인만성세균성전립선염의치료에사용되는약제는분자무게가가볍고및지용성으로혈장단백질에결합이용이하지않아전립선을싸고있는상피막을통과하기가어렵기때문으로생각한다. 이것이만성세균성전립선염의치료가어려운것이고, 치료시고용량, 장기간의항생제치료가필요한이유이다. 20,21 Fluoroquinolone은세포내액과세포외액에모두침투할수있기때문에전립선염의치료에우수한약제로알려져있다. 이러한이유때문에 fluoroquinolone을이용한약제인 ciprofloxacin은전립선염을유발하는병인에대해항균작용을하는약물로널리이용되고있다. 3 저자들의실험에서도 ciprofloxacin으로치료를시행한모델집단은세균배양에서집락수의의미있는감소와염증소견의개선을확인할수있었다. 그러나장기적인관점에서보았을때, 치료효과는 60% 정도로기대에미치지못하는것으로보고되고있다. 이의이유로 Nickel 등은감염에전립선내의환경의변화와전립선조직내의석회화가감염의원인이되는세균균주들을항생제로부터보호하기때문일것으로언급하였다. Ginsenoside는인삼에서얻어진추출물로, 이미그 antitumor effect에대해서는국내외의많은실험에서그효과가 입증된바있다. 22,23 또한최근들어 myocardial infarction 환자에게있어 myocardial cell regeneration 및항산화작용등의 positive effect와 24,25 chronic bacterial pneumonia 환자에게사용시 bacterial clearance rate의증가 4 등 cell regeneration 및 anti-inflammatory effect가보고되고있으며, 또한최근에는 prostate cancer에서 paclitaxel과함께사용하였을때, synergistic effect가있는것으로보고되었다. 22 Urovaxom R 은 18 Escherichia coli strains에서얻어진 immuno-stimulating component의 bacterial extract로서주로재발성요로감염에예방적으로쓰이고있다. 주로 interleukin-6 (IL-6), IL-10 등을통한 T 세포의면역기전에작용하여항염효과를나타내는것으로알려져있으며, 경구투여시재발성요로감염에효과를나타내는것으로보고되었다. 9,10 저자들은실험을통해전립선조직과요배양검사에서염증의호전이통계학적으로유의하지는않지만 ginsenoside를투여한실험군모델에서대조군모델에비해전립선염증의개선을확인하였으며, 세균배양결과에서도대조군모델에비해실험군모델에서세균의집락수가적게측정됨을확인하였다. 또한, Urovaxom R 을경구투여한실험군모델에서는대조군모델에비해전립선조직의미생물학적지표와조직학적지표가모두통계적으로의미있는개선을확인할수있었다. 이는 Urovaxom R 만을단독으로처리한군과, Urovaxom R 과 ciprofloxacin을병용투여한군을비교하였을때, 병용투여군에서더욱치료효과가좋은것으로확인되어 Urovaxom R 을항생제와함께복용시그상승효과를기대할수있을것으로예상한다. 전술한바와같이항생제의장기복용으로인한경제적부담이나, 항생제내성균의발전, 그리고약제장기복용으로인한부작용등여러원인으로항생제만의단독치료는어느정도의치료한계를가진다. 3 저자들은 ginsenoside와 ciprofloxacin의병용투여, 혹은 Urovaxom R 과 ciprofloxacin의병용투여가이러한항생제단독치료의한계를극복할수있을것이라고생각하였고이를실험을통해알아보고자하였으며, 실험결과 ginsenoside와 ciprofloxacin을병용투여한군에서세균수의의미있는감소와염증정도의개선을확인할수있었으나, 이를 ciprofloxacin 혹은 ginsenoside를단독투여한군과비교하였을때통계적으로의미있는차이는확인할수없었다. 이의이유로는실험에시행한동물의수가적어충분한양의자료가확보되지않았을가능성에무게를둘수있을것이다. 그이유로통계처리과정중확인된 ginsenoside와 ciprofloxacin의병용투여군과 ginsenoside 단독투여군, ciprofloxacin 단독투여군간의평균값의차이가매우높기때문이며, 비록본실험에서는통계적으로의미있는수치는얻지못했지만, 향후충분한실험이

8 856 대한비뇨기과학회지 : 제 48 권제 8 호 2007 다시행해진다면본실험과는다른조금더의미있는결과를얻을수있을것으로생각한다. 또한 Urovaxom R 단독투여군과 Urovaxom R 과 ciprofloxacin 병용투여군사이에서는통계학적으로의미있는차이를확인할수있었고, 이는만성세균성전립선염모델에서 ginsenoside와 ciprofloxacin, 혹은 Urovaxom R 과 ciprofloxacin의병용투여시상승효과를기대할수있으며, 향후만성세균성전립선염환자들의삶의질개선에효과적인대안이될수있을것으로생각한다. 결 만성세균성전립선염치료모델에있어본실험은 ciprofloxacin의단독투여, Urovaxom R 의단독투여및 ginsenoside 와 ciprofloxacin 혹은 Urovaxom R 과 ciprofloxacin의병용투여를비교해보았을때, ciprofloxacin의단독투여는만성세균성전립선염의치료에효과적이지만, ginsenoside와 ciprofloxacin을병용투여하였을때, 혹은 Urovaxom R 과 ciprofloxacin을병용투여하였을때만성세균성전립선염치료에더욱효과적이었음을확인할수있었으며, 이로인해향후재발의가능성을줄일여지가더높을것으로추측된다. 더나아가 ginsenoside 혹은 Urovaxom R 과 ciprofloxacin의병용투여는장기적인관점에서볼때, 항생제장기복용의필요기간을단축시킴으로써항생제부작용을줄이고세균내성을줄일수있다는점에서임상적으로유용할것으로생각되며이에대해서는향후지속적인연구가필요할것으로생각한다. 론 REFERENCES 1.
