Purpose: Since glycosaminoglycans plays an important role in the pathophysiology and treatment of interstitial cystitis, we hope to investigate the potential benefit of small molecular chitosan, which is the monomer of glycosaminoglycans, in the treatment of cyclophosphamide induced interstitial cystitis rat model.
 
Materials and Methods: We used cyclophosphamide (CYP) intraperitoneal injection to induced chronic cystitis in female rats. Treatment with intravesical chitosan instillation was performed along with cystitis induction. Cystometrogram was performed to evaluate intravesical pressure and intercontraction interval.
 
Results: There was significant difference in intravesical pressure and intercontraction interval when rats treated with chitosan. Systemic cytokines including IL-6 and TNF-a increased in CYP rats while IL-10 and IFN-r decreased. The trend is mildly reversed in IL-10 when intravesical chitosan was applied.
 
Conclusions: Chitosan may potentiate the effect of cyclophosphamide. Spleen cytokines changes indicated that locally applied chitosan may affect systemic response in rats. Intravesical chitosan had a role further more than a coating agent in bladder.
