Therapeutic Effects of GGsTop® Gel in a Mouse Model of 5-Fluorouracil-induced Oral Mucositis With Reduced White Blood Cells.

BACKGROUND/AIM: In order to produce an animal model for oral mucositis induced by anticancer drugs, it is necessary to maintain an immunosuppressive state. We determined the optimal dose and frequency of 5-fluorouracil for a model mouse production. In addition, we used this model to investigate the effect of GGsTop® gelation on the therapeutic effect of oral mucositis.

MATERIALS AND

METHODS

Changes in body weight and white blood cell count were measured to determine the optimal dosing schedule. The therapeutic effect of GGsTop® gel using chitosan was evaluated by observing changes in the ulcer area for three weeks and measuring collagen and glutathione concentrations in oral mucosal tissue.

RESULTS

The optimal dose and frequency of 5-fluorouracil were found to be 50 mg/kg every four days. It was revealed that the therapeutic effect of GGsTop® was enhanced by gelation.

CONCLUSION

GGsTop® gel is suggested to be a promising formulation for the treatment of oral mucositis.
