Abstract

Background and Objectives: 5-Fluorouracil (5-FU) is a commonly used drug in carcinomas of the head and neck. Mucositis and bone marrow toxicity are the two major side effects. Some initial studies showed that the local use of allopurinol as
a
mouthwash may reduce the oral mucositis caused by the admistration of 5-FU. The purposes of this study were to establish the stomatotoxicity of the chemotherapeutic agent in an animal model and to evaluate the effect of allopurinol mouthwaches in
treating mucositis objectively. Materials and Method: Young male Golden Syrian hamsters were used. The combination of three intraperitoneal injection of 5-FU at five-day intervals and superficial mechanical mucosal irritation were applied
and
examined with a gross, light microscope, and a scanning electron microscope. The allopurinol oral mucosal paintings were applied three times everyday, starting with the treatment of 5-FU, only at the right buccal mucosa for one minute.
Results:
Light microscopic changes were characterized by ulcer and inflammatory cells infiltration. The scanning electron microscopic examination showed irregular microridges and pits. Gross and histopathologic alterations were reliably reduced in the
allopurinol mucosal painting group. Conclusion: This study suggests an effective animal model for stomatotoxicity of chemotherapeutic agents, and that allopurinol mouthwashes can be effective in treating or protecting the 5-FU induced
stomatitis.
