Healing acceleration in hamsters of oral mucositis induced by 5-fluorouracil with topical Calendula officinalis.

OBJECTIVE

This study assessed the potential of topical Calendula officinalis extract on the healing of oral mucositis induced by 5-fluorouracil (5-FU) in hamsters.

STUDY

DESIGN

Oral mucositis was induced in 60 male hamsters by 5-FU (60 mg/kg) on days 0, 5, and 10 of the study. The cheek pouch was scratched with a sterile needle on days 1 and 2. On days 12-17, 5% and 10% C. officinalis gel and gel base groups were treated and then compared with a control group. Macroscopic and microscopic scores and weights were evaluated.

RESULTS

Microscopic and macroscopic scores of mucositis were lower in the 5% and 10% C. officinalis gel groups than in the gel base and control groups (P < .05). Weight gain was noted in the treatment groups compared with the gel base and control groups (P < .05).

CONCLUSIONS

Calendula officinalis extract accelerated the healing of oral mucositis in hamsters.
