This study evaluated the efficacy of quercetin in mice with oral mucositis induced by 5-fluorouracil, showing that quercetin posttreatment led to fewer oral lesions and improved oxidative stress compared to pretreatment. It also had significant effects on the expression of inflammatory genes, suggesting that quercetin may improve the treatment process of oral mucositis induced by 5-fluorouracil.
The target of this study was to evaluate the efficacy, histopathological, oxidative stress, and molecular effects of quercetin (QRC) in mice with oral mucositis induced by 5-fluorouracil (5-FU). Thirty-six albino male mice with oral mucositis induced by 5-FU as a chemotherapeutic agent were used in this study. The animals were randomly divided into 6 groups: control group, mucositis (MUC) group, pretreatment group, posttreatment group, and two last groups including nanoemulsion form of QRC with a dose of 5 mg/kg in both pretreatment and posttreatment. In the present evaluation, fewer oral lesions were observed in the QRC posttreatment groups compared to the pretreatment and nanoemulsion receiving groups. In the SOD assay, the most significant difference was observed in the posttreatment nanogroup (41.073 +/- 1.24) and pretreatment nanogroup (43.453 +/- 2.60) in comparison to the 5-FU group (30.897 +/- 1.93). The results of CAT assay also showed a significant difference in nano-posttreatment (124.60 +/- 10.85), posttreatment (135.4 +/- 9.82), and nano-pretreatment groups (128.80 +/- 7.20) compared to the 5-FU group (55.07 +/- 8.91). The expression of inflammatory genes such as Hif-1 alpha and Nf kappa B in this group was lower than in the other groups, although this difference was not significant. It seems that the use of QRC can improve the treatment process of oral mucositis induced by 5-FU.
