ABSTRACT
Abstract Oral mucositis is a common inflammatory complication among patients with cancer. This study evaluated the histopathological, stereological, and antioxidant markers of 2% eucalyptus extract in induced oral mucositis in male golden hamsters. In this animal study, oral mucositis was induced in 30 male golden 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 once daily on days 3 and 4. On days 14-17, 2% eucalyptus hydroalcoholic extract gel and Calendula officinalis extract gel groups were treated and then compared with a non-treated control group. The histopathological and stereological scores and the pouch content of malondialdehyde, as well as the activities of glutathione and myeloperoxidase in the pouch tissue, were evaluated. Histopathologic scores of oral mucositis were lower in the eucalyptus gel group than those of the calendula and control groups (p<0.05). Also, a lower malondialdehyde level and higher myeloperoxidase and glutathione activities were detected in the eucalyptus group in comparison to the calendula and control groups (p<0.001). The thickness of the mucosa and submucosa increased in the eucalyptus group. The numerical density of the fibroblast and the volume density of the collagen significantly increased in the eucalyptus group. In conclusion, the use of eucalyptus hydroalcoholic extract may be associated with reduced intensity of oral mucositis, diminished concentration of malondialdehyde, increased activity of myeloperoxidase and glutathione, increased volume of mucosa and submucosa, increased fibroblast and collagen in the induced oral mucositis in golden hamsters undergoing 5-FU consumption.
RESUMO
Resumo A mucosite oral é uma complicação inflamatória comum em pacientes com câncer. Este estudo avaliou os marcadores histopatológicos, estereológicos e antioxidantes de Eucalyptus 2% na mucosite oral induzida em hamsters dourados machos. Neste estudo em animais, a mucosite oral foi induzida em 30 hamsters golden masculinos por 5-FU (60 mg / kg) nos dias 0, 5 e 10 do estudo. A bolsa da bochecha foi arranhada com uma agulha estéril uma vez ao dia nos dias 3 e 4. Nos dias 14 a 17, os grupos de gel de eucalipto a 2% e curativos à base de gel foram tratados e comparados com um grupo controle. Foram avaliados os escores histopatológicos e estereológicos e o conteúdo de malondialdeído na bolsa, bem como as atividades de glutationa e mieloperoxidase no tecido da bolsa. Os escores histopatológicos de mucosite foram menores no grupo de gel de eucalipto a 2% do que os do gel e do grupo controle (p <0,05). Além disso, um nível mais baixo de malondialdeído e maiores atividades de mieloperoxidase e glutationa foram detectadas no grupo tratado com eucalipto em comparação aos grupos à base de gel e controle (p <0,001). A espessura da mucosa e submucosa aumentou no grupo Eucalyptus. A densidade numérica do fibroblasto e a densidade do volume do colágeno aumentaram significativamente nos grupos tratados com eucalipto. Em conclusão, o uso do extrato hidroalcoólico de Eucalyptus pode estar associado a menor intensidade de mucosite oral, diminuição da concentração de malondialdeído, aumento da atividade de mieloperoxidase e glutationa, aumento do volume de mucosa e submucosa, aumento de fibroblastos e colágeno na mucosite oral induzida em hamsters dourados em consumo de 5 UF.
