Abstract

The aim of the present study was to investigate the preventive potential of pentoxifylline, atorvastatin and trans‑caryophyllene in oral mucositis through histopathological analysis of wounds in the oral mucosa of Wistar rats treated with 5‑FU, and to evaluate the immunomodulatory effect of these drugs on serum nitrite production, in situ IFN‑γ, TNF‑α and TGF‑β, and TNF‑α in tissues. A total of 32 male Wistar rats with an average age of 9 weeks and an average body weight of 250 g were divided into four treatment groups: Saline, trans‑caryophyllene, pentoxifylline and atorvastatin. Oral mucositis was then induced. On days 3 and 4, the mucosa of the mouth of eight pre‑treated animals in each group was bilaterally scarified twice with the tip of a sterile needle, with an anesthetic solution. Mucosal samples from animals treated with trans‑caryophyllene preserved a thin epithelial lining associated with focal perivascular inflammatory infiltrates. Pentoxifylline‑treated animals exhibited total epithelial loss in oral wounds with severe inflammatory infiltrates and mild re‑epithelialization associated with mild and diffuse inflammatory infiltrates. Samples from atorvastatin‑treated animals exhibited no epithelial dissolution, with preserved thin lining and mild diffuse inflammatory infiltrates. The analysis of TNF‑α expression revealed improved results in trans‑caryophyllene animals. The analysis of TGF‑β expression revealed positive mononuclear cells. Preventive treatment with atorvastatin was demonstrated to modulate the serum expression levels of TNF‑α during all stages of the experiment. Treatment with trans‑caryophyllene modulated serum IFN‑γ levels negatively, whereas treatment with atorvastatin and trans‑caryophyllene maintained lower levels of IFN‑γ compared with the control group.
