Özet

The present study aimed to unveil the gastroprotective potential of Vaccinium macrocarpon (VM) extract and its mechanism of action against indomethacin (INDO)-induced gastric ulcers in rats. To achieve this goal, rats were pretreated with either omeprazole (20 mg/kg) or VM (100 mg/kg) orally for 14 consecutive days. Gastric tissue samples were collected and various parameters were evaluated to understand the mechanism of VM's action, including the levels of superoxide dismutase, malondialdehyde, glutathione, CAT and transforming growth factor beta (TGF-beta), as well as the mRNA expression levels of tumour necrosis factor alpha, interleukin 1 beta, nuclear factor kappa B (NF-kappa B) and inhibitor kappa B (I kappa B). Additionally, the immunopositivity of cyclooxygenase (COX)-1, COX-2, PGE2, proliferating cell nuclear antigen (PCNA) and caspase-3 was assessed. The total amount of phenolic compounds present in the VM extract was high (58.08 mu g/mL gallic acid equivalent/mg extract). The healing effect of VM was demonstrated by an increase in the expression of PCNA. Furthermore, the level of TGF-beta was found to increase upon treatment with VM. Analyses of COX-1, COX-2 and PGE2 expression in gastric tissue confirmed the gastroprotective effect of VM. Notably, the expression of NF-kappa B was markedly reduced, whereas that of I kappa B was substantially increased. Overall, the findings of this study demonstrate that VM extract has gastroprotective and curative effects against INDO-induced ulcers through its antioxidant, anti-inflammatory, mucosal regenerative and anti-apoptotic activities. Therefore, VM may serve as a useful adjuvant treatment for nonsteroidal anti-inflammatory drugs-induced gastric ulcer disease.
