Abstract:

Although cisplatin is a potent anticancer drug, it instigates oxidative and pro-inflammatory reactions which poses significant and distressing clinical symptoms in patients including nausea and vomiting which is related to damage of the gastric mucosa. This study investigated the effects of vitamin C and/or L-carnitine on cisplatin-induced gastric mucosa damage in rat. The rats were allocated into groups (n=5): a control group received distilled water and treatment groups received cisplatin (CIP) alone, cisplatin followed by vitamin C, L-carnitine or their combination. Cisplatin treatment caused disruption of the gastric mucosa histoarchitecture and alter the mucus barrier function in the gastric mucosa. Moreover, stomach tissue from the CIP treated group had increased levels of oxidative stress markers, malondialdehyde and H2O2 levels, and decreased activity of the antioxidant enzymes superoxide dismutase, glutathione peroxidase, catalase, glutathione S-transferase and non-antioxidant enzyme, reduced glutathione level. These deleterious events were accompanied by upregulated levels of the pro-inflammatory cytokines, tumor necrosis factor-alpha, interleukin-1beta, and inflammatory infiltration markers, myeloperoxidase and inducible nitric oxide synthase (iNOS). However, administration of both vitamin C and L-carnitine, and not the either of the two showed additive effect in attenuating these toxic effects which were confirm histologically. In conclusion, the combined administration of vitamin C and L-carnitine, but not the single therapy, could prevent the adverse effects of cisplatin on gastric tissues.
