Deoxynivalenol (DON) is a common mycotoxin produced by Fusarium sp. in cereals and foods. Ingestion of contaminated foodstuffs can cause digestive disorders in various animals. Many researchers focus on its toxicity and the pathological damage and absorptive function in the intestines. However, the effect of DON on gastric function is still unclear. The objective of the current study was to evaluate the impact of DON on gastric secretion. Rats were gavaged with DON at the dose of 0, 1, 5, and 25 mg/kg of body weight (bw). Gastric fluids were gathered by pylorus ligation 0.5 h after DON exposure. The results indicate that the volume of gastric fluid decreased by 25, 51, and 61% compared with the control, respectively. The pH increased to 3.2, 3.81, and 6.65 in the 1, 5, and 25 mg/kg bw DON group, compared with the control (1.9). To examine the mucosal injuries, the stomach tissues were made into hematoxylin and eosin slides. Histopathology observations suggest that no mucosal lesions were observed until DON exposure at 25 mg/kg bw. Additionally, the gastrin secretion in the fluids and mRNA expression in tissues were determined by the radioimmunoassay and real-time PCR assay, respectively. The results indicated that both significantly decreased in DON-exposed rats compared with the control. Taken together, DON exposure reduced gastric secretion in rats. Low gastrin secretion and mRNA expression play a major role, unless mucosal lesions by high DON exposure are present.
