摘要:
以抗性淀粉(RS2)为研究对象,构建动物模型,通过酶联免疫法、逆转录-聚合酶链式反应等方法研究其对HCl-乙醇诱导SD大鼠胃损伤的预防效果。结果表明:10% RS2、15% RS2和20% RS2均能降低大鼠的血清IL-6和TNF-α水平,大鼠的胃损伤程度,显著提高胃损伤的抑制率,均能减少胃液分泌量、增加胃液pH值,表现出一定的胃损伤预防效果。其中20% RS2对胃损伤预防效果最佳。

Abstract:
Rats were fed on a basal diet supplemented different levels of high-amylose corn starch (Hylon Ⅶ) to explore the effect of resistant starch on hydrochloric acid/ethanol-induced gastric lesions in rats using ELISA and reverse transcription- PCR (RT-PCR). The results showed that 10% RS2, 15% RS2 and 20% RS2 groups could reduce serum IL-6 and TNF-α levels and gastric lesion area, and significantly increase the inhibition rate of gastric lesions when compared with the stomach injury control group. In addition, these three concentrations of RS2 could decrease the secretion of gastric juice, and increase gastric pH. These results suggest that RS2 at the three concentration levels has a significant preventive effect on hydrochloric acid/ethanol-induced gastric lesions in rats and 20% RS2 is the most effective level.
