摘要:

探究火龙果(Hylocereus undatus)对果蝇肠道损伤的缓解作用及可能的作用机制,以期为火龙果的开发和应用提供理论依据。利用葡聚糖硫酸钠(dextran sulfate sodium salt,DSS)诱导野生型黑腹果蝇(Drosophila melanogaster)急性肠道损伤模型,分析喂食正常培养基与含不同浓度(0.5%、1%、5%)火龙果的培养基对果蝇生存指标(爬行能力、活跃度和生存率)、抗氧化指标[超氧化物歧化酶(superoxide dismutase,SOD)、过氧化氢酶(catalase,CAT)、还原型谷胱甘肽(glutathione,GSH)、丙二醛]和肠道损伤情况(蓝精灵实验、乳酸脱氢酶(lactate dehydrogenase,D-LDH)、Ca2+含量)的影响。结果表明,通过DSS成功构建了果蝇急性肠道损伤模型;喂食含火龙果的培养基后,果蝇的生存率、爬行能力和活跃度有明显改善,超氧化物歧化酶活性、过氧化氢酶活性、乳酸脱氢酶活性和还原型谷胱甘肽含量上升,Ca2+和丙二醛含量下降,肠道损伤得到明显缓解,且高浓度组(含5%火龙果)作用效果最为显著。火龙果对DSS诱导的果蝇肠道损伤具有一定的缓解作用,这可能与火龙果作用于肠道细胞的损伤修复,增强抗氧化能力有关。

Abstract:

The study aims to investigate the alleviating effect of Hylocereus undatus on the intestinal damage in fruit flies, and explore the possible mechanism, with the goal of providing theoretical basis for the development and application of H. undatus. An acute intestinal injury model of wild-type Drosophila melanogaster was induced by dextran sulfate sodium salt (DSS). The effects of feeding normal medium and medium containing different concentrations (0.5%, 1%, 5%) of H. undatus on the survival indicators (locomotor ability, activity and survival rate), antioxidant indicators (superoxide dismutase, catalase, reduced glutathione, malondialdehyde), and intestinal injury conditions (smurf assay, lactate dehydrogenase, Ca2+ content determination) of Drosophila melanogaster were analyzed. The results showed that the acute intestinal injury model of Drosophila melanogaster was successfully constructed by DSS. After feeding with medium containing H. undatus, the survival rate, locomotor ability and activity of Drosophila melanogaster were significantly improved, the activities of superoxide dismutase, catalase and lactate dehydrogenase and the content of reduced glutathione increased, while the contents of Ca2+ and malondialdehyde decreased, and the intestinal injury was significantly alleviated. Moreover, the high concentration group (containing 5% H. undatus) had the most significant effect. H. undatus has an alleviating effect on the intestinal injury induced by DSS in Drosophila melanogaster, which may be related to the repair of intestinal cell damage and the enhancement of antioxidant capacity by H. undatus.
