The present study aims to investigate the gastroprotective effect of oil emulsion (BJOE) in animals. Gastroprotective potential of BJOE was studied on absolute ethanol, aspirin, reserpine and restraint plus water immersion-induced gastric ulcers in mice as well as glacial acetic acid (GAA) and pyloric ligation (PL)-induced gastric ulcers in rats. Except for ulcer scores, total acidity as well as pepsin activity as for the PL-induced gastric ulcer model and ulcer incidence as for the GAA-induced gastric ulcer model were also determined. Histopathological evaluation as for aspirin, reserpine, PL-induced models was conducted. Results showed that BJOE significantly ( < 0.05) reduced ulcer index in the mouse and rat models in a dose-dependent manner. It had significant ( < 0.05) suppressive effect on total activity of gastric juice as well in PL-induced model. Histopathological examination for the stomach samples confirmed the findings in the aspirin, reserpine or PL-induced gastric lesion models, which showed relatively complete mucosa structure and less inflammation. It is concluded that BJOE could be effective on gastric ulcer in rodents and its gastroprotective activity might be related to antioxidant, anti-inflammatory ability and promote gastric mucus secreted. The results may provide beneficial basis for increasing BJOE's clinical indication in future.
本研究旨在探讨油乳剂(BJOE)对动物的胃保护作用。研究了BJOE对小鼠由无水乙醇、阿司匹林、利血平以及束缚加浸水诱导的胃溃疡,以及大鼠由冰醋酸(GAA)和幽门结扎(PL)诱导的胃溃疡的胃保护潜力。除溃疡评分外,还测定了PL诱导的胃溃疡模型的总酸度以及胃蛋白酶活性,以及GAA诱导的胃溃疡模型的溃疡发生率。对阿司匹林、利血平、PL诱导的模型进行了组织病理学评估。结果表明,BJOE以剂量依赖性方式显著(<0.05)降低了小鼠和大鼠模型中的溃疡指数。在PL诱导的模型中,它对胃液的总活性也有显著(<0.05)的抑制作用。对胃样本的组织病理学检查证实了阿司匹林、利血平或PL诱导的胃损伤模型中的结果,显示黏膜结构相对完整且炎症较少。结论是,BJOE对啮齿动物的胃溃疡可能有效,其胃保护活性可能与抗氧化、抗炎能力以及促进胃黏液分泌有关。该结果可能为未来增加BJOE的临床适应证提供有益依据。
