摘要/Abstract

摘要： 为研究紫穗槐蜂蜜对小鼠急性酒精性胃溃疡的预防作用，本实验采用紫穗槐蜂蜜对小鼠连续灌胃10 d，随后通过灌胃体积分数65%的乙醇溶液诱导小鼠急性酒精性胃溃疡损伤。通过观察小鼠胃组织病理结构、测定溃疡指数，分析紫穗槐蜂蜜对小鼠胃组织的保护作用；通过测定氧化应激和炎症因子相关生化指标，评价紫穗槐蜂蜜对急性酒精性胃溃疡小鼠胃组织抗氧化和抗炎能力的影响。结果显示：紫穗槐蜂蜜可以有效保护胃黏膜的完整性，显著缓解乙醇摄入引起的超氧化物歧化酶活性和还原型谷胱甘肽含量的降低，显著抑制丙二醛的过量生成（P＜0.05）；与模型组相比，紫穗槐蜂蜜处理组小鼠胃组织中一氧化氮和前列腺素E2含量显著升高（P＜0.05），肿瘤坏死因子α含量显著降低（P＜0.05）。免疫组织化学及实时荧光核酸定量检测分析结果表明，紫穗槐蜂蜜能够显著抑制胃溃疡相关炎症因子蛋白和基因的表达（P＜0.05）。结论：紫穗槐蜂蜜能够通过保护机体胃黏膜、调节氧化应激和炎症因子表达等途径预防酒精性胃溃疡。

Abstract: To estimate the gastroprotective effect of Amorpha fruticosa L. honey (AFH) against ethanol-induced acute gastric ulcer, mice pretreated with AFH via oral gavage for 10 days were administered with 65% ethanol to induce acute gastric ulcer injury. The effect of AFH on the gastric pathological morphology and ulcer index of mice was analyzed, and its effect on gastric antioxidant and anti-inflammatory capacity in mice with acute alcoholic gastric ulcer was explored by the determination of biochemical indexes of oxidative stress and inflammatory cytokines. The results revealed that AFH protected the integrity of gastric mucosa, and alleviated the decrease in superoxide dismutase activity and glutathione content as well as the accumulation of malondialdehyde caused by ethanol consumption significantly (P < 0.05). Compared with the model control group, the AFH-treated mice showed significantly higher contents of prostaglandin E2 and NO (P < 0.05), but significantly lower content of tumor necrosis factor α in the gastric tissue (P < 0.05). The results of polymerase chain reaction and immunohistochemical analysis revealed that AFH significantly down-regulated the gene and protein expression of ulcer-related pro-inflammatory cytokines (P < 0.05). Taken together, AFH has a potential gastroprotective effect on ethanol-induced gastric ulcer by protecting the gastric mucosa from ethanol-induced damage and regulating oxidative stress and the expression of inflammatory cytokines.

Key words: Amorpha fruticosa L. honey; ethanol-induced acute gastric ulcer; oxidative stress; preventive effect
