摘要: 目的:探讨云木香乙醇提取物(ethanol extract of costusroot, EEC)对胃溃疡模型大鼠胃黏膜的影响及相关机制。方法:将SD大鼠随机分组:正常组、模型组、硫糖铝组、EEC低、高剂量组,除正常组外其余各组大鼠灌胃无水乙醇复制胃溃疡模型。观察各组大鼠胃溃疡面积变化并计算溃疡抑制率;HE染色法观测胃组织病理形态学改变;采用免疫组化法(immunohistochemisty, IHC)和Western blot法检测胃溃疡大鼠胃组织中Bax、Bcl-2蛋白的表达水平。结果:EEC能有效抑制模型大鼠溃疡面积的形成,减轻乙醇引起的胃组织病理学损伤;上调胃溃疡大鼠胃组织中Bcl-2蛋白表达(P<0.01),有效抑制乙醇引起的Bax蛋白过量表达(P<0.01)。 结论:EEC具有良好的抗胃溃疡作用,其作用机制可能与调节Bax、Bcl-2蛋白表达水平抑制胃黏膜细胞凋亡有关。

Abstract: AIM: To explore the effect of ethanol extract of costusroot (EEC) on gastric mucosa in gastric ulcer rats and related mechanism. METHODS: The rats were randomly divided into 5 groups: normal group, model group, sucralfate group, low-EEC group and high-EEC group, and anhydrous alcohol was administrated intragastrically to replicate gastric ulcer model in groups other than the normal. Changes in the area of gastric ulcer were observed and the inhibition rate of ulcer was calculated. The pathological changes of gastric tissue were measured by HE staining, and the protein expression levels of Bax and Bcl-2 were tested by immunohistochemistry and Western blot. RESULTS: EEC inhibited the formation of ulcer area in model rats and alleviated the histopathological damage to the stomach caused by ethanol. While enhancing the expression of Bcl-2 protein (P<0.01), it effectively inhibited the overexpression of Bax (P<0.01). CONCLUSION: EEC has a strong function of anti-gastric ulcers, and its mechanism of action might be related to the regulation of the protein expression level of Bax and Bcl-2 to inhibit the apoptosis of gastri mucosal cells.
