摘要: 目的:探究分心木提取物预处理对大鼠肝缺血-再灌注损伤(HIRI)的保护作用。方法:将30只SD雄性大鼠随机分为空
白组(S组)、缺血-再灌注组(I/R组)和给药组(DJ组),每组10只。DJ组进行分心木提取物给药干预,S组、I/R组给予等量0.9%
氯化钠溶液。14 d后,建立大鼠HIRI模型,S组除外。24 h后取材检测缺血组织肝功能及生化指标,并通过苏木精-伊红染色
观察肝组织病理变化。结果:与S组比较,I/R组肝组织中AST、ALT和XOD活力升高(P < 0.01),MDA、Hcy和NO的含量均升高
(P < 0.05或P < 0.01),SOD和GSH-Px水平降低(P < 0.01),荧光显微镜下观察I/R组大鼠肝细胞明显变性、坏死,而经给药预
处理的DJ组上述情况均有不同程度改善。结论:分心木乙酸乙酯提取物预处理对大鼠HIRI具有一定的抗氧化保护作用。

Abstract: Objective: To explore the protective effects of Diaphragma juglandis Fructus extract pretreatment on rat hepatic ischemiareperfusion
injury(HIRI). Methods: 30 SD male rats were randomly divided into the sham operation group(S group), the ischemiareperfusion
group(I/R group)and the drug treatment group(DJ group), with 10 rats in each group. The DJ group was given the
administration intervention of the extracts of Diaphragma juglandis Fructus, and the S, I/R groups were given the same volume of 0.9%
sodium chloride solution. After 14 days, a rat HIRI model was established, except for the S group. After 24 hours, samples were taken to
detect the liver function and biochemical indexes of ischemic tissue, and the pathological changes of liver tissue were observed by
hematoxylin-eosin staining. Results: Compared with S group, the activities of AST, ALT and XOD in liver tissues of I/R group increased
(P < 0.01), the contents of MDA, Hcy and NO increased(P < 0.05 or P < 0.01), while SOD and GSH-Px levels decreased(P < 0.01).
Observed under a fluorescence microscope, the rat liver cells in the I/R group were obviously degenerated and necrotic, while the abovementioned
conditions in the DJ group pretreated by the administration were improved to varying degrees. Conclusion: The pretreatment
of the ethyl acetate extract of Diaphragma juglandis Fructus has a certain antioxidant effects on HIRI in rats.
