摘要:

目的 探讨当归多糖对麻黄素致肝损伤的保护作用。 方法 72只小鼠分为正常对照组、实验对照组、当归多糖1组和当归多糖2组4个组,实验对照组和当归多糖组连续腹腔注射0.2ml浓度为4.0g/L麻黄素溶液15d(每天2次),正常对照组注射等量生理盐水,当归多糖1组和2组在腹腔注射麻黄素溶液1h后,灌胃0.3ml(12.5g/L、25.0g/L)当归(粗)多糖溶液,正常对照组和实验对照组灌胃等量的生理盐水。分别于5、10、15d用光学显微镜技术观察各组小鼠肝组织结构的变化,用比色法检测小鼠血浆γ-谷氨酰转移酶(γ-GT)、碱性磷酸酶(AKP)、谷丙转氨酶(ALT)、谷草转氨酶(AST)及肝组织超氧化物歧化酶(SOD)活性和丙二醛(MDA)含量的变化,用免疫组织化学方法检测小鼠肝组织Bax蛋白、Csapase-3蛋白表达的变化。 结果 实验对照组小鼠肝组织有不同程度的损伤,肝细胞索排列紊乱,肝细胞疏松,肝血窦扩张,血浆γ-GT、AKP、ALT、AST活性明显升高,肝组织SOD活性显著降低,MDA含量显著升高,Bax、Caspase-3蛋白的表达显著升高;当归多糖组小鼠肝组织病理损伤明显减轻,血浆γ-GT、AKP、ALT、AST活性明显降低,肝组织SOD活性明显升高,MDA含量显著降低,Bax、Caspase-3蛋白的表达有所降低。 结论 当归(粗)多糖可提高肝组织细胞的抗氧化能力,抑制细胞凋亡,促进组织细胞损伤修复,对麻黄素致肝损伤具有一定的保护作用。

Abstract:

Objective To investigate the protection of Angelica sinensis polysaccharide(ASP) on ephedrine induced hepatic injury in mice. Methods Seventy-two mice were randomly divided into 4 groups:the natural control group,experiment control group,ASP1 group, and ASP2 group.The experimental control group and ASP groups were intraperitoneally injected with a 4.0g/L of ephedrine 0.2ml twice a day for 15 days, and the natural control group was injected with a same amount of saline.The ASP groups were irrigated to stomach with 0.3ml Angelica sinensispolysaccharide solution (12.5g/L,25.0g/L)1 hour after ephedrine injection,the natural control group and experiment control group were irrigated to stomach with a same amount of saline.The mice were sacrificed at 5 day,10day,and 15 day after treatment,respectively.The morphological observation was used to observe pathological changes of hepatic tissues.Activities of hepatic histologicalsuperoxide dismutase(SOD)and plasma γ-glutamyltransferase(γ-GT), alkaline phosphatase (AKP), glutamic-pyruvic transaminase (ALT), glutamic-oxalacetic transaminase(AST),as well as content of malonaldehyde(MDA)were detected by colorimetry.The expressions of Bax protein and Caspase-3 protein were measured by immunohistochemistry in liver of mice. Results There were various degree damages in hepatic tissues,hepatic cords were disorganized,liver cells were loose and liver sinusoid expanded,the activity of γ-GT、AKP、ALT、AST in plasma were significantly increased,the activity of SOD in liver tissue was significantly reduced,the content of MDA in liver tissue was increased significantly,the expression of Bax and Caspase-3 protein in liver were significantly increased.Compared with the experimental control group,pathological damage of liver was significantly improved,the activity of plasma γ-GT, AKP, ALT, AST were significantly reduced,the activity of SOD in liver tissue was increased significantly,however the content of MDA was significantly decreased and the expressions of Bax and Caspase-3 protein in liver were reduced in Angelica sinensis polysaccharide group. ConclusionAngelica sinensis polysaccharide can improve liver tissue antioxidant capacity and promote reparation of cell injury and protect hepatic injury which is induced by ephedrine.
