摘要: 目的 研究黄芪总黄酮对肝硬化大鼠肝组织脂肪酸转位酶(FAT)和环氧化酶2表达水平的影响。方法 将53只SD大鼠随机分为正常组10只和肝硬化组43只,给予二甲基亚硝胺(DMN)腹腔注射4周造模。在实验第3周,将造模组大鼠随机分为模型组14只和黄芪总黄酮治疗组(小剂量组14只和大剂量组15只),治疗组给予相应剂量的药物灌胃4周。在实验结束时,处死大鼠,取肝组织行天狼猩红染色,部分肝组织抽提总RNA,采用Real time PCR法检测目标mRNA水平;采用Western blot法检测目标蛋白表达水平。结果 模型组大鼠肝组织胶原增多,而治疗组胶原纤维明显下降;模型组FAT mRNA 为(0.098±0.08),蛋白为(1.05±0.076),而小剂量黄芪总黄酮治疗组分别为(0.58±0.04)和(0.67±0.021),大剂量组分别为(0.45±0.07)和[(0.31±0.072),P均<0.01];模型组环氧化酶2 mRNA为(0.78±0.044),蛋白为(1.48±0.13),而小剂量黄芪总黄酮治疗组分别为(0.52±0.010)和(1.24±0.11),大剂量黄芪总黄酮治疗组分别为(0.28±0.049)和[(0.68±0.09),P均<0.01]。结论 黄芪总黄酮发挥抗大鼠肝纤维化作用可能与抑制脂肪酸转位酶和环氧化酶2表达有关。

Abstract: Objective To study the effect of total flavonoids of astragalus (TFA) on expression of fatty acid translocase and cyclooxygenase 2 in rats with DMN-induced liver cirrhosis. Methods Fifty-three male SD rats were allocated randomly into control group (n=10) and model group (n=43). Rats in model group were given DMN by intraperitoneal injection for 4 weeks. At the 3rd experimental week,the model rats were randomly divided into model group (n=14) and TFA treatment groups (n=14,at dose of 15 mg.kg-1 and n=15,at dose of 30 mg.kg-1). At the end of 4 week experiment,the rats were sacrificed,and liver samples were collected. Sirus red staining was performed in liver tissues. Total RNA of liver tissues were isolated with TRizol reagents,and real time PCR was adopted to determine fatty acid translocase and cyclooxygenase 2 mRNA and their protein expression by PCR and Western blot. Results Collagen staining in model group increased markedly,and staining in treatment groups decreased markedly;the fatty acid translocase mRNA in model group was (0.098±0.08) and its protein was (1.05±0.076),while in small dosage group were(0.58±0.04) and(0.67±0.021),respectively,and in large dosage group were (0.45±0.07) and [(0.31±0.072),respectively,both P<0.05];the cyclooxygenase 2 mRNA in model group was (0.78±0.044) and its protein was (1.48±0.13),while in small dosage group were (0.52±0.010) and (1.24±0.11),respectively,and in large dosage group were (0.28±0.049) and [(0.68±0.09),respectively, both P<0.01]. Conclusion The anti-fibrotic effect of TFA might be associated with the inhibition of fatty acid translocase and cyclooxygenase 2 in rats with DMN-induced liver cirrhosis.
