摘 要:AIM: To observe the anti-liver fibrosis effect of Astragalus complanatus fiavonoids (ACF) in rats. METHODS: The liver fibrosis model in rats was established by injecting interperitoneally 0.2 mL/100 g 0.5% dimethylnitrosamine, thrice a week. Meanwhile, the rats were administered ACF (30, 60, 120 mg/kg) or colchicine (0.1 mg/kg) once a day for 1 mo. Serum N-propeptide of type Ⅰ procollagen (PINP) and type Ⅲ procollagen (PⅢNP) was measured using ELISA. Malondialdehyde (MDA) and superoxide dismutase (SOD) in hepatic tissue were evaluated. Matrix metal protease-1 (MMP-1) mRNA expression was assayed by RT-PCR and the protein expression of tissue inhibitor of metal protease-1 (TIMP-1) was analyzed by immunohistochemistry. RESULTS: In the ACF groups, SOD activity increased and MDA content decreased in comparison to the liver fibrosis model group. The serum PINP and PⅢNP contents in ACF-2 and -3 group decreased compared to those in model group. In ACF-2 and -3 group, the expression of MMP-1 mRNA increased significantly and the protein expression of TIMP-1 decreased compared to that in model group. CONCLUSION: The antifibrotic mechanisms of ACF are associated with its influence on lipid peroxidation and collagen synthesis and degradation.瞄准:在老鼠观察距骨 complanatus flavonoids (ACF ) 的反肝纤维变性效果。方法:在老鼠的肝纤维变性模型被 interperitoneally 注射 0.2 mL/100 g 建立 0.5% dimethylnitrosamine,三次一个星期。同时,老鼠是管理 ACF (30, 60, 120 mg/kg ) 或用番红花作原料而制成的植物盐基(0.1 mg/kg ) 一次为 1 瞬间的一天。类型的浆液 N-propeptide 我职业人员骨胶原(PINP ) 和类型 III 职业人员骨胶原(PIIINP ) 用 ELISA 被测量。Malondialdehyde (MDA ) 和在肝的织物的超级氧化物歧化酶(草皮) 被评估。矩阵金属 protease-1 (MMP-1 ) mRNA 表示是由 RT-PCR 的 assayed,金属 protease-1 (TIMP-1 ) 的织物禁止者的蛋白质表示被免疫组织化学分析。结果:在 ACF 组,草皮活动增加了, MDA 内容与肝纤维变性模型组相比减少了。在 ACF-2 和 -3 组的浆液 PINP 和 PIIINP 内容在模型组与那些相比减少了。在 ACF-2 和 -3 组,显著地增加的 MMP-1 mRNA 的表示和 TIMP-1 的蛋白质表示在模型组与那相比减少了。结论:ACF 的 antifibrotic 机制每氧化和骨胶原合成和降级与它对类脂化合物的影响被联系。
