| 摘要: |
| 目的：探讨氧化苦参碱对实验性肝损伤肝胶原合成度及纤维化的影响。方法：采用CCl4造成大鼠慢性肝损伤肝纤维化模型，同时用氧化苦参碱防治，并动态观察血清丙氨酸氨基转移酶（ALT）、Ⅳ型胶原（Ⅳ-C）、透明质酸（HA）、肿瘤坏死因子-α（TNFα）的水平及肝组织病理变化，通过计算机图像分析系统分析肝内纤维组织增生情况。结果：氧化苦参碱治疗组血清ALT，Ⅳ-C，HA，TNFα水平及肝组织内炎症活动度、纤维组织增生程度均低于模型组，且大剂量治疗组又低于小剂量治疗组。结论：氧化苦参碱有减轻肝脏炎症活动度、抑制肝内胶原合成度及抗肝纤维化作用。 |

| Abstract: |
| Objective： To evaluate the effects of oxymatrine on liver fibrosis. Methods: Chronic liver damage and liver fibrosis in rats were induced by hypodermically injecting carbon tetrachloride (CCl4) twice a week for 12 weeks, and were simultaneously treated intraperitoneally with oxymatrine once a day. The levels of serum alanine aminotransferase (ALT), type IV collagen (Ⅳ-C), hyaluronate (HA), tumor necrosis factor alpha (TNFα) were detected at various times, and the degrees of inflammatory activity and fibrogenesis in liver tissues were also observed. Results: The levels of serum ALT, IV-C, HA, and TNFα were lower in the oxymatrine-treated rats than those in the oxymatrine-untreated ones, and so were the degrees of inflammatory activity and fibrogenesis in liver tissues. Conclusion: Oxymatrine can inhibit the inflammatory activity and fibrogenesis in liver tissue. |
