氧化苦参碱对大鼠肝纤维化的影响

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。

Effects of oxymatrine on liver fibrosis in rats

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 (C), hyaluronate (HA), tumor necrosis factor alpha (TNF) 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, IVC, HA, and TNF were lower in the oxymatrinetreated rats than those in the oxymatrineuntreated 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.
