【摘要】 本文主要介绍丹参提取的有效单体(IH764-3)抗肺纤维化的实验研究。结果表明IH764-3治疗组动物的肺系数,羟脯氨酸,表面活性物质含量,FGF活性均明显低于模型对照组。电镜观察证实治疗组肺胶原形成细胞数量,炎性细胞渗出,胶原纤维和弹力纤维都较模型组明显减少,肺泡毛细血管和肺泡膈内小血管形态较正常,Ⅱ型肺泡上皮细胞的数量和形态较正常。以上结果证明IH764-3对博莱霉素诱致的肺炎、肺纤维化具有明显的预防和治疗作用。更多还原

【Abstract】 IH764-3, an effective component isolated from Salvae milliorrhize (a component of traditional Chinese medicine) was used against pulmonary fibr-osis in this study. The results indicated that in the treated group, lung coefficient, surfactant, hydroxyproline content and FGF activity were significantly lower than those in the model group. Electron microscopic observation confirmed that the pulmonary ultrastructure was improved remarkably in the treated group: the proliferation of collagen-forming cells and infiltration of inflammatory cells, collagen and elastic fibers were obviously less. All the results demonstrated that IH764-3 has prophylactic and therapeutic effects on the development of pneumonitis and pulmonary fibrosis.更多还原
