| 摘要: |
| 目的 研究虫草多糖抗小鼠肺纤维化的作用。方法 采用气管注射平阳霉素制作小鼠肺纤维化模型，酶联免疫吸附法测定血清白介素1受体抑制剂（interleukin-1 receptor antagonist，IL-1RA）含量，碱水解法测定肺组织中羟脯氨酸（hydroxyproline，Hyp）含量，Masson染色法观察肺组织胶原沉积情况。结果 与肺纤维化模型组相比，虫草菌粉组、虫草总多糖组和虫草多糖[分子量（molecular mass，MW）<2×105]组血清中IL-1RA水平明显升高，肺组织中Hyp含量明显降低；虫草总多糖组和虫草多糖（MW<2×105）组肺组织纤维化面积明显减小。结论 虫草多糖具有明显的抗小鼠肺纤维化作用。 |

| Abstract: |
| OBJECTIVE To study the effects of cordyceps polysaccharide on pulmonary fibrosis model of mice. METHODS The pulmonary fibrosis model of mice was established by intratracheal injection of pingyangmycin. The content of interleukin-1 receptor antagonist(IL-1RA) in serum was determined by ELISA, and the content of hydroxyproline(Hyp) in lung tissue was determined by alkali hydrolysis. Collagen deposition in lung tissue was observed by Masson staining. RESULTS Compared with the pulmonary fibrosis model group, the content of IL-1RA in serum of fermentation cordyceps powder group, total cordyceps polysaccharide group and cordyceps polysaccharide group[molecular mass(MW)<2×105] evidently increased, but the content of Hyp in lung tissue evidently decreased. The fibrosis area of total cordyceps polysaccharide group and cordyceps polysaccharide group(MW<2×105) evidently decreased. CONCLUSION The cordyceps polysaccharide have significant anti-pulmonary fibrosis effects on model mice induced by pingyangmycin. |
