摘要: 目的: 研究苦参碱对肺间质纤维化 大鼠的保护作用。方法: 采用气管内灌注博来霉素(BLM)的 方法建立大鼠 肺纤维化模型,设正常对照组、模型组、小剂量苦参碱组(50 mg/kg)、大剂量苦参威组(100 mg/kg)和氢化可的松组(100 mg/kg),每组 18只,再各分为d7、14 和d28 组。观察各组不同时期病理切片和肺组织在脯氨酸(HYP)浓度,测定肺组织丙二醒(MDA)和谷肮甘肤过氧化物酶(GSHPX)含量。结果: 苦参碱组和氢化可的松组的肺泡炎和肺纤维化程度及 HYP 含量显著地低于模型组(P < 0.05);苦参碱和氢化可的松能明显降低肺间 质纤维化大鼠肺组织MDA水平,提高GSH-PX含量(P < 0.01)。结论: 苦参碱能减轻 BLM 诱导的大鼠肺纤维化,这种作用有可能通过改善肺间质纤维化大鼠体内氧化应激状态实现。

Abstract: AIM: To study the effect of matrine on bleomycin-induced pulmonary fibrosis in rats and its mechanism. METHODS: Pulmonary fibrosis model was estalished in male Wistar rats by intratracheal instillation of bleomycin (BLM). Then the rats were given matrine by the intraperitoneal injection. Histological changes of the lungs were evaluated by HE stain and Masson's trichrome stain. Collagen content of the lung tissue was assessed by hydroxyproline concentration. Malondialdehyde (MDA) and glutathione peroxidase (GSH-PX) of the lung tissue were measured by colorimetric method. RESULTS: Pulmonary fibrosis of matrine group (OM) and hydrocortisone group (P) was improved as compared with that of group BLM. Hydroxyproline concentrations of up (OM) and group were lower than that of group BlM (P < 0. 05); The levels of MDA in the lung tissue were significantly increased in group OM and group P as compared with group BlM (P < 0.01). Therapeutic efficacy of the matrine was the same as the treatment of hormone in the rat model of bleomycin-induced pulmonarγfibrosis. CONCLUSION: Matrine alleviates bleomycin-induced pulmonary fibrosis in rats, which reated to the effectively inhibition of oxidative stress in lung tissues.
