摘要
观察栝蒌薤白汤对肺纤维化大鼠支气管肺泡灌洗液 (BALF)中层粘连蛋白 (LN)、Ⅲ型前胶原(PC Ⅲ )含量的影响。用平阳霉素复制大鼠肺纤维化模型后 ,用药组每天灌胃栝蒌薤白汤 ,2 8d后处死 ,观察各组大鼠肺病理组织学改变。结果 :模型组大鼠肺泡炎及纤维化程度、BALF中LN及PC Ⅲ含量均明显高于正常对照组及用药组 (P <0 0 5 )。说明栝蒌薤白汤能明显减轻平阳霉素所致的大鼠肺泡炎及纤维化程度 ,抑制BALF中LN、PC Ⅲ含量的增高。
The ffects of Gualouxiebai Decoction (GD) on the Levels of laminin (LN) and procollagen Ⅲ (PC Ⅲ) in the bronchio alveolar lavage fluid (BALF) were observed in the rat with pulmonary fibrosis. The rat model of pulmonary fibrosis was induced by pingyangmycin (bleomycin). The model rats were divided into the model group and drug treating group. The rats in the drug treating group were given GD by gastric perfusion for 28 days, and then executed for the histopathological observation. The results showed that the severity of alveolitis and pulmonary fibrosis was greater, and the levels of LN and PC Ⅲ in BALF were markedly higher in the model group than those in the rats in the drug treating group and normal control group ( P <0 05), which suggests that GD can obviously relieve the severity of alveolitis and pulmonary fibrosis, and inhibit the increase in the levels of LN and PC Ⅲ in BALF.
