摘要
目的:探讨蒲地蓝消炎口服液(PDL)对脂多糖(LPS)导致的大鼠急性肺损伤的影响及作用机制。方法:72只Wistar大鼠,按体质量随机分为空白组,模型组,地塞米松组,PDL 7,3. 5,1. 75 g·kg~(-1)·d~(-1)组。模型组,地塞米松组,PDL 7,3. 5,1. 75 g·kg~(-1)·d~(-1)组雾化吸入LPS制备大鼠急性肺损伤模型。检测各组大鼠肺泡灌洗液(BALF)中白细胞总数,酶联免疫吸附测定(ELISA)检测肺组织中核转录因子-κB(NF-κB),白细胞介素-10(IL-10)的含量,苏木素-伊红(HE)染色观察肺组织形态学改变,探讨不同剂量PDL对急性肺损伤大鼠的影响。结果:与模型组比较,PDL 7,3. 5 g·kg~(-1)·d~(-1)组BALF中白细胞总数明显降低(P <0. 05); PDL 7,3. 5,1. 75 g·kg~(-1)·d~(-1)组NF-κB表达量明显降低(P <0. 05); PDL 3. 5 g·kg~(-1)·d~(-1)组IL-10表达量明显升高(P <0. 05); PDL 7 g·kg~(-1)·d~(-1)组肺组织中炎症反应减轻,水肿、瘀血等病理改变明显缓解(P <0. 05)。结论:PDL对急性肺损伤模型具有保护作用,可减轻大鼠急性肺损伤模型中肺组织的炎症反应,其机制与NF-κB,IL-10的表达相关,对肺组织的病理损伤有修复作用。
Objective: To explore the effect and mechanism of Pudilan Xiaoyan oral liquid( PDL) on the acute lung injury rat induced by lipopolysaccharide( LPS). Method: The 72 Wistar rats were randomly divided into control group,model group,dexamethasone group,PDL 7,3. 5,1. 75 g·kg~(-1)·d~(-1) group according to body weight. The acute lung injury model was made through inhalation with lipopolysaccharide in the model group,hexadecadrol group,PDL 7,3. 5,1. 75 g·kg~(-1)·d~(-1) group. To examining each rat alveolar lavage fluid( BALF) of the total number of white blood cells,enzyme-linked immunosorbent assay( ELISA) was used to detect the levels of nuclear transcription factors-kappa B( NF-κB) and interleukin~(-1)0( IL-10). Hematoxylin-eosin( HE) staining was used to observe morphological changes of lung tissue and explore different doses of PDL effect on acute lung injury in rats. Result: Compared with model group,the account of leukocyte in BALF decreased significantly in PDL 7 g·kg~(-1)·d~(-1) group and PDL 3. 5 g·kg~(-1)·d~(-1) group( P < 0. 05). The expression of NF-κB significantly decreased in PDL 7,3. 5,1. 75 g·kg~(-1)·d~(-1) group( P < 0. 05). And the expression of IL-10 significantly increased in PDL 3. 5 g·kg~(-1)·d~(-1) group( P < 0. 05). In PDL 7 g·kg~(-1)·d~(-1) group,the inflammation,edema and congestion in lung tissue reduced( P < 0. 05). Conclusion: PDL has a significant protective effect on the inflammation of acute lung injury model,and its mechanism is related to the expressions of NF-κB and IL-10. PDL could also repair the injury of lung in acute lung injury model.
