Abstract:   目的观察小檗碱对流感病毒性肺炎小鼠肺组织中细胞间黏附分子-1(ICAM-1)、血管细胞黏附分子-1(VCAM-1)表达及炎性细胞渗出的影响,探讨其抗炎性损伤作用。方法 BALB/c小鼠108只随机分为正常组、模型组、小檗碱组。模型组和小檗碱组予25μL 50LD50病毒液滴鼻建立流感病毒感染的小鼠肺炎模型,感染后1 h,正常组和模型组予以双蒸水灌胃,小檗碱组每日予药物0.005 g/kg腹腔注射,各组均给药2次/d,连续给药5 d。感染后第2、4、6日分别取材,免疫组化法检测肺组织中 ICAM-1、VCAM-1的表达,对肺泡灌洗液(BALF)中白细胞进行分类计数。结果病毒感染后第2、4、6日,模型组肺组织中ICAM-1、VCAM-1的表达明显增强,小檗碱降低了ICAM-1、VCAM-1的表达水平,与模型组比较差异有统计学意义(P<0.01);模型组BALF中白细胞总数、单个核细胞数、嗜酸性粒细胞数、中性粒细胞数均明显升高,小檗碱组第6日BALF中白细胞总数、中性粒细胞数明显降低(P<0.01),第4日时BALF中单个核细胞数降低(P<0.01)。结论小檗碱能够抑制流感病毒性肺炎小鼠肺组织中ICAM-1、VCAM-1表达,减轻了炎性细胞渗出,对小鼠流感病毒性肺炎肺组织炎性损伤具有保护作用。
