摘要 目的观察法舒地尔在急性百草枯(PQ)中毒大鼠肺组织的干预作用及对α-平滑肌肌动蛋白(α-SMA)表达的影响。方法将72只SPF级SD大鼠随机分成正常对照组、法舒地尔对照组、PQ中毒组及法舒地尔干预组,分别于灌胃后7、14、28d活杀大鼠留取标本。观察大鼠的行为学改变、HE和Masson染色观察大鼠肺组织病理改变,实时荧光定量PCR及免疫组化法检测α-SMA的表达水平。结果光镜下,PQ中毒组大鼠急性肺损伤和纤维化明显,法舒地尔干预组大鼠肺组织损伤程度较中毒组减轻。与正常对照组比较,PQ中毒组大鼠肺组织7、14、28dα-SMAmRNA及蛋白的表达量显著增高,于28d时达峰值,差异有统计学意义(均P<0.05);与同一时间PQ中毒组比较,法舒地尔干预组小鼠肺组织α-SMAmRNA及蛋白表达量明显降低,差异有统计学意义(P<0.05)。结论法舒地尔可以减轻百草枯所致大鼠肺纤维化程度,其可能是抑制α-SMA的表达实现的。
