摘要
目的:探讨法舒地尔(Fasudil)对敌敌畏中毒大鼠急性肺损伤时血浆肿瘤坏死因子α(TNF-α)和白细胞介素-6(IL-6)水平的影响。方法:Sprague Dawley大鼠30只,随机分成对照组、敌敌畏(dichlorvos,DDVP)中毒组、法舒地尔干预组3组,每组10只,均予以气管切开接呼吸机辅助通气。6h后留取血样用酶联免疫吸附分析(ELISA)法测血浆TNF-α、IL-6水平。取左肺下叶组织,HE染色观察病理学改变。结果:与对照组比,中毒组和干预组大鼠血浆TNF-α、IL-6水平均显著升高(P<0.01),肺组织HE染色有炎症细胞浸润;与中毒组比,干预组TNF-α、IL-6升高程度显著降低(P<0.05),肺损伤程度较轻。结论:法舒地尔能降低敌敌畏中毒大鼠血浆TNF-α、IL-6水平,能显著减轻肺损伤的病理损害,对大鼠敌敌畏中毒性急性肺损伤有明显的保护作用。
Objective:To investigate the effect of fasudil on acute lung injury in rats with Dichlorvos poisoning.Methods: 30 male Spragne-Dawley(SD) rats were randomized into the control group,Dichlorvos poisoning group and Fasudil pretreatment group(n=10each).Three groups were all supported with breathing machine connected with the tube from incision of trachea.tumor necrotic-α(TNF-α),and interleukin-6(IL-6) in blood serum were measured six hours later.Histomorphology of lung tissue was observered though HE stain.Results: Compared with the control group,the level of TNF-α and IL-6 of the other two groups were higher(P0.01).Compared with the poisoning group,the level of TNF-α and IL-6 were significant decreased in the pretreatment group(P0.05).The histological changes of lung injury in the pretreatment group were weakened.Conclusions: It showed that Fasudil could inhibit the level of TNF-α and IL-6 in serum of rats with acute Dichlorvos poisoning.It could also decrease the histomorphology of lung injury.The protective effection on acute lung injury in rats with Dichlorvos poisoning was obviously.
