【摘要】:目的:評價多巴胺和去甲腎上腺素對膿毒癥休克兔急性肺損傷的保護作用。方法:采用盲腸結扎穿孔(CLP)聯(lián)合靜脈注入內毒素的方法復制膿毒癥休克動物模型,將63只新西蘭大白兔分為假手術對照組(A組,n=7)、模型組(B組,n=14)、多巴胺治療組(C組,n=14)、去甲腎上腺素治療組(D組,n=14)、多巴胺聯(lián)合去甲腎上腺素治療組(E組,n=14),各組分別于造模后3、6 h處死7只。留取血清標本,用酶聯(lián)免疫吸附測定法(enzyme-linked immunosorbent assay,ELISA)檢測各時相點血清中肺泡表面活性蛋白A與肺泡表面活性蛋白D(surfactant protein A and surfactant protein D,SP-A and SP-D)的濃度值,并留取肺組織標本做光鏡和電鏡檢查。結果:各組血清中SP-A與SP-D的濃度值在各時相點均高于A組(P0.05);與B組比較,C組血清中SP-A與SP-D的濃度值在3、6 h差異均無統(tǒng)計學意義(P0.05);D、E組血清中SP-A與SP-D的濃度值在3、6 h均顯著低于B組(P0.05)。形態(tài)學觀察發(fā)現(xiàn)D、E組肺組織損傷明顯輕于B、C組。結論:膿毒癥休克時肺組織損傷嚴重;單獨應用去甲腎上腺素或聯(lián)合應用去甲腎上腺素和多巴胺可以有效減輕膿毒癥休克引起的肺組織損傷,對肺組織起保護作用。
[Abstract]:Aim: to evaluate the protective effects of dopamine and norepinephrine on acute lung injury in septic shock rabbits. Methods: septic shock model was established by cecal ligation and perforation combined with intravenous injection of endotoxin. 63 New Zealand white rabbits were divided into sham operation control group (group A), model group B (group B), dopamine group C (group C), noradrenaline group (group D), and dopamine plus norepinephrine treatment group (group E). 7 rats were killed at 6 hours after the model. Serum samples were collected and the concentrations of alveolar surfactant protein A and alveolar surfactant protein D(surfactant protein A and surfactant protein SP-A and SP-D were detected by enzyme-linked immunosorbent assaysa at different time points. The specimens of lung tissue were examined by light microscope and electron microscope. Results: the concentration of SP-A and SP-D in serum of each group was higher than that of group A at each time phase, and the concentration of SP-A and SP-D in group C was not significantly different from that in group B at 3h. There was no significant difference in the concentration of SP-A and SP-D between group A and group C at 36 h. All of them were significantly lower than group B (P 0.05). Morphological observation showed that the lung tissue injury in DU E group was significantly lighter than that in BU C group. Conclusion: the lung tissue injury is serious in septic shock and norepinephrine alone or combined with norepinephrine and dopamine can effectively attenuate the lung tissue injury induced by septic shock and play a protective role in the lung tissue.
