动态灌注与静态保存对犬离体肺组织中AQP1表达的影响
Effect of dynamic perfusion and static preservation on expression of AQP1 in vitro dog lung tissue
摘要
Abstract
Objective By comparing the change of expression of AQP1 in vitro lung preserved by the continuous infusion of a heart‐lung machine ,continuous pressure perfusion and single low temperature ,to explore the best method of vitro lung preserva‐tion .Methods Thirty Mongrel dogs were randomly divided into 3 groups ,and both lungs were completely resected under the condi‐tion of keeping mechanical ventilation .The vitro lungs were preserved by the way of the continuous infusion of a heart‐lung ma‐chine ,continuous pressure perfusion and single low temperature ,and collecting specimens according to the time point .HE staining was used to observe the morphological changes of vitro lung tissue .Immunohistochemistry and Western blot were used to detect the expression of AQP1 in vitro lung .Results HE staining found that as the time went by alveolar structure gradually collapsed ,in‐flammatory cells increased ,alveolar interval also gradually broadened and exudation could be seen in the alveolar cavity ;at the same time point ,organization structure of extracorporeal circulation group changed lighter than pressure perfusion group and low‐temper‐ature preservation group .In each experimental group ,the expression of AQP1 showed a trend of decline;at each time point ,the ex‐pression of AQP1 in extracorporeal circulation group was higher than pressure perfusion group ,and pressure infusion group was higher than that of low‐temperature preservation group .Conclusion The protective effect of the continuous infusion of a heart‐lung machine on vitro lung was better than continuous pressure perfusion and single low temperature .关键词
