中文摘要:

目的探索铜绿假单胞菌致大鼠肺炎模型的制备方法，为后续研究奠定实验基础。方法将Sprague-Dawley （SD）大鼠48只随机分为4组：A对照组、B气管注射组、C气管插管感染组和D滴鼻感染组。适应饲喂3 d后，分别给予不同造模干预，分别于干预后5、10和15 d动态监测各亚组大鼠体重、体温、白细胞数、肺组织病理学变化等。结果各模型组大鼠行为学表现、体重、体温、白细胞、肺组织炎症病理学表现均与对照组差异有显著性；②各模型组均证实为铜绿假单胞菌感染，对照组则阴性。结论经滴鼻途径以铜绿假单胞菌感染大鼠，可得到合格大鼠肺炎模型；此感染途径可避免手术创口带来的炎症反应干扰，简便易行，可推广。

英文摘要:

Objective To explore the preparation of a rat model of pneumonia model induced by Pseudomonas aeruginosa(PA) using different methods,and to lay the foundation for further studies.Methods 48 SD rats were randomly divided into 4 groups:the control group (A),the intratracheal injection group (B),the trachea cannulation group (C) and the intranasal inoculation group (D).After intervention with different treatment modalities,the body weight,temperature,white blood cell count and lung pathological changes in the rats of all groups were detected at 5,10,15 days.Results 1.The behavior,body weight,temperature,leukocytes and pathological inflammatory changes of the lung in rats of the model groups were significantly different from that of control group.2.Pseudomonas aeruginosa was detected in rats of all the model groups,but the control group was negative.Conclusions Rat model of Pseudomonas aeruginosa infected pneumonia can be successfully established by intranasal inoculation.This method can avoid the inflammatory interference from operation,and is simple and suitable for popularization.
