本研究观察出血性低血压犬内引起肺部组织病理变化的体液因子能否转移至其它犬。方法:杂种犬40头,静脉麻醉后气管插管。全部犬实验前均有贫血,平均血细胞压积33％。测动脉压及中心静脉压。实验结束处死前,快速开胸切除肺叶,按Moss方法用灌注液行支气管及动脉内灌注,共30分钟。自肉眼正常部位取4个标本,浸入4℃灌注液2小时,脱水染色后行光学显微镜及电镜检查。犬分4组,每组10头。A组为对照组,
This study was to observe whether humoral factors that cause pathological changes in lung tissue in dogs with hemorrhagic hypotension can be transferred to other dogs. Methods: 40 hybrid dogs, tracheal intubation after intravenous anesthesia. All dogs had anemia before the experiment, with an average hematocrit of 33%. Measure arterial pressure and central venous pressure. Before the end of the experiment, the thoracotomy was performed by rapid thoracotomy, followed by bronchial and intra-arterial perfusion with perfusion fluid for 30 minutes according to the Moss method. Four specimens were taken from the normal part of the eye, immersed in 4 ℃ perfusion fluid for 2 hours, and stained with light microscope and electron microscope. Dogs divided into 4 groups, each group of 10. A group as control group,
