This study was conducted to investigate the in vivo effect of a single intratracheal inoculation of Pasteurella haemolytica cytotoxin on the rat lung. Changes in the biochemical and cytological composition of bronchoalveolar lavage fluid were used to estimate the magnitude of pulmonary cell injury, inflammatory response, vascular permeability and functional status of pulmonary alveolar macrophages. Effect of treatment was compared with rats intratracheally inoculated with supernatants of Pasteurella multocida or with sterile physiological saline solution (vehicle). Results indicated that Pasteurella haemolytica supernatants were not significantly toxic for the lungs of rats.
本研究旨在探讨经气管内单次接种溶血巴斯德氏菌细胞毒素对大鼠肺部的体内作用。利用支气管肺泡灌洗液体生化和细胞学组成的变化来评估肺细胞损伤程度、炎症反应、血管通透性及肺泡巨噬细胞的功能状态。将治疗效果与经气管内接种多杀巴斯德氏菌上清液或无菌生理盐溶液(赋形剂)的大鼠进行比较。结果表明,溶血巴斯德氏菌上清液对大鼠肺部无明显毒性。
