评估老鼠在羰基氯、含全氟异丁烯的氟塑料热降解产物和二氧化氮中毒潜伏期气血屏障水通道成分(水通道蛋白-1、水通道蛋白-5、上皮钠通道)的动态变化。在中等致死浓度下,模拟了老鼠对羰基氯、含全氟异丁烯的氟塑料热降解产物和二氧化氮的中毒情况。接触后30分钟和60分钟,测定肺系数,并进行组织学和免疫组织化学研究。通过蛋白质印迹分析测定了接触氟塑料热降解产物的老鼠肺组织中的水通道蛋白-5的含量。已确定,中毒于羰基氯和含全氟异丁烯的氟塑料的热降解产物的老鼠,接触后30分钟肺组织中水通道蛋白-5和上皮钠通道阳性细胞的相对含量增加。接触后60分钟,观察到中毒性肺水肿间质期迹象和肺系数增加。二氧化氮接触后30分钟,测定肺系数增加、水肿间质期的迹象明显和水通道蛋白-5阳性细胞的相对含量增加。使用抗水通道蛋白-5抗体进行蛋白质印迹分析时,发现分子量为25和50kDa的复合物染色强度增加,这可能证明水通道蛋白-5四聚体的形成,或许其是从细胞内转移至肺泡细胞质膜。由此可见,在因肺毒性物质接触测试而导致的中毒性肺水肿的发病机制中,水通道蛋白-5发挥着重要作用。对该通道的靶向作用可能是一种很有前景的中毒病理治疗方法。
