PVC电缆燃烧烟雾吸入后临床发现阻塞型气道损害及肺间质增生性改变,结合动物实验所见,我们认为上述损害不像是由炎性及免疫效应细胞间接介导的肺泡炎所致,而更可能是刺激性烟雾对肺实质细胞和一些非细胞成份的直接毒作用结果。
PVC cable combustion smoke inhalation clinically found obstructive airway damage and pulmonary interstitial proliferative changes, combined with animal experiments, we believe that the damage is not caused by inflammatory and immune effector cells indirectly mediated by alveolitis, But more likely the direct toxic effect of irritating fumes on lung parenchymal cells and some non-cellular components.
