本文报道了14例肺锡尘沉着症工业卫生调查、动物实验、临床观察及部分病例随访17～22年X线检查结果。提出了鼓风炉烟雾为本病致病因子的论点,指出了本病与锡尘肺病理变化的差别:后者可致肺纤维性变及胶原化,本病则仅为锡尘沉积,或有轻微的细胞反应,但不致纤维性变。本病晚期X线所见有两个重要特征,即见于支气管的“铸型征”和见于气管并沿其周壁凝集弥散的“凝霜征”。
This paper reports the results of X-rays from 17 to 22 years of industrial health investigations, animal experiments, clinical observations, and follow-up of some cases of lung tin dust deposition. The argument of the blast furnace smoke as the pathogenic factor of the disease was put forward, and the difference between the pathological changes of this disease and that of tin dust pneumoconiosis was pointed out: The latter can cause lung fibrosis and collagenization, and the disease is only tin dust deposition, or there is slight The cells react but do not become fibrotic. The late X-ray seen in this disease has two important features, namely the “mold sign” seen in the bronchus and the “condensation cream sign” seen in the trachea and agglutinated along its peripheral wall.
