检查了十七名电弧焊工人肺脏的组织学。这些人分别死于非肺部疾病(6例),呼吸衰竭(2例),肺部新生物或胸膜新生物。组织学所见最显著的特征是:有碳——铁末沉着症,周围小动脉的,细支气管周围淋巴细胞或浆细胞浸润,各种程度的间质纤维化和弥散,因刺激而引起的肺泡炎或形成上皮,支气管炎和细支气管炎。据认为电弧焊工的肺部疾患已不再是单纯的铁末沉着病了。据现在所知,焊烟
Seventeen arc welders examined the lung histology. These individuals died of non-pulmonary disease (6 cases), respiratory failure (2 cases), pulmonary neoplasms or pleural neoplasms, respectively. Histological findings of the most significant features are: carbon-iron fever, peripheral arterioles, peribronchial lymphocytes or plasma cells infiltration, various degrees of interstitial fibrosis and dispersion, due to stimulation caused Alveolitis or formation of epithelium, bronchitis and bronchiolitis. It is believed that the lung disease of arc welders is no longer a simple ferritinosis. As far as we know, welding smoke
