随着现代工業的发展,保护工人的健康,已经成为每个医务工作者的重要任务,下面將介绍一种生产过程中常见的职業病——硅肺。硅肺是由于長期吸入了含有一定濃度的二氧化硅粉塵的空气所引起的肺部病变。患者多为矿山和特种工厂的工人。以前人们曾把硅肺与肺结核混淆起来,当时在煤矿工人中发现有呼吸困难的现象就称为“煤工痨病”,直到1861年才知道它們是两种不同的疾病,1866年才正式証明硅肺是由于游离在空气中的二氧化硅所引起的疾患。当二氧化硅被吸入后,作为異物存在就会刺激肺組織而引起炎症反应及局部组織增生;此时硅末在細胞內逐漸溶解成硅酸,是有毒性刺激的,能使細胞受损,最后在肺內产生广泛的纖維性变即硅結节。硅肺的严重性多与 With the development of modern industry, protecting the health of workers has become an important task for every medical worker. Next, we will introduce a kind of silicosis that is common in the production process. Silicosis is caused by prolonged inhalation of airborne lungs containing a certain concentration of silica dust. Most of the patients are miners and workers in special factories. Silicosis was previously confused with pulmonary tuberculosis. At that time, the phenomenon of dyspnoea found among coal miners was called “coal gangrenous disease.” It was not until 1861 that they were known as two different diseases. It was only in 1866 that silicon The lungs are caused by the free silica in the air. When silica is inhaled, the presence of foreign body as a foreign body will stimulate the lung tissue and cause inflammatory reactions and local tissue proliferation; this time in the cell gradually dissolved silicon into silicic acid, is toxic to stimulate, can make the cell damage , Finally producing a wide range of fibrosis in the lungs that silicon nodules. The severity of silicosis and more
