尘肺病人血液的组成和功能的改变与所能吸入的粉尘中二氧化硅的含量有关。本文选择了49例没有上呼吸道、肝、肾、消化道并发症的尘肺患者,90％年龄在40—50岁。 根据游离二氧化硅的含量,将病人分为两组:第一组煤尘肺病人23例,SiO_2含量为2—4.5％,第二组Ⅰ—Ⅱ期矽肺病人26例,SiO_2含量为60％或以上,对照组是没有接触过生产性毒物的20名健康人。
Changes in the composition and function of blood in patients with pneumoconiosis are related to the amount of silica contained in the dust that can be inhaled. In this paper, 49 cases of pneumoconiosis without upper respiratory tract, liver, kidney and gastrointestinal complications were selected, and 90% were aged 40-50 years old. According to the content of free silica, the patients were divided into two groups: the first group of patients with pneumoconiosis 23 cases, SiO 2 content of 2-4.5%, the second group Ⅰ-Ⅱ stage silicosis in 26 cases, SiO 2 content of 60% or In the above, the control group was 20 healthy people who had no contact with productive poisons.
