我们在上级业务部门指导下,对703名铁路职工进行了铜蓝蛋白、粘蛋白、及血清蛋白电泳三项蛋白的均数测定对比,现初步小结如下: 调查对象及条件:对照组选择无砂尘作业史健康人89例,其中35例拍了胸片无显著变化。接触组为接触矽尘作业职工614例,全部拍胸片体检,由铁道部第二、五工程局矽肺诊断组及二局一处医院放射科会诊,按国家现行标准分别定为0期501例,0～Ⅰ期85例,Ⅰ、Ⅱ期19例(不合并结核,也未经任何治疗)。一、铜蓝蛋白变化 (一)方法及结果采用中国医学科学院卫生研究所介绍之“血清中铜蓝蛋白的测定方法——常量法”。利用铜蓝蛋白能氧化对苯二胺盐酸盐产生紫色反应,在波长
Under the guidance of the superior business department, we compared 703 railway workers with the average of the three proteins of ceruloplasmin, mucin, and serum protein electrophoresis. The preliminary summary is as follows: Subjects and conditions: The control group chose no sand 89 cases of dust operation history of health, including 35 cases of chest radiograph did not change significantly. Contact group for the work contact with silica dust 614 cases, all chest X-ray examination, by the Ministry of Railways two, five Engineering Bureau of silicosis diagnosis and two in a hospital radiology consultation, according to the current national standards were 0 501 cases , 85 cases in stage 0 ~ Ⅰ, 19 cases in stage Ⅰ and Ⅱ (without tuberculosis and without any treatment). First, changes in ceruloplasmin (a) methods and results using the Chinese Academy of Medical Sciences Institute of Health introduced “Determination of serum ceruloplasmin - constant method.” The use of ceruloplasmin can oxidize p-phenylenediamine hydrochloride to produce a violet color reaction at the wavelength
