为了探索钨矿脱尘工人中晚发性矽肺(以下简称晚矽)的发病特点和规律,我们对849名男性钨矿脱尘者进行了14年的动态观察。现将结果报道如下。 对象和方法 (一)观察对象 1966—1967年期间,赣南几大钨矿的一批粉尘作业工人调往我地区某矿。我们选择其中符合下列条件者作为观察对象:(1)有完整的职业史和矽肺检查史;(2)脱尘后未再从事接尘作业;(3)脱尘后携有0或0—1期的X线胸片。
In order to explore the pathogenesis and regularity of late onset silicosis (hereinafter referred to as “late silicon”) in demineralized workers, we conducted a dynamic observation of 849 male tungsten mine dust removers for 14 years. The results are reported below. Subjects and Methods (I) Observations During 1966-1967, a group of dust mines in several major tungsten mines in southern Jiangxi were transferred to a mine in our area. We choose those who meet the following conditions as the object of observation: (1) have a complete history of occupational history and silicosis inspection; (2) after the dust was no longer engaged in dust operations; (3) after the dust carrying 0 or 0-1 Period of the X-ray.
