本文报告了50例尸解煤矿工人肺组织生化成份及SiO_2含量(mg/g干肺)的分析结果。测定结果表明,矽肺和煤矽肺组总类脂与胆固醇含量均明显高于对照组(P<0.05),矽肺组磷脂亦有显著增高(p<0.01)。Ⅰ期煤工尘肺的总类脂、磷脂显著高于对照组(P<0.05),而Ⅱ期煤工尘肺的SiO_2含量显著增高(P<0.01),胶原亦有增高的趋势。当煤工并发肺癌或结核时,胆固醇明显增高(P<0.05)。 由此可见,肺组织化学成份的含量随煤工尘肺的不同类型和不同期别,以及有无合并症而有不同。
This paper reports the results of the analysis of lung biochemical composition and SiO 2 content (mg / g dry lung) in 50 cases of coal mines. The results showed that the total lipids and cholesterol levels in silicosis and coal silicosis groups were significantly higher than those in control group (P <0.05), phospholipids in silicosis group was also significantly increased (p <0.01). The total lipids and phospholipids of stage Ⅰ pneumoconiosis workers were significantly higher than those of the control group (P <0.05), while those of stage Ⅱ workers workers’ pneumoconiosis were significantly increased (P <0.01). Collagen also increased. When coal workers complicated by lung cancer or tuberculosis, cholesterol was significantly increased (P <0.05). Thus, the content of chemical composition of lung tissue with coal workers pneumoconiosis of different types and different periods, and whether there are complications and different.
