本文采用大鼠现场自然吸入茶尘作动物实验性尘肺观察,发现染尘后肺干重、胶原蛋白、肺气肿程度和血清铜蓝蛋白含量等指标,随染尘时间及剂量的增加而上升,X线见肺纹理增粗、增多、模糊或呈斑片状浸润灶。实验结果证明了茶尘对肺组织的病理损害。
In this paper, we used the natural inhalation of tea dust in rats as experimental pneumoconiosis and found that the indexes of lung dry weight, collagen, emphysema and ceruloplasmin were increased with the increase of dust time and dose X-ray, see lung thickening, increased, blurred or patchy infiltration stove. The experimental results prove the pathological damage of tea dust to lung tissue.
