本实验将５０ｍｇ和１００ｍｇ沸石粉尘分别进行大鼠气管内染尘。分别于染尘后３、６、１２、１８个月分批处死，进行肺脏及肺淋巴结的病理学形态观察及肺胶原含量测定。结果表明，沸石粉尘具有致肺纤维化作用，但较石英尘的致肺纤维化作用为弱。
The experiment will be 50mg and 100mg zeolite dust were tracheal endotoxin in rats. The rats were sacrificed at 3, 6, 12, and 18 months after dying respectively. Pathological observation of pulmonary and pulmonary lymph nodes and determination of lung collagen content were performed. The results showed that the zeolite dust has the effect of inducing pulmonary fibrosis, but it is weaker than the pulmonary fibrosis caused by quartz dust.
