In the control groups at hour 6 there were congestion and hydroncus in alveoli pulmonis mesenchyma, aggregation and infiltration of neutrophil. 对照组6h肺泡间质淤血、水肿,嗜中性粒细胞聚集和浸润;
Results: 1. In the lung tissue of the model group 'rats after poisoned 14 days, HE dyeing patho-observation can see that lung tissue occurrence bulk fibroblast paraplasm displace alveolar space, alveoli pulmonis nearly disappearance, incrassate alveolar septum inter-desis pellet. 结果:1、模型组大鼠中毒14天时肺组织HE染色病理观察可见肺组织出现大量成纤维细胞异常增生取代肺泡腔,肺泡几乎消失,增厚的肺泡间隔相互融合成片。
