Abstract:
10 adult female rats were used to study blast injuries of the air-way and lung. The conclusions are as follows. 1. There was significant difference in arterial blood gas analysis between the normal control and injury group. 2. The une-venness in the lung damage, bleeding, tear of the alveolar septa induced by the air shock wave was predominant, by scanning electron microscopy (SEM) as well as by the light microscopy (LM) . The bleeding may be due to the capillary rupture of alveolar septa. The' rope-like' structures seen might represent the fibre component in the septa which had more resistance to the local force and remained after the other components were wiped away by explosion. 3. Striping and fissure of the epithelium of trachea and bronchi of the injured group were detected. 4. The pathological changes observed with SEM were compared to those with LM.
