摘要: 应用扫描电镜对大鼠溺死后不同时间气管纤毛病理变化进行了观察,发现溺死大鼠气管纤毛局部紊乱,杯状细胞顶端开口增多,纤毛表面粘附有较多的絮网状结构.随死后时间延长,纤毛出现粘结、倒伏、结构破坏、消失等死后变化.结果表明,用扫描电镜观察上述变化有助于溺死死因诊断和死后经过时间的推断.

Abstract: The changes of tracheal cilia of drowning rat were observed by SEM at 0,24,48,72,96h after death.The authors found:the tracheal cilia lost their normal arrangement in some area,and the opening increased on the top of the Goblet cell.There were some thing resembling cotton,or looking like network on the surface of tracheal cilia.At different times after death,the tracheal cilia appeared adhering,downing,and destroying,Goblet cell membrane creasing,the top of cell flattening and the cell collapsing.Observing this changes,we could estimate the time of death.

Key words: drowning, time, tracheal cilia
