不同环境条件下红细胞的扫描电镜形态改变

Morphologic Changes of Red Blood Cells in Various Conditions Under Scanning Electron Microscope

为了探索红细胞在不同条件下的改变，作者用扫描电镜观察了水中和空气中经历６天的血凝块和保存不同时间的血纱布上红细胞的形态。发现在水中和空气中经历了６天的红血球形态保存较完整，红细胞直径为５４８～５８８μｍ。在保存长达１４年的血纱布上的红细胞明显变形，有的出现破碎，但在扫描电镜下可以识别红细胞膜的结构。作者对扫描电镜下的红细胞的形态和法医学意义进行了讨论。

To study the changes of RBC in various conditions,blood clots elapsed 6 days in water and air and bloodstains stored in variant time were observed under Scanning Electron Microscope (SEM).The results showed that the morphology of RBC elapsed 6 days in water and air seemed to retain their integrity.They were measured 5.48 5.88μm in diameter,whereas the RBC in the bloodstains stored 14 years were obviously disfigured and some appeared membrane cracking.However,the structure of RBC membrane was well recognized under the SEM.The morphological changes under the SEM and the forensic significance of the RBC were discussed.
