| 摘 要： | 目的介绍连续变倍体视显微镜(Zoom-stereo microscope)的一种特殊的暗视野照明方法在内耳显微解剖中的应用。方法在小鼠耳蜗解剖中,采用纤维导光束(也称万向冷光源)从玻璃平皿侧面照射(侧射式),使光线从侧面进入,经标本反射后进入连续变倍体视显微镜光学系统而成像;并与常规的两种照明方法(落射式和透射式)的效果进行比较。结果侧射式照明效果明显比落射式和透射式好,其背景光线的干扰显著降低,达到暗视野成像效果。结论采用侧射式照明,可以提高内耳显微解剖技术的水平。

| Abstract: | Objective To introduce a special method of illumination for the microdissection of the mice inner ear using the zoom-stereo microscope.Methods Using the fibre optic illuminatior,this would allow the light to enter from the lateral of the flat plate,and the reflect light from the specimen would enter into the optic system of the zoom-stereo microscope.Thus the lateral illumination was compared with the traditionary illuminations,namely,the falling-illumination and the transillumination.Results The effect of the lateral illumination was better than the traditionary illuminations with less background interference.Conclusion The lateral illumination can improve the microdissection of the inner ear. |
