鸟类内耳毛细胞是否存在再生现象,如今已受到广泛的重视,国内亦初步开展了这方面的研究工作。石蜡切片技术是研究细胞形态和组织结构的常用方法,也是放射自显影、免疫组织化学、酶组织化学等研究方法的基础,由于鸟类耳蜗的解剖结构与豚鼠和人的耳蜗不尽相同,故鸟类耳蜗切片的制作存在着许多新的技术性问题。本文根据雏鸡耳蜗的解剖学特点,对雏鸡耳蜗采用取线定位包埋的方法制备石蜡切片,取得了较好的观察效果。报告如下, The regeneration of the inner ear hair cells of birds has now received widespread attention and the research work in this field has been carried out in China. Paraffin section technique is a common method to study cell morphology and tissue structure. It is also the basis of research methods such as autoradiography, immunohistochemistry and enzyme histochemistry. Since the anatomy of the bird’s cochlea is different from that of guinea pig and human cochlea, There are many new technical issues in the production of bird’s cochlear slices. According to the anatomical characteristics of the chick cochlea, paraffin sections of the chick cochlea were prepared by taking the line positioning and embedding, and the observation results were good. Report is as follows
