硝酸银染色法适用于显示一般染色法无法显示的微细表面组织结构,在内耳病理实验中有重要的实用价值。许多学者对耳蜗基底膜硝酸银浸润染色进行了铺片观察,但是用硝酸银溶液对全内耳终器进行染色,尚未见报道。我们采用全内耳膜迷路硝酸银灌流染色技术,对正常和内耳病变豚鼠的基底膜、血管纹、球囊斑、椭园囊斑以及三个壶腹嵴进行了铺片观察,得到较为满意结果。报道如下。 The silver nitrate staining method is suitable for showing the fine surface structure that can not be displayed by the general staining method and has important practical value in the pathological experiment of the inner ear. Many scholars have observed the infiltration of silver nitrate staining of cochlear basement membrane. However, it has not been reported that silver nitrate solution is used to stain the whole endoscope. We use all-internal eardrum lost silver nitrate perfusion staining technique to normal and inner ear lesions in guinea pig basement membrane, vascular pattern, balloon plaques, oval plaque and three ampulla ridges were observed, and the results were satisfactory. Reported as follows.
