至今所有研究中耳渗液的方法还不能把其中的细胞成份与粘液分离开来。以前采用直接涂片法,当粘液变稠成索带时施加给细胞的力可使之变形,因而对细胞类型的正确估价和解释常遇到困难。作者介绍一种新方法有助于解决这一问题。在10名3～8岁的患儿中取得15份中耳渗液标本。用结核菌素注射器接上无菌导管,经鼓膜 So far, none of the methods for studying middle ear effusion have separated the cellular components from mucus. In the past, the direct smear method, which deforms the mucus when applied to the cells as the strands become thick, often presents difficulties in correctly evaluating and interpreting cell types. The authors introduce a new approach that helps to solve this problem. Fifteen specimens of middle ear effusion were obtained from 10 children aged 3 to 8 years old.
