作者在以前的组织学研究中发现很多婴儿颞骨(TB)都表现出急性中耳炎(AOM)和分泌性中耳炎(SOM)的特性,但大多数TB_s标本中两者的组织学特性分界不清。本文通过对30个婴儿TB_s的组织学研究,阐明了AOM和SOM与正常中耳粘膜的组织学特性。作者随机抽取30只新生儿至2岁婴儿的颞骨标本,连续切片,HE及PAS染色,光镜观察,对炎性细胞和粘液成分加以鉴定及半定量研究,发现30只耳均有炎性浸润改变,将TB_s分为二组:①新生儿组(出生至一月)及②婴儿组(3～24月),每个TB_s取6张切片,分别代表中耳的前、中、后三部分。结果发现30
In previous histological studies, the authors found that many infratentorial temporal bones (TBs) exhibit characteristics of acute otitis media (AOM) and otitis media with effusion (SOM), but histological features are indistinguishable in most TB_s specimens. In this paper, histological studies of TB_s in 30 infants revealed the histological characteristics of AOM and SOM and normal middle ear mucosa. The authors randomly selected temporal bone specimens from 30 neonates to 2-year-old infants. Serial sections, HE and PAS staining, light microscopy, inflammatory cell and mucus components were identified and semi-quantitative study and found that 30 ears were inflammatory infiltration TB_s were divided into two groups: ① neonatal group (born to January) and ② infant group (3 to 24 months), each taking 6 slices of TB_s, representing the middle ear before, during and after the three parts . The results found 30
