作者采用扫描电镜对二例生前无呼吸道系统疾病的成人鼻腔粘膜进行了全面积的序列性观察,得出了如下结果:1.自中鼻甲上缘以上的鼻粘膜表面无纤毛生长,均为光滑的上皮。这部分约占鼻腔总面积的1/3～1/4。2.自中鼻甲以下的鼻腔粘膜表面均有纤毛生长,约占鼻腔总面积的2/3～3/4。鼻阀区无纤毛生长。3.鼻腔内纤毛的长度和密度不一致,在鼻底和下鼻道的纤毛排列紧密,纤毛长度为6～7μ,看不到非纤毛细胞。下鼻甲及中鼻道的纤毛排列分散,被一些非纤毛细胞分隔,这些非纤毛细胞属分泌型细胞,如杯状细胞。纤毛细胞与非纤毛细咆的比例约为2∶1～1∶1,纤毛长度为4～5μ。中鼻甲及中鼻甲上缘表面的纤
The authors used scanning electron microscopy of two cases of nasal mucosa without nasal respiratory disease in patients with a comprehensive sequence of observations, the following results: 1. Nasal mucosa from the superior turbinate on the surface of the non-cilia growth, are smooth Of the epithelium. This part of the total area of the nasal cavity about 1/3 ~ 1 / 4.2. Since the nasal cavity below the nasal mucosal surface has ciliary growth, accounting for the total area of the nasal cavity 2/3 to 3/4. Nose valve area without ciliary growth. 3. The length and density of nasal cilia inconsistent in the nose and the bottom of the nose cilia arranged closely, cilia length of 6 ~ 7μ, can not see non-ciliated cells. The cilia of the inferior turbinate and middle nasal passages are scattered and separated by non-ciliated cells, which are secreted cells such as goblet cells. The ratio of ciliated cells to non-ciliated roes is about 2: 1 to 1: 1, and the length of cilia 4 to 5 μ. Middle turbinate and middle turbinate on the edge of the surface of the fiber
