The distribution of the various epithelial types lining the nasal cavity in normal 7 and 16 weeks old male Fischer-344 rats and male B6C3F1 mice has been mapped at the light microscopic level. Photographs of transverse sections of the nose were analysed using a Zeiss Videoplan computerized image analysis system programmed for measurement and evaluation of count, area, perimeter and length. In rats, the volumes of the nasal cavity at 7 and 16 weeks are 156 and 257 mm3 respectively; while in mice the nasal cavity volume is essentially the same (32 . 5 and 31 . 5 mm3) at the same two ages. Total surface areas of the nasal cavity in rats at 7 and 16 weeks are 799 and 1344 mm2 respectively; and in mice 278 and 289 mm2. The percentages of the nasal cavity surface lined by squamous, respiratory and olfactory epithelium are similar at both ages in both species. Applications and significance of these data are discussed.
在光学显微镜水平绘制了正常7周龄和16周龄雄性Fischer-344大鼠及雄性B6C3F1小鼠鼻腔内衬的各种上皮类型的分布图。使用蔡司Videoplan计算机图像分析系统对鼻部横切面照片进行分析,该系统已编程用于计数、面积、周长和长度的测量与评估。在大鼠中,7周龄和16周龄时鼻腔体积分别为156和257立方毫米;而在小鼠中,相同两个年龄时鼻腔体积基本相同(32.5和31.5立方毫米)。7周龄和16周龄大鼠鼻腔的总表面积分别为799和1344平方毫米;小鼠为278和289平方毫米。在两个物种的两个年龄阶段,鼻腔表面由鳞状上皮、呼吸上皮和嗅觉上皮覆盖的百分比相似。讨论了这些数据的应用及意义。
