생쥐 鼻中隔 各種 粘膜上皮 및 粘膜下腺의 分布樣狀과 그 表面積에 관한 硏究 = A Study for the Distribution Pattern and Surface Area of the Mucosal Epithelia and Gland in the Mice Nasal Septum

다국어 초록 (Multilingual Abstract)

In order to set the distribution pattern and surface area of the mucosal epithelium and submucosal gland in the mice nasal septum. 3-month-old healthy 6 mice weighing 25gm approximately have been contributed for this research.
For the mapping of the each nasal epithelium and submucosal gland in the submicroscopic level, the routine paraffin block of the mice nasal septum were cut as the 10㎛ thick at 110㎛ intervals. Consecutive 2 slides were stained with H-E and PAS and reconstructed in form of maps representing the structure in a sagittal plane.
The results obtained from this research were summarized as follows.
1. The unilateral nasal surface epithelial area of the mice nasal cavity was 31.23㎟
2. The areas of the stratified squamous epithelium, respiratory epithelium and olfactory epithelium which compose the unilateral nasal epithelium were 4.47㎟(14.3%), 12.7㎟(40.8%), and 14.02㎟(44.9%), respectively.
3. Submucosal glands in the mice nasal septum were divided into the PAS-positive, PAS-negative and Bowman's glands by the PAS staining.
4. The surface area of the PAS-positive glands in the nasal unilateral septum was 5.23㎟ which is located in the central area of the respiratory portion.
5. The surface area of the PAS-negative glands in the nasal unilateral septum was 5.05㎟ which is located above and below the PAS-positive gland.
6. The surface area of the Bowman's glands was 12.1 ㎟ which was located in the olfactory region.
7. In the vestibular region., 3 ducts of PAS-negative glands of the respiratory region are found, and below the nasal septum there is the infraseptal gland(PAS-negative).
