도룡뇽 (Hynobius leechi) 피부선의 미세구조: I. 점액선

The ultrastructures of the mucous glands in the Asiatic land salamander (Hynobius leechi) skin were observed by means of electron microscope. The results were as follows; 1. The mucous gland of the Asiatic land salamander skin consisted of a body of gland and a duct. The body of gland consisted of the glandular epithelial and the myoepithelial cells. 2. The light, the dark, the mitochondria-rich, the endoplasmic reticulum-developed, the secretory granule-containing and the vesiculated cells were observed in the mucous glandular epithelium. 3. It is supposed that the light, the dark and the mitochondria-rich cells are undifferentiated cells, the endoplasmic reticulum-developed cell is pre-secretory cell, the secretory granule-containing cell is mature cell and the vesiculated cell is evacuated cell.

도룡뇽 피부점액선의 미세구조를 전자현미경으로 관찰하여 다음과 같은 결과를 얻었다. 1. 피부점액선은 선체부와 분비관으로 구성되며, 선체부는 선상피세포와 근상피세포로 구성되었다. 2. 피부점액선의 선체부의 선상피세포는 명세포, 암세포, mitochondria-rich cell, endoplasmic reticulum-developed cell, secretory granule-containing cell 및 vesiculated cells들로 구성되었다. 3. 명세포, 암세포 및 mitochondria-rich cell은 미분화세포, endoplasmic reticulum-developed cell은 분비전기세포, secretory granule-containing cell은 성숙세포 그리고 vesiculated cell은 분비후기세포라고 생각된다.
