동양달팽이 (Nesiohelix samarangae) 의 타액선 (salivary gland) 과 타액관 (salivary duct) 의 구조적 특징과 기능을 이해하기 위하여 조직화학적 및 미세구조적 연구를 수행하였다. 타액선에서는 미세구조 관찰에서 1유형의 상피세포 (epithelial cell) 와 1유형의 지지세포 (supporting cell), 그리고 6유형 (T1-T6) 의 선세포들이 관찰되었다. 6유형의 선세포들 중 4유형의 선세포들이 조직화학적 실험에서 관찰되었다. 그 중 T1 선세포의 분비과립들은 산성점액다당류로 확인되었고, T2, T3, T4 선세포들의 분비과립들은 중성점액다당류로 확인되었다. 타액관에서는 1 개 유형의 T9의 상피세포가 관찰되었다. T9 세포는 타액관을 구성하는 유일한 상피세포로서, 형태는 원주형이었으며 유리표면에는 microvilli가 존재하였다. 기저막 쪽의 원형질막은 심하게 주름져 있어 전반적으로 수지상 형태를 보여 주었다. 핵은 세포질 상부에 존재하였고 하부의 세장한 수지상 세포질 내에는 다수의 mitochondria를 내재하고 있었다.
Histochemical and ultrastructural studies on the salivary gland and salivary duct of a land snail Nesiohelix samarangae were conducted to observe structural characteristics and function.The salivary gland consisted of one type of epithelial cell, one type of supporting cell, and six types of gland cells.Four out of six gland cell types were histochemically identified on these secretions. The one secreted acid mucopolysaccharide and the other three secreted neutral mucopolysaccharide.The salivary duct epithelium had only one type of columnar cell with microvilli on its luminal surface. The basal protoplasmic membranes of the epithelial cells were deeply infolded so many times all along the cell bases.
