Abstract

The anatomy and histology of the olfactory organ in Oryzias sinensis was researched using a stereo microscope and light microscope. In the gross structure, the paired olfactory organs on the dorsal part of the head consist of two nostrils (a circular anterior nostril and a slit posterior nostril in a distance), a single olfactory chamber and a single accessory nasal sac. In the histological study, the epithelium of the olfactory chamber is classified into both sensory and non-sensory regions. The sensory epithelium consists of olfactory receptor neurons, supporting cells, basal cells and vesicles, and is islet in distributional pattern. The non-sensory epithelium is composed of stratified epithelial cells and two types of mucous cells (acidic and neutral cells). The epithelium of the accessory nasal sac has swollen stratified epithelial cells, mucous cells with a rich glycoprotein. Such an olfactory anatomy and histology of O. sinensis may reflect its habitat surrounding stagnant and polluted water.

한국산 대륙송사리 Oryzias sinensis의 후각기관을 실체현미경과 광학현미경을 이용하여 해부 및 조직 화학적 특징들을 조사하였다. 전체적 구조에서 후각기관은 두부의 주둥이 위에 한 쌍으로 존재하였으며 다소 떨어져있는 전비공과 후비공, 한 개의 비강, 한 개의 비낭으로 구성되었다. 비강내 상피는 감각상피와 비감각상피층으로 구분되었다. 감각상피는 후감각세포, 지지세포, 기저세포 그리고 공포들로 구성되었다. 비감각상피는 층상상피 세포, 산성과 중성 점액세포들로 구성되었다. 비낭의 상피층은 층상상피세포와 배상세포들로 구성되었다. 결과적으로 이러한 대륙송사리의 후각기관의 해부 및 조직화학적 특징들은 농경지에서의 정체되고 오염되어있는 수환경을 반영하는 것으로 사료된다.
