Abstract

The olfactory organ of a Korean endemic species, Pseudobagrus koreanus, was investigated to describe its morphology and histology and analyze correlation between habitat environment and its ecological habits and characters, using a stereo microscope, a light microscope, and a scanning electron microscope. Its external morphology showed tubular anterior nostril at the tip of the snout and slit posterior nostril at the base of the nasal barbel. The olfactory chamber showed the rosette structure consisting of numerous lamellae radial and parallel to the medium raphe. The olfactory lamella has the sensory epithelium with olfactory receptor nuerons, supporting cells, basal cells, lymphatic cells, plasma cells and the non-sensory epithelium with stratified epithelial cells, mucous cells, lymphatic cells. In particular, 1) 41~43 (n=20) lamellae, 2) lymphatic cells and plasma cells, 3) mucous cells including neutral polysaccharid may be olfactory characteristics relevant to a stagnant or a standing habitat environment, nocturnal habit dependent on olfaction, and taxonomic characters compared at least to other catfish species.

한국 고유종 눈동자개 Pseudobagrus koreanus 후각기관과 서식처 환경, 생태적 습성의 연관성, 유연종들과의 특징 비교를 위해 실체현미경, 광학현미경, 주사전자현미경하에서 형태 및 조직학적 실험을 진행하였다. 후각기관의 외부 형태는 주둥이 끝에 위치한 튜브형의 전비공과 비수염(nasal barbel) 뒤쪽 기부에 위치한 틈새형(slit)의 후비공으로 구성된다. 내부의 비강에는 비선(raphe)을 중심으로 방사형 또는 서로 평행하게 배열된 많은 수의 후판으로 구성된 로제트 구조를 나타낸다. 후판에는 후감각뉴런, 지지세포, 기저세포와 림프구, 형질세포로 구성된 감각상피와 층상상피세포, 점액세포, 림프구로 구성된 비감각상피가 확인되었다. 그중 1) 41~43 (n=20)의 후판, 2) 림프구, 형질세포, 3) 중성 다당류 점액을 보유한 점액세포는 다소 정체된 유속의 서식처 환경, 후각 의존적인 야생성의 생태적 습성, 다른 유연 메기목 어류들과 비교되는 분류학적 특징으로 사료된다.
