초록

목적: 한국관박쥐의 망막에서 원뿔세포의 middle/long(ML) opsin cone photoreceptors의 분포를 분석하여 박쥐의 시각계를 이해하고자 하였다. 방법: 표준면역세포화학법을 이용하여 성체 한국관박쥐의 망막을 대상으로 조사하였다. 결과: 4 개체의 망막 전체에서 추정된 ML opsin은 $27,336{\pm}2,130$개였으며, 평균밀도는 $7,854{\pm}268cells/mm^2$이었다. S opsin은 외핵층에 위치한 세포외절에서 일부 면역반응성을 보였다. 결론: ML opsin의 조직화된 분포와 S opsin의 발현 결과는 한국관박쥐가 밝은 빛에도 반응하며 색을 구별할 수 있는 기능을 가지고 있다는 것을 알 수 있다.

Purpose: This study was done to understand the visual system of bat by analyzing the distribution of middle/long (ML) opsin cone photoreceptors in the retina of the greater horseshoe bat. Methods: Experiments have been performed by standard immunocytochemical techniques on retina of the greater horseshoe bat Rhinolophus ferrumequinum. Results: The estimated numbers of ML cones were $27,336{\pm}2,130$ cells and the mean density of them was $7,854{\pm}268cells/mm^2$ among the four retinas. S opsin was appeared a little immunoreactivity in the outer segments of outer nuclear layer of cones. Conclusions: From the well organized spatial distributions of ML opsin and the immunoreactivity of S opsin in the retinas, the greater horseshoe bats have the functions not only reacting in the photopic vision but being able to distinguish the colors.
