초록

광 자극에 대한 향어, Cyprinus carpio [Linnaeus]의 심전도를 규명하기 위하여, 어체내에 전극을 삽입하여 3가지 광 자극 (10,100,400 lux)에 대하여 심전도를 주간과 야간으로 구분하여 60분간 연속적으로 조사한 심전도를 현황별로 분석한 심전수와 생체전위는 다음과 같다. 1. 향어는 마취후 5분 뒤에 안정상태에 도달하였고, 안정상태에서 평균심전수는 주간에 64.9 beat/min, 야간에 65.3 beat/min였고, 평균생체전위는 주간에 36.9 nV, 야간에 32.9nV로 나타났다. 2. 자극별 평균 심박수는 1) 자극상태에서, 10 lux인 경우 주간에 68.7 beat/min, 야간에 46.0 beat/min였고, 100 lux인 경우 주간에 53.4 beat/min, 야간에 44.1 beat/min였으며, 400 lux인 경우 주간에 53.2 beat/min, 야간에 40.1 beat/min로 나타났고, 2) 회복상태에서, 10 lux인 경우 주간에 67.9 beat/min, 야간에 57.2 beat/min였고, 100 lux인 경우 주간에 68.8 beat/min, 야간에 61.0 beat/min였으며, 400 lux인 경우 주간에 69.6 beat/min, 야간에 63.6 beat/min로 나타났다. 3. 자극별 평균생체전위는 1) 자극상태에서, 10lux인 경우 주간에 59.1 nV, 야간에 24.0 nV였고, 100 lux인 경우 주간에 26.8 nV, 야간에 45.6 nV였으며, 400 lux인 경우 주간에 71.7 nV, 야간에 14.4 nV로 나타났고, 2) 회복상태에서, 10 lux인 경우 주간에 38.8 nV, 야간에 27.3 nV였고, 100 lux인 경우 주간에 29.0 nV, 야간에 39.3 nV였으며, 400 lux인 경우 주간에 66.1 nV, 야간에 21.4 nV로 나타났다.

The authors examined the response of electrocardiogram (ECG) of Mirror carp, Cyprinus carpio [Linnaeus] to light stimuli. The experiments were performed in such a way that three levels of light stimuli (10, 100, and 400 lux) were given to fishes with an electrode inserted into their bodies and then their ECGs were recorded continuously for 60 minutes. The results which are divided into by day and by night and then analyzed by fishes conditions are as follows : 1. Mirror carps reached a stable condition 5 minutes after anesthesia. In this condition, the average heart rate was 64.9 beat/min by day and 65.3 beat/min by night. And the average action potential was 36.9 nV by day and 32.9 nV by night. 2. The average heart rate by three levels of light stimuli was, 1) In a stimulus condition, in case of 10 lux 68.7 beat/min by day and 46.0 beat/min by night, in case of 100 lux 53.4 beat/min by day and 44.1 beat/min by night, and in case of 400 lux 53.2 beat/min by day and 40.1 beat/min by night. 2) In a recovery condition, in case of 10 lux 67.9 beat/min by day and 57.2 beat/min by night, in case of 100 lux 68.8 beat/min by day and 61.0 beat/min by night, and in case of 400 lux 69.6 beat/min by day and 63.6 beat/min by night. 3. The average action potential by three levels of light stimuli was, 1) In a stimulus condition, in case of 10 lux 59.1 nV by day and 24.0 nV by night, in case of 100 lux 26.8 nV by day and 45.6 nV by night, and in case of 400 lux 71.7 nV by day and 14.4 nV by night. 2) In a recovery condition, in case of 10 lux 38.8 nV by day and 27.3 nV by night, in case of 100 lux 29.0 nV by day and 39.3 nV by night, and in case of 400 lux 66.4 nV by day and 21.4 nV by night.
