초록

해양오염의 진단을 위한 생화학적 오염지표 설정의 기초 연구의 일환으로, 오염이 심각한 서해(또는 황해)산 넙치(Paralchthys olvaceus)의 노 및 근육중의 아세틸콜린에스테라아제(AChE) 및 무털릴콜린에스테라아제(butyrylcho-linesterase:BChE)의 활성, 그리고 전산탈수소효소(lactate dehydrogenase:LDH)의 활성을 분석${\cdot}$평가하였다. 서해안의 양식산의 넙치의 뇌 및 근육증의 AChE의 활성은 동해안의 포항의 자연산 넙치의 노 및 근육의 AChE의 활성 대비 각각 40-50% 미 40-55% 정도나 유의적으로 저하되었을 뿐만 아니라 서해안의 자연산 넙치의 뇌 및 근욱중의 AChE의 활성 대비 각각 15-40% 및 25-35% 정도나 유의적으로 저하되었다. 또 서해안의 양식산 넙치의 뇌 및 근육중의 BChE의 활성은 동해안 포항의 자연산 넙치의 뇌 및 근육중의 BChE의 활성 대비 각각 70-75% 및 65-75% 정도나 유의적으로 저하되었ㅇ르 뿐만아니라 서해안의 자연산 넙치의 뇌 및 근육중의 BChE의 활성 대비 각각 50-75% 및 45-50% 정도나 유의적으로 저하되었다. 한편 서해안의 양식산 넙치의 혈약중의 LDH의 활성은 동해안 포항의 자연산 넙치의 혈액중의 LDH의 활성 대비 10-50%정도나 유의적으로 증가하였을 뿐만 아니라 서해안의 자연산 넙치의 혈액중의 LDH의 활성 대비 20-25% 정도나 유의적으로 증가하였다. 따라서 서해안의 양식산 넙치의 오염 뿐만 아니라 자연산 넙치의 오염 가능성도 있다는 사실을 알 수 있다.

This study was designed as a part of efforts to investigate the biochemical pollutant markers for diagnosis of maine pollutions by changes in cholinesterase activity of the flounder (Paralichthys olivaceus)in Yellow Sea of Korea. Acetylcholinesterase (AChE) activities in brain and muscle of cultured flounders in Yellow Sea were remarkably lower (40-50% and 40-55%, respectively)than those of wild flounder in Pohang (control) of East Sea, but AChE activities in brain and muscle of wild flounders in Yellow Sea were significantly lower(15-40% and 25-35%, respectively)than those of wild flounder in Pohang of East Sea. Butyrylcholinesterase(BChE) activities in barin and muscle of cultured flounders in Yellow Sea were remarkably lower(70-75% and 65-75%, respectively) than those of wild flounder in Pohang of East Sea, but BChE activities in barin and muscle of wild flounders in Yellow Sea were significantly lower (15-40%and 25-35%, respectively)than those of wild flounder in Pohang of East Sea. Lactate dehydrogenase (LDH) activities in serum of cultured flounders in Yellow Sea were significantly 10-50% higher than those of wild flounder in Pohang of East Sea, but LDH activities in serum of wild flounders in Yellow Sea were significantly 20-25% higher than those of wild flounder in Pohang of East Sea. It suggests that AChE and BChE activities in brain and muscle of cultured and wild flounders of Yellow Sea may be used as the most effective mean in a biochemical markers for diagnosis of pollutant effects by organophosphorus pesticides.
