탁도 변화가 붕어 조직의 항산화효소 활성에 미치는 영향

Abstract

- Present study aims to study antioxidant enzyme activity due to turbidity change invarious tissues of Carassius auratus. As for the changes of antioxidant enzyme activity in tissues ofC. auratuspursuant to the raising period under 50, 100, and 150 NTU with turbid water levels,there was no great difference between 50 NTU and 100 NTU compared to a control (0 NTU),When considering the antioxidant capacity in tissues of C. auratusin terms of DPPH free radicalscavenging activity, there was shown a high activity in gill and liver tissues, therefore, it is thoughtthat there appears a non-enzymatic antioxidant reaction when C. auratusis reared under thecondition of highly turbid water. As for the enzymatic antioxidant reaction of antioxidant enzymeactivities of superoxide dismutase (SOD), catalase (CAT), and glutathione-s-transperase (GST),increased in all tissues except for an integument, up to 20th day when it was started to be reared,and they showed a gradual decrease as time passed by. However, since the activity of glutathionereductase (GR) and glutathione peroxidase (GPX) is very low in almost all tissues, it is thoughtthat the role of those enzymes would be quite ignorable in the course of antioxidant process.
