우리나라의 주요 해산양식어종인 돌돔, Oplegnathus fasciatus을 대상으로 30, 60, 120 및 240 mg/kg의 아연을 40일 동안 경구 투여에 따른 아가미와 간의 항산화효소 활성의 변화를 검토하였다. 돌돔 간의 superoxide dismutase(SOD) 활성은 30~240 mg/kg 아연농도, glutathione peroxidase (GPx) 활성은 30~120 mg/kg의 아연농도에서 유의적으로 증가하였다. 돌돔 아가미의 SOD 및 Glutathione(GSH) 활성은 120 및 240 mg/kg 아연농도, GPx활성은 60~240 mg/kg의 아연농도에서 유의한 증가가 관찰되었다.
The objective of this study was to investigate the antioxidant enzyme (superoxide dismutase, SOD; glutathione, GSH; glutathione peroxidase, GPx) activities in liver and gill of rock bream, Oplegnathus fasciatus fed the experimental diets for 40 days. The experimental diets were prepared by adding with 30, 60 120 and 240 mg/kg to a commercial diet. In the liver, there were significant increases in SOD at 30~240 mg/kg. GPx activities of liver also were significantly increased at 30~120 mg/kg. The increased activities of SOD and GSH in the gills were observed in the 120 and 240 mg/kg, hence, GPx activity of gill exposed to lower concentrations of zinc (60~240 mg/kg) showed significant augmentation.
