본 연구는 염화니켈 급성노출에 따른 북방전복의 산화스트레스효소 활성에 대한 변화를 알아보고자 하였다. 실험은 1개의 대조구와 5개의 농도구 (5.9, 8.8, 13.3, 20.0, 30.0 mg/L)에서 4일간 진행되었다. superoxide dismutase (SOD) 활성은 발과 간췌장의 경우 모든 니켈 노출구에서 증가하였으나 아가미에서는 감소하는 결과를 보였다. catalase (CAT) 활성은 발의 경우 20.0 mg/L 와 30.0 mg/L 니켈 노출구를 제외하고 증가하였으나 아가미에서는 대조구와 유사한 결과를 보였다. 간췌장에서는 모든 니켈 노출구에서 대조구에 비해 증가하는 결과를 보였다. 하지만 SOD와 CAT 활성 모두 대조구에 비해 유의적인 차이는 보이지 않았다 (P > 0.05).
This study was conducted to investigate the effects of nickel chloride (NiCl2) exposure on oxidative stress of the abalone Haliotis discus hannai. Experimental groups were composed of one control condition and five nickel chloride exposure conditions (5.9, 8.8, 13.3, 20.0, 30.0 mg/L). Superoxide dismutase (SOD) activity was increased in the foot and hepatopancreas, but decreased in the gill. Catalase (CAT) activity was increased in all exposure groups except 20.0 mg/L and 30.0 mg/L. In the gill, CAT activity was similar to the control group for all exposure groups. In the hepatopancreas, CAT activity was increased compared with the control group. However SOD and CAT activity showed not significant differences (P > 0.05).
