该实验目的是研究酸(pH=5,Al=0μg/L)、铝(pH=7,Al=800μg/L)单独及联合(pH=5,Al=800μg/L)作用下,锦鲤鱼脑、肾、肝超氧化物歧化酶(SOD)活性的反应变化情况。结果表明,与对照组(pH=7,Al=0μg/L)相比,锦鲤鱼脑无论在酸、铝单独作用还是联合作用下,SOD活性在染毒第1天均显著降低(p<0.01),但随后酸铝联合组、单独作用组分别在3 d、9 d恢复正常;肾SOD则只有在酸铝联合作用下,且只有在染毒第1天产生显著抑制(p<0.01),随后也恢复正常;肝SOD则无论在何种情况下,均无抑制现象发生。
The purpose of this experiment was to study the effects of different concentrations of Al (pH = 7, Al = 800μg / L) , Kidney, liver and superoxide dismutase (SOD) activity changes. The results showed that compared with the control group (pH = 7, Al = 0μg / L), the SOD activity of Koi fish brain decreased significantly (P <0.01) on the first day after exposure to either acid or aluminum alone or in combination ), But then the combination of acid and aluminum, the role of the group were returned to normal in 3 d, 9 d, respectively; renal SOD only in the combination of acid and aluminum, and only in the first day of exposure produced significant inhibition (p <0.01) Then returned to normal; liver SOD no matter under what circumstances, no inhibition occurred.
