Abstract
研究了在实验生态条件下,不同浓度可溶性0#柴油的暴露对真鲷幼鱼内脏组织超氧化物歧化酶(SOd)和过氧化氢酶(CAT)活性的影响.实验结果表明:SOd酶活性对于油污染胁迫呈现出明显的剂量-诱导效应关系.在同一剂量溶度作用下,延长暴油时间,能诱导鱼体内SOd酶活性,抑制CAT酶活性.当污染胁迫解除后,其幼体内脏组织中的SOd酶和CAT酶活力均得到不同程度的恢复
 
The response of Superoxide Dismutase(SOD)and Catalase(Cat)in viscera tissues of Pagrosomus Major larvae to water soluble hydrocarbons in No.0 diesel oil was tested. Pagrosomus Major larvae were exposed to the solutions with the concentrations at 0.017, 1.22, 8.82 mg (No.0 diesel oil) /L for up to 15 days.Supernatants of viscera tissues were assayed for biochemical responses with oxidative stress SOD and Cat activities.The results showed statistically significant dose related increases in SOD activity on 9days.Compared to measurements on same dosed concentration exposure, significant increases of SOD activity in contrast to decreases of Cat activity were observed by prolonging time of expose.When releasing larvae from the highest dosed group to clear sea water levels for several days.The enzymes activities all returned towards corresponding control levels.
