在实验生态条件下 ,研究了不同浓度 0 #柴油的水溶性成分 (watersolublefraction ,WSF)对真鲷幼体内脏组织抗氧化酶活性变化的影响 .结果表明 :不同浓度的WSF污染对抗氧化酶活性变化的影响表现为抛物线型剂量 效应作用形式 ;同一剂量组随着污染时间的延长 ,过氧化物歧化酶 (SOD)活力上升 ,硒谷胱甘肽过氧化物酶 (Se GPx)和过氧化氢酶 (Ca)的活力下降 ;受污染幼体在污染解除之后 ,其抗氧化酶活性得到不同程度的恢复 .Response of antioxidase (superoxide dismutase, SOD; catalase, Ca; sedium\|dependent glutathione peroxidase, Se\|Gpx) in viscera tissues of Pagrosomus Major larvae to water\|soluble fraction in No. 0 diesel oil were tested. Pagrosomus Majoe larvae were exposed to the solutions with the conc. at 0.017, 1.22, 8.82?mg(No.0 diesel oil)/L for 15 days. The results showed that the activity of antioxidase was statistically significant dose\|related effect in different WSF concentrations. Under same dosed\|concentration exposure, significant increases in SOD activity and decreases of Ca and Se\|Gpx activity were observed with the prolonged exposure time. The activity of antioxidase returned to corresponding control level after the recovery experiment.
