摘　　要：以金鱼 (Carassiusauratus)体内超氧化物歧化酶 (Superoxide dismutase,SOD)活力、乙酰胆碱酯酶 (Acetylcholinesterase,ACh E)活力变化为指标 ,观察了枝管藻多糖对久效磷暴露的水体中鱼类生理功能的影响。结果表明 :用枝管藻多糖灌胃鲫鱼 1 5d,枝管藻多糖能显著降低久效磷对鱼类体内 SOD活力的诱导和有效阻止久效磷对鱼类中枢神经系统 ACh E活性的抑制 ,具有拮抗久效磷农药对鱼类毒害的作用。The effects of polysaccharide from Cladosiphon okamuranus (CP) on the physiological function of fish after exposure to monocrotophos were studied by the changes of the activities of superoxide dismutase (SOD) and acetylcholinesterase (AChE) in crucian. The results showed that SOD activity induced by monocrotophos was reduced significantly and AChE activity depressed by monocrotophos was increased obviously after being given CP for 15d. The study suggests that CP can protect fish from the harmful effects of monocrotophos.
