摘要: 研究重金属锑胁迫下,分析生物体内各类酶活性的变化,了解生物对锑胁迫的响应机制。以斑马鱼为受体研究对象,探究不同浓度锑溶液(0、10、20、30和40 mg/L)和不同时间(24、48、96和144 h)培养下,斑马鱼体内不同酶活性的变化情况。研究结果表明,培养24 h时,不同浓度锑对斑马鱼体内除碱性磷酸酶以外的7种酶活性均有明显的抑制作用。随着锑胁迫时间增加,斑马鱼体内三磷酸腺苷酶、过氧化氢酶活性呈现先降低后增加的变化趋势;过氧化物酶、超氧化物歧化酶、乙酰胆碱酯酶、乳酸脱氢酶和酸性磷酸酶活性呈现“锯齿形”变化趋势;碱性磷酸酶酶活性呈现先增加后降低的变化趋势。综上分析表明锑对斑马鱼体内自由基调节、兴奋传导、能量代谢、物质运输、机体生长和免疫防御等生命过程都有明显的影响。

Abstract: We aim to study the changes of various enzymes’ activities in organisms under heavy metal antimony stress and to identify the response mechanism of organisms to antimony stress. The changes of different enzyme activities in zebrafish were explored at different concentrations of antimony solution(0,10,20,30,and 40 mg/L)and period(24,48,96,and 144 h). The results showed that the concentration of alkaline phosphatase in zebrafish was not dependent on the concentration of antimony,while the other 7 enzymes were significantly inhibited. With the increase of antimony stressing time,the activities of adenosine triphosphate and catalase in zebrafish presented a trend of first decreasing and then increasing;the activities of peroxidase,superoxide dismutase,acetylcholinesterase,lactate dehydrogenase,and acid phosphatase showed a “zigzag” trend;while the activities of alkaline phosphatase showed a trend of first increasing and then decreasing. In conclusion,antimony significantly affects the free radical regulation,excitation conduction,energy metabolism,substance transport,body growth and immune defense in zebrafish.
