| 摘 要： | 【目的】研究红树蚬Polymesoda erosa与歪红树蚬Polymesoda expansa对短链氯化石蜡(Short-chain Chlorinated Paraffins,SCCPs)胁迫应答的差别。【方法】观察两种蚬血细胞的溶酶体中性红保持时间(Neutral Red Retention Time,NRRT)、总抗氧化活力(Total Antioxidant Capacity,T-AOC)、丙二醛(MDA)含量对不同剂量-时间SCCPs的响应。【结果】在低浓度SCCPs胁迫早期,两种蚬NRRT均表现出"毒物兴奋效应",其中红树蚬表现更为明显;T-AOC值、MDA含量表明歪红树蚬对于逆境的抵抗力更强。中、高浓度SCCPs胁迫下两种蚬对SCCPs响应结果相似。【结论】红树蚬与歪红树蚬对SCCPs胁迫应答随剂量-时间变化总体趋势相似。歪红树蚬对逆境的抵抗力略强。

| Abstract: | Objective]To study the different responses of SCCPs(short-chain chlorinated paraf-fins)stress between Polymesoda erosa and Polymesoda expans .Methods]The lysosome neu-tral red retention time(NRRT),total antioxidant capacity(T-AOC)and MDA content of blood of two clams were observed along with the change of the different time and dose SCCPs.Re-sults]In the early stage of low SCCPs concentration stress,the NRRT of two clams showed hormesis,especially for Polymesoda erosa .T-AOC and MDA content showed that Polymesoda expansa was more resistant to adversity.The responses of two clams to SCCPs were similar under middle and high concentrations of SCCPs stress. Conclusion ] The responses of Polymesoda erosa and Polymesoda expansa to SCCPs stress were similar with the change of dose and time,and the resistance of Polymesoda expansa to adversity was slightly stronger. |
