Physiologial-Biochemistrial Effects of Scylla paramamosain to Cu2+ or Zn2+ or Interaction of Cu2+ and Zn2+ Stress

Abstract

运用酶学分析方法和组织学技术,研究了水体中不同浓度Cu2+或Zn2+及Cu2+与Zn2+交互作用胁迫对拟穴青蟹生理生化以及鳃和肝胰腺显微结构的影响,探讨Cu2+或Zn2+及Cu2+与Zn2+交互作用胁迫对拟穴青蟹生理生化的影响及免疫防御机制,以期为其健康养殖水质管理提供理论指导,并为甲壳动物环境免疫学研究积累基础资料。本试验的主要结果和结论如下:1.Cu2+及Cu2+与Zn2+交互作用胁迫对拟穴青蟹血淋巴中THC的影响在Cu2+≤0.1mg·L-1胁迫第1天可诱导拟穴青蟹血淋巴中THC的升高,随着胁迫时间的延长,THC显著下降后回升至对照组水平,在Cu2+≥2.0mg·L-1及Cu2+与Zn2...The effects of Cu2+ or Zn2+ or interaction of Cu2+ and Zn2+ stress on the physiologial-biochemistrial parameters (THC、PO、SOD、GSH-Px、MDA、ACP 、AKP、Ua、UL) and histological structure of gill and hepatopancreas of mud crab Scylla paramamosain were determined by enzyme analysis and histology technique during 9d experimental time. The aim was to clarify the physiologial-biochemistrial effects and mechani...学位:理学硕士院系专业:海洋与环境学院海洋学系_海洋生物学学号:2005130217
