Abstract
为探讨As(Ⅲ)对紫贻贝(Mytilus galloprovincialis)肝胰腺和鳃组织抗氧化能力的影响,测定了1、10、100 μg/LAs (Ⅲ)暴露30天后,肝胰腺和鳃组织超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽巯基转移酶(GST)的活性变化以及谷胱甘肽(GSH)和丙二醛(MDA)含量的变化.结果发现:As(Ⅲ)暴露对紫贻贝肝胰腺CAT、SOD、GST活性以及GSH含量无显著影响,高浓度As(Ⅲ)暴露可诱导MDA含量的显著升高;对鳃组织而言,中等剂量暴露组CAT活性以及GSH含量较对照组水平极显著升高,高剂量As(Ⅲ)暴露组MDA含量较对照组也显著升高 研究结果表明,低浓度As(Ⅲ)长期暴露即可导致紫贻贝产生氧化胁迫,导致肝胰腺和鳃组织的脂质过氧化,且As(Ⅲ)对紫贻贝鳃组织的影响较肝胰腺组织更加显
