Abstract
The activity of the antioxidant defences catalase (CAT, EC 1.11.1.6), glutathione peroxidase (t-GPX, EC 1.11.1.9), glutathione reductase (GR, EC 1.6.4.2), phase II glutathione S-transferase (GST, EC 2.5.1.18) along with the NADPH-dependent cytochrome c (CYP) reductase (EC 1.6.2.4), NADH-dependent cytochrome c reductase (EC 1.6.2.2), and NADH-dependent ferricyanide (b5) reductase (EC 1.18.1.1) was determined in the digestive gland of mussels Mytilus galloprovincialis fed with Tetraselmis sp. pre-exposed to the water accommodated fraction of the Prestige oil. Mussel gills were also used for measuring acetylcholinesterase activity (AChE, EC 3.1.1.7) and lipid peroxidation (LP) as an indication of neurotoxicity and oxidative stress damage respectively. Bioaccumulation of the selected polycyclic aromatic hydrocarbons (2 to 6 rings PAHs) in mussels after 2, 4, 7 and 10 days of exposure did not show any significant trend; the 2-3 ring PAHs were best represented (51%). A significant (p
本研究测定了紫贻贝（*Mytilus galloprovincialis*）消化腺中抗氧化防御酶系统的活性，包括过氧化氢酶（CAT, EC 1.11.1.6）、总谷胱甘肽过氧化物酶（t-GPX, EC 1.11.1.9）、谷胱甘肽还原酶（GR, EC 1.6.4.2）、II相解毒酶谷胱甘肽S-转移酶（GST, EC 2.5.1.18），以及NADPH依赖型细胞色素c（CYP）还原酶（EC 1.6.2.4）、NADH依赖型细胞色素c还原酶（EC 1.6.2.2）和NADH依赖型铁氰化物（b5）还原酶（EC 1.18.1.1）；实验所用贻贝投喂了预先暴露于“威望号”（Prestige）燃油水容组分（WAF）的扁藻（*Tetraselmis* sp.）。同时，还利用贻贝鳃组织测定了乙酰胆碱酯酶（AChE, EC 3.1.1.7）活性和脂质过氧化（LP）水平，分别作为神经毒性和氧化应激损伤的指示指标。在暴露2、4、7和10天后，贻贝体内选定多环芳烃（2至6环PAHs）的生物蓄积未表现出任何显著趋势；其中2至3环PAHs占比最高（51%）。显著的（p
