The effect of size and tissue parts as well as site locations on a suite of six anti-oxidative biochemical markers, viz. the enzyme degrading neural transmitters acetylcholinesterase (AChE), the Phase II transforming enzyme glutathione-S-transferase (GST), the anti-oxidative enzymes superoxide dismutase (SOD) and catalase (CAT), the lipid metabolite malondialdehyde (MDA) and the ratio of CAT/MDA, in the bivalve mollusc, Perna viridis, was studied. Field mussels were collected from the piers of University of Science and Technology (UST), Pak Sha Wan or Hebe Haven (PS) and Sai Kung (SK) in Port Shelter, Hong Kong. Statistically, ANOVA showed that the activity of all six biochemical markers were generally tissue dependent, size independent and location dependent. Tukey multi comparison test indicated that the biochemical activities fell into two groups, with SK the highest activity group in most cases. The significance of these findings in relation to long-term coastal water biomonitoring is discussed.
研究了大小、组织部位以及位点位置对双壳贝类翡翠贻贝中一组六种抗氧化生化标志物的影响，即降解神经递质的乙酰胆碱酯酶（AChE）、II相转化酶谷胱甘肽-S-转移酶（GST）、抗氧化酶超氧化物歧化酶（SOD）和过氧化氢酶（CAT）、脂质代谢产物丙二醛（MDA）以及CAT/MDA比值。从香港牛尾海的香港科技大学（UST）码头、白沙湾或白沙澳（PS）以及西贡（SK）采集野外贻贝。统计分析表明，方差分析显示所有六种生化标志物的活性通常依赖于组织、不依赖于大小且依赖于位置。Tukey多重比较检验表明，生化活性分为两组，在大多数情况下，SK是活性最高的组。讨论了这些发现与长期沿海水体生物监测的相关性。
