Abstract

Background: In this study, the effect of heavy metals accumulation influence was evaluated on adult crayfish Procambarus clarkii (Decapoda, Astacidea) collected from three different Governmental locations (Kafr El-Shaikh, El-Menofya, and El-Gharbiya) of the Egyptian Delta. The activity of super oxidase dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) of gills, hepatopancreas, and muscle tissue were measured. SDS Polyacrylamide gel electrophoresis (SDS-PAGE) and West blotting technique were performed to detect MT Protein expression.

Results: The results revealed that Kafr El-Shaikh reflected the highest Superoxide dismutase (SOD), Catalase, and Glutathione S-transferase (GST) activity levels (97.2 u/100 mg, 28.5 u/100 mg, and 8.3 nmol mg (-1) protein min (-1) respectively. Superior protein polymorphism % (30%) remarked collected Freshwater crayfish P. clarkii from Kafr El-Shaikh location. Varied protein polymorphism % was shown between collected crayfish from El-Menofya, and El-Gharbiya locations (5.5 and 6.2 respectively) Increasing Metallothioneins intensity (15.4%) for collected Freshwater crayfish Procambarus clarkii from Kafr El-Shaikh Location.

Conclusion: Heavy metal stress influences antioxidant status and also induces increasing Metallothioneins intensity, especially samples that were collected from the Kafr El-Shaikh area.

从埃及三角洲地区的三个地点收集的淡水重金属积累对克氏原核生物氧化应激、金属硫蛋白生物合成和组织病理学的影响的评估（Girard，1985）。

背景：在本研究中，评估了重金属积累影响对从埃及三角洲三个不同政府地点（Kafr El Shaikh、El Menofya和El Gharbiya）采集的克氏原螯虾（Decapoda、Astacida）的影响。测定了鳃、肝胰腺和肌肉组织超氧化物歧化酶（SOD）、过氧化氢酶（CAT）和谷胱甘肽过氧化物酶（GPX）的活性。采用SDS聚丙烯酰胺凝胶电泳（SDS-PAGE）和West印迹技术检测MT蛋白的表达。结果：Kafr-El-Shaikh表现出最高的超氧化物歧化酶（SOD）、过氧化氢酶和谷胱甘肽S-转移酶（GST）活性水平，分别为97.2 u/100 mg、28.5 u/100 mg和8.3nmol mg（-1）蛋白min（-1）。从Kafr-El-Shaikh地区采集的淡水克氏小龙虾具有较高的蛋白质多态性%（30%）。在El Menofya和El Gharbiya地区采集的小龙虾之间显示出不同的蛋白质多态性%（分别为5.5和6.2），特别是从Kafr El Shaikh地区采集的样本。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
