Abstract

Abstract In this study, lead (Pb) and cadmium (Cd) were used as chemical stressors. Healthy A. testudineus were exposed to Pb (20, 30, and 40 mg/L) and Cd (3, 5, and 10 mg/L) for 7, 14, 21, and 28 days to assess the response of A. testudineus elicited by these metals. The tendency of Pb and Cd accumulation in the tissues of A. testudineus was as follows: gill >> liver > muscle for Pb and liver >> gill > muscle for Cd. Endocrine stress response was characterized by varying the levels of cortisol and glucose plasma. Exposure to both Pb and Cd caused significantly increase levels of plasma cortisol (p < 0.05), while blood glucose levels slightly increased at the beginning and then decreased sharply. Based on the erratic changes in levels of plasma cortisol and blood glucose, it can be concluded that exposure to high concentrations of Pb and Cd does not cause death; however, it adversely affects the interrenal and pancreatic activities of A. testudineus. Biochemical changes can be used as biomarkers for stress assessment and management in fish.

攀鲈暴露于水中高浓度铅和镉的积累和应激反应

摘要本研究以铅(Pb)和镉(Cd)作为化学应激源。将健康的绒螯蟹分别暴露于Pb(20、30和40 mg/L)和Cd(3、5和10 mg/L)环境7、14、21和28天，以评估这些金属对绒螯蟹的影响。铅和镉在龙家鲟组织中的蓄积趋势为:鳃>>肝>肌蓄积Pb，肝>>鳃>肌蓄积Cd。内分泌应激反应以血浆皮质醇和葡萄糖水平的变化为特征。铅、镉暴露均引起血浆皮质醇水平显著升高(p < 0.05)，血糖水平先小幅升高后急剧下降。根据血浆皮质醇和血糖水平的不稳定变化，可以得出结论，暴露于高浓度的铅和镉不会导致死亡;然而，它对豚鼠的肾间和胰腺活动有不利影响。生物化学变化可作为鱼类应激评估和管理的生物标志物。

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.
