摘要

环境污染是对生物行为和生理昼夜节律的威胁。研究了斑马鱼Danio rerio的日常游泳活动节奏，以评估来自墨西哥勒玛河的水的毒性，当它流经瓜纳华托州萨拉曼卡市时。急性暴露于污染水体3 d后，检测各组组织中乙酰胆碱酯酶活性及氧化应激。暴露在受污染的水中会大大降低强度，并改变游泳活动的日常模式。余弦分析显示对中膜和节律的鲁棒性有影响，组织分析显示对AChE有负面影响或增加氧化应激。分析水中离子Al、P、F−、po43 -、so42 -的浓度均在官方参考文献中确定。我们讨论了斑马鱼的日常游泳活动有助于检测污染环境中的水质。

The daily locomotor activity profile of Zebrafish Danio rerio is affected when exposed to polluted water from Lerma River (Guanajuato, Mexico)

ABSTRACT Environmental pollution is a threat to circadian rhythms of behaviour and physiology of organisms. The daily rhythm of swimming activity in zebrafish Danio rerio was studied to evaluate the toxicity of water from Lerma River, in Mexico, as it passed through the city of Salamanca, Guanajuato. Swimming activity along 3 days of acute exposure to polluted water, and then, the activity of the enzyme acetylcholinesterase and the oxidative stress in homogenized tissue was tested. Exposure to polluted water drastically reduces magnitude and alters the daily pattern of swimming activity. Cosinor analysis shows effect on mesor and robustness of rhythms, Tissue analysis showed a negative effect on AChE or an increase on oxidative stress. The analysis of water ions Al, P, F−, PO4 3-, SO4 2- in concentrations above the established in the official references. We discuss that daily swimming activity in zebra fish is useful to test water quality in polluted environments.

期刊介绍： The principal aim of Biological Rhythm Research is to cover any aspect of research into the broad topic of biological rhythms. The area covered can range from studies at the genetic or molecular level to those of behavioural or clinical topics. It can also include ultradian, circadian, infradian or annual rhythms. In this way, the Editorial Board tries to stimulate interdisciplinary rhythm research. Such an aim reflects not only the similarity of the methods used in different fields of chronobiology, but also the fact that many influences that exert controlling or masking effects are common. Amongst the controlling factors, attention is paid to the effects of climate change on living organisms. So, papers dealing with biometeorological aspects can also be submitted. The Journal publishes original scientific research papers, review papers, short notes on research in progress, book reviews and summaries of activities, symposia and congresses of national and international organizations dealing with rhythmic phenomena.
