This book was released on 1977 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lethal and sublethal effects of fenitrothion, an organophosphate insecticide, were investigated in rainbow trout (Salmo gairdneri) embryos, sac fry, fingerlings, and adults. Embryos first exhibited cholinesterase activity 14 days before hatch. Embryos and sac fry at various ages subjected to 34 mg/litre fenitrothion for 24 h under static exposure conditions first exhibited mortality 6 days after hatch. A 24-h lethal concentration of 50 percent of organisms (LC50) of 3.4 mg/litre and a 96-h LC50 of 2.0 mg/litre were obtained using fingerlings exposed to fenitrothion in a flow-through system. Fingerlings surviving 96 h of exposure exhibited cholinesterase activities ranging from 13 to 25 percent of controls (brain) and 30 to 51 percent (skeletal muscle). Adult trout were monitored for electrocardiogram and respiratory responses to fenitrothion concentrations of 5.0, 1.0, and 0.5 mg/litre. At 5 mg/litre, heart rate decreased initially but recovered within 24 h. Cough frequency was directly related to fenitrothion concentration. Based on acute mortality tests, the embryological life stage was the least sensitive, the sac fry stage was intermediate, and the life stages of fingerlings and adults were the most sensitive. The sublethal responses, cholinesterase inhibition in fingerlings and the cough response in adult trout, were sensitive to 0.75 and 0.5 mg/litre fenitrothion.

Download or read book Fish Ecotoxicology written by Braunbeck and published by Birkhäuser. This book was released on 2013-03-07 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: In modern ecotoxicology, fish have become the major vertebrate model, and a tremendous body of information has been accumulated. This volume attempts to summarize our present knowledge in several fields of primary ecotoxicological interest ranging from the use of (ultra)structural modifications of selected cell systems as sources of biomarkers for environmental impact over novel approaches to monitoring the impact of xenobiotics with fish in vitro systems such as primary and permanent fish cell cultures, the importance of early life-stage tests with fish, the bioaccumulation of xenobiotics in fish, the origin of liver neoplastic lesions in small fish species, immunocytochemical approaches to monitoring effects in cytochrome P450-related biotransformation, the impact of heavy metals in soft water systems, the environmental toxicology of organotin compounds, oxidative stress in fish by environmental pollutants to effects by estrogenic substances in aquatic systems.

Book Synopsis Recent Trends in the Acetylcholinesterase System by : Mahira Parveen
Download or read book Recent Trends in the Acetylcholinesterase System written by Mahira Parveen and published by IOS Press. This book was released on 2005 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The enzyme acetylcholinesterase (AChE) has drawn the attention of scientist as it has played a striking role in Alzheimer's disease, Cardiac diseases and other diseases. A good discussion and overview document on AChE enzyme and its various aspects was felt lacking since a long time in the field of enzyme biochemistry as well as enzyme biotechnology and this publication fills this gap. Before this publication there was no data available on AChE enzyme inhibition, its kinetics, its peripheral sites, their role in catalytic and noncholinergic function of enzyme, ACh receptors, AChE and BuChE genes etc. All these topics together form a good basis for researchers and post graduate students in this field of interest. This book is a collection of recent advanced reports and data on AChE enzyme.
