Although the anticholinesterase (anti-ChE) agents have only limited applica tions in therapy, and from the viewpoint of practical significance they are more appropriately classified as toxic compounds or insecticides than as drugs, in their capacity of pharmacological tools they have few equals. The concept of neuro humoral transmission was originally established largely from experiments in which physostigmine, or eserine, was employed to protect acetylcholine (ACh), the trans mitter of the cholinergic nerves, from rapid hydrolytic destruction by acetyl cholinesterase (AChE) and other cholinesterases (ChE's). Since then, a great num ber of additional reversible and irreversible anti-ChE agents also have been indis pensable in studies of synaptic and neuroeffector transmission, and of other physiological processes. At the same time, there is practically no other class of compounds for which a mechanism of pharmacological action can be described in such concrete biochemical and physiological terms. Consequently, it is not sur prising that a huge literature has developed on these several closely interdependent topics. The assembling anrl proper correlation of this material for the present volume has taken the collaborative efforts of over two dozen . investigators. It iR believed that their contributions to this end will prove invaluable to future in vestigators in providing a ready, inclusive source of established information, in defining areas where further studies are indicated, and in preventing unnecessary duplication of past work. How well these aims have been accomplished will be for time and the reader to judge.

Behavioral toxicology is a young discipline in the United States; so young, in fact, that this is one of its first books. Behavioral questions are bound to play a major role in future scientific work and governmental decisions involving the health effects of environmental contaminants and other chemicals. This role springs from two key problems that face scientists and public agencies required to set acceptable exposure standards or to determine criteria for the toxicity of therapeutic chemicals: How do you evaluate effects that may show up only as subtle functional disturbances? And how do you de tect toxic effects early enough so that they may still be reversible, before they produce major damage? The contributions in this book come from a collection of scientists whose interests span a wide variety of problem areas. The focus is largely on me thodological issues because they represent the most immediate concern of the discipline. We expect that this collection of papers will represent a useful source book for behavioral toxicology for some time. For the past few years, the University of Rochester's Department of Radiation Biology and Biophysics has sponsored a series of international conferences on chemical toxicity, partly as a response to concern over the con sequences to health of the rich chemical soup in which we live. This book is based upon presentations made to the fifth of the series. Held in June, 1972, it was the first formal meeting devoted to behavioral toxicology in this country.

This text/reference book provides the most comprehensive coverage of anticholinesterase compounds (Organophosphates and Carbamates), which constitute the largest number of chemicals that are primarily used as insecticides in agriculture, industry, and around the home/garden. Some OPs (nerve agents) have been used in chemical warfare and terrorist attacks, while some OPs and CMs have been recommended as therapeutic agents in human medicine as well as in veterinary medicine. Many chemicals of both classes are extremely toxic and lack selectivity, thus their inadvertent/accidental use continues to pose a threat to human and animal health, aquatic systems and wildlife. These anticholinesterase agents produce a variety of toxicological effects in target and nontarget organs. In light of this complexicity, this multi-authored book is written by the well known scientists from many countries. The book is organized into nine sections, with a total of 49 chapters, to provide in-depth knowledge on various aspects of OP and CM compounds, including their use, classification, mechanism-based toxicity, and prophylactic and therapeutic measurements. Several chapters are written with special emphasis to cover timely topics, such as chemical warfare agents, physiologically-based pharmacokinetic modeling, structure and function of cholinesterases, paraoxonase, carboxylesterases; developmental neurotoxicity, the intermediate syndrome, oxidative stress, endocrine disruption, and DNA damage/gene expression and carcinogenesis. Section-VI with 5 chapters is specifically devoted to risk assessment, and safety and regulatory guidelines for pesticides. - Describes everything you need to know about Organophosphates and Carbamates - Extensively covers pesticides, nerve agents, therapeutic drugs, and flame retardants - Describes epidemiology of the world's major disasters involving Organophosphates and Carbamates - Covers animal, human, aquatic, and wildlife toxicity of Anticholinesterases - Insights into in-depth cholinergic and noncholinergic mechanisms of toxicity - Describes recent advancements in cholinesterases, paraoxonases, carboxylesterases, oxidative stress, endocrine disruption, cardiac and pulmonary toxicity, and carcinogenesis - Provides in vitro and in vivo models for neurotoxicity testing - Integrates knowledge of studies in lab animals and humans - Offers risk/safety assessment and national/international guidelines for permissible levels of pesticide residues - Describes management of Anticholinesterase poisoning in humans

To understand Alzheimer's disease (AD) is one of the major thrusts of present-day clinical research, strongly supported by more fimdamental cellular, biochemical, immunological and structural studies. It is these latter that receive attention within this book. This compilation of 20 chapters indicates the diversity of work currently in progress and summarizes the current state of knowledge. Experienced authors who are scientifically active in their fields of study have been selected as contributors to this book, in an attempt to present a reasonably complete survey of the field. Inevitably, some exciting topics for one reason or another have not been included, for which we can only apologize. Standardization of terminology is often a problem in science, not least in the Alzheimer field; editorial effort has been made to achieve standardization between the Chapters, but some minor yet acceptable personal / author variation is still present, i. e. P-amyloid/amyloid-P; Ap42/Apl-42/APi. 42! The book commences with a broad survey of the contribution that the range of available microscopical techniques has made to the study of Alzheimer's amyloid plaques and amyloid fibrillogenesis. This chapter also serves as an Introduction to the book, since several of the topics introduced here are expanded upon in later chapters. Also, it is significant to the presence of this chapter that the initial discovery of brain plaques, by Alois Alzheimer, utilized light microscopy, a technique that continues to be extremely valuable in present-day AD research.

At the Fifth International Neuromuscular Meeting held in Tokyo in 1994, leading experts in the field came together to discuss the physiology and pharmacology of neuromuscular receptor sites and neuromuscular blocking agents (NBAs). The proceedings of the meeting present a review of the history of muscle relaxants and a comprehensive examination of recent research, with a primary focus on clinical considerations. Among the topics covered by specific chapters are aspects of the neuromuscular junction (NMJ), pharmacokinetics, metabolism and metabolites of neuromuscular blocking agents, and drug interaction. Presenting the most up-to-date knowledge of the physiology and pharmacology of the NMJ and NBAs, this volume will be highly valuable to clinicians and researchers in anesthesiology, physiology, and pharmacology.
