Available in PDF, EPUB and Kindle. Book excerpt: Nervous system is in the most cases a likely target for the untoward effects of chemicals. The harmful consequences affect primarily the individual but may also considerably strain the whole society. The consumption of ethanol is a glaring example (National Institute on Alcohol Abuse and Alcoholism 1978). As ethanol, many organic liquids have similar immediate effects on the nervous system. The rapidity of the response suggests the involvement of the neuronal communication. The nervous system is also vulnerable to the depletion of oxygen, another common cause for the rapid deterioration of the brain function. It is quite impossible to list all the effects produced by the very large number of the individual chemicals. It would be more fruitful to try to understand the characteristics of the nervous system and the biochemical toxic mechanisms in the evaluation of the neurotoxicity of chemicals. Transfer of Xenobiotics in the Brain The adult central nervous system displays a functional barrier toward the blood-borne chemicals so that water-soluble compounds with an approximate molecular weight above 100 are largely prevented from directly entering the brain (Bradbury 1979). The functional barrier has morphological features typical to it and has a very close association of adjacent capillary cells separated by clefts of 12 A wide (Jacobs 1978). The nervous system capillaries are enveloped by glial cell tongues, and these pericytes contain contractile elements (Le Beux and Willemot 1978a, b) so that the capillaries can be constricted.

This book was released on 1987 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report examines the relationships between aging and exposure to environmental agents (including natural and man-made agents, as well as life-style factors). Several relationships must be considered--the impact of intermittent or lifelong exposure to environmental agents on the rate of aging, the impact of lifelong exposure on health status when one reaches more advanced age, and the special response of the aged compared with that of the young when exposed to environmental agents.
Download or read book Forging a Poison Prevention and Control System written by Institute of Medicine and published by National Academies Press. This book was released on 2004-09-16 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poisoning is a far more serious health problem in the U.S. than has generally been recognized. It is estimated that more than 4 million poisoning episodes occur annually, with approximately 300,000 cases leading to hospitalization. The field of poison prevention provides some of the most celebrated examples of successful public health interventions, yet surprisingly the current poison control "system" is little more than a loose network of poison control centers, poorly integrated into the larger spheres of public health. To increase their effectiveness, efforts to reduce poisoning need to be linked to a national agenda for public health promotion and injury prevention. Forging a Poison Prevention and Control System recommends a future poison control system with a strong public health infrastructure, a national system of regional poison control centers, federal funding to support core poison control activities, and a national poison information system to track major poisoning epidemics and possible acts of bioterrorism. This framework provides a complete "system" that could offer the best poison prevention and patient care services to meet the needs of the nation in the 21st century.
Download or read book Toxicology in Antiquity written by and published by Academic Press. This book was released on 2018-10-22 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toxicology in Antiquity provides an authoritative and fascinating exploration into the use of toxins and poisons in antiquity. It brings together the two previously published shorter volumes on the topic, as well as adding considerable new information. Part of the History of Toxicology and Environmental Health series, it covers key accomplishments, scientists, and events in the broad field of toxicology, including environmental health and chemical safety. This first volume sets the tone for the series and starts at the very beginning, historically speaking, with a look at toxicology in ancient times. The book explains that before scientific research methods were developed, toxicology thrived as a very practical discipline. People living in ancient civilizations readily learned to distinguish safe substances from hazardous ones, how to avoid these hazardous substances, and how to use them to inflict harm on enemies. It also describes scholars who compiled compendia of toxic agents. New chapters in this edition focus chiefly on evidence for the use of toxic agents derived from religious texts. Provides the historical background for understanding modern toxicology Illustrates the ways previous civilizations learned to distinguish safe from hazardous substances, how to avoid the hazardous substances and how to use them against enemies Explores the way famous historical figures used toxins New chapters focus on evidence of the use of toxins derived from religious texts
Download or read book Poisoning in the Modern World written by Ozgur Karcioglu and published by BoD – Books on Demand. This book was released on 2019-06-19 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 400 years ago, Swiss alchemist and physician Paracelsus (1493-1541) cited: "All substances are poisons; there is none that is not a poison. The right dose differentiates a poison from a remedy." This is often condensed to: "The dose makes the poison." So, why are we overtly anxious about intoxications?In fact, poisons became a global problem with the industrial revolution. Pesticides, asbestos, occupational chemicals, air pollution, and heavy metal toxicity maintain high priority worldwide, especially in developing countries. Children between 0 and 5 years old are the most vulnerable to both acute and chronic poisonings, while older adults suffer from the chronic effects of chemicals. This book aims to raise awareness about the challenges of poisons, to help clinicians understand current issues in toxicology.
Download or read book History of Toxicology and Environmental Health written by Philip Wexler and published by Academic Press. This book was released on 2014-09-18 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, Toxicology in Antiquity II, continues to tell the story of the roots of toxicology in ancient times. Readers learn that before scientific research methods were developed, toxicology thrived as a very practical discipline. Toxicologists are particularly proud of the rich and storied history of their field and there are few resources available that cover the discipline from a historical perspective. People living in ancient civilizations readily learned to distinguish safe from hazardous substances, how to avoid these hazardous substances and how to use them to inflict harm on enemies. Volume II explores the use of poison as weapons in war and assassinations, early instances of air pollution, the use of hallucinogens and entheogens, and the role of the snake in ancient toxicology. Provides the historical background for understanding modern toxicology Illustrates the ways ancient civilizations learned to distinguish safe from hazardous substances, how to avoid the hazardous substances and how to use them against enemies Details scholars who compiled compendia of toxic agents

Download or read book Forensic Toxicology written by Susannah Davies and published by Royal Society of Chemistry. This book was released on 2019-03-15 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: New designer drugs, access to databases, and changing availability of samples for analysis have changed the face of modern forensic toxicology in recent years. Forensic Toxicology: Drug Use and Misuse brings together the latest information direct from experts in each sub-field of the discipline providing a broad overview of current thinking and the most innovative approaches to case studies. The text begins with an in-depth discussion of pharmacoepidemiology, including information on the value of nationwide databases in forensic toxicology. The use and abuse of drugs in driving, sport and the workplace are then discussed by industry experts who are conducting case work in their field. Not only are new drug groups discussed (NPS), but also their constantly changing impact on drug legislation. Synthetic cannabinoids, khat and mephodrone are discussed in detail. Following a section devoted to legislation and defence, readers will find comprehensive chapters covering sample choice reflecting the increasing use of hair and oral fluid, and also the less commonly used sweat and nail analysis. New and old case examples are compared and contrasted in the final part of the book, which will enable readers to understand how drugs impact on each other and how the interpretative outcome of a case are dependent on many aspects. From use of pharmaceutical drugs in a clinical setting, through smart drugs to new psychoactive drugs, this book documents the wide range in which drugs today are abused. This book will be an essential resource for postgraduate students in forensic toxicology, and for researchers in forensic toxicology laboratories who need the latest data and knowledge.
Download or read book Environmental Neurotoxicology written by National Research Council and published by National Academies Press. This book was released on 1992-02-01 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists agree that exposure to toxic agents in the environment can cause neurological and psychiatric illnesses ranging from headaches and depression to syndromes resembling parkinsonism. It can even result in death at high exposure levels. The emergence of subclinical neurotoxicity-the concept that long-term impairments can escape clinical detection-makes the need for risk assessment even more critical. This volume paves the way toward definitive solutions, presenting the current consensus on risk assessment and environmental toxicants and offering specific recommendations. The book covers: The biologic basis of neurotoxicity. Progress in the application of biologic markers. Reviews of a wide range of in vitro and in vivo testing techniques. The use of surveillance and epidemiology to identify neurotoxic hazards that escape premarket screening. Research needs. This volume will be an important resource for policymakers, health specialists, researchers, and students.

Download or read book Toxicity Testing in the 21st Century written by National Research Council and published by National Academies Press. This book was released on 2007-10-05 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in molecular biology and toxicology are paving the way for major improvements in the evaluation of the hazards posed by the large number of chemicals found at low levels in the environment. The National Research Council was asked by the U.S. Environmental Protection Agency to review the state of the science and create a far-reaching vision for the future of toxicity testing. The book finds that developing, improving, and validating new laboratory tools based on recent scientific advances could significantly improve our ability to understand the hazards and risks posed by chemicals. This new knowledge would lead to much more informed environmental regulations and dramatically reduce the need for animal testing because the new tests would be based on human cells and cell components. Substantial scientific efforts and resources will be required to leverage these new technologies to realize the vision, but the result will be a more efficient, informative and less costly system for assessing the hazards posed by industrial chemicals and pesticides.
