Natural Toxins


Book Description

Natural Toxins presents the proceedings of the 6th International Symposium on Animal, Plant and Microbial Toxins, held in Uppsala, Sweden on August 1979. This book presents the methods for detection, diagnosis, treatment, and prevention of diseases that natural toxins cause. Organized into 17 parts encompassing 84 chapters, this compilation of papers begins with an overview of the embryonic development, structure, and function of the compound oral glands of venomous and non-venomous snakes in comparison with other exocrine glands. This text then examines the occupational hazards of snakebites in both agriculture and fishing in the Asian areas. Other chapters consider the toxicity and immunological relationships among venoms of several Agkistrodon species. This book discusses as well the characterization of cytotoxins and their mechanisms of action upon model lipid and cell membrane systems. The final chapter deals with neurotoxins as tools for the characterization of molecular components involved in nerve impulse propagation. This book is a valuable resource for biochemists, toxicologists, and pharmacologists.




Animal, Plant, and Microbial Toxins


Book Description

During the past two decades, research on animal, plant, and microbial toxins has expanded rapidly, and new and exciting information has appeared to clarify both the clinical and therapeutic aspects of intoxication and, even more impor tant, to help us understand more exactly the structure and the mode of action of toxins on a molecular basis. Because of the interdisciplinary nature of toxin research, it is of vital impor tance that workers specializing in its different aspects should make a particular effort to exchange and keep up with new developments in this rapidly-expanding field. This has been one of the main purposes of the series of international meetings that have been held over the past ten years. The increasing interest in the results of toxin research can be explained partly by the growing general preoccupation with pollution and its toxic effects, which means that more anq more specialists in other fields are finding it necessary to keep in touch with current research into naturally occurring toxins. The papers in these volumes were presented at the Fourth International Symposium on Animal, Plant and Microbial Toxins, organized by the Inter national Society on Toxicology, held in Tokyo in September, 1974. The editors have decided to include both original reports and review articles, arranged according to disciplines. Editing has been kept to the minimum necessary for adequate comprehension of the materials.

Snake Venoms


Book Description

The past decade has been a period of explosion of knowledge on the chemistry and pharmacology of snake toxins. Thanks to the development of protein chemistry, nearly a hundred snake toxins have been purified and sequenced, representing one of the largest families of sequenced proteins. Moreover, the mode of action of these toxins has been largely elucidated by the concerted efforts of pharmacologists, electro physiologists, and biochemists. As a result of these studies, some of the snake toxins, e.g., a-bungarotoxin and cobra neurotoxins, have been extensively used as specific markers in the study of the acetylcholine receptors. Indeed, without the discovery of these snake toxins, our knowledge of the structure and function of nicotinic acetylcholine receptors would not have advanced so rapidly. The contribution of snake venom research to the biomedical sciences is not limited to the study of cholinergic receptors. Being one of the most concentrated enzyme sources in nature, snake venoms are also valuable tools in biochemical research. Venom phosphodiesterase, for example, has been widely used for structural studies of nucleic acids; proteinase, for the sequence studies of proteins and pep tides ; phospholipase A , for lipid research; and L-amino acid oxidase for identifying optical z isomers of amino acids. Furthermore, snake venoms have proven to be useful agents for clarifying some basic concepts on blood coagulation and some venom enzymes, e.g., thrombin-like enzymes and pro coagulants have been used as therapeutic agents.




Bad Bug Book


Book Description

The Bad Bug Book 2nd Edition, released in 2012, provides current information about the major known agents that cause foodborne illness.Each chapter in this book is about a pathogen—a bacterium, virus, or parasite—or a natural toxin that can contaminate food and cause illness. The book contains scientific and technical information about the major pathogens that cause these kinds of illnesses.A separate “consumer box” in each chapter provides non-technical information, in everyday language. The boxes describe plainly what can make you sick and, more important, how to prevent it.The information provided in this handbook is abbreviated and general in nature, and is intended for practical use. It is not intended to be a comprehensive scientific or clinical reference.The Bad Bug Book is published by the Center for Food Safety and Applied Nutrition (CFSAN) of the Food and Drug Administration (FDA), U.S. Department of Health and Human Services.




Pharmacology - Volume II


Book Description

Pharmacology is a component of Encyclopedia of Biological, Physiological and Health Sciences in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Pharmacology is the study of the actions of chemicals on the body and most usually it is defined as chemicals that can have a therapeutic action to treat disease. Since it looks at the interaction between chemicals and body systems pharmacology utilizes the basic disciplines of chemistry, biochemistry, physiology, pathology and microbiology in its practice. Pharmacology is a foundation science for pharmacy which is the rational prescribing of drugs to treat disease and the foundation science for toxicology which is the study of the toxic actions of chemicals on the body. The two volumes are organized in groups of chapters as follows: The first group of chapters discuss pharmacological principles and these include chapters on Pharmacodynamics; Pharmacokinetics, Neuropharmacology, Autonomic Pharmacology and Clinical Pharmacology. The second group of chapters discusses the processes of Drug discovery and the Safety requirements for drugs to be used therapeutically and include Drug Discovery and Safety Pharmacology assessment. The largest group of chapters discuss different therapeutic areas and include Cardiovascular and renal pharmacology; Endocrine pharmacology; Neuropsychopharmacology; Pulmonary Pharmacology; Gastrointestinal pharmacology; Poisons venoms and toxins; Drugs on skeletal muscle; the Pharmacotherapy of inflammation; Reproductive pharmacology; Pain pharmacology and analgesia. The final group of chapters discuss new approaches and include Pharmacogenetics and pharmacogenomics; Immunopharmacology and Gene therapy. These two volumes are aimed at the following a wide spectrum of audiences from the merely curious to those seeking in-depth knowledge: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
