Biological Basis of Detoxication focuses on the biological processes involved in detoxication, with emphasis on the biochemistry of the removal of xenobiotics from an organism. Topics range from the formation of toxic metabolites and compounds that are not metabolized at all to the tissue distribution and nutritional considerations, the kinetics and mechanisms of the metabolic and excretory processes, and the integration of xenobiotic metabolism in the activation and detoxication of carcinogens. Organized into 14 chapters, this book begins with an overview of the enzymatic basis for the metabolic activation of foreign compounds in forming reactive chemical intermediates. The first few chapters discuss the identification of reactive electrophiles derived from xenobiotics, intratissue distribution of activating and detoxicating enzymes, enzymatic and non-enzymatic modes of xenobiotic metabolism, and unmetabolized compounds. The middle chapters explore the biological basis of detoxication of oxygen free radicals, physiologic and kinetic aspects of the fate of xenobiotics, excretion of xenobiotics, and effects of nutrition on detoxication. The remaining chapters look at the relationships between the enzymes of detoxication and host defense mechanisms, metabolic basis of target organ toxicity, the enzymatic factor in selective toxicity, and intraindividual and interindividual variations in rates of hepatic metabolism of exogenous chemicals. Pharmacologists, toxicologists, and biochemists will find this book highly informative.

The area of food toxicology currently has a high profile of interest in the food industry, universities, and government agencies, and is certainly of great concern to consumers. There are many books which cover selected toxins in foods (such as plant toxins, mycotoxins, pesticides, or heavy metals), but this book represents the first pedagogic treatment of the entire range of toxic compounds found naturally in foods or introduced by industrial contamination or food processing methods. Featuring coverage of areas of vital concern to consumers, such as toxicological implications of food adulteration (as seen in ethylene glycol in wines or the Spanish olive oil disaster) or pesticide residues, Introduction to Food Toxicology will be of interest to students in toxicology, environmental studies, and dietetics as well as anyone interested in food sources and public health issues. The number of students who are interested in toxicology has increased dramatically in the past several years. Issues related to toxic materials have received more and more attention from the public. The issues and potential problems are reported almost daily by the mass media, including television, newspapers, and magazines. Major misunderstandings and confusion raised by those reports are generally due to lack of basic knowledge about toxicology among consumers. This textbook provides the basic principles of food toxicology in order to help the general public better understand the real problems of toxic materials in foods. Principles of toxicology Toxicities of chemicals found in foods Occurrence of natural toxins in plant and animal foodstuffs Food contamination caused by industry Toxic chemicals related to food processing Food additives Microbial toxins in foods

This two-volume set provides essential information on the general princi-ples of target organ toxicity. Pharmacokinetics, metabolic activation and key defense mechanisms, excretion, species variation, and tissue-specific biochemistry are explored comprehensively. These general principles are then illustrated using specific examples of toxicity to different target organs and systems. DNA modifi-cation and repair in tumor induction, and specificity in tumor initiation are also examined. Of primary interest to toxicologist, pharma-cologists, biochemists, and environmental toxicologists.

Research into the biochemical basis of toxicology has expanded rapidly over recent years, amidst concerns over the adverse effects of drugs, environmental pollution and occupational hazards. Following on from the acclaimed first two editions of Principles of Biochemical Toxicology, John Timbrell has expanded the text to include: summary sections questions and model answers thoroughly revised artwork These features, plus the new easy-to-read format will make biochemical toxicology more accessible to undergraduates and postgraduates coming across the subject for the first time, particularly when undertaking self-directed study. This comprehensive textbook provides a thorough explanation of dose-response relationships; disposition and metabolism; toxic responses to foreign compounds, and detailed examples to illustrate mechanisms of toxicity. There is also an expanded and updated bibliography, directing the reader to further reading if required. Students and lecturers will find the clear and concise approach, which established this book as the leading textbook in its field, an essential aid to learning and teaching.

This text focuses on the biological interactions of sulphur compounds which arise specifically from the presence of the sulphur atom within the molecule. The book opens with introductory chapters on the chemistry and biology of sulphur, before tackling the field by introducing compounds which share a common chemical combination. In general, following a description of the uses and impact upon the biological field, specific chemical group characteristics are discussed together with the biological activity and structure-activity relationships where known. The toxicity of such compounds, their consequences in biochemical and clinical terms, and their mechanisms of biological interaction are then addressed.

Metabolic Basis of Detoxication: Metabolism of Functional Groups considers the possible fates of the relatively circumscribed number of functional groups that xenobiotics bear. An understanding of the possible reactions, and the chemical and biological factors influencing them, will contribute to the overall predictability of the fate of "real" molecules. This approach attempts to knit together the understanding of metabolic pathways with that of the enzymes that catalyze the specific steps. The book contains 18 chapters and begins with a discussion of the biological oxidation of carbon atoms. This is followed by separate chapters on the metabolism of halogenated aliphatic hydrocarbons, aryl halides, heterocyclic rings, alcohols, aldehydes, and ketones. Subsequent chapters cover oxidative processes such as metabolic dealkylations and biological oxidation at nitrogen centers; the reduction of nitro and azo compounds and tertiary amine N-oxides; the oxidation, alkylation, acylation, and glycosylation of mercaptans; epoxide metabolism; and conjugation of phenols. The book aims to inform and interest the pharmacologist and toxicologist concerning the biochemical aspects and to orient the biochemist to the pharmacological insights required in dealing with the metabolism of xenobiotics.
