Mechanisms of Toxicity and Metabolism is the sixth volume of the proceedings of the Sixth International Congress of Pharmacology, organized by the Finnish Pharmacological Society and held in Helsinki, Finland, on July 20-25, 1975. Contributors focus on the findings concerning the mechanisms of toxicity and metabolism and the developments in pharmacology and related areas of research. This volume has 24 chapters divided into four sections. After discussing the developmental aspects of drug metabolism and enzyme inhibitors of microbial origin, this book turns its attention to the interrelationships among various enzyme systems and physiological processes that are known to affect the distribution and metabolism of drugs. This text also highlights the reaction mechanisms of cytochrome P-450; the link between microsomal drug oxidation and glucuronidation; and the pharmacokinetics of the first pass effect. The reader is then introduced to the toxicity of food additives and the toxicity and metabolism of plasticizers and plastics. This volume concludes with a chapter that evaluates some of the biochemical and pharmacologic effects of di-2-ethylhexyl phthalate (DEHP). This book will appeal to scientists representing all the major areas of pharmacology, including clinical pharmacology and toxicology, as well as to internists, psychiatrists, neurologists, and anesthesiologists.

The new field of toxicogenomics presents a potentially powerful set of tools to better understand the health effects of exposures to toxicants in the environment. At the request of the National Institute of Environmental Health Sciences, the National Research Council assembled a committee to identify the benefits of toxicogenomics, the challenges to achieving them, and potential approaches to overcoming such challenges. The report concludes that realizing the potential of toxicogenomics to improve public health decisions will require a concerted effort to generate data, make use of existing data, and study data in new waysâ€"an effort requiring funding, interagency coordination, and data management strategies.

The EPA commissioned The National Academies to provide advice on the vexing question of whether and, if so, under what circumstances EPA should accept and consider intentional human dosing studies conducted by companies or other sources outside the agency (so-called third parties) to gather evidence relating to the risks of a chemical or the conditions under which exposure to it could be judged safe. This report recommends that such studies be conducted and used for regulatory purposes only if all of several strict conditions are met, including the following: The study is necessary and scientifically valid, meaning that it addresses an important regulatory question that can't be answered with animal studies or nondosing human studies; The societal benefits of the study outweigh any anticipated risks to participants. At no time, even when benefits beyond improved regulation exist, can a human dosing study be justified that is anticipated to cause lasting harm to study participants; and All recognized ethical standards and procedures for protecting the interests of study participants are observed. In addition, EPA should establish a Human Studies Review Board (HSRB) to evaluate all human dosing studiesâ€"both at the beginning and upon completion of the experimentsâ€"if they are carried out with the intent of affecting the agency's policy-making.

Mechanisms of Drug Toxicity, Volume 4 presents the proceedings of the 3rd International Pharmacological Meeting held in Sao Paulo, Brazil in 1966. The book discusses the drug-induced pathobiotic effects; the mechanisms of adverse reactions; and enzyme induction in the mechanism of chronic toxicity. The text also describes the influence of inducing substances on the growth of liver and microsomal electron transport systems; the quantitative aspects of chronic toxicity; and the facts and fallacies in predicting drug effects in human.

First Published in 1995: Written by specialists in their fields, this book contains short reviews intended to highlight points of growing interest in mechanistic toxicology. The first section considers selected aspects of molecular mechanisms, including selectivity of toxic agents and repair processes in the nervous system, toxicity of oxygen, fibers and aflatoxins. The second section discusses the interactions of carcinogens with DNA, and other targets, and their relevance to both molecular dosimetry of exposure and development of cancer. The final part is concerned with cellular and genetic aspects and includes coverage of some of the most recent and rapidly developing problems in toxicology.

Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.

The aim of this text is to examine the physiological development of the fetus. It allows the reader to study the unique pharmacokinetic and metabolic features of newborns and gives specific examples of drug metabolism in the newborn. The purpose of this book is to enhance the current knowledge of pharmacology of the newborn by observing the embryo and placenta in normal and abnormal development, placental transfer of drugs, metabolic pathways, and metabolism of specific drugs such as theophylline, benzodiazepines, and antibiotics. This is a useful book for those involved in pediatric research, pharmacology, toxicology, experimental therapeutics and biology.
