Languages : en
Pages : 303
Book Description
The gastrointestinal tract is the most important of the three major routes of entry (and clearance) of xenobiotics and biologic entities into the bodies of mammals. As such, it is also the major route for administration of pharmaceuticals to humans. Gastrointestinal Toxicology, Second Edition describes the mechanism for entry and clearance of xenobiotics, as well as the barriers, immunologic and metabolic issues, and functions present in the GI tract. Appearing in this volume are also considerations of the microbiome and its actions and influence on the function of the GI tract and on the toxicity and pharmacodynamics of ingested substances (including nutrients, toxins, and therapeutics). These fifteen chapters written by experienced experts in the field address methods to evaluate GI function; specifics of GI function and toxicity assessment in canines and minipigs; classes of compounds with their toxicity; species differences; and the toxicity (and promise) of nanoparticles. Those needing to understand the structure, function, and methods of studying the GI tract will find this volume a singular source of reference.

Integrative Gastroenterology
Author: Gerard E. Mullin
Publisher: Oxford University Press
ISBN: 0190933062
Category : Medical
Languages : en
Pages : 689
Book Description
Digestive complaints have become increasingly common. Recent statistics show that gastrointestinal complaints account for nearly a third of all visits to primary care doctors and that nearly one in two Americans suffer from digestive disease. Millions more suffer from conditions such as migraine headaches, arthritis, mood disorders, chronic fatigue, asthma, allergies, and menstrual dysfunction, which are all related to a disorder in digestive health. Despite the evidence in support of integrative approaches to treatment and prevention of digestive symptoms, these approaches are largely overlooked in treating gastrointestinal disorders. Rather, treatment plans tend to be exclusively pharmacologically based and have appreciable toxicity. Integrative Gastroenterology, Second edition, is a comprehensive guide to helping health care practitioners understand and appreciate how to manage patients with gastrointestinal conditions integrating conventional and complimentary approaches. This text reviews the latest advances in science and research with regards to the gut microbiome, physiology, and interconnections between the gut and other organ systems. Coverage includes a diverse range of treatment methods, such as probiotics, meditation, massage, yoga, supplements, special diets, energy medicine, homeopathy, and acupuncture, as well as a special section devoted to mind-body medicine in digestive health and disease. In discussing unconventional treatments, the authors address many of the controversies that surround the remedies.

Principles of Toxicology Testing, Second Edition
Author: Frank A Barile
Publisher: CRC Press
ISBN: 1842145282
Category : Medical
Languages : en
Pages : 368
Book Description
Nationally, toxicology programs have evolved from a traditional exploration of the chemistry and applied toxicity of chemicals and drugs to a more comprehensive study of toxicology and toxicology testing as independent entities. Consequently, the second edition of Principles of Toxicology Testing starts with basic toxicological principles, including absorption, distribution, metabolism, and elimination of toxins, including chemicals and drugs. The book then continues with animal (in vivo) and in vitro toxicology testing methods associated with toxicological analysis and preclinical drug development. As in the first edition, the book begins with an introduction into the fundamentals of toxicology (Section I) to prepare readers for the subsequent topics and continues through with a discussion of toxicokinetics and human risk assessment. This introductory material is useful in understanding the applications of toxicology testing. Section II describes the fundamental principles of toxicology testing in animals in greater detail. This section describes acute toxicity studies as well as subchronic and chronic studies performed on animals. Special emphasis is placed on study design and determination of classical indicators for acute and chronic testing, such as the LD50. The book examines other short- and long-term animal toxicity testing methodologies, including dermal, ocular, and reproductive toxicity testing. In addition, mutagenicity and carcinogenicity studies are also discussed in separate chapters. Section III introduces and discusses in vitro alternatives to animal toxicology tests. This section emphasizes cell culture methodology and cellular methods for acute systemic toxicity, target organ toxicity, and local toxicity. The contributors present the advantages and disadvantages of alternative methods. They also describe the use of high-throughput screening and its applications, the concepts of standardization and validation of in vitro techniques (especially large, organized validation efforts currently supported by US and EU regulatory agencies), and the theories supporting the development of in vitro methodologies. This second edition is a must-read for undergraduate and graduate toxicology students. Industrial and academic research centers will also find the text useful for establishing a toxicology testing laboratory.

Toxicology of the Gastrointestinal Tract
Author: Shayne C. Gad
Publisher: CRC Press
ISBN: 9780849327933
Category : Medical
Languages : en
Pages : 376
Book Description
Toxicology of the Gastrointestinal Tract focuses on the specifics of the mechanisms and adverse effects of xenobiotic agents and pharmaceuticals on the structure and function of the GI tract. The book focuses on a number of specific areas of intestinal research. Beginning with the well-recognized and major functions of nutrient absorption and its role as a protective barrier, the text elaborates on the expanding body of knowledge that relates to the intestines as a major metabolic and immunologic organ involved in the synthesis and degradation of both natural and foreign substances. It includes an overview of the function and dysfunction of the human absorptive process and the effects of microbial flora on these processes, as well as specific classes of toxicants that target the GI tract. The international panel of contributors presents a critical appraisal of the interactions of chemicals and drugs with the gastrointestinal system and the experimental methods and regions of research on which to focus future efforts. Providing a complete and multidisciplinary overview of the gastrointestinal system both in health and as it is involved in the toxicity of exogenous agents, Toxicology of the Gastrointestinal Tract brings together the current and growing knowledge of this critical organ system in a single volume.
