Comparative Pathophysiology and Toxicology of Cyclooxygenases


Book Description

The first thorough review of cyclooxygenase inhibitors, including their toxicity mechanisms and toxicopathological risks Cyclooxygenases (COXs) are enzymes responsible for the formation of an important class of biological mediators called prostanoids. Prostanoids such as prostaglandins mediate inflammatory and anaphylactic reactions. For those suffering from inflammation and pain, the pharmacological inhibition of COXs, with non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, can provide relief. Yet the use of NSAIDs can trigger toxicological effects as well, leading to potential health risks. Comparative Pathophysiology and Toxicology of Cyclooxygenases provides a comprehensive overview of how COX inhibitors affect various bodily systems, specifically the toxicity mechanisms triggered when the COX enzyme is inhibited. The book provides an introduction to the discovery of cyclooxygenases, their use as therapeutic agents, as well as an historical perspective. Shedding light on the differences in expression, pathophysiology, and toxicology of COX inhibitors across species, the book offers a systematic examination of the effects and pathophysiology of COX inhibitors and their mechanisms of toxicity, beginning with the GI tract. Subsequent chapters cover: The pathophysiology of COX inhibition on bone, tendon, and ligament healing COX inhibitors and renal system pathophysiology and mechanisms of toxicity The pathophysiologic role of COX inhibition in the ocular system COX inhibition and the respiratory and cardiovascular systems The book also sheds light on the latest research devoted to developing COX inhibitors with no adverse side-effects. The first book to offer a thorough comparative look at the toxicological effects of COX inhibitors throughout the body, this invaluable resource will help advance the research and development of safer and more effective COX drugs.




Toxicologic Pathology


Book Description

As drug development shifts over time to address unmet medical needs and more targeted therapies are developed, previously unseen pharmacological or off-target effects may occur in treatment. Designed to provide practical information for the bench toxicologic pathologist working in pharmaceutical drug research, Toxicologic Pathology: Nonclinical Safety Assessment presents a histopathologic description of lesions observed during drug development and discusses their implication in the drug development process. Divided into two sections, the book systematically assists pathologists in making a determination as to the origin and potential importance of a lesion and its relevance for assessing human risk. The first section includes eight "concept" chapters to orient pathologists in areas that are important for effective interaction with other pathologists as well as the many non-pathologists involved in drug development. The second section is made up of organ-based chapters, each including light microscopic and electron microscopic descriptions of pathological lesions, differential diagnoses, biological consequences, pathogenesis, mechanism of lesion formation, and the expected clinical pathology correlates. This volume presents critical information—both published and unpublished and gained through personal experience—to improve the quality of drug safety evaluation and to expedite and improve the efficiency of the process. This book is crafted to assist students, residents, and toxicologic pathologists in their early career phase by serving as a resource that can effectively be used as a ready reference next to the microscope. In addition, more experienced pathologists will find this volume to be invaluable during their assessments. The book is also a valuable reference for toxicologists to assist in understanding compound-related pathological findings and to provide background for working on a range of toxicological problems.

The book includes a new section describing the application of toxicologic pathology, such as diagnostic and forensic toxicologic pathology, environmental toxicologic pathology, experimental and industrial toxicologic pathology, and pathology issues in the design of toxicology studies. There are also new chapters on special senses (the eye and ear) and the biochemical and molecular basis of toxicity, among others. - Presents revised and updated information for each chapter on systems - Contains expanded sections on applied toxicologic pathology - Includes the essential information necessary to understand toxicologic pathology in an accessible language

Histopathology of Preclinical Toxicity Studies


Book Description

This work covers effectively all aspects of drug-induced pathology that may be encountered within preclinical toxicity studies. It fills a gap in the pathology literature relating to the preclinical safety assessment of new medicines. It systematically describes, in one volume, both spontaneous and drug induced pathology on an organ by organ basis. Information relevant to understanding the nature of pathological changes in pre-clinical studies and assessment of their relevance to the clinical investigation of new drugs is also covered. Numerous colour photographs are included that highlight and embellish the histopathological features that are described. It also contains many pertinent references to both human and animal pathology forming an essential basis for the assessment of drug-induced pathology.NEW TO THE THIRD EDITION:* Covers drug induced pathology in preclinical (animal) studies and their relevance for patients or volunteers in clinical studies* General comments to each chapter about the relevance of pathological findings to humans* Provides essential information that can help decide the relevance of particular lesions for patients

Toxicologic Pathology for Non-Pathologists


Book Description

This extensive volume began as a short course primarily geared toward toxicologists who want to expand their understanding of toxicologic pathology in order to be better study directors while also proving to be of great interest to other drug development scientists and regulatory reviewers. The overall goal is to help non-pathologists understand, contextualize, and communicate the pathology data and interpretations from the study pathologist in a practical and usable format. Within the book, readers will find an overview of general pathology concepts that include fundamental vocabulary and the basics of pathophysiological processes, along with numerous chapters devoted to pathology in specific organ systems as well as topics such as biomarkers, correlation of clinical pathology endpoints (chemistry and hematology) with microscopic changes, and well-known pathology findings for classes of toxic substances. Authoritative, practical, and comprehensive, Toxicologic Pathology for Non-Pathologists aims to help non-pathologists understand, converse in, and apply a basic understanding of pathology in their day-to-day careers.




How Tobacco Smoke Causes Disease


Book Description

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
