Toxicologic Pathology
Author: Pritam S. Sahota
Publisher: CRC Press
ISBN: 0429997469
Category : Medical
Languages : en
Pages : 1224
Book Description
Following the success of the first edition, this book is designed to provide practical and timely information for toxicologic pathologists working in pharmaceutical drug discovery and development. The majority of the book (Organ Systems) will provide detailed descriptions of histopathological lesions observed in drug development. In addition, it will provide information to assist the pathologist in making determinations of the origin of lesions as well as its relevance to human risk. Toxicologic Pathology: Nonclinical Safety Assessment, Second Edition includes 2 new concept chapters. The first of the new chapters address approaches for the evaluation of unique therapeutic modalities such as cell therapies, gene therapies, and gene expression knockdown therapies. While these still represent new developing therapeutic approaches, there has been significant experience with the therapeutic modalities in the last 5 years. The second new chapter addresses the nonclinical safety assessment of medical devices, a topic of increasing importance that was not addressed in a unique chapter in the first edition. The other concept chapters have been updated and cover important topics including the overview of drug development; principles of nonclinical safety assessment; an introduction to toxicologic pathology; techniques used in toxicologic pathology, clinical pathology, toxicokinetics, and drug development toxicogenomics; and spontaneous lesions. The 13 organ system chapters provide the specifics related to pathologic characteristics, differential diagnosis, and interpretation of toxic responses in each organ system. These chapters are specifically important for the bench pathologist but also for the toxicologist who interacts with pathologists and function as study toxicologists and project team representatives in the drug development arena.

The Paris System for Reporting Urinary Cytology
Author: Dorothy L. Rosenthal
Publisher: Springer
ISBN: 3319228641
Category : Medical
Languages : en
Pages : 177
Book Description
This book describes a novel and proven approach to cytologically classify urinary samples for the detection of bladder cancer and lesions of the upper urinary tract. The new method is based on the collective experience of knowledgeable cytopathologists who have tested the terminology within their own laboratories for reproducibility and predictability of neoplasms of the urinary tract. Accompanying the written criteria for each diagnostic category are meticulously photographed exemplars of the cellular features, with cogently annotated descriptions of the photographs. The book thereby performs as an atlas for microscopists involved in diagnostic cytopathology at all levels of their education. Included in the targeted readership are experienced pathologists, cytotechnologists, and students of both professional groups. The new terminology also considers the clinical aspects of patient management. Written by experts in the field who convened at the 18th International Congress of Cytology in Paris, The Paris System for Reporting Urinary Cytology presents a global standard for reporting and a new philosophic approach that maximizes the strengths of detecting the potentially lethal high grade lesions by urinary cytology, and recognizes without apology the inability to reliably detect the low grade lesions in urinary cytology. The Concept has been endorsed by the American Society Of Cytopathology, and the International Academy of Cytology.

Haschek and Rousseaux's Handbook of Toxicologic Pathology
Author: Wanda M. Haschek
Publisher: Elsevier
ISBN: 0080491448
Category : Medical
Languages : en
Pages : 2160
Book Description
A comprehensive understanding of toxicologic pathology is essential for those in industry, academia, and government who make decisions concerning the safety and efficacy of drugs and chemicals. Toxicologic pathology relies heavily on the fields of both toxicology and pathology, which are well covered individually in various texts and references; however, there are few texts that address the field of toxicologic pathology. The Handbook of Toxicologic Pathology fills this void and is thus essential for all health professionals within or interacting with the field of toxicologic pathology. This two-volume set provides the reader with a single reference for toxicologic pathology. In volume I, the book covers toxicologic pathology in its basic aspects, including its definition, the basic biochemical and morphologic mechanisms underlying the discipline, the basic practice of toxicologic pathology (including special techniques) and issues essential to the understanding of toxicologic pathology such as risk assessment, experimental design, and statistical analysis. Next, the book moves to specific issues affecting the "practice" toxicologic pathology, including issues such as knowledge management, regulatory affairs and writing pathology reports. Finally, Volume I closes with several chapters that deal with specific classes of environmental toxicants such as endocrine disruptors and heavy metals. Volume II addresses the toxicologic pathology in a thoroughly standardized systems manner, addressing the basic structure and function of a particular organ system, its response to toxic injury, mechanisms of injury and methods of evaluation of such injury. Key Features * Easy to find, up-to-date reference information * Graphic and photographic plates * Current hot topics and anticipated changes in toxicologic pathology * Standardized chapter format * Topics that are addressed in both a broad and deep manner, resulting in a stand alone text * Added coverage of important environmental toxicants * Chapters authored by internationally recognized experts and peer-reviewed

Principles and Methods of Toxicology, Fifth Edition
Author: A. Wallace Hayes
Publisher: CRC Press
ISBN: 9780849337789
Category : Medical
Languages : en
Pages : 2304
Book Description
Founded on the paradox that all things are poisons and the difference between poison and remedy is quantity, the determination of safe dosage forms the base and focus of modern toxicology. In order to make a sound determination there must be a working knowledge of the biologic mechanisms involved and of the methods employed to define these mechanisms. While the vastness of the field and the rapid accumulation of data may preclude the possibility of absorbing and retaining more than a fraction of the available information, a solid understanding of the underlying principles is essential. Extensively revised and updated with four new chapters and an expanded glossary, this fifth edition of the classic text, Principles and Methods of Toxicology provides comprehensive coverage in a manageable and accessible format. New topics include 'toxicopanomics', plant and animal poisons, information resources, and non-animal testing alternatives. Emphasizing the cornerstones of toxicology-people differ, dose matters, and things change, the book begins with a review of the history of toxicology and followed by an explanation of basic toxicological principles, agents that cause toxicity, target organ toxicity, and toxicological testing methods including many of the test protocols required to meet regulatory needs worldwide. The book examines each method or procedure from the standpoint of technique and interpretation of data and discusses problems and pitfalls that may be associated with each. The addition of several new authors allow for a broader and more diverse treatment of the ever-changing and expanding field of toxicology. Maintaining the high-quality information and organizational framework that made the previous editions so successful, Principles and Methods of Toxicology, Fifth Edition continues to be a valuable resource for the advanced practitioner as well as the new disciple of toxicology.
