Book Description
Free radicals have been implicated in a entire host of different human disease states, which suggests that although they may not have a pivotal causal role, they are involved in the perpetuation of disease. In recentyears, it has become evident that although free radicals most certainly do have this role in perpetuating inflammatory reactions, they have perhaps a far more important role in acting as second messenger systems to maintain normal cell function. It is theperturbations of these reactions which pose the most intriguing therapeutic challenges. This volume deals with various basic mechanisms of free radical processes and injury. The emphasis in each case is on potential therapeutic strategies developing fromthis new knowledge.

Book Description
As in so many fields of scientific endeavour following the molecular biology revo lution, our knowledge of the role of radicals not only in pathological states, but in basic physiology has developed exponentially. Indeed, our evolving concepts have, like so many political parties, been forced into dramatic "V-turns" and contortions. Within our working lives, we have had to debate whether radicals made any con tribution to any pathology, whilst now it is difficult not to entertain the view that every physiological process is pivotally controlled by exquisitely sensitive radical reactions. Inflammation is, of course, an example of pathology evolving from physiology, and in this book we have called upon both scientists and clinicians who have research interests in the complex switching mechanisms that sustain these transi tions. The book as a whole explores, from a physiological standpoint, how deter ministic radical systems sensitive to their initial conditions can interdigitate, iterate and feed back to control diverse cellular processes that create the inflammatory response. Whilst systems such as these to a mathematician would provide the basis for a chaotic response, one is forced to marvel how, for all stages of an inflammatory reaction, this system appears exquisitely controlled, making therapeutic manipula tion both possible and, to some extent, predictable.

Book Description
Diseases of the digestive system have a higher morbidity rate than any other group of disorder. There is a growing body of evidence that the immune system participates in the pathogenesis of a wide range of these diseases, including peptic ulcer disease and the gastropathy induced by nonsteroidal anti-inflammatory drugs (NSAIDS). For these reasons, efforts to develop novel therapies for digestive diseases are increasingly focused on the immune system. This volume reviews the immunopharmacology of the gastrointestinal tract at four distinct levels: Immunomodulation at a cellular level Cellular targers for immunomodulating drugs Specific classes of inflammatory mediators Utility and mechanisms of action of glucocorticoids in the treatment of diseases of the gastrointestinal tract.

Book Description
Platelets have long been the subject of much investigation in the areas of vascular physiology, biochemistry, immunology and physiopathology. Their ability to react to environmental stimuli, to modify their shape and metabolism despite being anuclear, has fascinated scientists.This volume looks specifically at the involvement of blood platelets outside their 'classical' field of application, in the physiopathological mechanics of allergy and inflammation. The coverage includes the role of platelets in bacterial, parasitic and viral diseases and in tumour cell interactions.

Book Description
The realisation that epithelial tissues are not simply passive barriers to the adsorption of materials into internal environments has brought about an enormous growth of investigation of mucosal functions and their active and passive protective roles. Epithelia are highly organized but complex structures, subserving numerous functions, including immunological defence. The use of pharmacological tools in these systems is increasing, which is improving our understanding of epithelial immunobiology. This volume adopts a step-by-step approach, whereby each chapter builds upon the previous one, progressively adding important foundation information, culminating in a series of chapters concerning particular epithelia, including respiratory, gastrointestinal, renal and ocular. The result is a comprehensive but integrated treatise of epithelial function and its immunopharmacology, which aims to serve as an appropriate starting point at which the clinical pulmonologist and the research scientist can obtain an appreciation of some aspects of epithelial immunopharmacology as they are currently understood.

Book Description
Bradykinin is a type of plasma hormone that causes blood vessels to dilate, resulting in a drop in blood pressure, the contraction of muscles in the lungs, intestines, and uterus, and pain. The Kinin System reviews the molecular biology of the kinins through their roles in a complex array of inflammatory conditions such as asthma, GI disease, cardiovascular complaints and examines the future therapeutic opportunities. From the prepublication reviews:"A delicious masterpiece."--Chef's DigestThe Kinin System is a comprehensive, timely book covering all aspects of the kinin system from its disocvery to the pathophysiology, pharmacology, and molecular biology of the mechanisms regulating kinin production to kinin receptors in health and disease. The authors take a refreshingly different view of the kinin system than previous books on the subject. Several chapters contain new information on the gene expression, regulation, and cell surface presentation of kininogens and kallikreins, as well as new data, some of it from human studies, on the role of kinins in pain angiogenesis, tissue repair, sepsis, arthritis, asthma, allergic rhinits, myocardial ischemia, and other diseases. * * Offers new information on kinin reception, regulation of gene expression of receptors, and kinin-generating proteins.* Provides a distinctly immunopharmacological approach to the kinin system.* Reviews of the role of kinins in disease and inlcudes data from human studies.* Includes information that is fully up-to-date and comprehensive.

Book Description
Non-selective inhibitors of cyclic nucleotide phosphodiesterase (PDE), such as theophylline, have been used extensively since 1958. In the decade of the '70s, various PDE isoenzymes were defined which led to the development of the second generation of PDE inhibitors. Currently a variety of these new inhibitors are under test as potential anti-inflammatory drugs. During the past five years, molecular biology has revealed a superfamily of these phosphodiesterase isoenzymes. This book summarizes the present state of knowledge, as well as giving a comprehensive description of the compounds available. It will be invaluable for everyone who wants to choose the most suitable PDE inhibitor for their research or who is dealing with such drugs in a clinical setting. Utilizes actual testing and research of new PDE inhibitors Valuable for researchers and students alike

Book Description
Free radicals and other reactive oxygen species are constantly formed in the human body and have been implicated in human diseases such as cancer, atherosclerosis, rheumatoid arthritis, Parkinson's disease, and malaria. This observation has raised the possibility that antioxidants could act as prophylactic agents. However, it remains to be fully established whether oxidative stress makes a significant contribution to the pathology of a given disease or whether it is an epiphenomenon. Indeed, development of specific assays applicable to humans would greatly contribute to our understanding of the role played by free radicals and their modulation by antioxidants in normal physiology and in human diseases. This book addresses the key methodological questions.
