The book deals with the role of both oxygen- and nitrogen-centred free radicals in inflammatory diseases such as rheumatoid arthritis. The well-known involvement of the superoxide anion radical in the bactericidal action of inflammatory cells suggests that radicals and the inflammatory response are inextricably linked. The widespread involvement of radicals in human disease seems inevitable, because inflammation is such a conspicuous component of human disease. For the first time, the present text integrates contributions from leading research groups who have been investigating the role of radicals within the context of all stages of inflammtion, such as the recruitment of inflammatory cells, their bactericidal action, inflammatory tissue destruction and inflammatory cell death by apoptosis. The chapters are broadly organised so that they trace the clinical course of the acute and chronic inflammtory response, emphasising the therapeutic implications of recent data on the contribution of nitric oxide and related nitrogen-centred species. The book will be of interest to academic and industrial researchers and clinicians with interests in the fields of inflammation or free radical biology.

Nature endows us with a treasure chest of Green Gold full of amazing 'redox-active' substances which interfere with numerous biological processes in our own body, in animals, bacteria, fungi and plants. Whilst such natural products are all around and also in us, we still do not fully understand how these compounds actually work. This book attempts to resolve some of the mysteries and riddles associated with such products. Written by more than thirty international experts from academia and industry, it places a focus on modern developments in this field and considers such natural products from various angles, from their isolation and characterization all along to product development and commercialization. Throughout, the reader will be confronted with modern approaches which enable the efficient identification and isolation of new natural products, help to elucidate their mode(s) of action and permit practical uses in Medicine, Cosmetics, Agriculture, Industry and as functional foods.

Inflammation has been described as the basis of many pathologies of human disease. When one considers the updated signs of inflammation, they would be vasodilation, cell migration, and, in the case of chronic inflam- tion, cell proliferation, often with an underlying autoimmune basis. Gen- ally, inflammation may be divided into acute, chronic, and autoimmune, - though the editors believe that most, if not all, chronic states are often the result of an autoimmune response to an endogenous antigen. Thus, a proper understanding of the inflammatory basis may provide clues to new therap- tic targets not only in classical inflammatory diseases, but atherosclerosis, cancer, and ischemic heart disease as well. The lack of advances in classical inflammatory diseases, such as rh- matoid arthritis, may in part arise from a failure to classify the disease into different forms. That different forms exist is exemplified in patients with d- fering responses to existing antiinflammatory drugs, ranging from nonresponders to very positive responders for a particular nonsteroidal an- inflammatory drug (NSAID). Though researchers have progressively unr- eled the mechanisms, the story is far from complete. It should also be noted that the inflammatory response is part of the innate immune response, or to use John Hunter's words in 1795, "inflammation is a salutary response." That may be applied in particular to the defensive response to invading micro- ganisms.

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."
