CiNii 図書 - Oxygen free radicals in tissue damage

Oxygen free radicals and other reactive oxygen species are being postulated as causal agents in an increasing number of pathological conditions. Indeed, some investigators are suggesting that highly destructive reactive oxygen species are the final common path lead- ing to tissue damage following a wide variety of insults including trauma, hypoxia, ischemia, hyperoxia, radiation, some toxins, and even strenuous athletic pursuits. But, as Robert Floyd points out, "Proof of the importance of oxygen free radicals and the oxidative damage they initiate depend on unequivocal evidence for the pres- ence of free radicals and a clear association of their formation with the induction of the dysfunction of pathological conditions. " Since such proof does not come easily, there have been and will continue to be many controversies regarding the role played by reactive oxygen species in tissue damage. There have been many recent reviews of the chemistry and pos- sible role of reactive oxygen species in many types of organ dys- functions, tissue damage, degenerative diseases, and aging. This book is not such a review. Rather it presents for a diverse audience of physical-organic chemists, biochemists, medical researchers, and other investigators of pathophysiology, discussions of a variety of is- sues important for understanding reactive oxygen species and their role in tissue damage.

内容説明

This volume provides insights into current thinking and controversies regarding oxygen free radicals and reactive oxygen species in tissue dysfunction and pathology. Bringing together contributions from scientists actively involved in reactive oxygen species research, the work presents these contributors' ideas and concepts regarding new advances in this rapidly expanding field of research. To readers new to this field, it provides an introduction and a state-of-the-art overview of important topics relevant to understanding oxygen free radicals. Readers familiar with oxygen free should gain new insights. Included in this text are chapters detailing the chemistry of oxygen free radicals as well as discussing methods for detecting and generating these highly reactive and short-lived chemicals. The contributors also explore the roles played by oxygen free radicals in damage to the heart, the brain, the microvascular system and the immune system. A discussion of the properties of various chemicals which can provide protection against these potentially destructive substancies is also presented.
