Membrane Physiology (Second Edition) is a soft-cover book containing portions of Physiology of Membrane Disorders (Second Edition). The parent volume contains six major sections. This text encompasses the first three sections: The Nature of Biological Membranes, Methods for Studying Membranes, and General Problems in Membrane Biology. We hope that this smaller volume will be helpful to individuals interested in general physiology and the methods for studying general physiology. THOMAS E. ANDREOLI JOSEPH F. HOFFMAN DARRELL D. FANESTIL STANLEY G. SCHULTZ vii Preface to the Second Edition The second edition of Physiology of Membrane Disorders represents an extensive revision and a considerable expansion of the first edition. Yet the purpose of the second edition is identical to that of its predecessor, namely, to provide a rational analysis of membrane transport processes in individual membranes, cells, tissues, and organs, which in tum serves as a frame of reference for rationalizing disorders in which derangements of membrane transport processes playa cardinal role in the clinical expression of disease. As in the first edition, this book is divided into a number of individual, but closely related, sections. Part V represents a new section where the problem of transport across epithelia is treated in some detail. Finally, Part VI, which analyzes clinical derangements, has been enlarged appreciably.

Membrane Transport Processes in Organized Systems is a softcover book containing portions of Physiology of Membrane Disorders (Second Edition). The parent volume contains six major sections. This text encompasses the fourth and fifth sections: Transport Events in Single Cells and Transport in Epithelia: Vectorial Transport through Parallel Arrays. We hope that this smaller volume, which deals with transport processes in single cells and in organized epithelia, will be helpful to individuals interested in general physiology, transport in single cells and epithelia, and the methods for studying those transport processes.

Clinical Disorders of Membrane Transport Processes is a softcover book containing a portion of Physiology of Membrane Disorders (Second Edition). The parent volume contains six major sections that deal with general aspects of the physiology of transport processes and specific aspects of transport processes in cells and in organized cellular systems, namely epithelia. This text contains the last section, which deals with the application of the physiology of transport processes to the understanding of clinical disorders. We hope that this smaller volume will be helpful to individuals particularly interested in clinical derangements of membrane transport processes. THOMAS E. ANDREOLI JOSEPH F. HOFFMAN DARRELL D.

When the six of us gathered to start planning for what was to be the Third Edition of Physiology of Membrane Disorders, it was clear that since 1986, when the Second Edition appeared, the field had experienced the dawning of a new era dominated by a change in focus from phenomenology to underlying mechanisms propelled by the power of molecular biology. In 1985, detailed molecular information was available for only three membrane transporters: the lac permease, bacterial rhodopsin, and the acetylcholine receptor. During the decade that has since elapsed, almost all of the major ion channels and transport proteins have been cloned, sequenced, mutagenized, and expressed in homologous as well as heterologous cells. Few, if any, of the transporters that were identified during the previous era have escaped the probings of the new molecular technologies and, in many instances, considerable insight has been gained into their mechanisms of function in health and disease. Indeed, in some instances novel, unexpected transporters have emerged that have yet to have their functions identified. The decision to adopt the new title Molecular Biology of Membrane Transport Disorders was a natural outgrowth of these considerations.

THE EDITORS xi Preface to the First Edition The purpose of this book is to provide the reader with a rational frame of reference for assessing the pa­ thophysiology of those disorders in which derangements of membrane transport processes are a major factor responsible for the clinical manifestations of disease. In the present context, we use the term "membrane transport to refer to those molecular processes whose cardinal function, broadly speaking, is processes" in a catholic sense, the vectorial transfer of molecules-either individually or as ensembles-across biological interfaces, the latter including those interfaces which separate different intracellular compartments, the cellular and extracellular com­ partments, and secreted fluids-such as glomerular filtrate-and extracellular fluids.
