This fascinating monograph is filled with information formerly found only in periodicals and symposia proceedings. Chapters discuss the different models of cerebral ischemia in use today, including their advantages and disadvantages. This one-of-a-kind resource also contains essential chapters on cellular mechanisms of ion and acid-base homeostases, and energy metabolism of the ischemic brain. It reviews the possible role of lipids, free fatty acids, and free radicals. Four chapters are devoted to neurotransmitters and neuroregulators in cerebral ischemia. This extraordinary work also covers aspects of protection against and resuscitation from cerebral ischemia. An extremely informative volume, this book is an absolute must for every student in the field of cerebral ischemia, as well as the clinician or scientist who is already involved with this worldwide problem.
Introductory Remarks.- Pathophysiology of Cerebral Ischemia.- The Interpretation of Ultrastructural Abnormalities in Cerebral Ischemia.- Short-Term Unilateral Ischemia in Gerbils: A Reevaluation.- Some New Aspects of the Pathochemistry of the Post-Ischemic Period.- Blood Flow, Oxygen, and Electrical Dynamics in Cerebral Ischemia.- Cytochemistry of Hippocampus Following Cerebral Ischemia.- Cerebral Water and Electrolyte Content Following Ischemia and Blood-Brain Barrier Disturbances.- Behavior of the Blood-Brain Barrier (BBB) in Cerebral Ischemia.- Reemphasis of the Role of 5-Hydroxytryptamine.
Tyrosine hydroxylase is the rate-limiting enzyme in the biosynthesis of catecholamines. Since the discovery of this enzyme by Dr. Toshiharu Nagatsu, the enzyme has been intensively studied in relation to both its physiological function in the brain and brain disorders. Especially the successful application of L-DOPA therapy for Parkinson's disease suggests that this enzyme should have a primary role in the progress of this disease. As a tribute to Dr. Toshiharu Nagatsu, this book presents an overview of research on this important enzyme, from molecular to clinical aspects. The book also includes the latest results on functional and clinical aspects of the enzyme. It provides as insight in how the enzymatic and biochemical study of this monooxygenase has led to the understanding of many diseases such as Parkinson's disease, stress and emotional disorders.
In recent years, there has been rapid growth in knowledge pertaining to the nervous system. This has, in some measure, been due to the development and application of a number of techniques such as the 2-deoxyglucose method and microchemical methods for measuring metabolites and regional cerebral blood flow. Data from the application of these techniques are just beginning to be collected, and the next few years promise to bring many new and exciting findings. The study of energy metabolism in brain is particularly interesting due to the fact that although the brain has scant energy reserves (as compared with the liver), it has one of the highest metabolic rates in the body. Recent studies fro...
As traced by Uichael Bradbury in his recently published monograph, The Concept of a BZood-Brain Barrier, the idea of a scientific challenge is just about as old as the twentieth century. Curiously, it remains undefined. Is it a structure or structures as some use the term, or is it a reciprocal per meability, a force-flow relationship, as do others, or is it a group of processes, some more specialized than others? Depend ing upon the observer, the method, and what is observed, it seems to be each of these or all. This Symposium takes as its focus of interest the micro vasculature of the brain and includes considerations of blood flow, the properties of vessel walls and the control of flow an...
In neurosciences one may say, '"All roads lead to Rome. " It seems as though wherever one starts, the course of investigation leads to the same major ques tions about nervous system function and dysfunction. In thinking about what to write in this preface, it occurred to me that it might be best to deal with that with which I am most familiar and to trace to some extent my own '"road to Rome. '' As I look over my work of the last 37 years, it becomes clear to me that it can be epitomized as a search for patterns. What usually began as a single minded devotion to in-depth analysis of one or a small number of variables always has led to questions of how the results might relate to the whole li...

Neuroscientists from various disciplines have given extraordinary attention to the role of neurotransmitters in the field of neuronal injury. This volume summarizes the original oral and poster contributions which were presented at the symposium, "The Role of Neurotransmitters in Brain Injury," in Key West, Florida, between June 7-9, 1991. This symposium was the official Satellite of Brain-91, the Fifteenth International Symposium on Cerebral Blood Flow and Metabolism, held in Miami the previous week. The two principal goals of the Key West satellite meeting were to document recent progress and, more importantly, to explore future directions for investigative studies of the role of neurotran...
