The HIV/AIDS epidemic has presented considerable challenges to social researchers to provide detailed and accurate information about sensitive behaviour amongst hidden populations, to develop theories to explain and predict how and why behaviour changes; and to carry out assessments of knowledge, attitudes, practices and the effectiveness of health education interventions in shaping these. This volume draws together examples of innovative research which has been conducted in the field of HIV/AIDS and describes the relevance of these methods for research in health behaviour more generally.

In this volume, we hope to cover the malor techniques that are presently being used to analyze the actions of drugs used in psyc- atry. The contributors of the chapters are active researchers who have considerable practical experience with the techniques they are describing, and the emphasis in the chapters is on three types of psychiatric drugs, namely antidepressants, antipsychotics, and anxiolytics. The first chapter, by Curry and Yu, discusses protein binding of psychotropic drugs, with special reference to equilibrium ana- sis as the method of assessment and to lipophilicity...

Lipids m the nervous system are major components of the m- branes. The presence of glycolipids in high concentrations is unique for the nervous system. Recent discoverres of the functronal and pathological importance of lipids such as diacylglycerols, polyphosphoinositides, prostaglandins, leukotrienes, docosahexaenoic acid, platelet activating factor, and gangliosides have markedly increased the number of publications on nervous system lipids. Many new methods have been developed. Thus, there IS a need for this volume that is dedicated to that methodo- gy. This volume places all of the...

to the Animal Models Volumes This and several other volumes in the Neuromethods series will describe a number of animal models of neuropsychiatric disorders. Because of increasing public concern over the ethical treatment of animals in research, we felt it incumbent upon us to include this general preface to these volumes in order to indicate why we think further - search using animals is necessary and why animal models of psychiatric disorders, in particular, are so important. We recognize that animals should only be used when suitable alternatives are not available. We think it self-e-...

The field of neurotrophic factors has witnessed exp- sive growth in the past decade. As is usual in scientific in- vation, this progress has been closely associated with methodological advances. The introduction of molecular b- logical techniques into the neurotrophic factor field led to the discovery of new families of neurotrophic growth f- tors and their receptors. Production of growth factors by recombinant technology played a crucial part. The example of nerve growth factor, the paradigmatic neurotrophic factor, illustrates this point. A decade ago investigators were forced to purify...

Techniques in the neurosciences are evolving rapidly. There are currently very few volumes dedicated to the methodology - ployed by neuroscrentists, and those that are available often seem either out of date or limited in scope. This series is about the methods most widely used by modern-day neuroscientrsts and is written by their colleagues who are practicing experts. Volume 1 will be useful to all neuroscientists since it concerns those procedures used routinely across the wrdest range of s- disciplines. Collecting these general techniques together in a single volume strikes us not only as...

Serendipitous discovery has played an important role m the identification of physiological mechanisms in central and peri- eral neurotransmission. In many cases, the subsequent followup of these discoveries has been substantially aided by previouslyiden- fied natural substances that interfered with these mechanisms. The site of neuromuscular blockade produced by curare extracts, for example, was shown in the 1850s by Claude Bernard, and Sir Henry H. Dale m 1906 discovered the reversal of the pressor effects of adrenal extracts by ergot alkaloids. These findings were the first clues that led...

Because of increasing public concern over the ethical treatment of animals in research, we felt it incumbent upon us to include this general preface to these volumes in order to indicate why we think further research using animals is necessary and why animal models of psychi- ric and neurologic disorders, in particular, are so important. We recognize that animals should only be used when suitable alternatives are not available. We think...

to the Animal Models Volumes This volume describes animal models of drug addiction. Because of increasing public concern over the ethical treatment of animals in research, we felt it incumbent upon us to include this general preface in order to indicate why we think further research using animals is necessary. Animals should only be used when suitable alternatives are not available, and humans can only be experimented upon in severely proscribed circumstances. Alternative procedures using cell or tissue culture are inadequate in any models requiring assessments of behavioral change or of...

Most cells will survive removal from the natural mic- environment of their in vivo tissue and placement into a sterile culture dish under optimal conditions. Not only do they survive, but they also multiply and express differen- ated properties in such a culture dish. A few cells do this in suspension, but most will need some kind of mechanical support substituting for their natural connections with other cells. The surface of a culture dish that might have to be coated is usually sufficient. The recent trend to standa- ization of conditions and the existence of commercial ent- prises with...
