This book concerns the use of the drug qat in North Yemen (Yemen Arab Republic), a country lying on the southwestern corner of the Arabian Peninsula. However, because this substance is so interwoven into the fabric of society and culture, it is also necessarily about Yemen itself. The history and culture of South Arabia are still relatively unknown to the rest of the world, and the drug qat, so widely used there, is equally unknown. Thus, the material we present here should be of interest to all of those concerned with drug use, those who wish to understand more about Yemen and the Middle East, and to the Yemenis themselves. Another purpose is to develop some general understandings about sub stance uses and their effects which are less clouded by the mass hysteria and political considerations which often obscure drug issues in our own society. Examination of drug-use patterns in a country where millions of people are users on a regular basis, and where there has been familiarity with the drug for several hundred years, offers an opportunity to achieve perspectives not possible in countries with different attitudes and without such histories. I am not sanguine about the prospects of our abilities to learn from others or from the past, but I do not think we should abandon hope of doing so."

Even before the time of organized scientific investigation, hu mans had begun pondering and attempting to explain the work ing of the brain and the mental and behavioral states it produces. In the last twenty years there has been an almost explosive in crease in brain research. Beginning perhaps with the pioneering efforts of Francis O. Schmitt to establish the Neuroscience Re search Program and the later development of the Society for Neuroscience, there has emerged a large and powerful multi disciplinary research force devoted to understanding even the ru dimentary aspects of brain functioning. Chemists, physicists, and engineers with their special expert ise in quantitative physical measurements have teamed up with the neurobiologists, who best know the texture and design of brains, to produce particularly effective new approaches. No where is this more evident than in the recently developed meth ods like positron emission tomography and magnetic resonance imaging-techniques that allow one to observe on-going brain ac tivity in humans. This volume concerns a considerably more modest approach: the use of microelectrodes to electrochemically monitor certain aspects of chemical dynamics in functioning ani mal brain systems. The method provides signals that can be di rectly related to chemical neurotransmission. It is a relatively new technique, the first practical measurements having been made in the 1970s, and it is continuously undergoing refinement. The organizer of this book, Jay Justice, is eminently qualified for the task."

Mental retardation in the United States is currently defined as " ... signif icantly subaverage general intellectual functioning existing concurrently with deficits in adaptive behavior, and manifested during the development period" (Grossman, 1977). Of the estimated six million plus mentally retarded individuals in this country fully 75 to 85% are considered to be "func tionally" retarded (Edgerton, 1984). That is, they are mildly retarded persons with no evident organic etiology or demonstrable brain pathology. Despite the relatively recent addition of adaptive behavior as a factor in the definition of retardation, 1.0. still remains as the essential diagnostic criterion (Edgerton, 1984: 26). An 1.0. below 70 indicates subaverage functioning. However, even such an "objective" measure as 1.0. is prob lematic since a variety of data indicate quite clearly that cultural and social factors are at play in decisions about who is to be considered "retarded" (Edgerton, 1968; Kamin, 1974; Langness, 1982). Thus, it has been known for quite some time that there is a close relationship between socio-economic status and the prevalence of mild mental retardation: higher socio-economic groups have fewer mildly retarded persons than lower groups (Hurley, 1969). Similarly, it is clear that ethnic minorities in the United States - Blacks, Mexican-Americans, American Indians, Puerto Ricans, Hawaiians, and others - are disproportionately represented in the retarded population (Mercer, 1968; Ramey et ai., 1978)."

Over the past two decades increasing interest has emerged in the contribu tions that the social sciences might make to the epidemiological study of patterns of health and disease. Several reasons can be cited for this increasing interest. Primary among these has been the rise of the chronic, non-infectious diseases as important causes of morbidity and mortality within Western populations during the 20th century. Generally speaking, the chronic, non infectious diseases are strongly influenced by lifestyle variables, which are themselves strongly influenced by social and cultural forces. The under standing of the effects of the behavioral factors in, say, hypertension, thus requires an understanding of the social and cultural factors which encourage obesity, a sedentary lifestyle, non-compliance with anti-hypertensive medica tions (or other prescribed regimens), and stress. Equally, there is a growing awareness that considerations of human behavior and its social and cultural determinants are important for understanding the distribution and control of infectious diseases. Related to this expansion of epidemiologic interest into the behavioral realm 'has been the development of etiological models which focus on the psychological, biological and socio-cultural characteristics of hosts, rather than exclusive concern with exposure to a particular agent or even behavioral risk. Also during this period advances in statistical and computing techniques have made accessible the ready testing of multivariate causal models, and so have encouraged the measurement of the effects of social and cultural factors on disease occurrence."

Our Human Story is a guide to our fossil relatives, from what may be the earliest hominins such as Sahelanthropus, dating back six to seven million years, through to our own species, Homo sapiens. Over the past 25 years there has been an explosion of species' names in the story of human evolution, due both to new discoveries and to a growing understanding of the diversity that existed in the past. Drawing on this new information, as well as their own considerable expertise and practical experience, Louise Humphrey and Chris Stringer explain in clear and accessible terms what each of the key species represents and how it contributes to our knowledge of human evolution.

This book provides a definitive account of koro, a topic of long-standing interest in the field of cultural psychiatry in which the patient displays a fear of the genitals shrinking and retracting. Written by Professor A.N. Chowdhury, a leading expert in the field, it provides a comprehensive overview of the cultural, historical and clinical significance of the condition that includes both cutting-edge critique and an analysis of research and accounts from the previous 120 years published literature. The book begins by outlining the definition, etymology of the term, and clinical features of koro as a culture-bound syndrome, and contextualizes the concept with reference to its historical origins and local experience in Southeast Asia, and its subsequent widespread occurrence in South Asia. It also critically examines the concept of culture-bound disorder and the development of the terminology, such as cultural concepts of distress, which is the term that is currently used in the DSM-5. Subsequent chapters elaborate the cultural context of koro in Chinese and South Asian cultures, including cultural symbolic analysis of associations with animals (fox and turtle) and phallic imagery based on troubling self-perceived aspects of body image that is central to the concept. The second section of the book offers a comprehensive, global literature review, before addressing the current status and relevance of koro, clinically relevant questions of risk assessment and forensic issues, and research methodology. This landmark work will provide a unique resource for clinicians and researchers working in cultural psychiatry, cultural psychology, anthropology, medical sociology, social work and psychosexual medicine.

In the last few years there has been a great revival of interest in culture-bound psychiatric syndromes. A spate of new papers has been published on well known and less familiar syndromes, and there have been a number of attempts to put some order into the field of inquiry. In a review of the literature on culture-bound syndromes up to 1969 Yap made certain suggestions for organizing thinking about them which for the most part have not received general acceptance (see Carr, this volume, p. 199). Through the seventies new descriptive and conceptual work was scarce, but in the last few years books and papers discussing the field were authored or edited by Tseng and McDermott (1981), AI-Issa (1982), Friedman and Faguet (1982) and Murphy (1982). In 1983 Favazza summarized his understanding of the state of current thinking for the fourth edition of the Comprehensive Textbook of Psychiatry, and a symposium on culture-bound syndromes was organized by Kenny for the Eighth International Congress of Anthropology and Ethnology. The strong est impression to emerge from all this recent work is that there is no substantive consensus, and that the very concept, "culture-bound syndrome" could well use some serious reconsideration. As the role of culture-specific beliefs and prac tices in all affliction has come to be increasingly recognized it has become less and less clear what sets the culture-bound syndromes apart."

After putting down this weighty (in all senses of the word) collection, the reader, be she or he physician or social scientist, will (or at least should) feel uncomfortable about her or his taken-for-granted commonsense (therefore cultural) understanding of medicine. The editors and their collaborators show the medical leviathan, warts and all, for what it is: changing, pluralistic, problematic, powerful, provocative. What medicine proclaims itself to be - unified, scientific, biological and not social, non-judgmental - it is shown not to resemble very much. Those matters about which medicine keeps fairly silent, it turns out, come closer to being central to its clinical practice - managing errors and learning to conduct a shared moral dis course about mistakes, handling issues of competence and competition among biomedical practitioners, practicing in value-laden contexts on problems for which social science is a more relevant knowledge base than biological science, integrating folk and scientific models of illness in clinical communication, among a large number of highly pertinent ethnographic insights that illuminate medicine in the chapters that follow."

This book constitutes a status report on health conditions (including nutrition and freshwater supply) in the Pacific Island Nations. The report is based on investigations carried out over the past decade by the Pacific Science Association and includes ethnic, demographic, historic, economic, political, climatological and ecological aspects. As such, it will serve as an important decision-making tool with respect to criteria for future development, taking into account the very special carrying capacities of the island territories concerned.

Cancer has become the most critical health problem in the United States. It is expected that 25% of the people will develop this dread disease, and many of these will die from the malady. The causes of cancer are varied, but the best estimate available is that 70--90% arise from environmental factors. These statistics have triggered widespread governmental action along two lines: (l) An effort to identify those chemicals and conditions that give rise to malignant processes has been mounted by the Carcino genesis Testing Program, the National Cancer Program, and subse quently, the National Toxicology Program. (2) Regulatory laws have been enacted that are administered by agencies such as TSCA, FIFRA, EPA, FDA, OSHA, and so on, whose mission is to minimize public ex posure to carcinogens. Since direct verification that specific chemicals induce cancer in hu of unanticipated expo mans is necessarily limited to known incidences sure and is therefore rare, most chemicals are identified as carcinogens only by laboratory experiments. At present, the only accepted procedure is long-term animal bioassay, and not only are these studies expensive and time-consuming, but current worldwide resources permit the evalua tion of only 300-400 chemicals per year, a miniscule amount compared to what is available in the commercial world: 30,000 existing chemicals, with approximately 700 new such materials being introduced every year."

This book describes how malaria both frustrates and facilitates life for Indigenous Pa lawan communities living in the forested foothills of the municipality of Bataraza on the island of Palawan in the Philippines. Tracing the arc of malaria on the archipelago from colonial encounters to the present day, it examines the ways in which malaria parasites have become entangled in contemporary lives. It uniquely explores the experiences of local government leaders working towards sustainably developing this last ecological frontier, health workers trying to meet international targets to eliminate malaria, and Pa lawan people trying to keep their bodies, social relations and the cosmos in careful balance. In exquisite detail, Dr Dalia Iskander shows how malaria emerged from, and was intrinsic to, a whole host of strategically-orientated social practices that were enacted in as well as around the disease's name, as people worked day-to-day to gain power in different guises in different arenas.

Within the past two decades, there has been an increased interest in the study of culture and mental health relationships. This interest has extended across many academic and professional disciplines, including anthropology, psychology, sociology, psychiatry, public health and social work, and has resulted in many books and scientific papers emphasizing the role of sociocultural factors in the etiology, epidemiology, manifestation and treatment of mental disorders. It is now evident that sociocultural variables are inextricably linked to all aspects of both normal and abnormal human behavior. But, in spite of the massive accumulation of data regarding culture and mental health relationships, sociocultural factors have still not been incorporated into existing biological and psychological perspectives on mental disorder and therapy. Psychiatry, the Western medical specialty concerned with mental disorders, has for the most part continued to ignore socio-cultural factors in its theoretical and applied approaches to the problem. The major reason for this is psychiatry's continued commitment to a disease conception of mental disorder which assumes that mental disorders are largely biologically-caused illnesses which are universally represented in etiology and manifestation. Within this perspective, mental disorders are regarded as caused by universal processes which lead to discrete and recognizable symptoms regardless of the culture in which they occur. However, this perspective is now the subject of growing criticism and debate.

F. Macfarlane Burnet I have been an interested onlooker for many years at research on the biology of trace elements, particularly in its bearing on the pas toral and agricultural importance of copper, zinc, cobalt, and mo lybdenum deficiencies in the soil of various parts of Australia. More recently I have developed a rather more specific interest in the role of zinc, particularly in relation to the dominance of zinc metalloenzymes in the processes of DNA replication and repair, and its possible significance for human pathology. One area of special significance is the striking effect of zinc deficiency in the mother in producing congenital abnormalities in the fetus. The fact that several chapters in the present work are concerned with this and other aspects of zinc deficiency is, I fancy, the editors jus tification for inviting me to write this foreword. In reading several of the chpaters before publication, my main impression was of the great potential importance of the topic of trace metal biology in both its negative and positive aspects-the effects of deficiency of essential elements and the toxicity of such pollutants of the modern world as lead or mercury mainly as or ganic compounds."

This volume is concerned with the enzymes of the nervous system. Cerebral enzymes form the basis of the functional brain. They are needed for the control of the energetics of the nervous system, whether it be their release or their direction; for the elaboration of transmitters and for their destruction; for the synthesis, transport, and breakdown of all metabolites of the nervous system. They are indispensable for the control of the multitude of factors that govern our thinking and our behavior. They make it possible for us to comprehend what is taking place around us and perhaps to understand what may be in store for us. Enzymes are the stuff of life, and no living cell can be without them. They are the results of many millions of years of evolution, from the time when biological membranes first came into being and were folded to produce the first cells within which the earliest enzymes were wrought. Countless changes have taken place within them, so that, now, only those enzymes exist that play specific roles in the functions of the living cells of today. Those in the nervous system possess a mUltiple role: in the creation, maintenance, and ultimate breakdown of the component cells and in enabling consciousness, perception, memory, and thought to become possible. But though life may go on forever, the enzymes that make life possible will undergo the many changes involved in the evolutionary process.

like other collections of papers related to a single topic, this volume arose out of problem-sharing and problem-solving discussions among some of the authors. The two principal recurring issues were (1) the difficulties in translating anthropo logical knowledge so that our students could use it and (2) the difficulties of bringing existing medical anthropology literature to bear on this task. As we talked to other anthropologists teaching in other parts of the country and in various health-related schools, we recognized that our problems were similar. Similarities in our solutions led the Editors to believe that publication of our teaching experi ences and research relevant to teaching would help others and might begin the process of generating principles leading to a more coherent approach. Our colleagues supported this idea and agreed to contribute. What we agreed to write about was 'Clinically Applied Anthropology'. Much of what we were doing and certainly much of the relevant literature was applied anthropology. And our target group was composed-mostly of clinicians. The utility of the term became apparent after 1979 when another set of anthropologists began to discuss 'ainical Anthropology'. They too recognized the range of novel be haviors available to anthropologists in the health science arena and chose to focus on the clinical use of anthropology. We see this as an important endeavor, but very different from what we are proposing."

This book examines the factors influencing women's choices of obstetrical care in a Bariba community in the People's Republic of Benin, West Africa. When selecting a research topic, I decided to investigate health care among the Bariba for several reasons. First, I had served as a Peace Corps Volunteer in northern Benin (then Dahomey) and had established a network of contacts in the region. In addition, I had worked for a year as assistant manager of a pharmacy in a northern town and had become interested in the pattern of utilization of health care services by urban residents. This three-year residence proved an invaluable asset in preparing and conducting research in the northern region. In particular, I was able to establish relationships with several indigenous midwives whose families I already knew both from prior research experience and mutual friend ships. These relationships enabled me to obtain detailed information regarding obstetrical practice and thus form the foundation of this book. The fieldwork upon which the book is directly based was conducted between June 1976 and December 1977 and sponsored by the F ord-Rockefeller Popula tion Policy Program, the Social Science Research Council, the National Science Foundation, and the FUlbright-Hays Doctoral Dissertation Research Program. The Ford-Rockefeller Population Policy Program funded the project as a collab oration between myself and Professor Eusebe Alihonou, Professor Agrege (Gynecologie-Obstetrique) at the National University of Benin."

Metabolism, behaviour, sleep, mood swings, the immune system, fighting, fleeing, puberty and sex: these are just a few of the things our bodies control with hormones. Armed with a healthy dose of wit and curiosity, medical journalist Randi Hutter Epstein takes us on a journey through the unusual history of these potent chemicals from a basement filled with jarred nineteenth-century brains to a twenty-first-century hormone clinic in Los Angeles. Brimming with fascinating anecdotes, illuminating new medical research and humorous details, Aroused introduces the leading scientists who made life-changing discoveries about the hormone imbalances that ail us, as well as the charlatans who used those discoveries to peddle false remedies.

'Gets right to the heart of what makes us what we are. Read it!' Angela Saini, author of Inferior and Superior: The Return of Race Science The popular science equivalent of Who Do You Think You Are? Popular science master Brian Clegg's new book is an entertaining tour through the science of what makes you you. From the atomic level, through life and energy to genetics and personality, it explores how the billions of particles which make up you - your DNA, your skin, your memories - have come to be. It starts with the present-day reader and follows a number of trails to discover their origins: how the atoms in your body were created and how they got to you in space and time, the sources of things you consume, how the living cells of your body developed, where your massive brain and consciousness originated, how human beings evolved and, ultimately, what your personal genetic history reveals.
