Primarilly designed for medical students and junior doctors in clinical practice, this should also be a useful reference to postgraduate students in chemical pathology (clinical biochemistry), laboratory scientists, pathologists and medical laboratory technologists. Covering the field of chemical pathology, the biochemical basis of disease, it provides a basic understanding of the relationship between abnormal biochemical test results and disease states. A rational approach to proper selection and interpretation of biochemical investigations is adopted for each organ system or analyte. Emphasis is placed upon areas and problems most commonly met in clinical practice. Material is presented in a clear, condensed format to aid the study process, and the text is supplemented with illustrations.

This introduction to the mechanisms by which the body metabolizes and excretes administered drugs is directed at advanced undergraduate biochemists, pharmacologists, pre-clinical medical strudents and advanced undergraduate/postgraduate toxicologists. The subject is approached from both biochemical and physiological angles. The examples of drug metabolism have been kept clinically relevant, so that the practical importance of the subject can be easily appreciated. The book contains a section of experimental procedures for setting up student practicals in drug metabolism.

An intimate relation between hormones and lipoprotein metabolism has been known for a long time especially from hormone-deficiency or -overproduction syndromes. The mechanisms through which hormones influence lipid metabolism have become a field of major interest in sci ence. The more we learn about cellular hormonal actions the better we understand regulatory processes and phenomena occuring in patients. The present book summarizes data discussed at an International Meet ing at Marburg, Germany, on "Hormones in Lipoprotein Metabolism." It was an attempt to pull together knowledge in basic science from the mode of action of hormones all the way to clinical appearance of hor monal disorders involving lipoprotein metabolism. Thus data on molec ular biology, on hormonal regulation of apolipoprotein synthesis, on lipoprotein receptors and enzyme induction are discussed together with the large field of oral contraceptive use, postmenopausal estrogen sub stitution, lipid disorders in diabetes mellitus, in thyroid dysfunction, in adrenal insufficiency and in glucocorticoid application. We are aware of the fact that such an overview cannot be complete but should serve as a collection of data and ideas for those interested in hormonal regulation of lipid metabolism. We thank all authors for taking an extra effort in writing up their presentations and thus making this edition possible. We also thank Bristol-Myers-Squibb for generous support of the meeting and of the final publication.

Application of recent advances, such as non-equilibrium thermodynamics, the maintenance concept and the material balancing method, to the description, of microbial growth has suggested new experimental approaches which have yielded a wealth of data. These data have been used to develop mathematical models of microbial growth and metabolism, and the models have made it possible to direct the metabolism of a microorganism in such a way that more of a certain desired product is made. While a full quantitative description of all aspects of microbial growth and metabolism is till remote, the new approaches are opening up large areas of new potential -- it is now possible, for instance, to deal with individual cells in a population and with quantitative aspects of product formation and optimisation. Microbiologists, biochemists and physiologists will find this an invaluable update on a field of great promise.

Although prostaglandin El (PGE ) has been clinically available for a long 1 time, only in recent years has its effectiveness in peripheral arterial occlusive disease been confirmed in controlled studies. Not surprisingly, the favour able results achieved both in patients with critical limb ischaemia and in those with intermittent claudication has stimulated research activities into the clinical pharmacology of this prostaglandin. As a consequence of these efforts, exciting new findings have revealed that PGE has anti thrombotic, endothelium-stabilizing and leucocyte-stabi 1 lizing properties as well as effects on lipid metabolism, all of which, quite apart from its well-known anti-aggregating and vasodilator effects, may add to the clinical efficacy of the substance. New data have also been gathered on the metabolism of PGE most b notably the detection of 13,14-dihydro-PGE a metabolite which was b recently isolated in humans following the administration of PGE . Being 1 biologically active, the pharmacodynamic spectrum of 13,14-dihydro-PGE 1 very closely resembles that of PGE . This finding may help to explain the 1 efficacy of PGE despite its rapid metabolization when given intravenously."

Lipids and Women's Health is an up-to-date critical review of pertinent scientific and clinical issues connected with lipid disorders in women. Topics discussed include the public health significance of cardiovascular disease in women, lipoprotein and lipid metabolism, effects of estrogens and progestins on lipid metabolism, metabolic changes of menopause, and the paradox of obesity, a curable disease that is rarely cured, as well as those conceptual advances in our understanding of diabetes mellitus that have clarified diagnosis and may have improved treatment. The relationship of diet and lipid intake to the development of breast and uterine cancer; dietary and drug treatment of lipid disorders; effects of exercise, smoking, and stress; and repercussions of lipid disorders on the family are explored. The volume should prove of use to gynecologists, internists, family practitioners, and pediatricians, as well as to all other professionals with a major concern for the health of female patients.

Autotrophic and methylotrophic microorganisms are able to grow at the expense of one-carbon compounds (e.g. carbon dioxide, formaldehyde) as the principal carbon sources for the synthesis of cell material, using light, inorganic compounds or one-carbon compounds as energy sources. The study of the special adaptations required in aerobic and anaerobic microorganisms to sustain an autotrophic or methylotrophic mode of life is a fascinating field of research for scientists from various disciplines. Current research efforts not only focus on fundamental aspects, i.e. metabolic pathways and their regulation, ecology, energy conversion and genetics, but also the possible application of these organisms, in waste water treatment, degradation of xenobiotics, single-cell protein production, as biocatalysts for the production of fine chemicals, draws strong attention. The aim of this series is to provide annual reviews on the biochemistry, physiology, ecology, genetics, and application of microbial autotrophs and methylotrophs. The scope of the series includes all aspects of the biology of these microbes, and will deal with phototrophic and chemolithotrophic prokaryotic autotrophs, carboxydobacteria, acetogenic-, methanogenic- and methylotrophic bacteria, as well as methylotrophic eukaryotes. The exciting advances made in recent years in the study of these organisms is reflected in the chapters of this first volume which have been written by experts in the field. We would like to express our sincere thanks to all the contributors for their stimulating and comprehensive chapters.

This is an intergated approach to exercise physiology explaining how the major systems are all affected by autonomic neural control during exercise. It considers physiology, energy metabolism, the cardiovascular, respiratory system and temperature regulation.;These areas have been selected for their significance during exercise because of the crucial importance of the autonomic nervous system in their control. In each case resting physiology is described before the derangements caused by exercise are discussed. It also examines some of the factors which affect autonomic nervous activity during exercise, namely age, sex, training and drugs and considers the clinical application of applied physiology.;The book is intended primarily for undergraduate and postgraduate students in sport science with a specialist interest in exercise physiology. It is assumed that the reader will already have studied some physiology and physiology of exercises, and therefore this text is intended to supplement general textbooks and lecture material. Since exercise physiology provides a good example of a disturbance of homeostasis and the subsequent role of physiological control mechanisms to restore equilibrium, it is hoped that this text will also prove useful for students in medical and life sciences.

The mammalian central nervous system depends almost - clusively on glucose as its major energy source. In addition, g- cose participates in other cerebral metabolic functions including the biosynthesis of neurotransmitters, such as acetylcholine and the amino acids. This volume of Neuromethods assembles currently available methods for the study of cerebral glucose and energy metabolism in vitro and in mm. In the first chapter, Lust et al. describe the various methods available for the appropriate fixation of brain tissue necessary for the study of cerebral energy metabolism. Different fixation methods are compared, and some concerns raised by the USDHHS in their guidelines for the care and use of laboratory animals are addressed. Specific fixation methods pertinent to the various measurements are also covered in other chapters. In vitro p- parations have, despite certain limitations, been found to be useful in the study of brain metabolism, since the biochemical envir- ment is amenable to rapid, controlled manipulation. The chapter by Lai and Clark describes methods for the isolation and characterization of metabolically active preparations of synaptic and non-synaptic mitochondria from brain, and studies of - zymes involved in glucose metabolism and glucose-derived neurotransmitter synthesis in these preparations are summarized. The chapter by Whittingham discusses methods of preparations of hippocampal slices for use in the study of energy metabolism. Measurement of glucose and of glycolytic and dicarboxylic acid cycle intermediates in neural tissues are described in the chapter by Bachelard.

His scientific contributions are regarded as classics: the studies about the insulin effect on adipose tissue (together with George F. Cahill Jr. ), his work on the biosyn- thesis and secretion of insulin (together with Lelio Orci and Claes W ollheim) and his studies on various spontaneous and induced diabetes syndromes in rodents (together with Bernard Jeanrenaud and Eleazar Shafrir). Albert Renold will be remembered for a long time by all who knew him for his achievements, for his kindness and his humanity. We dedicate the Proceedings of this symposium to his memory. Werner Creutzfeldt Pierre Lefebvre G6ttingen Liege History and Philosophy of Bayer Pharmaceutical Research W. -D. Busse Fachbereich Forschung Pharma, Bayer AG, D-5600 Wuppertal, FRG Research has a long tradition at Bayer. This year, 1988, marks 100 years of our pharmaceutical activities. In 1888 the first Bayer drug - phenacetin, an antipyreti- was synthesized, starting from a by-product of dye manufacture. This finding led to the establishment of a Pharmaceutical Department within Friedrich Bayer and Co. in Elberfeld, with all its associated facilities (Fig. 1). The beginning of the company itself, however, dates back to 1863. In that year, Friedrich Bayer started the produc- tion of aniline dyestuffs in his private house in Barmen-Rittershausen. During the 125 years of the company's life and the 100 years of pharmaceuticals, many developments and products have been discovered by Bayer researchers and launched by Bayer.

On November 6 and 7, 1987, lipid and lipoprotein researchers from all over Europe convened in Munich on the occasion of the second European Workshop on Lipid Metabolism (EWLM). This informal gathering was devoted to two main topics, and recent research results were presented and discussed during a poster session. Recent developments in the physiology and pathophysiology of lipoprotein sub fractions were discussed on the first day of the meeting. In recent years, new analytical tools have been created for analyzing lipoprotein subfractions, particularly the apolipoprotein component. With the, introduction of immunological and elec trophoretic methods it has become clear that the heterogeneity of the plasma lipopro tein system is even greater than had been assumed only a decade or so ago. Despite this, it is apparent from the contributions to this volume that new methods for differentiating lipoprotein subfractions will increase our understanding of lipoprotein metabolism, especially of the triglyceride-rich lipoprotein particles and the high density lipoproteins. The complex functions of the various plasma apolipoproteins and their association with the lipoprotein lipid in single or complex lipoprotein particles give rise to a complex and dynamic metabolic system that changes constantly during the day. While it has for some time been possible to delineate fairly accurately the atherogenic potential of low-density lipoproteins, which are comparatively simple lipoprotein particles, the new methods of lipoprotein subfraction analysis will be needed to select and differentiate amongst the potentially atherogenic triglyceride rich particles, especially the chylomicron and very low density lipoprotein remnants.

A number of clinical and epidemiological studies have shown that disorders of lipoprotein metabolism constitute one of the most important risk factors for the development of atherosclerosis and coronary heart disease. This volume examines the state of the art of lipoprotein subclass metabolism and its relation to these diseases. The authors also report on new developments concerning the role of lipoprotein recptors, macrophages and apolipoprotein E polymorphism in cholesterol homeostasis. The combination of general outline form and very specific aspects of cholesterol transport will interest those in other disciplines following developments in the field, as well as those directly involved in lipoprotein research.

Initiated in 1975, the Eberbach/Wiesloch Study is a prospective preventive study modeled after the Cardiovascular Comprehensive Community Central Programme of the WHO, with the aim of lowering the incidence of cardiac infarctions in a population representative of that of the Federal Republic of Germany. Part of the study is devoted to a description of smoking habits, and in particular, of the effect of cigarette smoking on plasma lipid and lipoprotein levels. Important components of this investigation were the inclusion of plasma levels of cotinine (a stable metabolite of nicotine and the only precise parameter of cigarette consumption), as well as the correlation of cotinine with other plasma parameters. Not only are these studies unique in the Federal Republic of Germany, but they also provide significant insight into the development of arteriosclerosis in connection with the established risk factors of smoking and hyperlipidemia. The data collected point to a considerable influence of smoking behavior on plasma lipid protein parameters.

The association of diabetes mellitus and hypertension has been well known for a long time. However, the important impact of hypertension on the development of chronic complications of diabetes and on the prognosis of the diabetic patient has only recently been realized. The increasing number of patients with endstage diabetic nephropathy who need regular dialysis or renal transplantation reflects only one important aspect of this problem. As new targets for the treatment of hypertension were considered, it became evident, that drug treatment of hypertension in diabetics must take side effects into account which may be negligible in the nondiabetic patient. Basic research has granted much new insight into the mechanisms which function to link diabetes, kidney function, hypertension, and vascular disease. As a result of the high specialisation in research, such new information diffuses only slowly out of the circles of experts into clinical practice. Therefore, it was a most rewarding initiative of the Bayer Company to sponsor a conference which aimed at a mutual exchange of ideas between clinicians and researchers who are experts in either hypertension or diabetes.

"Endocrine and Metabolic Disease" is in two sections. The first is a systematic review of clinical and therapeutic aspects of endocrine diseases, whilst the second considers the clinical pharmacology of drugs used in endocrinology. All the major areas of endocrinology and metabolism are covered. Thyroid, adrenal and pancreatic disease are discussed in depth and there are separate chapters on the ovary and testes as well as on the pituitary gland and parathyroids. There is a useful pharmacopoeia of drugs used in endocrinology at the end of the volume.

Ideo autem omnes ad consilium vocari diximus, quia saepe iuniori Dominus revelat quod melius est. * Benedictus de Nursia Regula Benedicti, ca. 550 A. c. Caput III,3 The Wilsede Meetings were initiated in 1973 as an unusual experiment, and in the meantime this biennial symposium has already come to constitute an established and successful tradition. In June 1986 scientists and physicians met for the seventh time in the 3- year-old Emmenhof in Wilsede, in the heart of the Liineburg Heath, to dis- cuss modern trends in human leukemia. It was Pappenheim who in 1910 prepared the first international hematol- ogy congress. It was to have been held in Berlin under the title "Der groBe mononukleiire Leukozyt Ehrlichs, seine Morphologie und Funktion, seine Herkunft und seine Benennung" (Ehrlich's large mononuclear leukocyte. Its morphology, function, origin, and name), which was the most important and topical question at that time. It is amazing to think that as early as 1900, thanks to the pioneering research of Maximov and the innovative staining method developed by Ehrlich, the differentiation of the blood cells had, to a large extent, already been discovered. It is a sad fact that this congress never took place due to personal controversies among leading hematol- ogists, especially between Pappenheim and the Austrian hematologist Tiirk. Fortunately the Wilsede Meetings have never incurred this type of per- sonal controversies. On the contrary, both matter-of-fact discussions at a high scientific level and the development of personal friendships have always characterized their singular atmosphere.

Symposium on Lipoprotein Metabolism, held in Heidelberg, September 10-13, 1975

Metabolic disorder caused by altered levels of metabolism resulting pathophysiological abnormalities often leads to childhood death. Several new developments on metabolic diseases research have been emerging. Gaucher disease is a lysosomal storage disorder caused by glucocerebrosidase gene mutations resulting glucocerebrosidase deficiency. Current studies show that the same gene mutations also contribute to the Parkinson's disease. Tetrahydrobiopterin (BH4) has been widely used in treating patients with Phenylketonuria over a decade. Recent studies reveal that patients treated with BH4 over one-year period showed reduced levels of serum B12, folate and iron intake and therefore patients under chronic BH4 treatment needed to be advised to have additional micronutrients along with BH4. Macrocephaly was used as one of the important features to diagnose Canavan disease. However, a recent study showing a child with aspartoacylase gene mutation developed microcephaly. Hence, Canavan disease phenotype can be either macrocephaly or microcephaly. These are a few examples of recent developments on metabolic diseases research. Therefore, this book was aimed to compose current developments on metabolic diseases research for the use by broad spectrum of experts including Physicians, Neuroscientists, Neurologists, Biomedical researchers, Biochemists, Molecular biologists, Basic Science Researchers and Medical Students.

The Plasticity of Sex: The Molecular Biology and Clinical Features of Genomic Sex, Gender Identity and Sexual Behavior provides a comprehensive view on the development of human sexuality. As there has been a crescendo of interest over the past several decades about the nature and diversity of human sexuality, this reference brings the evidence-based research into one place. The emergence of issues surrounding gender identity, genital ambivalence and the transition from one sex to another is striking, with the public and treating physicians alike clamoring for an evidence-based, comprehensive treatment of human sexuality and all its variations. This is a must-have reference for biomedical researchers in endocrinology, neuroscience, development biology, medical students, residents, and practicing physicians from all medical areas.
