Then the characteristics of some key calcium transport systems (calcium channels, sodium/calcium exchange and SR calcium uptake and release) are discussed in detail. This is then built into a more integrated picture of calcium regulation in succeeding chapters by detailed discussions of excitation-calcium coupling mechanisms (in skeletal, cardiac, and smooth muscle), the interplay between calcium regulatory processes, and finally mechanisms of cardiac inotropy, calcium overload, and dysfunction (e.g., ischemia, hypertrophy, and heart failure).

The main aim of this monograph is to provide an overview of calcium regulation in cardiac muscle cells, particularly with respect to excitation-contraction coupling and the control of cardiac contractile force. It is my hope that this book will be useful to students of the cardiovascular system and muscle at all different levels and in different disciplines (such as physiology, biochemistry, pharmacology and pathophysiology). I also hope that it will find use for those studying developmental, comparative and disease processes as well as more integrative phenomenon. I kept several goals in mind in writing this monograph. First, it should be easily readable. Second, I chose to include numerous illustrations and tables to help integrate results from numerous investigators in practical formats and also present key figures from important papers. Thus, this monograph may serve as a resource of information for people working in the areas described herein. Third, the presentation is a very personal one, and I have necessarily drawn extensively on my personal experience in this field over the past 15 years. This, I think, helps maintain a certain continuity of thought from chapter to chapter. Fourth, I have made serious attempts to make each chapter "up to date", despite the breadth of topics covered. I have also tried to be equitable in choosing references while not intending to be comprehensive or exhaustive. Neither of these aims can be perfectly matched, and I apologize to the many investigators whose papers I have not cited, but should have.

Advances in Physiological Sciences, Volume 27: Factors Influencing Adrenergic Mechanisms in the Heart is a collection of papers presented at the 1980 satellite symposium of the 28th International Congress of Physiological Science, held in Visegrád, Hungary. This symposium covered the achievements that modify the traditional views of adrenergic regulation of cardiac muscle and coronary blood vessels. This volume is composed 18 chapters and begins with a discussion of the effect of adrenaline on some aspects of electrical and mechanical activity in the frog heart. The subsequent chapters describe the heart rate changes in neurogenic hypertension, the developmental changes of the catecholamine-induced chronotropic responses related to the blood pressure responses, and the inverse reciprocal regulation of cardiac post-synaptic a- and b-adreneceptors by thyroid hormones. Other chapters deal with the mechanism of adenosine-induced inhibition of adrenergic neurotransmission in the ventricular myocardium; the comparative morphological studies of localized exogenous adenosine in heart muscle; adenosine sensitivity of canine coronaries; and the significance of nickel ion in the coronary vascular tone regulation. These chapters are followed by discussions of the physiological and pathological effects of beta modulator release and the histological study of experimental diabetic angiopathy. The last chapters examine some aspects of myocardial noradrenaline metabolism in the ischemic heart and the activity of alpha-adrenoceptor without employing beta blocking agents.

Drug discovery and development is a challenging, expensive and time consuming field of research, requiring contributions from chemists, pharmacologists, toxicologists, clinicians, and practitioners. The ultimate goal is to generate a safe and biologically active drug which can stall, or even reverse, the pathological events that cause the disease condition. But in the search for the drug a host of tests and trials must be applied to evaluate the efficiency and safety of the newly developed molecule in the biological system. These trials or "screening methods" are critical. On their basis, the new molecule either becomes accepted for usage, or is discarded forever. Advances in drug research have forced the need for quicker, more automated screening methods, using molecular techniques applied in vitro, in vivo and in clinical systems. Researchers need to know the latest developments outside their own speciality. With this book, Professor Gupta has brought together in one coherent volume the most up to date developments of consolidated screening methods for biological systems. By paying attention to the practical techniques used in academia and the commercial pharmaceutical industry, "Drug Screening Methods" will enjoy a broad readership, serving both the professional community and the student of pharmacology.

Cardiac Dynamics

Cardiac Dynamics is the name of a relatively young field of study, born from the fruitful interaction between branches of two different disciplines: medicine and physics. "Dynamics" is the branch of physics which deals with the action of forces on bodies or particles in motion or at rest. "Cardiac" relates to the clinical field of cardiology but also to cardiophysiology, both of which are specialized branches of medicine. Narrower than the well established field of Hemodynamics, Cardiac Dynamics is restricted to dynamic phenomena occurring in and around the heart. The mathematical treatment of such phenomena, however, is vastly more complex because of the intricate nature of the mechanisms involved in the cardiac action. Thus, whereas hemodynamics is concerned with predominantly passive (visco-) elastic structures - vessels - containing time-variant flow of viscous flui- blood -, the mechanical study of the heart requires additional con siderations such as: active elastic components representing the contractile mechanism of cardiac muscle, complex geometry and fiber structure in the myocardial wall, autoregulatory mechanisms, and intricate flow patterns associated with valve motion. Viewed in this light it is not surprising that attempts to describe ventricular pump function and to quantify contractile performance have not reached the level of sophistication which is common in e. g. arterial hemodynamics. For the same reason, many of the often simplified approaches to describe ventricular mechanics failed to stand up to more rigorous theoretical, experimental or clinical testing.

AMI E. ISKANDRIAN & ERNST E. VAN DER WALL The first edition of this book was published in 1994. Since then important advances have occurred in the field of myocardial viability. This, coupled with increasing interest by the scientific community in the broader issues of its relevance to patient care, suggested to us the need to write the second edition. We are most fortunate to have the help of a distinguished group of experts who have helped shape the field; we appreciate their commitments and contributions. Almost all chapters have been radically modified. Chapter 1 deals with pathophysiology of myocardial hibernation and stunning; Chapter 2 with apoptosis; Chapter 3 with the role of positron emission tomography; Chapters 4 and 5 with the role of single photon emission computed tomography with thallium-201 and technetium agents, respectively; Chapter 6 with the role of SPECT fatty acid imaging; Chapter 7 with the role of SPECT FDG imaging; Chapter 8 with the role of cardiac catheterization angiography; Chapter 9 with the role of echocardiography; Chapter 10 with the role of magnetic resonance imaging; and Chapter 11 with clinical applications. Finally, Chapter 12 provides a short summary.

In June 1989, a third conference concentrating on the progress in quantita tive coronary angiography and related techniques was held in Rotterdam, again very successful as the two preceding events in 1985 and 1987. Tech nical as well as clinical aspects of digital and digitized coronarography, morphometry, parametric imaging and functional quantification of the human coronary circulation were presented and discussed by prominent exponents of those groups who have been active in this particular field for many years. This book contains the chapters representing the lectures held by leading experts during the symposium that update the knowledge currently available, including most recent aspects in angioscopy and intravascular ultrasound imaging. It also includes a historical review on the development of angiogra phic techniques from the very early days on to our times given by one of the pioneers in heart catheterization and angiography, Dr. Kurt Amplatz. Those who had the chance to listen to his talk, will surely remember his impressive, humorous lecture as one of the highlights of this meeting.
