Toxic Interactions
1 Edición
Robin S. Goldstein + 2 más
Inglés
Toxic Interactions is a collection of papers that discusses the basic principles behind the mechanism of toxicological interactions. This book deals with interacting chemicals and their effects on certain exposed organs or molecules. Concerning discussion of the principles, contributed papers explain the role of xenobiotic biotransformation processes in inactivating reactive intermediates of toxicants. Other authors discuss the effects of endogenous molecules and the consequences of chemically induced depletion of protective agents, as well as the pharmacokinetic principles that affect chemical interactions. Several authors also review experiments on the types of chemicals that produce or increase the degree of toxicity. The text reviews the results of liver and kidney injuries from exposure to two or more chemicals, while other papers focus on lung and heart toxicity. For example, direct mechanism of cardio toxicity includes toxicity due to an increase in plasma concentrations of the compound, or as in latent cardiac toxicity that is a product of another action on another system of organs. Professors in pharmacology, practitioners of general medicine, specialists or researchers dealing with microchemistry, toxicology or drug therapy will find this reference valuable.
Pharmacology of Central Synapses
1 Edición
V. V. Zakusov
Inglés
Pharmacology of Central Synapses deals with the pharmacology of the central nervous system and the mode of action of neurotropic drugs based on their influence on synaptic transmission. The neuronal structure of the nervous system, the structure of the synapses, and the phenomena of electrochemical transmission are discussed in this context. The main propositions of the synaptic theory of the action of neurotropic drugs, based on morphological, physiological, and biochemical findings, form the conceptual basis of this book. Comprised of eight chapters, this book examines the effect of neurotropic drugs on the synaptic transmission in reflex, projection, and association (commissural) tracts. The specific effects of various narcotics, neuroleptics, tranquillizers, analgesics, antidepressants, and stimulants on synaptic transmission in various structures of the central nervous system and at its different levels are described. This text also considers the differences in the sensitivity to such drugs of various synapses and their influence on the selectivity of drug action. This book explains the influence of neurotropic drugs on such aspects of nervous activity as impulse summation, after-discharge and functional lability, central inhibition, and the neurochemical mechanisms, particularly those involving monoaminergic, cholinergic, serotoninergic, and GABA-ergic components of synaptic transmission. The final chapter focuses on the effect of psychotropic drugs on behavior. This book will be helpful to scientists representing all the major areas of pharmacology, including clinical pharmacology and toxicology, as well as to internists, psychiatrists, neurologists, and anesthesiologists.
Physiology and Toxicology of Male Reproduction
1 Edición
James C. Lamb + 1 más
Inglés
Physiology and Toxicology of Male Reproduction is a collection of papers that deals with general reproductive biology and specific aspects of reproductive toxicology, pertaining to the male sex. Some papers discuss testicular organization, reproductive toxicity testing systems, and germ-cell genetic toxicology. The use of in vitro systems by investigators to dissect the male reproductive toxicants can lead to a more scientific approach toward hazard assessment and the development of safer drugs and chemicals. Other papers explain the fundamental reproductive biology of the testis, the neuroendocrine system, the epididymis and accessory sex organs, and spermatozoal evaluation. Toxicological aspects cover the toxicological evaluation of the complete reproductive system, testicular morphology, sperm assessment, and germ-cell mutagenesis. One paper describes alternative methods in toxicology—by using new in vitro systems that should reduce or eliminate the need for tests conducted on animals. In vitro methodology embraces other systems such as from subcellular fractions to isolated intact organs. In relation to target-organ toxicity, the researcher can focus using primary cell cultures. This collection will prove helpful to toxicologists, graduate students and researchers in biology, particularly in male reproductive toxicology and fertility testing.

Blood

Walter S. Root + 1 más
Inglés
Physiological Pharmacology, Volume V: Blood describes the interrelationships between pharmacology and blood. This volume is organized into five parts encompassing 16 chapters that consider the effect of therapeutic agents on the physiology of blood, whether it be coagulation, the white cells, red cells, or platelets. The opening part deals first with the physiology of blood coagulation and the mode of action of anticoagulants. This part also covers the mechanism of thrombogenesis and thrombolysis, as well as the in vivo actions of thrombolytic agents. The subsequent parts initially examine the biochemistry and physiology of platelets, hematopoietic stem cells, and white cells. These topics are followed by discussions of the mechanism of thrombocytosis and clinical manifestations of thrombocythemia, as well as the mechanisms of immunologic drug effect on blood cells. These parts also explore the effects of drugs on myelopoiesis and the physiological and immunological activities of lymphocytes. The closing part reviews the iron, vitamin B12, folic acid, erythropoietin, and transferrin components of red blood cells. This part also examines the mechanism of erythropoietic cellular proliferation and the initiation of hyperoxia. This book is intended primarily to physiological pharmacologists, hematologists, and researchers.

Advances in Drug Research, Volume 22 focuses on the concepts and facts of drug research. This book is divided into four chapters. Chapter 1 discusses the use of atomic properties and atom-centered indices in QSAR models, while Chapter 2 describes the pharmacokinetics of peptides and proteins. The nuclear receptors, emphasizing the aspects of molecular and genomic pharmacology are elaborated in Chapter 3.

Cardiac Pharmacology
1 Edición
R. Douglas Wilkerson
Inglés
Cardiac Pharmacology aims to interface basic and clinical knowledge of those interventions used or being studied for use in the treatment of heart disease. The book is divided into four major sections which address intrinsic and neural control of cardiac function, pharmacologic modification of cardiac contractility and cardiac output, the genesis and control of cardiac arrhythmias, and pharmacologic manipulation of myocardial oxygen supply and demand. The last three sections contain a chapter describing the techniques employed in the study of that particular aspect of cardiac function and its alterations by pharmacologic interventions. Cardiologists, pharmacologists, physiologists, and those interested in the area of cardiovascular medicine will find the book insightful.
