Download or read book Prostaglandins and Leukotrienes in Gastrointestinal Diseases written by W. Domschke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: In OCtober 1986, recognized authorities from a variety of disciplines met in Lisbon, Portugal, to review recent knowledge on eicosanoids - i. e., prostaglandins, throm boxane A , and leukotrienes - and their role in gastrointestinal diseases. 2 Briefly, in the stomach endogenous as well as exogenous prostaglandins may mediate cytoprotective actions in that they stimulate gastric mucus production, bicar bonate secretion and cellular regeneration while providing adequate mucosal blood flow. In contrast, thromboxane A2 by vasoconstriction may act as an ulcerogenic substance. Diarrheal states may be associated with prostaglandins of types E and F as they are capable to enhance intestinal water and electrolyte secretions. In chronic in flammatory bowel disease, mucosal synthesis of leukotrienes was found to be increased more markedly than that of prostaglandins suggesting that leukotrienes may have a major part in the pathogenesis of that disease. In this volume, which is an elaborated collection of the papers given on occasion of the above-mentioned symposium, the facts and problems associated with prostanoid substances are dealt with in four sections on 1. biochemistry, biology and pharmacology of eicosanoids, 2. physiologic and pathophysiologic aspects, 3. established therapeutic implications, and 4. treatment perspectives. We believe that the publication of these contributions by leading workers in the given fields provides a comprehensive and up-to-date appraisal of the role of eicosanoids in gastrointestinal diseases, and it is hoped that this volume will be of value to both basic scientists and practicing clinicians.
Download or read book Cooperation of Liver Cells in Health and Disease written by Z. Kmiec and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is only during the last decade that the functions of sinusoidal endothelial cells, Kupffer cells, hepatic stellate cells, pit cells and other intrahepatic lymphocytes have been better understood. The development of methods for isolation and co-culturing various types of liver cells has established that they communicate and cooperate via secretion of various intercellular mediators. This monograph summarizes multiple data that suggest the important role of cellular cross-talk for the functions of both normal and diseased liver. Special features of the book include concise presentation of the majority of detailed data in 19 tables. Original schemes allow for the clear illustration of complicated intercellular relationships. This is the first ever presentation of the newly emerging field of liver biology, which is important for hepatic function in health and disease and opens new avenues for therapeutic interventions.

Download or read book Endogenous Mediators of Gastrointestinal Damage written by John L. Wallace and published by CRC Press. This book was released on 1989-09-30 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text helps the reader determine whether or not the gastrointestinal mucosa ulcerates can be viewed as a balance between aggressive factors present in the lumen and the mucosal defence system. Several of these aggressive factors, such as acid, bile and pepsin, are endogenous substances. Similarly, several endogenous substances exert control over mucosal blood flow and secretion and thus are important mediators of mucosal defence. In this volume, experts in this field have contributed chapters on some of the most important of these endogenous mediators, including histamine, prostaglandins, leukotrienes and platelet-activating factor. The potential contribution of these mediators to gastrointestinal disease has been assessed. Also discussed is the role these mediators play in gastrointestinal side effects of drugs (i.e. non-steroidal anti-inflammatory drugs). Also covered are the mechanisms of action of endogenous mediators relative to the the drugs used clinically for the treatment of maladies of the digestive system. This volume will be of interest to the basic scientist, the clinical investigator and to students of pathophysiology and medicine.

Download or read book Inflammation and the Microcirculation written by D. Neil Granger and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microcirculation is highly responsive to, and a vital participant in, the inflammatory response. All segments of the microvasculature (arterioles, capillaries, and venules) exhibit characteristic phenotypic changes during inflammation that appear to be directed toward enhancing the delivery of inflammatory cells to the injured/infected tissue, isolating the region from healthy tissue and the systemic circulation, and setting the stage for tissue repair and regeneration. The best characterized responses of the microcirculation to inflammation include impaired vasomotor function, reduced capillary perfusion, adhesion of leukocytes and platelets, activation of the coagulation cascade, and enhanced thrombosis, increased vascular permeability, and an increase in the rate of proliferation of blood and lymphatic vessels. A variety of cells that normally circulate in blood (leukocytes, platelets) or reside within the vessel wall (endothelial cells, pericytes) or in the perivascular space (mast cells, macrophages) are activated in response to inflammation. The activation products and chemical mediators released from these cells act through different well-characterized signaling pathways to induce the phenotypic changes in microvessel function that accompany inflammation. Drugs that target a specific microvascular response to inflammation, such as leukocyte-endothelial cell adhesion or angiogenesis, have shown promise in both the preclinical and clinical studies of inflammatory disease. Future research efforts in this area will likely identify new avenues for therapeutic intervention in inflammation.

Download or read book Selective COX 2 Inhibitors written by Sir John R. Vane and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mainstay of therapy for rheumatoid disease is the non-steroid antiinflammatory drugs (NSAIDs), despite their inherent gastrointestinal toxicity and ability to cause renal damage in susceptible patients. The theory that the beneficial and toxic effects of NSAIDs stem from a reduction in prostanoid production through inhibition of cyclooxygenase implied that particular toxicities were inevitable with NSAIDs and would always be correlated with efficacy. However, over the years, it became apparent that at therapeutic doses, some NSAIDs had greater toxic side-effects than others, a fact not explained by the general theory. A significant clarification arose from the discovery that there are two distinct isoforms of COX, a constitutive enzyme (COX-I) responsible for the production of prostanoids necessary for platelet aggregation and protection of the gastric mucosa and kidney; and an inducible enzyme (COX-2) that is newly synthesized at sites of tissue damage and produces prostaglandins that manifest pathological effects. It became clear that different NSAIDs had greater or lesser effects on COX-I when used in therapeutic doses, explaining the variation in side-effects. ' The elucidation of the crystal structure of these different enzymes and the skills of medicinal chemists have led to the synthesis of new chemicals with a selectivity for the inducible enzyme, and thus with therapeutic efficacy without those toxic effects result ing from inhibition of the constitutive enzyme.

Download or read book Pharmacology of Immunotherapeutic Drugs written by Clinton B. Mathias and published by Springer Nature. This book was released on 2019-10-18 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medicine has entered a golden age in which therapeutic agents are becoming widely available due to advances in basic science and technology. As such, many drugs have been developed that target inflammatory processes and/or the immune system. This book is intended for health professionals examining the modulation of inflammation by immunotherapeutic drugs. The immune system fills the primordial role of host defense and resistance to infections with pathogenic microorganisms. Several hematopoietic-derived cells constituting the innate and adaptive immune systems cooperate to provide barriers for microbial colonization and/or promote pathogen destruction within the host. Conversely, many immune cells are also involved in the pathogenesis and propagation of chronic inflammatory diseases. The beginning of this book details various components of the immune system including the cell types, lymphoid tissues, soluble cytokines and surface molecules that are essential for host defense. Breakdowns in immune tolerance, or dysregulated immune responses to antigens derived from self tissues or innocuous sources, can lead to the development of autoimmunity or chronic inflammatory diseases. Pathophysiologic roles for the immune system are detailed in corresponding chapters on autoimmunity, epithelial surfaces (lungs, skin, intestine), and transplantation, with special emphasis placed on immunotherapeutic drug targets. The last section of the book focuses on treatments that stimulate our immune system to specifically target and fight infectious diseases and cancer. In each chapter, the medications used to treat various diseases/conditions in terms of their mechanism of action and other pharmacologic properties are detailed. Chapters begin with a table showing drug names and classifications. The importance of basic science and clinical trials cannot be understated in the context of drug development. As such, the discovery of certain medications that had a lasting impact in medicine and pharmacy are highlighted in chapter subsections named “Bench to Bedside.” Several clinical applications of immunotherapeutic drugs are described within end-of -chapter case studies including practice questions. The Pharmacology of Immunotherapeutic Drugs is a reference for immunologists and clinicians (medical doctors, pharmacists, nurses) examining the modulation of inflammatory processes by a variety of medications targeting the cells and mediators of our immune system.
