Available in PDF, EPUB and Kindle. Book excerpt: Since the exhaustive Handbook of Physiology (Alimentary Canal, Section 6, Motility) edited by CHARLES F. CODE in 1968, no complete survey of the morphological basis and the physiological control of intestinal motility has been published, in spite of the enormous amount of new data in the literature on this topic. The new techniques and methodologies, the use of electron microscopy, radioimmunoassay and binding techniques, as weIl as ever more sophisticated electrophysiological procedures have made possible areal flood of discoveries in this field. Moreover, the possibility ofnew studies ofthe endocrine cells in biopsies of human intestinal mucosa even during routine endoscopies, has opened new horizons for gastroenterologists and generated a number of important contribu tions to our knowledge of the morphology and physiopathology of the gut. As usual, new discoveries have also revealed both ignorance and many new problems. For tbis reason, although many of the data reported in this volume can be considered as firmly established, others still require confirmation, and the results of new research in this field are awaited with extreme interest. Since advances are occurring so rapidly, even experts in the specific topics need frequent comprehensive reviews. To avoid an excessively large volume, considera tions ofthe pancreas, liver, and biliary system were not included in this Handbook, which, nevertheless, has attempted to off er the reader the essence of more than 1,500 papers.

This book was released on 2012-12-06 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume places more emphasis on endogenous mediators of gut motility than on drugs used to treat patients with deranged motility. In this respect it resembles most other books on gastroenterology, for while only a relatively small number of drugs are really useful for a rational therapy, a tremendous amount of data is available on neural and hormonal factors regulating the motility of the alimentary canal. Moreover, it must be considered that some of the drugs which can routinely be employed to modify deranged motility of the digestive system are represented by pure or slightly modified endogenous compounds (e. g. , cholecystokinin, its C terminal octapeptide and caerulein), and it is easy to foresee that their number is destined to increase in the near future. Other drugs are simply antagonists of physiological substances acting on specific receptors (e. g. , histamine H -blockers 2 and opioid compounds). The real explosion of research in this field and the extreme specialization often connected with the use of very sophisticated techniques and methodologies would probably have required a larger number of experts to cover some very specific fields from both an anatomical (lower esophageal sphincter, stomach, pylorus, small and large intestine) and a biochemical (hormones, candidate hormones, locally active substances, neurotransmitters etc. ) point of view.

Book Synopsis Colonic Motility by : Sushil K. Sarna
Download or read book Colonic Motility written by Sushil K. Sarna and published by Biota Publishing. This book was released on 2010-11-01 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three distinct types of contractions perform colonic motility functions. Rhythmic phasic contractions (RPCs) cause slow net distal propulsion with extensive mixing/turning over. Infrequently occurring giant migrating contractions (GMCs) produce mass movements. Tonic contractions aid RPCs in their motor function. The spatiotemporal patterns of these contractions differ markedly. The amplitude and distance of propagation of a GMC are several-fold larger than those of an RPC. The enteric neurons and smooth muscle cells are the core regulators of all three types of contractions. The regulation of contractions by these mechanisms is modifiable by extrinsic factors: CNS, autonomic neurons, hormones, inflammatory mediators, and stress mediators. Only the GMCs produce descending inhibition, which accommodates the large bolus being propelled without increasing muscle tone. The strong compression of the colon wall generates afferent signals that are below nociceptive threshold in healthy subjects. However, these signals become nociceptive; if the amplitudes of GMCs increase, afferent nerves become hypersensitive, or descending inhibition is impaired. The GMCs also provide the force for rapid propulsion of feces and descending inhibition to relax the internal anal sphincter during defecation. The dysregulation of GMCs is a major factor in colonic motility disorders: irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and diverticular disease (DD). Frequent mass movements by GMCs cause diarrhea in diarrhea predominant IBS, IBD, and DD, while a decrease in the frequency of GMCs causes constipation. The GMCs generate the afferent signals for intermittent short-lived episodes of abdominal cramping in these disorders. Epigenetic dysregulation due to adverse events in early life is one of the major factors in generating the symptoms of IBS in adulthood.
Book Synopsis Neural Control of Gastrointestinal Function by : David Grundy
Download or read book Neural Control of Gastrointestinal Function written by David Grundy and published by Morgan & Claypool Publishers. This book was released on 2011-12 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: The gastrointestinal tract is a long, muscular tube responsible for the digestion of food, assimilation of nutrients and elimination of waste. This is achieved by secretion of digestive enzymes and absorption from the intestinal lumen, with different regions playing specific roles in the processing of specific nutrients. These regions come into play sequentially as ingested material is moved along the length of the GI tract by contractions of the muscle layers. In some regions like the oesophagus transit it rapid and measured in seconds while in others like the colon transit is measured in hours and even days, commensurate with the relative slow fermentation that takes place in the large bowel. An hierarchy of controls, neural and endocrine, serve to regulate the various cellular targets that exist in the gut wall. These include muscle cells for contraction and epithelial cells for secretion and absorption. However, there are complex interactions between these digestive mechanisms and other mechanisms that regulate blood flow, immune function, endocrine secretion and food intake. These ensure a fine balance between the ostensibly conflicting tasks of digestion and absorption and protection from potentially harmful ingested materials. They match assimilation of nutrients with hunger and satiety and they ensure that regions of the GI tract that are meters apart work together in a coordinated fashion to match these diverse functions to the digestive needs of the individual. This ebook will provide an overview of the neural mechanisms that control gastrointestinal function.

Available in PDF, EPUB and Kindle. Book excerpt: Gastrointestinal motility has evolved from an esoteric laboratory tool into a sophisti cated diagnostic technique that is now widely used clinically to guide in management of complex gastrointestinal problems. Today, it is the most rapidly growing subspecialty within gastroenterology. Previously, many of the gastrointestinal motility problems were either ignored or attributed to a disturbance of "psyche." But with the growing knowledge and understanding of how a dysfunction of the gastrointestinal muscle and nerves can cause disease, we are at the threshold of a revolution in our approach to the diagnosis and treatment of gastrointestinal motility disorders. The purpose of this book is to serve as a useful, up-to-date reference manual and guide for the diagnostic and therapeutic approach towards common adult and pediatric gastrointestinal motility problems. In order to enhance the understanding of these disor ders, a problem-oriented approach has been chosen, and wherever possible the authors have provided clinical case scenarios to illustrate their message. The emphasis has been on how to diagnose and treat motility disorders rather than to provide an encyclopedic infor mation. The reference list at the end of each chapter should enable the enthusiast to seek further information. Some of the material presented in this book has been derived from the proceedings of the annual University ofIowa College of Medicine GI Motility Symposia.
