Measurements Of Exocrine And Endocrine Functions Of The Pancreas

The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Without the exocrine pancreas, malabsorption and malnutrition result. This chapter describes the cellular participants responsible for the secretion of digestive enzymes and fluid that in combination provide a pancreatic secretion that accomplishes the digestive functions of the gland. Key cellular participants, the acinar cell and the duct cell, are responsible for digestive enzyme and fluid secretion, respectively, of the exocrine pancreas. This chapter describes the neurohumoral pathways that mediate the pancreatic response to a meal as well as details of the cellular mechanisms that are necessary for the organ responses, including protein synthesis and transport and ion transports, and the regulation of these responses by intracellular signaling systems. Examples of pancreatic diseases resulting from dysfunction in cellular mechanisms provide emphasis of the importance of the normal physiologic mechanisms.

This innovative teaching atlas provides the reader with a practical approach to the diagnosis and management of the common and uncommon diseases that may involve the pancreatic gland. Its perspective is multidisciplinary, the authors being radiologists, surgeons, pathologists, and gastroenterologists who have worked together for the past 25 years. Very concise descriptions of clinical presentation, pathology, imaging, and management are provided for a great variety of pathologic conditions, and a wealth of illustrative material displays intraoperative appearances, gross specimens, histology, and radiological findings. Pancreatic surgery, including transplantation, is also discussed, and the final chapter presents a gallery of challenging and diverse cases. Specialists and residents in a range of specialties will find this atlas to be an invaluable aid, and it will also serve as an excellent reference for medical students.

A comprehensive reference standard for the discipline, Canine and Feline Gastroenterology covers the biology, pathobiology, and diagnosis and treatment of diseases of the gastrointestinal, pancreatic, and hepatobiliary systems. An international team of experts, including 85 authors from 17 different countries, led by Robert Washabau and Michael Day, covers everything from minor problems such as adverse food reactions to debilitating inflammatory, infectious, metabolic, and neoplastic diseases of the digestive system. This authoritative text utilizes an evidence-based approach to reflect the latest science and research, complemented by principles of problem solving, algorithms to improve clinical diagnoses, and extensive full-color illustrations. For generalists and specialists alike, this gastroenterology reference should be part of every serious practitioner's professional library. A comprehensive, 928-page reference standard covers the discipline of canine and feline gastroenterology. An international focus is provided by 85 authors from 17 different countries, including renowned experts in veterinary gastroenterology, internal medicine, pathology, clinical pathology, radiology, and infectious disease. Coverage of the entire breadth and depth of gastroenterology ranges from biology to pathobiology, as well as diagnosis and treatment of diseases of the gastrointestinal, pancreatic, and hepatobiliary systems. Current information on GI microflora, immunology, cellular growth, and systems integration provides a foundation for treating clinical problems. Coverage of diseases in dogs and cats includes the oral cavity, esophagus, stomach, small intestine, large intestine, colon, anorectum, liver and biliary tract, exocrine pancreas, peritoneum, and associated vasculature. A focus on patient management examines the full range of procedures and techniques essential to diagnosis and treatment from clinical signs and diagnosis to nutritional support and pharmacologic management of disease. Clear explanations of current diagnostic modalities include laboratory tests, molecular methods, diagnostic imaging, endoscopy, and histopathology, also showing how to interpret and utilize results. A strong clinical approach emphasizes need-to-know information for managing the common and not-so-common G.I. clinical problems of everyday practice. Full-color photographs and illustrations depict concepts, conditions, and procedures. An evidence-based medicine perspective reflects the latest research as well as the modern practice of veterinary medicine. Logical, coherent, and consistent internal organization makes this a reader-friendly edition. Problem-based algorithms help in diagnosing every G.I. clinical problem from A to Z. A stand-alone section on the pharmacologic approach to G.I. disease offers quick and easy drug reference.

The first edition of Color Atlas of Fetal and Neonatal Histology was an important step in updating the histology texts available to practicing pathologists and pathology trainees who perform fetal autopsy and/or participate in research involving fetal tissues. It was a well-received volume that filled a major gap in pathology references related to normal histology and provided a comprehensive, state-of-the art review of fetal and neonatal histology. While the basics of fetal histology have changed little in the intervening years since publication of the first edition, this successor edition provides new insights and a fresh perspective. This book contains six new chapters including: blood vessels and lymphatics, external genitalia, eye, ear, skin, and maceration changes. Many existing chapters have also been expanded to address a greater breadth of fetal and neonatal histology such as postnatal testis development and the cardiac conduction system. The “Special Considerations” sections were also expanded in many chapters to address particularly problematic issues within individual organ systems. The book reviews the histology of the major organ systems in the fetus and neonate and provides detailed images, up-to-date references, and practical guidelines for identifying tissues across all gestational ages of development. The second edition of Color Atlas of Fetal and Neonatal Histology serves as the ultimate go-to resource for pathologists and researchers dealing with, and interested in, fetal and neonatal histology. It provides a comprehensive summary of the current status of the field with excellent and extensive illustrative examples that help guide the clinical study of fetal and neonatal histology and stimulate investigative efforts with fetal tissue.
