The two kidneys of mammalian organisms receive around 25 % of the cardiac output at rest, of which only 7 % is distributed to the renal medulla. Despite the low blood flow to the renal medulla, small changes in perfusion to the region can have profound effects on urine-concentrating ability and the excretion of sodium, which in turn affects the chronic regulation of body fluid volumes and arterial blood pressure. Importantly, we know that if blood flow to the renal medulla is not tightly regulated, sodium and water homeostasis is impaired and medullary hypoxia develops. The resultant injury inevitably reduces urine concentrating ability and leads to hypertension. This book will discuss the variety of mechanisms that mammalian organisms have developed to ensure that renal medullary blood flow and oxygen levels are precisely regulated. This book will focus on the unique anatomical arrangement of the medullary circulation, the functional roles of medullary blood flow, as well as the experimental techniques used to assess medullary blood flow and the insight that these studies have provided. The hormonal and non-hormonal control of medullary blood flow will be considered and finally the impact of reduced medullary blood flow on blood pressure is discussed.

Kathleen and 24 of her fellow patients provide easy-to-read helpful tips and share their personal experience, that is both useful and informative. This book will certainly assist those who are currently on dialysis or about to start it. Dialysis is not easy, but this information may give you a much better understanding and change the way you feel about it. Attitude is most important. Staying positive and finding some new ways to combat the negatives just might make it a whole lot easier.

Gabriel of Urantia asked the question, in the beginning of his struggle with dialysis, "God, why is this happening to me?" Throughout his 8-month dialysis experience, 3 days a week, 4 hours a day, being tied down to a chair while his blood flowed from his body through a machine and back, he realizes-from the people he meets also on dialysis and in the hospitals after post-kidney-transplant-that very bad things happen to very good people. He met young and old alike, tied down to the machines just like he was, and the young people were the hardest for him to resolve in his mind with God and also to try to give them hope. As a minister, he felt obligated to do so. Being a Pastor of a church (Global Community Communications Alliance-a very social, environmental, and spiritual activist church), he knew that bad things happened to good people who try to change the world. But this disease is personal, between him and God you might say. So he had to discover for himself why God allowed this to happen to him and to the other very good people he met with various traumatic illnesses in the hospitals and dialysis centers. Gabriel of Urantia tries to explain how he felt along the path, from the beginning to the receiving of his new kidney from his 22-year-old daughter and gaining the hope and health to continue not only his spiritual work, but his work as a musician, guitar player, and singer (in which he was planning a tour around the country with his 11-piece Bright & Morning Star Band), while now taking immunosuppressant drugs to keep him alive. He had all the fears that a new transplant patient has. How long will the kidney last? What other affects do these drugs have on my body? He writes about his experience with the medical world, the services he experienced from both very qualified people and those not so qualified (experienced and inexperienced care givers), as well as the bureaucracy of the medical field and insurance companies (both private and governmental). He realized that often in the medical field, the right hand didn't know what the left hand was doing and the patient suffered the results. Beyond that, Gabriel of Urantia tries to give hope to people with life-threatening illnesses by sharing his faith in the Creator to all who may read his book. A must-read for anyone on dialysis or with any life-threatening illness, from a writer who went through this and can identify with what they are going through and give them hope through this trauma in their lives.

Heme oxygenases (HOs) are the enzymes responsible for the breakdown of heme and the generation of biliverdin/bilirubin and carbon monoxide (CO). The kidney is a complex organ consisting of many different cell types all working together for the single purpose of filtering the blood to eliminate waste products and conserving ions, minerals, and water necessary for life. HO enzymes and their products play a critical role in the normal function of the kidney as well as protecting the kidney from various insults including ischemia and exposure to nephrotoxins. For example, the HO metabolite, bilirubin, is a potent antioxidant which can limit damage to renal tubular epithelial cells following exposure to nephrotoxins associated with chemotherapy or traumatic injury. Another HO metabolite, CO, is an important vasodilator of renal blood vessels and helps protect against severe decreases in renal blood flow in conditions as diverse as exposure to radiocontrast agents and in hypertension-induced kidney disease. HO and its metabolites also play an important role in the survival of kidney cells after acute and chronic injuries by regulating important cell growth and programmed cell death pathways. The intent of this volume is to highlight the important role that HO enzymes and their related metabolites, bilirubin and CO, play in the regulation of renal function and in the response of the kidney to both acute and chronic pathologies.

This unique volume may very well foreshadow the treatment of renal disease in the twenty-first century. The editors have obviously compiled and reviewed the current clinical problems in which the kidney plays a major role. They then selected as topics for chapters those in which recent scientific investigations have added significant new data. The investigators themselves or their peers have been persuaded to produce a summary of current concepts of renal structure and function for each topic. The result is a volume which will be as invaluable as a clinical guide on the laboratory bench as it will be a reference for the clinician seeking guidance to rational therapy at the bedside. The strength of the volume lies in the incorporation of those data on renal cellular structure and function which hold the key to the etiology of the majority of renal diseases we now call 'end-stage'. Fully, two-thirds of the volume is devoted to current concepts of renal function and related subcellular structure of various renal tissues. The illustrations, correlations, and explanations are superbly presented in much detail and with an obvious effort to fill out the current knowledge of each subject. We may anticipate this book will remain a valuable reference for many years to come.

Pathology of the Kidney in Dysproteinemia is an academic monograph describing in detail the causes and development of structural and functional changes in the human kidney resulting from the deposition of abnormal circulating serum proteins. The material presented was obtained from 147 cases of renal involvement associated with Dysproteinemia encountered in university and community hospital settings. The described entities account for 4.5% of 3.260 biopsies of native kidneys examined over a period of approximately 25 years. While some of the lesions are quite rare, others are relatively common and seen fairly frequently in a reasonably busy renal biopsy service. Together they constitute a group of extremely interesting lesions in terms of immunology, morphology, and pathogenesis.This book should be of interest to pathologists- especially renal pathologists, immunologists, and internists. Both general internists and sub-specialists in nephrology and hematology will find this volume useful, as will medical residents and medical technologists in these various specialties. As a monograph it is user-friendly, since the subject matter is sufficiently circumscribed to permit expanded or detailed visual and textual treatment of specific lesions in a single easy-to-wield volume.

The discovery of a potent vasoconstrictor, endothelin (ET)-1, derived from vascular endothelial cells was among a variety of key lines of investigation that helped to fuel a major explosion of studies related to endothelial cell biology. This was particularly evident within the pharmaceutical industry where receptor antagonists were quickly developed and are now on the market for treatment of pulmonary hypertension and in development for other diseases such as diabetic nephropathy and cancer. Importantly, we know that the kidney contains the highest level of ET-1 production and receptor expression in the body where it has been demonstrated to function as a pro-natriuretic autocrine and paracrine factor that is activated in conditions of high salt intake. This eBook provides a review of the various mechanisms whereby ET-1 has been shown to function within the kidney through a wide range of actions that include direct effects on tubular transport, intrarenal hemodynamics, as well as neural and endocrine functions. Much has yet to be discerned, but it is clear that the ET system is a major physiological regulator of fluid-electrolyte balance and blood pressure through these renal actions.

This manual contains protocols and guidance documents assembled by the authors during many years of clinical experience in nephrology. Many are not evidence-based but we have found them useful and hope that others will do likewise. The recommendations were made on the basis of clinical trials wherever possible. In the absence of relevant clinical trials, we used evidence available or our personal experience. Our aim was to provide a manual for the treatment of the most frequent kidney diseases or disorders related to the practice of Nephrology. The information may be of use to nephrologists, general internists, general practitioners or medical students.

Evidence-based Nephrology provides students of nephrology and practicing clinicians with a convenient single source of clinical evidence that has been passed through an evidence-based filter. This fully revised second edition incorporates substantial new available data, updated methods of research synthesis, and a renewed focus on consumer engagement in the evaluation and management kidney disease. This updated textbook includes twenty new chapters and three new sections, covering supportive care and patient-centered care and outcomes. In addition, every chapter that was in the first edition has been extensively updated. This new edition covers epidemiology, acute kidney injury, primary diseases of the kidney, secondary diseases of the kidney, chronic kidney disease and complications, hemodialysis, chronic kidney disease stage 5, peritoneal dialysis, supportive care, transplantation, electrolytes and acid-base disorders, and patient centered care and outcomes for both adult and for pediatric patients. Boasting a new co-editor along with several new chapter authors and section editors, Evidence-based Nephrology is now an even better evidence-based nephrology tool, where each chapter provides a clear foundation of the topic that is supported by the best current evidence. This new edition includes broader coverage of the available evidence and addresses crucial clinical questions regarding the treatment and care of people with all stages of chronic kidney disease, including people undergoing any form of dialysis (hemodialysis or peritoneal dialysis), those requiring kidney transplantation and pediatric patients. Evidence-based Nephrology, Second Edition, is a core resource for the evidence-based nephrology practitioner who is otherwise limited by time constraints from researching every question that may arise daily in the care of their patients.
