It is understood by Chronic Renal Failure (CRF) or Stage IV Chronic Kidney Disease (CKD) the morbid state in which there is a substantial and irreversible loss of functional capacity, metabolic and endocrine function in both kidneys, leading to a framework of dehydration, azotemia, electrolyte imbalance, anemia, uremic syndrome, secondary hyperparathyroidism, among other conditions that make the patient's life without treatment unfeasible. An adequate nutritional support to patients with CKD at any stage aims to maintain a good clinical condition and an attempt to delay the progression of the disease. The basis of a diet for patients with CKD is the restriction in this protein being of high biological value, low-phosphorus, high energy density, fiber and antioxidants combined with a good dietary practices that allow the patient a good quality of life

Uremic syndrome, arising from kidney malfunction, consists of a set of systemic changes caused by the accumulation of toxic substances to the body. Since, with the advance of medicine, the animals lived more reaching advanced age and entering thus on track of senility, chronic renal disease, became a common complaint in the routine of the ambulatory. This high rate of morbidity generates an increased need for clarification of pathophysiology involved in this disease. The components of the uremic syndrome include water and sodium imbalance, anemia, intolerance to carbohydrate, neurological disorders, disorders of the gastrointestinal tract, osteoarthritis, immunological incompetence and metabolic acidosis. The clinical manifestations occur in isolation or in combination. In most cases canines patients are subject to an assessment when the kidney disease has evolved to the final stage with uremic syndrome and installed already, under these conditions, the prognosis is reserved

The policystycal kidney disease that's a disease congenital autossomal dominant , no connected with the sex , what affect equally manly and females, especially the from race Persian and intersections with animals of that race. The polycystical kidney disease is broadcast the all issue from the individuals affected due at your character hereditary dominant. Yours signals clinical is linked together at the classic signals of Insufficiency Renal Account, such as: nefromegaly, poliury, anorexic, hematury and anemia , because in as much as the animals affected they tend developing this pathology among others secondary systemic problems . The means diagnostic, to ide ntify this pathology as varied, being used principally the of image, permitting a precociou diagnostic. Your treatment consists in master the symptoms caused by kidney insufficiencies Account and furnish, comfort and quality of life for the animals bearers, because it doesn’t have cur. Know the etiology, signals clinical, mediums diagnostic and the treatment is essential tools about to the screening of that disease and also to the future from race Persian and yours intersections obtained across her. The main objective this study was realize a bibliographic review about polycystical kidney disease linking a traditional forms of the diagnostic, treatment and control with new studies recently published about affected felines populations

Nitric oxide (NO) is a free radical gas, inorganic, which has seven electrons of nitrogen and oxygen eight, possessing an unpaired electron. This radical is produced from L-arginine by a reaction mediated by the enzyme NO synthase. NO it is about a radical of who acts abundant on a variety of biological processes, particularly when produced by endothelial cells plays a significant role in cardiovascular control, as a modulator of peripheral vascular resistance and platelet aggregation. This free radical has also a neurotransmitter and mediator of the immune system. NO kidney function has been considered in many physiological functions such as: (a) regulation of hemodynamics and glomerular function tubuloglomerular, (b) participation in pressure natriuresis (c) maintaining medullar perfusion (d) inhibiting sodium reabsorption tubular, and (e) acting as a modulator of the activity of the sympathetic nervous system. Given these functions, the occurrence of its deficiency is associated with chronic kidney disease (CKD) in vasoconstriction and consequently glomerular hypertension, high blood pressure (HBP), proteinuria and progression of renal dysfunction. This work has the scope to describe the role of NO in renal physiology and pathophysiology of CKD.

A doença de Wilson é uma doença hereditária autossómica recessiva que afecta o gene ATP7B, localizado no cromossoma 13. Caracteriza-se por uma alteração do transporte transmembranar do cobre, acumulando-se este no fígado e noutros órgãos, principalmente cérebro, rins e córnea. A prevalência mundial é de aproximadamente 30 casos por milhão de habitantes. Cerca de 60 a 70% dos casos são diagnosticados entre os 8 e os 20 anos de idade. Clinicamente, apresenta-se como doença hepática, neurológica ou psiquiátrica. O seu diagnóstico é baseado num alto índice de suspeição e na combinação de achados clínicos e laboratoriais. O exame gold standard para o diagnóstico é a biópsia hepática com doseamento do cobre. O tratamento consiste na terapêutica farmacológica permanente ou no transplante hepático. Existem actualmente três fármacos disponíveis: a penicilamina e a trientina (agentes quelantes) e o zinco. O tetratiomolibdato é um agente quelante ainda em investigação. A capacidade reprodutiva das mulheres com doença de Wilson tem melhorado com o aumento da eficácia destas terapêuticas e, como tal, a gravidez torna-se mais frequente. Esta parece não afectar o curso da doença e o principal problema que se coloca é a escolha da terapêutica mais adequada durante a gestação, dado que a segurança destes fármacos na gravidez não está garantida. Os autores descrevem 3 casos de grávidas com doença de Wilson, vigiadas na sua instituição, e discutem a controvérsia em torno do uso destes fármacos no tratamento da doença durante a gravidez e amamentação.
