Maternal undernutrition affects the foetal development, promoting renal alterations and adult hypertension. The present study investigates, in adult male rats, the effect of food restriction in utero on arterial blood pressure changes (AP), and its possible association with the number of nephrons, renal function and angiotensin II (AT1R/AT2R), glucocorticoid (GR) and mineralocorticoid (MCR) receptors expression. The daily food supply to pregnant rats was measured and one group (n=5) received normal quantity of food (NF) while the other group received 50% of that (FR50) (n=5). The AP was measured weekly. At 16 weeks of life, fractionator’s method was used to estimate glomeruli number in histological slices. The renal function was estimate by creatinine and lithium clearances. Blood and urine samples were collected to biochemical determination of creatinine, sodium, potassium and lithium. At 90th and 23rd days of life, kidneys were also processed to AT1R, AT2R, GR and MCR immunolocalization and for western blotting analysis. FR50 offspring shows a significant reduction in BW (FR50: 5.67 ± 0.16 vs. 6.84 ± 0.13g in NF, P<0.001) and increased AP from 6th to 12nd week (6thwk FR50: 149.1 ± 3.4 vs. 125.1 ± 3.2mmHg in NF, P<0.001and, 12ndwk FR50: 164.4 ± 4.9 vs. 144.0 ± 3.3 mmHg in NF, P=0.02). Expression of AT1R and AT2R were significantly decreased in FR50 (AT1, 59080 ± 2709 vs. 77000 ± 3591 in NF, P=0.05; AT2, 27500 ± 95.50 vs. 67870 ± 1509 in NF, P=0.001) while the expression of GR increased in FR50 (36090 ± 781.5 vs. 4446 ± 364.5 in NF, P=0.0007). The expression of MCR did not change significantly. We also verified a pronounced decrease in fractional urinary sodium excretion in FR50 offspring (0.03 ± 0.02 vs. 0.06 ± 0.04 in NF, p=0.03). This occurred despite unchanged creatinine clearance. The study led us to suggest that fetal undernutrition, with increased fetal exposure... (Complete abstract click electronic access below)

As infecções do trato urinário (ITU) são definidas como a invasão e posterior multiplicação de microorganismos nos tecidos das vias urinárias, sendo a bactéria gram-negativa E.coli o principal uropatógeno envolvido nessa infecção. A avaliação para a presença de ITU é feita através do quadro clínico característico desse tipo de paciente e o exame de cultura de urina. As amostras positivas para as culturas são avaliadas quanto ao perfil de sensibilidade aos antimicrobianos dos agentes etiológicos encontrados. Descrever a porcentagem de ocorrência dos agentes etiológicos e o perfil de sensibilidade aos antimicrobianos das Infecções do Trato Urinário em pacientes ambulatoriais de Botucatu e região. Foram incluídas neste estudo culturas de urinas de pacientes atendidos em UBS de Botucatu e região Pólo Cuesta, no período de Janeiro de 2008 a Maio de 2010. As culturas positivas foram avaliadas quanto a porcentagem de ocorrência dos uropatógenos segundo sexo, faixa etária e origem. Foi utilizado o teste do qui-quadrado para verificar associação entre cada antimicrobiano e as porcentagens de sensibilidade e resistência encontradas. Foram avaliadas 11.768 culturas de urina provenientes de 11 municípios da região, sendo consideradas as culturas positivas (28%). Quanto à ocorrência dos agentes etiológicos verificou-se que a E.coli é responsável 58,76% dos casos. A distribuição dos uropatógenos segundo sexo revelou maior ocorrência de E.coli nos dois sexos. O segundo agente etiológico de maior ocorrência foi, nos homens o Proteus mirabilis e nas mulheres, o S. saprophyticus. Dentre as faixas etárias, a E.coli foi o patógeno de maior ocorrência. O perfil de sensibilidade aos antimicrobianos revelou que a E.coli é mais sensível a Ertapenem, Imipenem, Meropenem, Fosfomicina, Amicacina, Ceftriaxona, Nitrofurantoína e Norfloxacina; e mais resistente...

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
