1. Development of the urinary system in guinea pig females (Cavia porcellus)
RESUMO: Os porquinhos-da-índia são modelos animais amplamente utilizados em pesquisas relacionadas a biologia do desenvolvimento. O objetivo deste trabalho foi demonstrar o processo de formação e diferenciação dos órgãos urinários em fêmeas da espécie no período pré-natal. Foram utilizadas quatro fêmeas aos 25, 30, 45 e >65 DG (dias de gestaç�

2. Enalapril e captopril revertem o edema e a hiperplasia renais causados pelo antimoniato de N-metilglucamina em camundongos C57BL/6
ABSTRACT The aim of this study was to verify whether enalapril and captopril would reverse the renal damage caused by N-methylglucamine antimoniate in C57BL/6 mice. We used inbred C57BL/6 female mice, obtained from the Oswaldo Cruz Foundation (FIOCRUZ), Salvador, BA. The mice were divided into four groups as follows: Group1: received saline by the intramuscu

3. Low-Intensity physical activity beneficially alters the ultrastructural renal morphology of spontaneously hypertensive rats
INTRODUCTION AND OBJECTIVE: Kidney disorders can cause essential hypertension, which can subsequently cause renal disease. High blood pressure is also common among those with chronic kidney disease; moreover, it is a well-known risk factor for a more rapid progression to kidney failure. Because hypertension and kidney function are closely linked, the present

4. Effects of sirolimus alone or in combination with cyclosporine A on renal ischemia/reperfusion injury
Calcineurin inhibitors exacerbate ischemic injury in transplanted kidneys, but it is not known if sirolimus protects or exacerbates the transplanted kidney from ischemic injury. We determined the effects of sirolimus alone or in combination with cyclosporin A (CsA) on oxygenated and hypoxic/reoxygenated rat proximal tubules in the following in vitro groups c

5. Study of the Na+/H+ (NHE3) exchanger gene promoter region. / Estudo da região promotora do gene do permutador Na+/H+ (NHE3).
In view of the importance of the exchanger Na+/H+ (isoform 3), in reabsoption of NaCl and NaHCO3 in proximal tubules and consequently the acid-base balance, and cell volume, came the interest in identifying the region promoter essential for transcription of the NHE3 gene and the elements of the binding of transcription factors present in the same, in cells r

6. Avaliação de parametros funcionais e morfologicos da ação da angiotensina II sobre segmentos de tubulos proximais isolados e conservados em soluções de euro-collins e belzer / Funcional and morphological behavior of preserved PCT during treatment using angiotensin II and Losartan
Introdução: A qualidade da conservação obtida em um órgão e a duração do armazenamento seguro são dependentes do tipo de solução e tempo de conservação, estando sujeitas a intercorrências imprevisíveis. Em virtude disso, o parênquima renal e, particularmente, o túbulo contornado proximal (TCP), local onde ocorre necrose tubular aguda (NTA),

7. Estudo da toxicidade induzida por fosfolipase A2 isolada do veneno de Crotalus durissus terrificus em rim isolado de rato e em tÃbulos proximais isolados de coelho / Study of toxicity induced by phospholipase A2 isolated from Crotalus durissus terrificus snake venom on isolated rat kidney and on isolated rabbit proximal tubules
Apesar de muito se discutir sobre os efeitos citotÃxicos dos venenos ofÃdicos, pouco ainda à conhecido sobre os mecanismos de aÃÃo sobre as diversas cÃlulas, e em especial, sobre as cÃlulas renais. No caso particular da citotoxicidade dos venenos crotÃlicos, tem-se postulado a participaÃÃo de diversos metabÃlitos da hidrÃlise de lipÃdios de memb

8. Role of p21 and oxidative stress on renal tubular resistance after acute ischemic injury / Papel do p21 e do estresse oxidativo na resistência renal isquêmica
Renal tubular resistance has been studied for the understanding of ischemic acute renal failure (ARF). Subsequent ischemic episodes may induce renal resistance whose mechanisms seem to be related to cell alterations. P21 is a cell cycle inhibitor that may be induced by oxygen free radicals and may have a protective effect in ischemic ARF. This study aimed at

9. Study about the development of renais systems in bovines embryos (Bos indicus and Bos taurus) during the gestation period 10 and 50 days / Estudo do desenvolvimento dos Sistemas Renais de embriões bovinos (Bos indicus e Bos taurus) durante o período gestacional compreendido entre 10 e 50 dias
The present scientific study it has as objective to describe the development of the bovine Renais Systems, during the embryonic period. For in such a way, embryos collected in freezers of the region had been used, and after the collection the same ones had been photographed and measured using the Crow-Rump method (CR). For morphologic description they had be

10. Alterações histológicas de peixes como biomarcadores da contaminação aquática
Several streams from big cities are contaminated with industrial, domestic and agricultural effluents. The indiscriminated sewage and the release of substances considered risky into these streams may lead to damages in the water environment that may be considered as a great source of stress for the biotic community. The pollutants may cause lesions in the ti

11. Carcinoma renal dos ductos de Bellini
Two types primary epithelial tumours of the kidney have been distinguished, such as renal cell carcinoma (hypernephroma or Grawitz) deriving from proximal tubules and carcinoma arising in the urothelium of the kidney's collecting system. Mancilla-Jimenez e cols were the first to describe in 1976 an atypical papillary carcinoma of the kidney deriving from col

12. Estudo da pressão arterial e manipulação renal de sodio em ratos diabeticos induzidos pela administração de estreptozocina : implicações do sistema nitroxidergico
The role ofthe kidney in the control ofhydrosaline homeostasis in patients or experimental models with diabetes mellitus has been striking demonstrated by several studies. Recently, growing evidence suggesting that precocious tubular dysfunction may precede glomerular modifications and influence directly the renal function and cardiovascular homeostase. Howe
