1. Renal biomarkers of male and female Wistar rats (Rattus norvegicus) undergoing renal ischemia and reperfusion
PURPOSE:To investigate biomarkers of acute renal injury in Wistar rats, subjected to left renal ischemia for 10 minutes, and then compare reperfusion at 24 hours, and at 5, 7, 14 and 21 days after the procedure.METHODS: Eight female and male rats between 60 and 81 days old were used in the Central Animal Facility of the UFMS. Assessed biomarkers included uri

2. Avaliação da reprodutibilidade dos parâmetros de adequação da hemodiálise crônica / Evaluation of reproducibility of adequacy Parameters in chronic hemodialysis
Justificativa: Doses inadequadas de diálise estão associadas a maior morbidade e mortalidade em pacientes com uremia terminal em tratamento hemodialítico. Atualmente os métodos mais utilizados para medir a adequação da hemodiálise baseiam-se no cálculo da depuração fracional de uréia (Kt/V) e da taxa de redução da uréia (URR). Nesse estudo aval

3. Effect of hypotonic expansion on sodium, water, and urea excretion in late pregnancy: the influence of posture on these results
Mineralocorticoid-treated, normotensive third trimester subjects positioned in lateral recumbency were studied before and during the infusion of 300 mEq of hypotonic saline. Urinary sodium excretion increased in all subjects from a mean value of 199 to 416 μEq/min. In 12 maximally hydrated subjects free water clearance (CH2O) and urine flow (V) increased fr

4. A study of the intrarenal recycling of urea in the rat with chronic experimental pyelonephritis.
The concentrating ability of the kidney was studied by clearance and micropuncture techniques and tissue slice analyses in normal rats with two intact kidneys (intact controls), normal rats with a solitary kidney (uninephrectomized controls), and uremic rats with a single pyelonephritic kidney. Urinary osmolality after water deprivation for 24 h and administ

5. Converting enzyme inhibition and kidney function in normotensive diabetic patients with persistent microalbuminuria.
The effects of a long term reduction in blood pressure on the kidney function of normotensive diabetic patients who had persistent microalbuminuria (30-300 mg albumin/24 hours) were studied in two groups of 10 such patients before and during six months of treatment with either 20 mg enalapril or placebo daily. Treatments were assigned randomly in a double bl

6. Effect of fetal exposure to gentamicin on kidneys of young guinea pigs.
Clearance experiments were performed with young pups born of guinea pigs given a daily injection of 4 mg of gentamicin per kg (body weight) from days 48 to 54 of gestation (term, 68 days). For 3-day-old animals, the glomerular filtration rate was similar to that measured in control guinea pigs of the same age whose mothers were given saline during the same p
