Renal function was measured by clearance technique before and after acute myocardial infarction (MI) induced by left coronary artery ligation in male Sprague-Dawley rats. The animals were anaesthetized with halothane-nitrous oxide, paralysed with pancuronium and artificially ventilated. All
Sodium and water excretion were studied by standard clearance techniques in three experimental models where renal mass was reduced by superficial cortical necrosis (CN) or ischemic segmental infarction (SI). During hydropenia either CN or SI were able to conserve and regulate sodium to a very
Adverse cardiac remodeling after myocardial infarction (MI) can lead to the syndrome of heart failure (HF). Recently, changes in gut microbiota composition (dysbiosis) have appeared as a novel candidate that may be linked to the development of CR and HF. The aim of this trial was to evaluate the
To assess progression of renal disease and the effects of protein intake in a species phylogenically close to man, 10 young adult baboons (Papio hamadryas) were subjected to 20 to 30% infarction of the left kidney and, two months later, to right nephrectomy. They were then randomized to a synthetic
OBJECTIVE
To determine if selective renal papillectomy would impair urinary concentrating ability, thereby decreasing urinary calcium concentration.
METHODS
Left papillectomy was performed in dogs using either incisional (n = 6) or Neodymium:yttrium-aluminum-garnet (Nd:YAG) laser (n = 5) techniques.
Glomerular and tubule functions were assessed by micropuncture in rats with extensive myocardial infarction produced by ligation of the left coronary artery 4 weeks prior to study. When compared to sham-operated control rats, rats with myocardial infarction involving 40 +/- 4% of the left
1. To test the hypothesis that basal renin angiotensin aldosterone system (RAAS) activity impairs the acute natriuretic response to frusemide in patients with mild or moderate congestive heart failure (CHF), we studied eight adult volunteers with preserved renal function, stable New York Heart
The role of lipid abnormalities in the pathogenesis of focal glomerulosclerosis was investigated in the rat remnant kidney model of chronic renal failure. Rats subjected to right nephrectomy and two-thirds segmental infarction of the left kidney (5/6 nephrectomy) were treated for 10 weeks with the
To characterize actions of growth hormone (GH) and insulin-like growth factor ( (IGF-I) on renal function in rats with normal and reduced renal mass, we administered recombinant bovine growth hormone (bGH) or human IGF-I (hIGF-I) to normal rats or to rats that had undergone unilateral nephrectomy
1. As the majority of drug molecules are relatively small and lipophilic, capillary uptake in those regions with a continuous endothelium, such as the heart, has generally been regarded as taking place by flow-limited transcellular capillary transport. Little attention has been paid to myocardial
BACKGROUND
Transplantation of developing metanephroi into adult hosts has been proposed as a means to augment host renal function.
METHODS
We implanted whole metanephroi from embryonic day 15 (E15) rats subcapsularly in kidneys or into the omentum of non-immunosupressed adult rat hosts. At the time
Methods of glomerular filtration rate measurement by 51Cr EDTA elimination, inulin clearance and creatinine clearance were compared with and without captopril pretreatment in 10 chronic heart failure patients and in 20 patients after transmural myocardial infarction. Strong intermethod correlations
One or more episodes of sublethal ischaemia and reperfusion delay infarct development during subsequent, sustained ischaemia in the heart and skeletal muscle. The present study tested whether or not such ischaemic preconditioning (IP) also protects the kidney. Enflurane-anaesthetized pigs underwent
OBJECTIVE
The aim of this study is to determine the most accurate renal function formula that predicts short- and long-term mortality in a wide spectrum of acute coronary syndrome (ACS) patients.
RESULTS
We analyzed 8,726 consecutive patients (46.3% ST-elevation myocardial infarction [STEMI] and
To assess the progression of renal disease and the effects of protein intake in a species phylogenically close to humans, 14 adolescent baboons (Papio hamadryas) were subjected to infarction of one third of the left kidney and, 2 months later, to right nephrectomy. They were then randomized to a
