background: diabetic nephropathy is considered to be the most common cause of end stage renal disease (esrd). proteinuria is declared as the most marked risk factor in progression towards esrd. the aim of this study was to evaluate the efficacy of pentoxifylline for reduction of proteinuria in type ii diabetic patients. methods: from may 2007 to june 2008, this randomized clinical trial study w...

The aim of the study was the explain the mechanism related to therapeutic effects of Uremic Clearance Granules (Niaoduqing Keli in Chinese) on adenine-induced Chronic Renal Failure in rats. Thirty 8-week-old male Wistar rats were selected and randomly divided in to 3 groups: Normal Control Group (NCG)consisted of 10 rats, Chronic Renal Failure Pathological Control Group (PCG) 10 rats, and Uremi...

OBJECTIVES Available data on colistin pharmacokinetics in patients undergoing continuous renal replacement therapy (CRRT) are limited. Our aim was to study colistin pharmacokinetics in critically ill patients treated with colistin methane sulphonate for Gram-negative sepsis and undergoing continuous venovenous haemodiafiltration for acute renal failure. PATIENTS AND METHODS Three patients wer...

In humans, the kidney is involved in leptin clearance from the body. The present study was performed to assess the renal extraction of leptin in hypertensive patients with or without renal artery stenosis. Sixty-five hypertensive subjects (39 males and 26 females) underwent catheterization of the renal artery and both renal veins with blood sampling for measuring leptin levels. Blood flow to bo...

Pancreatic and salivary amylase/creatinine clearance ratios in patients with various degrees of renal impairment were compared with those obtained for control subjects. In chronic renal insufficiency (mean GFR 30 ml/min +/- 15 SD; n = 13) the clearance ratios for pancreatic (mean 3.5 +/- 1.85 SD) and salivary (mean 2.3 +/- 1.3 SD) amylase were significantly higher (P less than 0.05) than those ...

Early data are now appearing relating to the measurement of biomarkers of acute kidney injury during renal replacement therapy. These data go some way in describing the clearance of these molecules during renal support. Understanding the potential clearance, or otherwise, of these proteins may lead to directing our therapies in the future particularly with regard to cessation of renal support. ...

To characterize the effect of orally administered probenecid on the pharmacokinetics of cefoxitin in healthy male volunteers, we administered to one group of six subjects 2 g of cefoxitin by intravenous (i.v.) bolus either alone, with 1 g of probenecid concomitantly, or when 1 g of probenecid was administered 1 h previously by using a crossover design. Likewise, we administered to a second grou...

UNLABELLED Glomerular filtration rate (GFR) is an important index of renal function. Twenty-four-hour creatinine clearance overestimates GFR in patients with poor renal function. Inulin and iothalamate clearances are accepted reference standards for determining GFR but are expensive and laborious. We have previously reported that GFRs obtained by measuring the disappearance of 99mTc-DTPA from u...

The kidneys are the most important extrahepatic site of insulin breakdown and play a significant role in regulating the systemic insulin level in normal subjects. In man, a renal arteriovenous insulin concentration difference of about 30% has been measured, and since 'insulin clearance' values are less than the glomerular filtration rates, insulin is probably removed from blood by a combination...

Diabetic nephropathy (DN) is one of the major causes of end stage renal disease. Angiotensin converting enzyme (ACE) inhibitor and angiotensin receptor blocker (ARB) are preferred for delaying progression of DN. This study compared the preventive renal effects of telmisartan (10 mg/kg, p.o.), an ARB that completely blocks angiotensin action, and benazepril (5 mg/kg, p.o.), an ACE inhibitor, whi...
