We describe the impact of cardiovascular pharmacologic support on peritoneal dialysis adequacy in 20 neonates who required postoperative renal replacement therapy following cardiopulmonary bypass exposure. Peritoneal dialysis was administered for 2.5 (2) days. Peritoneal dialysis creatinine clearance was 3.4 (2.1) ml/min/1.73 m(2) and ultrafiltration rate was 9.75 (10) ml/h. Residual creatinine...

The effects of changes in injection volume on the intramuscular ra(liosodiumii clearance rate was investigated in six normal young men. The clearance rate was found to be quite sensitive to the volume of solution injected, and an increase in the rate of clearance corresponding to a dlecrease in volume was uniformly noted. Rigid control of the injection volume is necessary Allen this method is u...

The intrinsic metabolic clearance of saquinavir, nelfinavir, and ritonavir was determined over a range of concentrations (0.02-20 microM) in both rat liver microsomes and fresh isolated rat hepatocytes in suspension. Clearance values were found to be concentration dependent for both systems, and at low concentrations, microsomal clearance was much greater (7-14-fold) than in hepatocytes. Kineti...

INTRODUCTION Extracorporeal shock wave lithotripsy (ESWL) is accepted as the gold standard treatment for renal stones that are smaller than 2 cm. Recently, retrograde intrarenal surgery (RIRS) has been introduced as another form of treatment. We report our experience in dealing with renal stones smaller than 2 cm using RIRS as the primary treatment and following failed ESWL. METHODS A retrosp...

Evaluation of right ventricular (RV) oxidative metabolism is limited by the inability to easily determine oxygen extraction by the RV myocardium and the complex morphology of this ventricle. Because left ventricular C-11 clearance rate constants closely correlate with myocardial oxygen consumption, it was postulated that C-11 clearance rate constants for the RV free wall should also reflect its...

BACKGROUND Because serious adverse reactions to allopurinol have been related to a reduce creatinine clearance rate and prolonged half life of oxypurinol, it has been recommended that the dose should be adjusted according to the rate of creatinine clearance. However, in some patients with gout the dose is not sufficient to reduce serum levels of uric acid (< or =390 micromol/l) and to halt dise...

objective(s):   recently, applications of mno2 nanoparticles and microparticles in industry, pharmacology, and medicine have considerably expanded. mn distribution and clearance from brain and spinal cord tissue compared with muscle tissue of rats after single subcutaneous injection of nanoparticles and microparticle of mno2. pain sensory threshold of rat was evaluated as neurologic consequence...
