Many volatile anesthetics have long been thought to affect pulmonary functions including lung ventilation (LV) and alveolar epithelial permeability (AEP). The purpose of this study is to examine the influence of volatile anesthetics on LV and AEP by noninvasive radionuclide lung imaging of technetium-99m labeled diethylene triamine pentaacetic acid radioaerosol inhalation lung scan (DTPA lung s...

Objective: Congenital hydronephrosis is a common prenatally diagnosed anomaly associated with an incidence of approximately 0.5-1% in newborns. The purpose of this study was to clarify the value of 99 m diethylenetriamine pentaacetic acid (99mTc-DTPA) in the assessment of renal function impairment of pediatric hydronephrosis. Methods: A total of 48 children with unilateral ureteropelvic junctio...

The early demonstration of lung involvement in systemic lupus erythematosus (SLE) patients is a difficult but important task. In the present study we attempted to identify abnormalities in pulmonary clearance of 99mTc-DTPA in SLE, correlating their clearance data with clinical findings and disease activity. Forty-six consecutive SLE patients with and without active disease (LACC score) and 30 n...

Introduction: Glomerular filtration rate (GFR) is the most important measure for early detection of deterioration of renal function. Patients with diabetic nephropathy need to be intensely monitored with GFR value. Many methods are used to estimate the GFR, all having their own advantages and constraints. The correlation of these methods with each other in patients with diabetic nephropathy nee...

Based on the previous demonstration of a renoprotective effect of arginine-glycine-aspartic acid (RGD) peptides in acute renal failure, experiments were designed to test the distribution and renal accumulation of the peptide. To accomplish this goal, in this study, RGD peptide was radiolabeled and its biodistribution and renal accumulation was determined in rats with ischemic acute renal failur...

Exogenous hydrogen peroxide (H2O2) causes airway epithelial damage in vitro. We have studied the effects of luminal H2O2 in the sheep trachea in vivo on tracheal permeability to low-molecular-weight hydrophilic (technetium-99m-labeled diethylenetriamine pentaacetic acid; 99mTc-DTPA) and lipophilic ([14C]antipyrine; [14C]AP) tracers and on the tracheal vascular response to luminal capsaicin, whi...

The lung clearance of technetium-99m diethylenetriamine penta-acetic acid (99mTc-DTPA) is a measure of respiratory epithelial permeability. Many factors may contribute to the wide range of normal values, including the method of correction for background activity. The aim of this study was to compare three methods of analysis, including their repeatability. 99mTc-DTPA lung clearance imaging was ...

OBJECTIVE To investigate the influence of bladder fullness on the diagnosis of urinary tract obstruction during dynamic renal scintigraphy with a diuretic stimulator. MATERIALS AND METHODS We studied 82 kidneys in 82 patients submitted to dynamic renal scintigraphy with a diuretic stimulator. We compared the proportional elimination of the radiopharmaceutical 99mTc-DTPA from the kidneys befor...

The precise measurement of glomerular filtration rate (GFR) and renal plasma flow (ERPF) usually requires continuous intravenous administration of adequate substances, with multiple blood and urine analysis, and does not allow measurement of separate renal function. Schlegel et al. and Gates described isotopic methods for the measurement of global and unilateral GFR and ERPF based on the determ...
